title: Nitrogen compound-specific isotope values of amino acids for each gelatinous zooplankton sample and the sample's estimated trophic position from R/V Sally Ride and R/V Roger Revelle cruises in the southern California Current Ecosystem from 2020-2023

description: We estimated the trophic positions of abundant gelatinous zooplankton (chaetognaths, cnidarians, ctenophores, molluscs, and pelagic tunicates) in the southern California Current Ecosystem using stable carbon and nitrogen isotope analysis. Gelatinous zooplankton were collected on four research cruises on the R/V Sally Ride and R/V Roger Revelle between 2020 and 2023 and from 0 to 3,000 meters depth using a 10-square-meter Multiple Opening/Closing Net and Environmental Sensing System (MOCNESS). 561 samples of gelatinous zooplankton from thirteen taxonomic groups were chosen for bulk tissue stable isotope analysis. An additional twenty samples from seven gelatinous genera were chosen for nitrogen compound-specific isotope analysis of amino acids because they were abundant across our region and represented a range of hypothesized feeding guilds and depth habitats (0 – 1,025 meters). Gelatinous zooplankton were briefly thawed to remove visible gut contents using forceps and a scalpel. Samples were then lyophilized and homogenized. To ensure sufficient sample mass for stable isotope analysis, samples often contained multiple individuals from the same net, taxonomic group, and size class. The number of individuals per sample was typically fewer than 100, with a larger number of individuals pooled for some samples of Pantachogon spp. and Hormiphora spp. Samples were processed for nitrogen compound-specific isotope analysis at the Laboratory for Marine Organic Isotope Geochemistry at the University of Miami. This dataset includes the nitrogen compound-specific isotope values of amino acids for each gelatinous zooplankton sample and the sample's estimated trophic position.

title: Temperature, pH, DO, and salinity data from Mumford Cove, Connecticut, USA from 2015-2025

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.

title: OOI Coastal Pioneer New England Shelf Array CTD and Discrete Water Sampling Data from Mooring Overturning Cruises at the New England Continental Shelf from 2013-2022 (OOI Cruise Data Project)

description: The hydrographic sampling performed by OOI-CGSN (the Ocean Observatories Initiative - Coastal and Global Scale Nodes) as part of each Array turn represents a significant collection of valuable physical, chemical, and biological information. In addition to the CTD, collected hydrographic data include discrete oxygen, salinity, nutrient (nitrate, nitrite, silicate, phosphate, ammonium), chlorophyll, and carbon system measurements. These data serve several important functions. First, they are necessary for the calibration and evaluation of the moored instrumentation at each Array. Furthermore, the annual (Global) or biannual (Coastal) collection of data at the same locations provides a unique time series of a large set of water properties following established community standards and methods, independent of its association with the OOI moorings.


The analyses of collected water samples for the parameters listed above are performed by a number of outside labs on behalf of OOI-CGSN. Consequently, the water sampling data for a given cruise is distributed among a number of different files. The Discrete Sampling Summary integrates the related CTD, metadata, and discrete water sample data into a single file. Additionally, it synthesizes qualitative and quantitative information about the quality of a measurement into data quality flags for each associated parameter which follow WOCE-standards.


The final product is the Discrete Sampling Summary spreadsheet which contains the metadata, CTD data and discrete water sample data into a single spreadsheet with data quality flags.


The Coastal Pioneer New England Shelf (NES) Array was located off the coast of New England, about 75 nautical miles south of Martha’s Vineyard from 2013 to 2022. 


The Continental Shelf-Slope area in this region is highly productive. It serves as a dynamic intersection where ocean currents meet in weather-like “fronts,” and where nutrients, pollutants, and other properties are exchanged between the coast and the deep ocean. Data from the inshore, shelf area helps to examine exchanges between the shelf and slope and the shelf ecosystem, as well as to provide broader insight into air-sea gas exchange, including carbon dioxide absorption.The seven-site mooring array spans along- and across-shelf distances of 9 km and 47 kilometers (km). Mooring sites are separated from each other by distances of 9.2 km to 17.5 km.

title: Small and large particle concentrations of total carbon, total nitrogen, and inorganic carbon, and particulate thorium-234 and RAP234 from large volume pump profiles collected on R/V Endeavor cruise EN665 in the Gulf of Maine in April 2021

description: Sample collection took place at two primary stations within the Gulf of Maine's Wilkinson and Jordan basins from the R/V Endeavor in April 2021. McLane pumps were deployed at eight depths throughout the water column from near the sea surface (~14 meters) to near the seafloor (~250 meters). The first deployment occurred in the Wilkinson Basin and the second occurred in the Jordan Basin. Small (1-51 micrometer (µm)) and large particle (&gt;51 µm) concentrations of total carbon, total nitrogen, and inorganic carbon (PC, PN, and PIC, respectively) are presented, along with small particle isotopic compositions (13C, 15N) of these phases, particulate thorium-234, and RAP234 (a resuspension proxy associated with particulate thorium-234). Depth profiles demonstrate typical particulate carbon shapes. The PIC demonstrates a peak near the seafloor, indicating the potential presence of a nepheloid layer. This feature does not appear in the PC data. The isotopic composition of the PIC demonstrates uniquely negative values throughout the water column. Small particle thorium-234 activities were consistently larger than the large particle activities at all depths and small particle RAP234 activities indicate possible resuspension in the bottom ~50 m of the water column. These data were collected by Drs. Adam Subhas (WHOI) and Erin Black (UR). Data processing and preparation were completed by Dr. Subhas, Dr. Black, and Karine Holmes (UR).

title: Discrete sample measurements of dissolved oxygen, dissolved inorganic carbon, and total alkalinity from the Seven Mile Island Innovation Laboratory (SMIIL) from Aug 2022 to Jun 2024

description: This dataset contains discrete sample measurements of dissolved oxygen, dissolved inorganic carbon, and total alkalinity collected from 2022 through 2024 from a tidal salt marsh in New Jersey, USA. The marsh is located landward of Seven Mile Island, a populated barrier island in Cape May County, New Jersey, and is a part of the Seven Mile Island Innovation Laboratory (SMIIL), a research initiative focused on advancing dredging and marsh restoration practices. Samples in this dataset were collected as part of a collaboration between Boston College and the U.S. Army Corps of Engineers Engineer Research and Development Center. This project encompassed multi-year biogeochemical sensor deployments within the main tidal salt marsh channel and salt ponds on the marsh platform, as well as targeted deployments to monitor beneficial use dredged sediment placements. Beginning in August-September 2022, discrete samples for dissolved oxygen, total alkalinity, and dissolved inorganic carbon were collected at the start and end of each sensor deployment for additional sensor calibration and validation. We provide the discrete sample measurements alongside collected salinity and temperature sensor data from the locations where sensors were deployed.

title: Dissolved organic matter and nutrient data from water samples collected in Dec 2020 from six sponge species at two coral reef sites in the Florida Keys

description: Sponges are sessile filter-feeders that can process vast amounts of water and are known to influence the chemistry of the surrounding seawater. There has been limited work however to understand the extent to which sponges alter dissolved organic matter (DOM), yet in areas where sponges are abundant, sponges may contribute significantly to the reef seawater profile of DOM. Incurrent and excurrent seawater samples were collected for each of the six sponge species and processed for: inorganic nutrients, fluorescent dissolved organic matter (fDOM), untargeted and targeted metabolomics, and particulate matter by flow cytometry. This dataset also includes collection metadata for these samples. Sponges were sampled from two coral reef sites in the Florida Keys (Florida, USA): Looe Key reef and Wonderland reef in the southern Florida Keys. We found higher similarity of the DOM profile from untargeted metabolomics between sponge excurrent sponge samples; however, each species also had unique characteristics. These results provide additional support for the large impact that sponges have in the dissolved nutrient profile on coral reefs and provide support for a species-specific impact, with some species altering the DOM profile, fDOM profile, and/or inorganic nutrients to a greater extent than other species. These results have implications for better understanding the influence of the sponge community on coral reef nutrient dynamics.

title: Water column dissolved organic carbon (DOC) reactivity along the York River Estuary (YRE) from surface samples collected in October 2018 and February, April, and July 2019

description: Data were collected to evaluate spatiotemporal variations in, and environmental controls on, water column dissolved organic carbon (DOC) reactivity along the York River Estuary (YRE), a temperate microtidal sub-estuary of the Chesapeake Bay in southeastern Virginia. Data were also collected as part of the larger, NSF-funded project (NSF BIO-OCE #1737258) entitled &quot;Alteration of carbon fluxes by intense phytoplankton blooms in a micro tidal estuary.&quot; Surface water column samples were collected in October 2018 and February, April, and July 2019 from three locations along the YRE estuarine salinity gradient. Filtered water was inoculated and incubated in the dark at in situ York River water temperatures, and sub-sampled at the onset of the experiment (T0), one day following onset (T1), and weekly for 28 days thereafter (T7, T14, T21, T28). Samples were analyzed for DOC concentrations.

title: Iodine incubation data collected from RRS Discovery cruise AMT-30 during February 23 - March 27th, 2023

description: This dataset includes the incubation data described in the following study abstract (see &quot;Related Datasets&quot; for more data from this study):

The oxidized iodine species, iodate, is abundant in well-oxygenated marine waters and can be tracked in sediments to reconstruct ancient oxygen availability. Despite known modern marine spatial variations in both iodate and reduced iodide, the rates, pathways, and locations of iodate formation remain poorly understood for temporal gradients across Earth history. To quantify rates and pathways of iodate formation across an ocean basin, we performed ship-board tracer experiments in euphotic waters with known gradients in iodine speciation on an Atlantic Meridional Transect (45°S and 37°N). We performed incubations at depths corresponding to 7% and 1% of ambient surface light levels, thus tracking the boundaries of the deep chlorophyl maximum (DCM), from 11 stations along the transect. All incubations were spiked with a 129I (t1/2 ~15.7 My) tracer and mimicked ambient conditions. We observed iodate production via multiple pathways. The most common observation was a lack of significant iodate production, with iodate production limited to 7 of the 22 locations and nearly exclusively observed at the DCM and outside the nitrogen and iron limited South Atlantic Gyre. Iodate formation from direct iodide oxidation is inferred in only two locations based on increases in iodate 129I/127I ratios. At the other locations, decreases in iodate 129I/127I ratios imply that rapid reactions with and overturning of alternative natural iodine pools, likely iodine intermediates, are an important factor for iodate production. Our work emphasizes that the rates and pathways of iodate production are spatially heterogenous in the Atlantic Ocean. Future work is needed to determine the drivers, temporal variations, and trends within global ocean basins.
