The data described here is from near-shore shallow water Conductivity-Temperature-Depth (CTD) casts conducted in Aua Reef, American Samoa, by scientists of the Ecosystem Sciences Division (ESD) of the NOAA Pacific Islands Fisheries Science Center (PIFSC). The NOAA Fisheries, Ecosystem Sciences Division established 18 survey sites along the water quality gradient near land-based source pollution. This is part of a larger collection of datasets collected as part of the CRCP-funded project 'Linking watershed management activities to reef health in American Samoa' (project no.

This dataset contains the trajectory profile data from glider ru30 from one seasonal deployment (2021-02-26 to 2021-03-21) to investigate carbonate chemistry and monitor ocean acidification seasonally in the Mid-Atlantic Bight. The glider used for the automated observation includes an integrated deep rated version of the Ion Sensitive Field Effect Transistor (ISFET)-based pH sensor.

This dataset includes profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity, dissolved oxygen and other parameters measured during the R/V Oden SAS-Oden 2021 (SO21) cruise (EXPOCODE 77DN20210725) in the Arctic Ocean from 2021-07-25 to 2021-09-20. The SAS-Oden 2021 expedition (SO21) with icebreaker Oden1 (IB Oden) is the Swedish contribution to the international scientist-driven initiative ”Synoptic Arctic Survey” (SAS)2.

The ocean absorbs one quarter of the global CO2 emissions from human activity. The community-led Surface Ocean CO2 Atlas (www.socat.info) is key for the quantification of ocean CO2 uptake and its variation, now and in the future. SOCAT version 2023 has quality-controlled in situ surface ocean fCO2 (fugacity of CO2) measurements on ships, moorings, autonomous and drifting surface platforms for the global oceans and coastal seas from 1957 to 2023. The main synthesis and gridded products contain fCO2 values with an estimated accuracy of better than 5 μatm.

This dataset contains the nutrient results for an experiment that assessed the effects of elevated NH4 on corals disease susceptibility. Eleven Acropora cervicornis genotypes were selected to conduct a full factorial tank. Replicate coral fragments (n=24 per genotype) were obtained in July-August 2020 from three South Florida coral nurseries and allowed to recover in tanks in the University of Miami and NOAA’s Experimental Reef Lab (ERL). After recovery from handling, the fragments were evenly allocated to one of eight independent tanks at ERL.

This study examined the impact of long-term shifts in water temperature and salinity as a result of climate change on the biomasses of important fisheries species within oyster sanctuary sites in the Choptank and Little Choptank river complex in Chesapeake Bay using an Ecopath with Ecosim food web model. The model was used to evaluate changes in the oyster reef food web, with particular emphasis on impacts to striped bass (Morone saxatilis), blue crab (Callinectes sapidus), and Eastern oysters (Crassostrea virginica).

NOAA Great Lakes Environmental Research Laboratory (GLERL) samples and studies the ecosystem of the lower food web of the Laurentian Great Lakes. This collection contains continuous, underwater ultraviolet (UV), PAR and temperature profiles at 5 stations during the open water season in Lake Huron in 2022. The measurements were collected using a Biospherical Instruments Inc. PUV-2500 submersible, multichannel, profiling, ultraviolet radiometer and PUV2510 reference radiometer attached to the ship during profile collection.

This dataset includes hydrographic and chemical data collected from discrete sample and profile observations during the R/V Sikuliaq cruise SKQ202115s (EXPOCODE 33BI20211108) in the Bering and Chukchi Sea along transect lines in the Distributed Biological Observatory (DBO) from 2021-11-08 to 2021-11-16. These data include WATER CTD TEMPERATURE, CTD SALINITY, DISSOLVED INORGANIC CARBON (DIC), TOTAL ALKALINITY (TA), CTD Dissolved OXYGEN, and nutrients (Nitrate, Nitrite, Phosphate, Silicate, and Ammonium).

This dataset contains physical oceanography and fish abundance collected by CTD, surface trawl, and tagged fish from the research vessel Hokko Maru in the Central Bering Sea. This dataset is U.S. State Department MSR RATS U2022-001 as part of the World Data Service for Oceanography. Data are in XLSX format, cruise report is in DOC.

This dataset consists of carbonate chemistry discrete profile data collected on two of the Northeast US Coast Shelf LTER cruises, EN617 and EN627 summer 2018 and winter 2019. The dataset includes in situ temperature, salinity, and dissolved oxygen as measured from a CTD, and also includes discrete samples for dissolved inorganic carbon and total alkalinity.
