This is especially critical for the Chesapeake Bay estuary; underwater grasses provide habitat for fish and other aquatic animals, stabilize sediments, and help clarify the water. Since the 1970s, pollution and human development have decimated the population of underwater grass in the Chesapeake Bay, further degrading the water quality. States surrounding the Bay have been working together since 2010 to restore its ecosystems.
One study, published in the Proceedings of the National Academy of Sciences analyzed the positive impact of long-term nutrient reduction on valuable ecosystems in the estuary.
The study, led by Jonathan Lefcheck, Ph.D., formerly of the Virginia Institute of Marine Science (VIMS) and now at the Bigelow Laboratory for Ocean Science, showed a 23-percent decrease in average nitrogen levels and an eight-percent reduction of average phosphorus levels, which resulted in a significant increase of Submerged Aquatic Vegetation (SAV) in the Bay. Data analysis indicated that this ecosystem recovery is the biggest resurgence of underwater grasses ever recorded.
The research team said that cutting pollution, as well as conservation incentives, promoted the return of aquatic vegetation, which then led to a healthier Chesapeake Bay.
"It's a humbling and unique opportunity," stated Lefcheck. "These efforts began before I was even born, but we are at a stage now where all of these different threads can be pulled together to unveil a picture of unprecedented success. This is a message of hope, and I look forward to a future when the Bay is filled with grasses, something I never thought I would see during my lifetime."
The scientists determined how the reduction of pollutants – such as nitrogen and phosphorus – is the key driver to this ecosystem recovery. The analyzed data in two ways: One focusing on the flow of nutrients from the land to the waterways; and one showing what happens to SAV once the nutrients reach the water.
Senior co-authors Dr. William Dennison of the University of Maryland Center for Environmental Science and Dr. Robert "JJ" Orth of VIMS have worked on underwater grasses and water quality in the Chesapeake Bay ecosystem restoration project for decades.
According to Dennison: "J.J. and I have had the distinct privilege of facilitating research that confirms a direct correlation between conservation actions undertaken by a broad partnership and ecosystem responsiveness that is leading to positive ecological outcomes."
"The EPA Chesapeake Bay Program is working and can serve as a model for the rest of the world," he added.
Orth noted that he feels proud of the team of both new and experienced researchers for the progress and accomplishments thus far of the restoration project. "I really feel the torch is being passed to a next generation of scientists who bring both the passion and knowledge needed to continue the vital work of marine science required to keep our Chesapeake Bay flourishing. What has been a lifetime of work for Bill and me can now be analyzed and managed with analyses of long term data sets in creative ways to highlight this wonderful recovery."
The Chesapeake Bay Program is a partnership between the states of Delaware, Maryland, New York, Pennsylvania, Virginia, and West Virginia; the District of Columbia; and the federal government, represented by the Environmental Protection Agency (EPA).
The program relies on funding from community groups, local government and non-governmental organizations, which engage in pollution mitigation efforts, such as redesigning urban surfaces to reduce stormwater runoff and subsidizing farmers to grow winter cover crops that help retain nutrients on fields.
The study on the Chesapeake Bay has spanned decades of analysis and investigation on the estuary, and the aforementioned study shows a positive impact of management actions on the huge resurgence of underwater vegetation. The ongoing restoration efforts provide an outline for effective pollution abatement and may be applied to other polluted bodies of water, in an effort to restore more aquatic ecosystems in other places.

Degree of Threat: A : Very threatened throughout its range communities directly exploited or their composition and structure irreversibly threatened by man-made forces, including exotic species
Comments: Intense fishing of spawning aggregations has severely threatened the viability of the species in particular locations (Olsen and LaPlace 1978; Aguilar-Perera 1990; Fine 1990; Sadovy 1990, in press; Luckhurst 1996). For example, the decline in Bermuda is due to the intensive fishing of spawning aggregations with fish pots (Luckhurst 1996), and the decline in spawning aggregation size off Bay Islands, Honduras, is attributable to intense fishing of spawning aggregations (Fine 1990). In the 1960s, the introduction of spearguns led to sharp declines in aggregations; speargun fishing removes reproductively active individuals and likely affects future fishery yields. Removal of larger individuals could lead to a lack of experienced adults to lead first time spawners to spawning areas (Stevenson et al., in press). This fish is an important top-level, resident predator in coral reef environments; removal can cause corresponding changes in reef fish community structure (Carr and Hixon 1995). Indications of overfishing include: declines in abundance and size, decreases in number and weight of catch, declines in catch per unit, and loss of spawning aggregations. Catch throughout much of range often yields only immature (< 40 cm total length) individuals (Sadovy, in press). Considered overfished in the Florida Keys based upon spawning potential ratio below 30 percent, despite seven-year moratorium in Florida and federal waters (Ault et al. 1998). Overfishing for at least 20 years have raised concerns that the species could become locally or commercially extinct range-wide (Sadovy, in press).


Assessment Carbon Sequestration Rate of Different Cultivable Seaweeds of Cox’s Bazar Coast, Bangladesh
Seaweed has the ability to use carbon from the environment through photosynthesis to produce biomass. This study aims to estimate the carbon sequestration rate by different cultivable seaweeds as a strategy to mitigate the impact of ocean acidification and global climate change. This study also determines the influence of carbon sequestration on different environmental factors. The study was undertaken at Cox’s Bazar coast. Locally available five seaweed species namely Gracilaria tenuistipitata, Ulva compressa, U. intestinalis, U. lactuca and polysiphonia sp. were cultured with the longline and net method for three cultivation periods, starting from October to March, 2020-2021. Each cultivation period was taken about 45 days. Seaweed samples were collected every 15 days from day 0 (initial), 15,30 to 45 (replanting) for every cultivation period to assess the carbon content of seaweeds. The results show that the sequestration rate of U. intestinalis is significantly higher than the others in the longline and net method. Highest concentration found in the day-45 and lowest concentration is in the day-15. Descending order of the Carbon sequestration in the cultivated seaweeds U. intestanalis>U. compressa>G. tenuistipitata>U. lactuca>Polysiphonia sp. Trends of carbon sequestration rate were influenced by different seaweed variants. Generally, U. intestinalis has higher sequestration rate than other four seaweed variants. Highest concentration found in the day 45 and lowest concentration is in the day 15. Two way-ANOVA results showed the comparisons of the rate of the carbon sequestration among the different cultivated seaweeds at Cox’s Bazar coast among different stations and seasons. Correlation matrix and multiple regression analysis showed the influence of different environmental factors. If the cultures of seaweed increases worldwide in a large scale it will be a powerful tool in controlling ocean acidification and economically benefitted.

The evolution of oceanic gabbros : in-situ and ancient examples
Author(s)Kvassnes, Astri Jæger Sweetman, 1972-
Woods Hole Oceanographic Institution.
Henry J.B. Dick.
MetadataShow full item record
This study is a geochemical investigation into the accretion of lower oceanic crust and processes of shallow melt-rock reaction at mid-ocean ridges. Major-, trace-elements, and isotopes from whole-rocks and minerals from the Lyngen Gabbro, a 480-My old dismembered ophiolite from the Scandinavian Caledonides, indicate that this igneous complex was produced from hydrous supra-subduction zone magmas, a remnant of an incipient ocean-arc. Such ophiolites are better models for the structural evolution than the geochemical evolution of the lower oceanic crust at mid-ocean ridges. Minerals in gabbros from Atlantis Bank, Southwest Indian Ridge, a modern, in-situ example of lower ocean-crust, were analyzed for major and trace-elements. The MELTS algorithm indicates that these gabbros formed by near-fractional crystallization at mid-crustal pressures. The gabbroic crust is more evolved than the lavas and represents melts fractionated 50-95% relative to a mantle-derived melt-composition, supported by trace-element models. This argues against the often-cited gabbro-glacier accretion model, where mantle-derived melts are transported to a shallow melt-lens and fractionates there before eruption. There remain >770-m of additional primitive cumulates below 1500-m deep Hole 735B or within the underlying mantle. Thus, the seismic Moho, beneath Hole 735B, could be the crust-mantle boundary, rather than an alteration front as suggested elsewhere. The Atlantis Bank gabbros have augites that are more primitive than plagioclases and olivines with which they coexist. Melt-rock interaction, where ascending melts dissolve the pre-existing gabbroic rocks and create hybrid magma may have caused this. Dissolution-experiments for plagioclase-olivine and plagioclase-augite mineral pairs(cont.) were performed at 1180⁰-1330⁰C and 20-min - 24hrs. Dissolution occurs rapidly and out of equilibrium, with the dissolution rates dependent on the [delta]T above the solidus. Rocks with small grain-boundary areas (coarse grained or nearly mono-mineralic) heat internally when enclosed in hot magma, causing xenoliths or wall-rock to melt and disaggregate. The dissolution-derived magma crystallizes minerals more refractory-looking than the melts that precipitated the original gabbroic rocks. Assimilation of gabbroic rocks increases the Na content and decreases the Fe content of the melt that digests it, thus basaltic glasses formed after this hybridization will falsely reflect a lower degree and pressure of mantle melting.

Despite Pandemic Delays, Coalition Uses Oyster Shells to Build Reef
NEW ORLEANS — Despite a delay caused by the COVID-19 pandemic, construction of the Coalition to Restore Coastal Louisiana’s third reef made from recycled oyster shells is underway in Barataria Bay. The 800-ton “living shoreline” – which is two-thirds of a mile long – is designed to create habitat for new oysters and other aquatic life and stabilize an eroding coastline.
Construction of CRCL’s latest reef was slowed by the coronavirus pandemic even before cases of COVID-19 were confirmed in Louisiana. The facility in China that manufactures the gabions — steel construction cages used to hold oyster shell in place — was forced to shut down in February, halting production of a vital piece of the project. Shortly after, cases of coronavirus were detected in Louisiana, causing the closure of CRCL’s office, the cancellation of volunteer events and the rescheduling of this year’s State of the Coast conference. Additionally, the Oyster Shell Recycling Program’s restaurants partners shut down, and the oyster industry was left devastated.
Now, the gabions have been delivered to Louisiana, where CRCL has been working with contractor Coastal Environments Inc. to fill the cages at a shell pile in Buras. The cages, filled with oyster shells collected by New Orleans restaurants that have partnered with the Oyster Shell Recycling Program, are being deployed at the reef site in Barataria Bay.
“The start of construction of our Barataria reef has been a gratifying moment for CRCL,” said Dr. Deborah Visco Abibou, CRCL restoration programs director. “Coastal land loss is a slow-moving but urgent crisis that affects our entire state, so we have to use every tool available to tackle the problem. We hope this reef demonstrates the effectiveness of a nature- based solution to slow shoreline erosion and re-establish functional reef ecosystems that can sustain themselves — and us — into the future.”
CRCL’s Oyster Shell Recycling Program began in 2014 and has collected nearly 10 million pounds of oyster shells from restaurants in the New Orleans area. In 2016, CRCL constructed its first oyster reef using recycled shell, a half-mile long reef in Lake Athanasio within the St. Bernard Parish’s Biloxi Marsh. A second reef, completed last year, is protecting the Pointe-au-Chien Indian Tribe’s culturally significant mound complex from erosion and sea level rise. CRCL recently collected positive data on that reef and is planning the construction of a fourth reef in Plaquemines Parish.
“The dramatic ongoing losses to Louisiana’s coastline necessitate a variety of restoration solutions and interventions: diversions, shoreline armoring, marsh creation and reef building — just to name a few,” said Steve Cochran, campaign director for Restore the Mississippi River Delta, a campaign to which CRCL belongs, along with the Environmental Defense Fund, the National Audubon Society, the National Wildlife Federation and Pontchartrain Conservancy. “Construction of the living shorelines, in addition to other priority restoration projects and community resilience measures, will help combat Louisiana’s land loss crisis, rebuild land that has been lost and sustain new land into the future.”

Lincoln City, OR —
On January 13, 2012 Steve Harnack was surfing at Nelscott Reef near Lincoln City, Oregon. The reef is approximately 0.5 miles offshore and creates a reef break with waves frequently 20 feet high. It was 10:00 AM and he had been on the water about 20 minutes. The sky was clear with an air temperature in the mid-40s Fahrenheit. Water temperature was approximately 48 degrees Fahrenheit with 15 – 20 feet of water visibility and a depth of 40 – 50 feet. There were two jet skis in the area assisting about 8 other surfers. No marine mammals were observed in the area. Harnack reported; “I had traveled beyond the reef about 200 yards by duck-diving through several waves about 20 feet high. I noticed my board dragging as I moved through the water. I had a jet-ski tow me back to the beach where I noticed a section on the bottom of my board had been struck by a shark. A portion of the fiber-glass had been removed and tooth impressions were also present.”
Additional information, including photographs of the board's damage, will be posted when available in a few days. Please report any shark sighting, encounter, or attack to the Shark Research Committee.


UKZN’s Marine Biology, Aquaculture, Conservation Education and Ecophysiology (MACE) Laboratory was featured in a recent episode of the TV show Carte Blanche which highlighted microplastics and the danger they pose to marine life.
The TV segment explained what microplastics are and dealt with the dire effects of microplastic contamination, revealing that by 2050 there will be more plastic in the ocean than marine life, affecting up to 90% of sea birds.
Plastics, widely used without long-term consideration of impact; take hundreds of years to degrade and are washed out to sea where they collect in five major gyres worldwide, one of which covers an area larger than South Africa and in places is more than three metres deep.
Marine life cannot distinguish between plastic and food, consuming the plastic and then starving to death.
Microplastic (particles smaller than 5mm long) are either manufactured to this size (primary), or broken down from larger plastics (secondary). They are too small to be filtered at sewage plants, flowing into rivers and ultimately the ocean.
MACE researchers have found that 30% of fish they study contain microplastics. All 16 species under analysis had microplastics in their guts, irrespective of where they feed in the water column.
Microplastics, found in beauty and household products and synthetic fibres released from clothing in washing cycles, have been banned in several countries, but not in South Africa.
Moodley explained that microplastic contamination of marine life started with primitive organisms at the base of the food chain - the effects were multiplied up the food chain as contaminants accumulated, affecting development and fertility of larger predators. Microplastics both release and absorb dangerous chemical pollutants from the surrounding water, making them up to one million times more toxic than the surrounding water.
The TV feature touched on the research of postgraduate students Mr Sipho Mkhize, Ms Kaveera Singh, Ms Gemma Gerber and Mr Mathew Coote. In the video, Mkhize dissected a fish caught in the Durban harbour, demonstrating the extent of the microplastics in its stomach, Singh discussed finding nylon clothing fibres in the Umgeni River, and Gerber spoke about the impact of microplastics on mussels, an important local food source.
Fish, including those contaminated, are a major food source for many South Africans. A CSIR research project featured on the programme recommended less than five fish meals from affected systems per person per month to avoid adverse health effects.
Despite the challenges, Robertson-Andersson is positive. ‘Twenty years ago, we had things like glass and tin cans and plastic bottles on the beaches,’ she said. ‘With programmes such as Reduce, Reuse, Recycle, people have become more aware of their plastic products. We can do something about it, but it’s up to each individual person, rather than big organisations.’
Moodley, Robertson-Andersson and their students are involved in many beach clean-up events, collecting data and partnering with Durban Umgeni Conservation Trust (DUCT) and Paddle for the Planet to clean up river systems and remove plastic waste before it reaches the ocean.
‘We have only one planet we call home and we all need to do our little bit to keep it healthy, clean and sustainable,’ said Moodley. ‘We encourage individuals and organisations to join us in these clean-up activities to ensure that we DO make a difference.’

Single-beam bathymetry data collected in 2009 in the vicinity of Wainwright, Alaska
Bathymetry data were collected in the Wainwright Inlet, the mouth of the Kuk River, and in the nearshore region off Wainwright, Alaska, in August of 2009. Bathymetry was measured with a single-beam echo-sounder (10 Hz 144 ODOM Echotrac CV-100) mounted on the stern of a small vessel and synchronized to a 145 Real-Time Kinematic (RTK) Global Positioning Systems (GPS). The depth is measured relative to approximate Mean Sea Level (see attribute accuracy report in this file for further details on the MSL), and ...


Researchers from the University of California, Santa Barbara (UCSB) and Texas A&M University report that methane gas concentrations in the Gulf of Mexico have returned to near normal levels only months after a massive release occurred following the Deepwater Horizon oil rig explosion.
The study into the methane concentrations was led by oceanographers John Kessler of Texas A&M and David Valentine of UCSB. The findings show that more than 200,000 metric tons of dissolved methane were removed through the action of bacteria blooms that completely consumed the immense gas plumes the team had identified in mid-June.
At that time, the team reported finding methane gas in amounts 100,000 times above normal levels. But, about 120 days after the initial spill, they could only find normal concentrations of methane.
’What we observed in June was a horizon of deep water laden with methane and other hydrocarbon gases,’ Valentine said. ’When we returned in September and October and tracked these waters, we found the gases were gone. In their place were residual methane-eating bacteria, and a one million ton deficit in dissolved oxygen that we attribute to respiration of methane by these bacteria.’
Kessler added: ’Based on our measurements from earlier in the summer and previous measurements of methane respiration rates around the world, it appeared that [Deepwater Horizon] methane would be present in the Gulf for years to come. Instead, the methane respiration rates increased to levels higher than have ever been recorded, ultimately consuming it and prohibiting its release to the atmosphere.’
The research team collected thousands of water samples at 207 locations covering an area of about 36,000 square miles. It based its conclusions on measurements of dissolved methane concentrations, dissolved oxygen concentrations, methane oxidation rates and microbial community structure.
The Deepwater Horizon offshore drilling platform exploded on 20 April 2010, about 40 miles off the Louisiana coast. The blast killed 11 workers and injured 17 others. Oil was gushing from the site at the rate of 62,000 barrels per day, eventually spilling an estimated 170 million gallons of oil into the Gulf. The leak was capped on 15 July 2010 and the well was permanently sealed on 19 September.

Geomorphic features of the Antarctic margin and Southern Ocean 2012
Authors / CoAuthors
Publicly available bathymetry and geophysical data has been used to map geomorphic features of the Antarctic continental margin and adjoining ocean basins at scales of 1:1-2 million. The key bathymetry datasets used were GEBCO08 and ETOPO2 satellite bathymetry (Smith & Sandwell 1997), in addition to seismic lines in key areas. Twenty-seven geomorphic units were identified based on interpretation of the seafloor bathymetry with polygons digitised by hand in ArcGIS. Seafloor features were classified largely based on the International Hydrographic Organisation (2001) classification of undersea features, and expanded to include additional features, including those likely to have specific substrate types and influence on oceanography. This approach improves the technique as a predictor of physical conditions that may influence seafloor communities. The geomorphic map has been used for developing a benthic bioregionalisation and for developing a representative system of Marine Protected Areas for East Antarctica.
Slight modifications have been made since original publication in O'Brien et al. 2009 and Post et al. 2014. These include:
- updating of some feature names;
- combining "wave affected banks" with "shelf banks"
- Combining "coastal terrance" with "island coastal terrane" as "Coastal/Shelf Terrane"
- replacing canyon vectors with polygons by using a buffer around the vectors

The Big Beach Clean 2022
16th – 18th of September 2022
The Big Beach Clean is an annual call-to-action organised by Clean Coasts, calling people all around Ireland to host a beach clean and take part in a worldwide citizen science project as part of Ocean Conservancy’s International Coastal Cleanup, by simply recording the marine litter they collect to help shape future policies and campaigns to help protect our ocean.
This big beach clean day helps to heighten awareness about the issue of marine litter, and serves as an indicator of the magnitude of the problem and help shape future policies and campaigns.
Reasons to join go beyond the environmental side of the initiative, and everybody in the community would benefit from taking part – our ocean supports livelihood and businesses, it feeds billions of people, it offers a playground for people engaged in water sports and inspiration for artists, it helps our mental health, and much more.
Registration is open to all residents of Ireland, no matter how far from the coast they may be based. Getting involved in the Big Beach Clean is a way for residents of non-coastal counties to help prevent litter entering our waterways and seas by holding a clean-up no matter where they are in the country and tackling the problem at source.
Some of the frequently asked questions include …
Can I join an existing clean-up?
Yes! Closer to the date, Clean Coasts Ireland will be releasing a map of public events around the country that you can join. As well as that – we at Leave No Trace Ireland are running our own event! Join us on Friday 16th of Sept, 2pm, The Point, Westport.
How can I get involved in the citizen science project?
Can I join if I’m not based on the coast?
Yes! Litter from towns and cities very often makes its way to our ocean, carried by the wind, waterways, sewage systems, and more. No matter how far from the coast, your clean up will help tackle marine litter at its source.
What can I expect in my beach clean kit?
Marine Litter Data Collection Card
During the Big Beach Clean, Clean Coasts volunteers are asked to be part of an excellent round the world citizen science data collection project and to carry out marine litter surveys to quantify the amount and types of litter on Irish beaches. These surveys are aimed at heightening awareness about the issue of marine litter and serve as an indicator of the magnitude of the problem. We also encouraged our groups to use the Clean Swell App by Ocean Conservancy.
This year, Clean Coasts are hosting a series of events, where you will find a Clean Coasts officer that will help you collect information about marine litter. Make sure to check their website and social media as we get close to the dates!
To learn more, check out the Clean Coasts Website.
Join us on Friday 16th of Sept, 2pm, The Point, Westport.
Click here to register your beach cleaning event, and get a free beach cleaning kit!
Once you’ve completed your event, you can submit your big beach clean data online here.

Can you swim during high tide?
For swimmers, the water is safest during a slack tide, during which the water moves very little. … During high tide, the waves break too close to shore to offer much of a ride. During low tide, uncovered rocks or seaweed may get in the way. Waves with long intervals and large swells are ideal.
Is it dangerous to swim in the sea?
As water flows from land to coastal waters, it is often contaminated by untreated sewage from boats, pets, failing septic systems, fertilizers, and spills from hazardous substances. High levels of bacteria and other chemicals in the water can cause gastrointestinal illnesses in those who swim directly in the water.

How close to shore Can sharks get?
The swimming patterns of dogs can also draw sharks. Don’t think you’re safe just because the water is shallow — shark attacks can occur in less than three feet of water. While shark activity tends to be greater a few hundred yards from shore, stay alert even if you’re in thigh-deep water.
How can swimmers stay safe in the ocean?
Top Things to KnowSwim in designated areas with a lifeguard present.Always swim with a buddy.Avoid areas with moving water, waves or rip currents.Stay within your fitness and swimming capabilities.
What time of day is the ocean calmest?
Usually calmest in the early morning and picks up late afternoon.
Is swimming in the sea at night dangerous?
It isn’t safe to swim in the ocean at night. Swimming in the ocean at night can pose a greater risk than swimming during daylight hours, especially for inexperienced swimmers. This is due to the loss of vision in the darkness, the lack of people nearby, and the nocturnal behavior of ocean predators.
Do sharks come closer to shore at night?
Sharks are at the top of the food chain in the ocean and must be respected. … Many species of shark are known to come closer to shore during dusk, dawn, and night time hours. Do not swim or surf during these high risk time frames. Make sure that the beach you are going to swim at is patrolled by lifeguards.
Do sharks swim in shallow water?
Research has found that most swimmers are attacked by sharks in shallow water for a number of reasons. … Most shark attacks occur close to shore or near sandbars or areas with nearby deep drop offs, because that’s where sharks’ prey is often located, according to The Huffington Post.
Should I swim at high or low tide?
Do be aware, however, that while it’s generally safer to swim on a slack tide, the acutal times of slack water may vary from the official high or low tide times depending on local geography and weather conditions.
What is the safest time of day to swim in the ocean?

The Virginia Aquarium's Stranding Response Team asks residents who find beached seals to leave them alone.
Seals have been spotted recently in local waters and on land at Chesapeake Beach, Sandbridge and Croatan, where they take breaks to rest, an aquarium release says. Because some seals may be too tired or sick to get back in the water, the stranding team is asking for sightings to be reported.
Residents should not feed them or discard bait in the water near seals.
To report a sighting, call the team any time at 757-385-7575. The aquarium is offering boat trips on March 12 and 13 that will include areas where seals are known to visit.

UNCW/NOAA scientific permit No. 948-1692-00
Herman Melville may have made the sperm whale (Physeter macrocephalus) famous with Moby Dick, but there are other good reasons why you may not be familiar with the huge predator’s smaller cousins, the pygmy and dwarf sperm whales (Kogia breviceps and Kogia sima). Though they inhabit wide ranges and depths of temperate and tropical oceans along continental shelves and slopes, they are rarely sighted.
Scientists didn’t even recognize that the two species were separate until 1966. The pygmy species is a bit larger, and there are differences in morphology and genetics.
Dwarf and pygmy whales have been among the most commonly stranded marine mammals along the coast of Virginia and North Carolina. That gave three scientists from the University of North Carolina Wilmington a look at what the whales eat. Their study appears in the April Marine Mammal Science.
After marine mammals become stranded, their bodies are collected and necropsied, and the contents of their stomachs are saved. Michelle D. Staudinger and her colleagues looked through a stockpile of those stomachs, collected from 22 pygmy and 9 dwarf sperm whales from 1998 to 2011, and tallied up what the whales had been eating before they died.
Mostly the whales had been eating cephalopods, which Staudinger separated into species based on the hard beaks left behind after the soft bodies had been digested. To do that, she compared those beaks to her own reference samples (I guess there’s a collection for everyone) and to samples collected by whalers and fishermen over the last two centuries and now kept in the Smithsonian Institution.
The pygmy sperm whales had eaten 35 different species of cephalopod, and the dwarf sperm whales had consumed 13 species. A lone female pygmy sperm whale had a more varied diet, with two fish species — Sloane’s viperfish and Parin’s spinyfish— in her stomach. When she was left out of the analysis, the researchers found large overlap in diet between the two species.
They confirmed that overlap with analysis of the carbon and nitrogen isotopes in the whales’ muscle. Those isotopes reflect the food a creature has been eating, and they were also similar in the two sperm whale species.
“Overall, our results imply there is minimal niche partitioning between [the two] whales, thus shared food resources are likely not limited in offshore habitats of the mid-Atlantic region,” the researchers write.
The whales seem to have plenty of food for now, enough to share. But there is worry that that could change, particularly with climate change pushing some, but not all, species to move and upending established food webs. If that happens, the pygmy sperm whale will have a distinct advantage over its smaller brethren simply because of its larger bulk. Because the animals swallow their prey whole, the size of what a sperm whale can eat is dictated by the size of its esophagus. The pygmy sperm whale’s ability to eat larger prey could give it a leg up in the future, the researchers write.

We sat down with Richard Artz, environmental scientist at NOAA’s Air Resources Laboratory, to learn more about the new global assessment of air pollutants that fall to the earth in precipitation and in dry form. The assessment is available online in the journal Atmospheric Environment.
Today, NOAA and its partners released the first federal strategic plan to guide research and monitoring investments that will improve our understanding of ocean acidification, its potential impacts on marine species and ecosystems, and adaptation and mitigation strategies.
New NOAA research has revealed unprecedented changes in ocean carbon dioxide in the tropical Pacific Ocean over the last 14 years, influencing the role the oceans play in current and projected global warming and ocean acidification. Natural variability has dominated patterns in ocean CO2 in this region, but observations now show human activity contributes to increasing CO2 levels.
As our planet is warming, not only have Earth’s climate zones begun to shift – the pace of change is expected to accelerate, according to a new study led by the NOAA Cooperative Institute for Research in Environmental Sciences at the University of Colorado.
The largest harmful algae bloom in Lake Erie’s recorded history was likely caused by conditions that are expected to become more common in the future due to climate change.
Rain Garden, a new free iPhone app, guides users on how to create and install rain gardens that curtail runoff of pollutants, prevent erosion, and provide wildlife habitat.
Earth’s oceans, forests and other ecosystems continue to soak up about half the carbon dioxide emitted into the atmosphere by human activities, even as those emissions have increased, according to a study by University of Colorado and NOAA scientists published today in the journal Nature.
Visitors to Lake Huron this summer may have a unique opportunity to glimpse science in action. During July and September, scientists will crisscross Thunder Bay, Saginaw Bay, and the open waters of Lake Huron, collecting samples of sediment, water, mussels, microscopic organisms, and fish.
Oceanic and Atmospheric Research (OAR) - or "NOAA Research" - provides the research foundation for understanding the complex systems that support our planet. Working in partnership with other organizational units of the NOAA, a bureau of the Department of Commerce, NOAA Research enables better forecasts, earlier warnings for natural disasters, and a greater understanding of the Earth. Our role is to provide unbiased science to better manage the environment, nationally, and globally.

PreprintChemical composition of the graphitic black carbon fraction in riverine and marine sediments at sub-micron scales using carbon X-ray spectromicroscopy( 2005-12-01) Haberstroh, Paul R. ; Brandes, Jay A. ; Gelinas, Yves ; Dickens, Angela F. ; Wirick, Sue ; Cody, George D.The chemical composition of the graphitic black carbon (GBC) fraction of marine organic matter was explored in several marine and freshwater sedimentary environments along the west coast of North America and the Pacific Ocean. Analysis by carbon x-ray absorption near edge structure (C-XANES) spectroscopy and scanning transmission x-ray microscopy (STXM) show the GBC-fraction of Stillaguamish River surface sediments to be dominated by more highly-ordered and impure forms of graphite, together forming about 80% of the GBC, with a smaller percent of an aliphatic carbon component. Eel River Margin surface sediments had very little highly-ordered graphite, and were instead dominated by amorphous carbon and to a lesser extent, impure graphite. However, the GBC of surface sediments from the Washington State Slope and the Mexico Margin were composed almost solely of amorphous carbon. Pre-anthropogenic, highly-oxidized deep-sea sediments from the open Equatorial Pacific Ocean contained over half their GBC in different forms of graphite as well as highly-aliphatic carbon, low aromatic/highly-acidic aliphatic carbon, low aromatic/highly aliphatic carbon, and amorphous forms of carbon. Our results clearly show the impact of graphite and amorphous C phases in the BC fraction in modern riverine sediments and nearby marine shelf deposits. The pre-anthropogenic Equatorial Pacific GBC fraction is remarkable in the existence of highly-ordered graphite.


Sexy Fish – Grey Tilefish
Our Sexy Fish this week is the Grey Tilefish. They live in the deep cold waters along the continental shelf. Because they hide in underwater canyons, they weren’t discovered until 1879. Tilefish are colorful fish with yellow spots, big heads, and big eyes. The ones that live in the deepest water feed on crustaceans, which give tilefish a mild flavor that has been compared to lobster or scallops.


FSU professor of art, Carolyn Henne, has adapted marine scientist Niels Lindquist and commercial fisherman Clammerhead “David” Cessna’s invention of a biodegradable hardscape named Oyster Catcher™, to sculpt an oyster reef. Once in place, natural processes over several years will transform the Oyster Catcher™ sculpture into a vibrant, living oyster reef, providing shelter and foraging habitat for fishes, crabs and shorebirds, and a sustainable source of nutritious food for people.
Henne dreamed up Sea Stars with its constellations of life-sized synchronized swimmers and a larger-than-life octopus companion. Lindquist believes “Sea Stars speaks to the ‘coastal condition’ epitomized by the entanglement of human and natural communities, sustainable exploitation of nature and change.”
Sea Stars will spring to life late May 2021 in the Newport River near Beaufort, North Carolina (34.74105 N; 76.67202 W) on Sandbar Oyster Company’s (co-founded by Clammerhead and Lindquist) inter-tidal shellfish lease named “The Spa”. Sea Stars will be “framed” with a narrow oyster reef created with Oyster Catcher™ Tables.
To make a tax-deductible donation to support the Sea Stars project, send a check to the North Carolina Coastal Federation (3609 N.C. 24, Newport, NC 28570) with “Sea Stars” in the memo line, or scan the QR Code to go to the NCCF sponsored Sea Stars donation webpage.

France orders government to order end of dolphin-porpoise deaths
PARIS, France: Amidst the mass deaths of dolphins and porpoises in recent years, France's highest administrative body has ordered the government to better protect endangered whales, dolphins and porpoises, in an industrial fishing hub in the Atlantic Ocean.
The move was welcomed by conservationists, who have ben working to prevent some species in the zone from becoming extinct.
France's council of state gave government officials six months "to close areas of fishing in the Bay of Biscay for appropriate periods, in order to limit the number of deaths of common dolphins, bottlenose dolphins and harbor porpoises that are victims of accidental capture during fishing."
It also required them to compile a reliable estimate of the annual number of accidental catches.
According to government-affiliated scientists, some 10,000 dolphins and porpoises are killed every year in that maritime zone in western France, with one recent year recording 18,000 deaths. The fishing industry is widely blamed for the deaths.
It was noted that some species are now in a state of "unfavorable conservation," with the common dolphin and harbor porpoise in "serious danger of extinction" in the region.
"Of course, this move is a ray of hope for us, but it is bittersweet. So many dolphins are already dead, we see dead creatures washed up every day. I hope it is not too late. We have come so far. Even a few years ago in France, no one knew about these horrors," said Lamya Essemlali of Sea Shepherd France, as quoted by the Associated Press.
However, conservation groups stressed that dolphins in the fishing zone are already behaving in ways scientifically consistent with a dying population.
