title: Stable carbon isotope data for thirteen individual amino acids from twelve species of eukaryotic microalgae and four species of eukaryotic microalgae

description: Using controlled cultures, this project characterized the amino acid carbon isotope fingerprints — a multivariate metric of amino acid carbon isotope values — of twelve different species of eukayrotic microalgae from four major Classes of eukaryotic microalgae: diatoms, dinoflagellates, raphidophytes, and prasinophytes (three species per Class). Phytoplankton cultures were generated from established laboratory culture lines in the URI microalgal libraries and the National Center for Marine Algae and Microbiota (NCMA; formerly CCMP).

This dataset includes stable carbon isotope data for thirteen individual amino acids from all twelve species of eukaryotic microalgae grown at 20° Celsius (C) and four species of eukaryotic microalgae (one from each of the four Classes) raised at 15°C, 20°C, and 25°C. Cultures were grown in triplicate for each species and temperature treatment under highly constrained growth conditions. These amino acid carbon isotope data were used to identify primary producers at the base of food webs supporting consumers in two contrasting systems from published literature: 1) penguins feeding in a diatom-based food web (McMahon et al. 2015 Ecology and Evolution 5:1278–1290) and 2) mixotrophic corals receiving amino acids directly from autotrophic endosymbiotic dinoflagellates and indirectly from water column diatoms, prasinophytes, and cyanobacteria, likely via heterotrophic feeding on zooplankton (Fox et al. 2019 Functional Ecology 33:2203-2214). The increased taxonomic specificity of CSIA-AA (Compound-Specific Isotope Analysis of Amino Acids) fingerprints developed here will greatly improve future efforts to reconstruct the contribution of diverse eukaryotic microalgae to the sources and cycling of organic matter in food web dynamics and biogeochemical cycling studies.

title: Dissolved inorganic carbon and total alkalinity fluxes from sediment incubation experiments during four R/V Pelican cruises to the Louisiana shelf in 2017 and 2018

description: These data include the measurements of dissolved inorganic carbon (DIC) and total alkalinity (TA) fluxes from sediment incubation experiments at several sites on the Louisiana shelf. Data were collected during four cruises in 2017 and 2018. Cruises were conducted aboard the R/V Pelican in April (PE17-18), July (PE18-02), and September-October (PE18-11) of 2017 and January of 2018 (PE18-19). The study domain included the Louisiana and Texas continental shelf from the Mississippi River Bird's Foot delta to south of Galveston Bay. The objective of this work was to quantify how hurricanes and tropical storms affect metabolic rates and the concentrations of oxygen and DIC/pH. These data assess the sediment metabolism response before and after Hurricane Harvey and were collected by Dr. John Lehrter of the University of South Alabama.

title: High throughput growth screening of the marine bacterium Ruegeria pomeroyi DSS-3 knockout mutants on 70 environmentally relevant marine substrates done in 2021.

description: An array of transporter knockout mutants of the marine bacterium Ruegeria pomeroyi DSS-3 mutants were screened for growth on 70 environmentally relevant marine substrates. The array contains 156 isolated knockout mutants of putative transporter genes as well as positive and negative growth controls and is distributed across two 96-well plates. Actively growing cultures were inoculated into freshly prepared 96 well plates containing minimal medium with a single substrates as sole carbon source. Plates were grown for 24 to 96 hours with growth monitored by optical density at 600 nm. Mutants that demonstrated growth defects on a given substrate, relative to typical growth on that substrate were selected for higher resolution follow up testing.

title: Winter growth and lipid accumulation in juvenile Black sea bass exposed to varying food and temperature conditions during lab experiments conducted from September 2021 to April 2022 at UConn Avery Point

description: The northern stock of Black sea bass (BSB, Centropristis striata) has greatly expanded over the past decade, potentially due to warming Northwest Atlantic shelf waters affecting overwintering especially in juveniles. To gather better empirical data we quantified winter growth and lipid accumulation in BSB juveniles from Long Island Sound using two complementing experiments. The data from Experiment 1 are presented here.

Experiment 1 measured individual length growth (GR), weight-specific growth (SGR), growth efficiency, and lipid content at constant food and three static temperatures: 6°, 12°, and 19° Celsius (C). Average GR (SGR) decreased from 0.24 millimeters per day (mm d-1) at 19°C (0.89% d-1) to 0.15 mm d-1 at 12°C (0.54% d-1) to 0.04 mm d-1 at 6°C (0.17% d-1). Even at the coldest temperature, most juveniles sustained positive GRs and SGRs; hence, the species’ true thermal growth minimum may be below 6°C. However, lipid accumulation was greatest at 12°C, which is close to what overwintering juveniles likely encounter offshore.

The data from Experiment 2 are presented in a related dataset (https://www.bco-dmo.org/dataset/898012). In both experiments, juveniles disproportionally accumulated lipid over lean mass, with lipid proportions tripling in Exp2 from 4% at 65 mm to 12% at 120 mm.

title: Temperature-dependence of juvenile Black sea bass growth and lipid accumulation determined through lab experiments conducted from September 2021 to February 2022 at UConn Avery Point

description: The northern stock of Black sea bass (BSB, Centropristis striata) has greatly expanded over the past decade, potentially due to warming Northwest Atlantic shelf waters affecting overwintering especially in juveniles. To gather better empirical data we quantified winter growth and lipid accumulation in BSB juveniles from Long Island Sound using two complementing experiments. The data from Experiment 2 are presented here.

The data from Experiment 1 are presented in a related dataset (https://www.bco-dmo.org/dataset/897895). Experiment 2 measured the same traits as Experiment 1 but exposed juveniles to a simulated thermal overwinter profile (October - March) with seasonally varying food rations. Monthly individual length growth (GR) and weight-specific growth (SGR) responded in the direction of seasonal food level changes, showing reduced growth in December-February in a 'Winter dip' treatment, but compensatory growth in a 'Winter pulse' treatment. A 6-month consumption average of 1.7% feeding-1 ('Winter pulse') elicited a mean GR of 0.15 millimeters per day (mm d-1) and SGR of 0.55% d-1, whereas juveniles consuming on average 3.8% per feeding ('Winter dip') had significantly faster GR (0.20 mm d-1) and SGR (0.71% d-1). Growth efficiencies ranged between 15-30% and were inversely related to food consumption.

In both experiments, juveniles disproportionally accumulated lipid over lean mass, with lipid proportions tripling in Exp2 from 4% at 65 mm to 12% at 120 mm.

title: A spatially and vertically resolved global grid of dissolved barium concentrations in seawater determined using Gaussian Process Regression machine learning

description: We present a spatially and vertically resolved global grid of dissolved barium concentrations ([Ba]) in seawater determined using Gaussian Process Regression machine learning. This model was trained using 4,345 quality-controlled GEOTRACES data from the Arctic, Atlantic, Pacific, and Southern Oceans. Model output was validated by assessing the accuracy of [Ba] simulations in the Indian Ocean, noting that none of the Indian Ocean data were seen by the model during training. We identify a model that can accurate predict [Ba] in the Indian Ocean using seven features: depth, temperature, salinity, as well as dissolved dioxygen, phosphate, nitrate, and silicate concentrations. This model achieves a mean absolute percentage error of 6.0 %, which we assume represents the generalization error. This model was used to simulate [Ba] on a global basis using predictor data from the World Ocean Atlas 2018. The global model of [Ba] is on a 1°x 1° grid with 102 depth levels from 0 to 5,500 m. The dissolved [Ba] output was then used to simulate dissolved Ba* (barium-star), which is the difference between 'observed' and [Ba] predicted from co-located [Si]. Lastly, [Ba] data were combined with temperature, salinity, and pressure data from the World Ocean Atlas to calculate the saturation state of seawater with respect to barite. The model reveals that the volume-weighted mean oceanic [Ba] and and saturation state are 89 nmol/kg and 0.82, respectively. These results imply that the total marine Ba inventory is 122(±7) ×10¹² mol and that the ocean below 1,000 m is at barite equilibrium.

title: Temperature, pH, DO, and salinity data from Mumford Cove, Connecticut, USA from 2015-2022

description: Despite their importance for research and environmental protection, there's still a shortage of high quality and high-resolution temperature, pH, and oxygen data particularly in shallow coastal habitats. We monitor five important environmental parameters (i.e., depth, temperature, salinity, pH, and dissolved oxygen) at 30 minute intervals in Mumford Cove, CT (41 degrees 19'25&quot;N, 72 degrees 01'07&quot;W), a small (2 km N-S × 0.5 km E-W), shallow (1-5 meters), cone-shaped embayment opening to northeastern Long Island Sound, with protected marsh habitat along its western side, marsh and beach habitat along its eastern side, and an extensive seagrass (Zostera marina) cover. Continuous monitoring is achieved by swapping identical and recalibrated probes (Eureka Manta Sub2) every 3-5 weeks.
