This dataset contains water temperature, salinity, marine chemistry, and other data collected by SBE 911 plus conductivity-temperature-depth (CTD) and Niskin bottles from R/V Mirai, cruise MR20-05C, in the Arctic Ocean, Bering Sea, and North Pacific Ocean. Data units are specified in corresponding "Format_Information.txt" files. This dataset is U.S. State Department MSR RATS U2020-004. Data are in csv, xls, text, and image formats. Reports are in PDF.

This data package includes the source imagery of a benthic cover analysis for surveys performed in 2020 by the NOAA Ecosystem Sciences Division (ESD) in Vatia, American Samoa. The imagery described here was collected during belt transect surveys of coral demography by the ESD according to protocols established by the NOAA National Coral Reef Monitoring Program (NCRMP).

This dataset is a hydrographic and atmospheric survey collected by sensors mounted on the Uncrewed Surface Vehicle Saildrone 1023 (SD1023) during the Circumnavigation of Antarctica in 2019. This Saildrone was deployed among two others (SD1020, SD1022) from southern New Zealand in austral fall 2019. These data include atmospheric measurements of barometric pressure, air temperature, PAR, wind speed and gust at height of 3.6m and 3.8m, respectively.

The benthic cover data described herein were generated by the NOAA Ecosystem Sciences Division (former Coral Reef Ecosystem Program, CREP) from the quantitative analysis of photoquadrat benthic images using the image analysis software CoralNet, whereby random points are projected on each image and the benthic elements falling directly underneath each point are identified. The images were collected at sites in Faga'alu Bay in 2020 during belt transect surveys of coral demography.

The U.S. Daily Gridded Climate Normals Datasets are derived from the nClimGrid-Daily Dataset newly produced by the NOAA National Centers for Environmental Information (NOAA NCEI). Climatologically aided interpolation was used to transform an extensive set of station temperature and precipitation values into grids at a high spatial resolution of 1/24° latitude/longitude, or approximately 5 km. The values for each individual grid cell change smoothly from day-to-day through the application of the same methods used to generate daily normals for observation stations.

This dataset consists of discrete profile and surface underway measurements of carbonate chemistry and others hydrographic and chemical parameters, collected during R/V Neeskay and R/V Osprey cruises in Lake Michigan from 2017-05-01 to 2022-04-30. Water chemistry and conductivity-temperature-depth (CTD) profiles were measured at several stations in Lake Michigan, ranging in depth from 10 to 55 m, in a region northeast of Milwaukee Harbor.

We evaluated the influence of diurnal carbonate chemistry variability on the bioerosion rates of two Caribbean sponges: the zooxanthellate Cliona varians and azooxanthellate Cliothosa delitrix. Sponge samples were exposed to four precisely-controlled pH treatments: contemporary static (8.05 ± 0.00; mean pH ± diurnal pH oscillation), contemporary variable (8.05 ± 0.10), future OA static (7.80 ± 0.00), and future OA variable (7.80 ± 0.10). Tank pH conditions measured throughout the entirety of the experiment are provided in the "fullExperiment_pHData.xlsx" file.

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 zooplankton biomass and density data at 15 stations during the open water season in Lake Michigan from 2010-2019. Note, no samples were collected in Lake Michigan in 2012, efforts were instead put towards Lake Huron for the Cooperative Science and Monitoring Initiative (CSMI) that year. Zooplankton density is given in the number of organisms per cubic meter and biomass is given in milligrams per cubic meter.

This dataset, River Chemistry for the U.S. Coast (RC4USCoast), consists of historical records of river chemistry and discharge for 140 monitoring sites along the United States East Coast, the Gulf of Mexico, and the West Coast from 1950 to 2022. RC4USCoast is mostly derived from the Water Quality Database of the U.S. Geological Survey (USGS), but also includes river discharge from the USGS’s Surface-Water Monthly Statistics for the Nation and the U.S. Army Corps of Engineers.
