title: Meteorological data from the Tudor Hill Marine Atmospheric Observatory, Bermuda in 2017, 2019, 2020, 2021 and 2022

description: The BIOS Tudor Hill Marine Atmospheric Observatory (THMAO) has been supported by the NSF Chemical Oceanography and Atmospheric Chemistry Programs following a major refit in 2003. Since that time it has provided a unique research facility for the scientific community. The specific objectives are:

1) To operate and maintain a state-of-the-art marine atmospheric sampling and observing facility at Tudor Hill, Bermuda, available for use by the wider U.S. and international research community;
2) To continue the collection of continuous meteorological data and weekly bulk-aerosol and rainwater samples, which will be archived at BIOS and made freely available to other researchers;
3) To collect additional atmospheric samples and data for other investigators (primarily in longer-term time-series programs), and to provide for the use of the facility in person by other investigators (primarily in shorter-term intensive programs).

title: Echosounder data (38kHz) collected along the slope between Faial and Pico Island Azores in November and December of 2021

description: We collected 38 kHz scientific grade echosounding along the slope between Faial and Pico Island Azores. These data span night and day time periods and were aimed at measuring the diel vertical migration of the deep scattering layer in the area. The transducer was mounted near the transom of a boat and was submerged 0.5 meters below the surface.

title: Number and size of eggs found in five different branches from a single Antillogorgia americana from a study site in the San Blas Islands, Panama from July 1990 to August 1991

description: The reproductive biology of the branching octocoral Antillogorgia americana was studied at a site on the Caribbean coast of Panama in 1990-1991. Eleven colonies were tagged and monthly samples were collected over a 14-month period. Colonies were gonochoric and the samples included 6 females and 4 females. Ten polyps were examined from each sample and the number and size of gonads were determined.  An additional 4 branches were sampled from a female colony in January 1991 and fecundity was determined relative to the branch, position of branchlet on the branch, and position of the polyp on the branchlet. The lack of synchrony among colonies on the scale of months may reflect less need for all colonies to spawn in a single event among abundant species that release large numbers of gametes. Such a strategy also spreads the risk of reproductive failure due to environmental conditions during any single month. Multiple spawning episodes can also drive reproductive isolation of populations and may reflect the presence of cryptic species within the taxon. Studies of reproductive timing can be an important adjunct in identifying variation in life history strategies as well as assessing the validity of species boundaries. 

This dataset describes branch variation, including the number and size of eggs found in five different branches from a single Antillogorgia americana. Ten polyps were sampled from four branchlets and two positions on the branchlets of each branch.

Understanding population dynamics is a long-standing objective of ecology, but the need for progress in this area has become urgent. For coral reefs, achieving this objective is impeded by a lack of information on settlement versus post-settlement events in determining recruitment and population size. Declines in coral abundance are often inferred to be associated with reduced densities of recruits, which could arise from mechanisms occurring at larval settlement, or throughout post-settlement stages. This study uses annual measurements from 2008 to 2021 of coral cover, the density of coral settlers (S), the density of small corals (SC), and environmental conditions, to evaluate the roles of settlement versus post-settlement events in determining rates of coral recruitment and changes in coral cover at Moorea, French Polynesia. Coral cover, S, SC, and the SC:S ratio (a proxy for post-settlement success), and environmental conditions, were used in generalized additive models (GAMs) to show that: (a) coral cover was more strongly related to SC and SC:S than S, and (b) SC:S was highest when preceded by cool seawater, low concentrations of Chlorophyll a, and low flow speeds, and S showed evidence of declining with elevated temperature. Together, these results suggest that changes in coral cover in Moorea are more strongly influenced by post-settlement events than settlement. The key to understanding coral community resilience may lie in elucidating the factors attenuating the bottleneck between settlers and small corals.

title: Results from bulk cyclic AMP (cAMP) assays conducted to investigate the role of soluble adenylyl cyclase (sAC) in sperm from the gonochoric, broadcast spawning coral Astrangia poculata

description: Most stony corals liberate their gametes into the water column via broadcast spawning, where fertilization hinges upon the activation of directional sperm motility. Sperm from gonochoric and hermaphroditic corals display distinct morphological and molecular phenotypes, yet it is unknown whether the signallng pathways controlling sperm motility are also distinct between these sexual systems.

title: Synthesis Product for Ocean Time Series (SPOTS)

description: The presented time-series data synthesis pilot product includes data from 12 fixed ship-based time-series programs. The related stations represent unique marine environments within the Atlantic Ocean, Pacific Ocean, Mediterranean Sea, Nordic Seas, and Caribbean Sea. The focus of the pilot has been placed on biogeochemical essential ocean variables: dissolved oxygen, dissolved inorganic nutrients, inorganic carbon (pH, total alkalinity, dissolved inorganic carbon, and partial pressure of CO2), particulate matter, and dissolved organic carbon. The time-series used include a variety of temporal resolutions (monthly, seasonal, or irregular), time ranges (10 to 36 years), and bottom depths (80 to 6000 meters), with the oldest samples dating back to 1983 and the most recent one corresponding to 2021. Besides having been harmonized into the same format (semantics, ancillary data, units), the data were subjected to a qualitative assessment in which the applied methods were evaluated and categorized. Additional data-quality descriptors include precision and accuracy estimates. This data product pilot facilitates a variety of applications that benefit from the collective value of biogeochemical time-series observations and forms the basis for a sustained time-series living data product, complementing relevant products for the global interior ocean carbon data (GLobal Ocean Data Analysis Project), global surface ocean carbon data (Surface Ocean CO2 Atlas; SOCAT), and global interior and surface methane and nitrous oxide data (MarinE MethanE and NiTrous Oxide product).

description: Seawater samples were collected from Niskin bottles with acid-washed syringes to avoid ammonium contamination from air and ship fumes. Samples were kept frozen (-20 ºC) until analysis. Nitrite was measured at the nanomolar level following Bendschneider and Robinson (1952) method, using a flow-injection system coupled to a 2m Liquid Waveguide Capillary Cell to read the color. Low nutrient seawater was used for working standards preparation, blanks and carrier. The absorbance-concentration relationship was linear up to at least 200 nM nitrite, with a method detection limit of 0.7 nM and an error of 1.5% at 50-100 nM and 2% at 150 nM.
