Time series of zooplankton abundance in the Florida Keys, collected by the South Florida Program (NOAA/AOML) and the Marine Biodiversity Observation Network (MBON), Time series of zooplankton abundance of the South Florida Program / Sanctuaries Marine Biodiversity Observation Network programs

Keywords: Occurrence
Temporal coverage: 2015/2020, 2015/2017

Sampling is carried out bi-monthly on the R/V Walton Smith (University of Miami) as part of the South Florida Program (NOAA Atlantic Oceanographic and Meteorological Laboratory/ AOML) and the Marine Biodiversity Observation Network (MBON). Samples are collected at three stations: Molasses Reef (25.051638 N, 280.22858 W), Looe Key (24.323028 N, 281.248068 W), and Western Sambo (24.286048 N, 281.428898 W). At each station, horizontal hauls (surface water) are performed with 64, 200, and 500 mm mesh size Bongo plankton nets. Each net tow is carried out for 5 min at 1 knot. The three size classes are split using a Folsom plankton splitter and preserved with 15 % formalin for morphological analysis. Morphological identification follow the protocols of the International Council for the Exploration of the Sea (ICES) (Roger et al. 2000) targeting a minimum count of 200 animals per sample. For the 64 and 200 mm net tows, a 5–10 mL aliquot is subsampled after resuspension of 300 ml of the original zooplankton sample using a Stempel pipette. Zooplankton are then identified and counted using a microscope. Zooplankton are identified to the lowest taxonomic level possible. Zooplankton abundances (density; individuals m-3) are calculated by dividing animal counts by the product of net mouth area, tow speed, and tow duration (i.e., volume of water filtered by the net). Abundances of gastropods, the copepod order Harpacticoida, and the genera Paracalanus and Oithona are converted to biomass after Kelble et al. (2010).

Abstract:
In 1992 Oceanic Society began a study aimed at documenting the abundance, distribution, and behavioral ecology of bottlenose dolphins (<i>Tursiops truncatus</i>) in Belize. Our study site is Turneffe Atoll, a non-volcanic carribbean atoll ~40km east of Belize City with more than 200 mangrove cayes and surrounded by fringing coral reef. The atoll encloses a brackish lagoon whose shallow waters are the home to a population of bottlenose dolphins. To date more than a 175 dolphins have been identified in this region through photo-identification methods on surveys and follows. Studies on their abundance and distribution, habitat use, side-fidelity, and social affiliations have been conducted over the years since our work began.

From 1997 to 2001 researchers at OS conducted a study of the population of bottlenose dolphins located at the Drowned Cayes 8 km off the coast of Belize City. The close proximity of these regions suggested the possibility of overlap, yet only 3 were matched to both sites spurring more questions about the home ranges of dolphin populations in Belize. All research is conducted from small boats inside the atoll.

Purpose:
Photo-identification methods are used to track sightings of individuals who are recognizable through dorsal fin scarring. Some of our current research goals include the study of social and acoustic behavior in the dolphin population in this atoll conducted from small boats Of particular interest is the subset of the population classified as residents who demonstrate a side fidelity of nearly 20 years.
Located at the southernmost tip of Blackbird Caye researchers and partners of OS engage in scientific research on various aspects of the ecology and biodiversity of this complex and productive habitat. Some research has included the study of abundance and distribution of American crocodiles (<i>Crocdylus acutus</i>), sea turtles presence and nesting sites, and monitoring coral reef health. Antillean manatees (<i>Trichechus manatus manatus</i>) are also encountered in certain regions of Turneffe Atoll. Oceanic Society is partnered with researchers who conduct boat and aerial surveys for manatees.
Much remains to be understood cetacean abundance and distribution in this region as other cetaceans including Short-finned Pilot whales (<i>Globicephala marcorhyncus</i>) and  Atlantic-spotted dolphins (<i>Stenella frontalis</i>) are occasionally sighted beyond just at the bounds of Turneffe Atoll.

Abstract:
In fall 1991, Southeast Alaska, Cook Inlet, and Bristol Bay, were surveyed for harbor porpoise (<i>Phocoena phocoena</i>) from the NOAA John N. Cobb using line transect methodology.  The shipboard platform was 28.36 m (93 ft) in length with a bridge height of 4.27 m (14 ft). To obtain data on seasonal movements of porpoise, a limited number of transects were made in areas of known porpoise concentrations. When a sighting was made, the following variables were recorded: time, angle, number of reticles to the sighting, radar distance (nm) to the shoreline at the same angle of the sighting, the species, the count of the porpoise seen (best, high, and low), and the animal(s) direction of travel. Search effort was recoded by noting the time and location of the ship at the beginning and end of each transect.

Purpose:
Although harbor porpoises, <i>Phocoena phocoena</i>, are known to occur throughout Alaska waters, few estimates of abundance exist. In 1991, the National Marine Mammal Laboratory initiated a 3 year study on Alaska harbor porpoises. The objectives of this program were to: 
1) Obtain minimum population estimates in coastal waters using line transect methodology with a coefficient of variation for density estimates of less than 30% for each survey area, and 
2) Establish a baseline for detecting changes in abundance through time, for analysis of trends. 
The ability of the observers to sight porpoise was sensitive to environmental conditions. As expected, when conditions deteriorated the number of porpoises observed declined.

USGS Alaska Science Center Polar Bear Maternal Dens

Keywords: Observation, Occurrence
Temporal coverage: 1910/2018

This data reports on the approximate locations and methods of discovery of 530 polar bear (Ursus maritimus) maternal dens observed in the Beaufort and Chukchi seas and neighboring areas between 1910 and 2018, and archived partly by the U.S. Geological Survey, Alaska Science Center, and partly by the U.S. Fish and Wildlife Service, Marine Mammals Management, in Anchorage, Alaska. Data fields include a unique and permanent USGS identifier for each record, the year when the adult would have been expected to depart the den with young, an index of whether the maternal den was confirmed or probable, coordinates of the den, substrate that each den occurred on, the agency source of each record, method of discovery of each den, method used to determine the position of each den, and estimated position uncertainty. Data were collected through standardized VHF aircraft surveys and satellite radio telemetry, field research activities in polar bear habitat, and anecdotal reports from other government agencies, coastal residents, and industry personnel. The polar bear maternal den records presented here supersede an earlier version of these data (Durner and others, 2010)

Keywords: Phytoplankton, Metadata, Mediterranean Sea
Temporal coverage: 1934/1936

A study of the plankton in the Suez Canal could throw some light from the explanatory point of view,  on the distribution of the planktonic forms of the two different water bodies of  the Mediterranean and Red Sea. From the fisheries point of view, the plankton study is indispensable to seek out the relation between the abundance and movement of fishes and the fluctuations in the plankton; both in quantity and quality at different times, places and depths.
Dynamics of a coral reef community, Taiwan (2003 -2014)

Keywords: Occurrence, Observation
Temporal coverage: 2003/2014

Recurrent disturbances can have a critical effect on the structure and function of coral reef communities. In this study, long-term changes were examined in the hard coral community at Wanlitung, in southern Taiwan, between 1985 and 2010. In this 26 year interval, the reef has experienced repeated disturbances that include six typhoons and two coral-bleaching events. The frequency of disturbance has meant that species susceptible to disturbance, such as those in the genus Acropora and Montipora have almost disappeared from the reef. Indeed, almost all hard coral species have declined in abundance, with the result that total hard coral cover in 2010 (17.7%) was less than half what it was in 1985 (47.5%). In addition, macro-algal cover has increased from 11.3% in 2003 to 28.5% in 2010. The frequency of disturbance combined with possible chronic influence of a growing human population mean that a diverse reef assemblage is unlikely to persist on this reef into the future

Abstract:The first of three installations of in-stream tidal power infrastructure in the Minas Passage of the inner Bay of Fundy was deployed in November 2009. Little is known about the impact of turbine operation on the survival and behaviour of fishes moving through the Passage. To address the potential for fish-turbine interactions near the deployed OpenHydro turbine, we are using animal tracking technology developed by Vemco of Halifax, Nova Scotia, to track fish movement, behaviour and environmental preferences over a scale of kilometres. This project will provide real in-situ measurements of the direction, depth and velocity of tagged fishes moving through the Passage. Three species of concern will be tagged during 2010: Atlantic sturgeon, striped bass and American eels. Fishes tagged with acoustic transmitting tags will broadcast unique signals that will be archived by an array of acoustic hydrophone receivers in the Minas Passage. A dense array of receivers located at the OpenHydro turbine site will provide fine scale information on movements and behaviour of fish in relation to an operating tidal turbine. In addition a line of receivers spanning the Passage, placed in co-operation with OTN and Acadia University, will provide information on the spatial and temporal distribution and movement of fish in the Passage. To enhance the assessment of the risk to fishes of direct contact with the turbine, in situ data will be used to refine mathematical hydrodynamic models that predict how objects like fish move in the Passage and potentially interact with turbine infrastructure. This information will be valuable in identifying mitigation measures that may be taken to lessen any negative effects of in-stream turbine infrastructure on fish behaviour and survival.
