This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, water temperature, salinity and other parameters collected from profile discrete observations using CTD, Niskin Bottles and other instruments during the R/V Knorr cruise KN2011-4 (EXPOCODE 316N20110426), in the North Atlantic Ocean from 2011-04-26 to 2011-05-02. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry.

This dataset contains profile discrete measurements of dissolved inorganic carbon, total alkalinity, pH on total scale, water temperature, salinity and other parameters collected from profile discrete observations using CTD, Niskin Bottles and other instruments during the R/V Pelican cruise RAPID 3 (EXPOCODE 32PE20180319), in the Gulf of Mexico from 2018-03-19 to 2018-03-23. Increasing amounts of atmospheric carbon dioxide from human industrial activities are causing changes in global ocean carbon chemistry.

This data package contains MOCNESS (Multiple Opening/Closing Net Environmental Sensing System) profile data and other ichthyoplankton and decapod specimen identification data collected during Natural Resource Damage Assessment (NRDA) Plankton Survey Nick Skansi PC3 (NSPC3) in the Gulf of Mexico from 2010-09-25 to 2010-10-03. This survey was part of a series of NS NRDA cruises conducted in 2010 and 2011 to evaluate the distribution and densities of ichthyoplankton and other zooplankton in northern Gulf of Mexico waters potentially affected by the Deepwater Horizon Oil Spill (DWHOS).

Jurisdictional managers have expressed concerns that nutrients from the village of Vatia, Tutuila, American Samoa, are having an adverse effect on the adjacent coral reef ecosystem. Excess nutrient loads promote increases in algal growth that can have deleterious effects on corals, such as benthic algae outcompeting and overgrowing corals. Nitrogen and phosphorus can also directly impact corals by lowering fertilization success, and reducing both photosynthesis and calcification rates.

The data described here result from benthic coral demographic surveys within belt transects of specified length and width for two life stages (juveniles and adults) in Fagaʻalu, American Samoa in 2020. The data provide information on adult coral colony counts, morphology, size, partial mortality (old and recent dead), presence and causation of disease and other compromised health conditions, including bleaching. Juvenile colony surveys include morphology and size. Taxonomic identification of adult colonies is to the species level and genus level for juveniles.

This dataset includes discrete sample and profile data collected during the Canadian Beaufort Sea Marine Ecosystem Assessment (CBS-MEA) F/V Frosti cruise 18DN190802 (EXPOCODE 18DN20190802) in the Arctic Ocean, Beaufort Sea from 2019-08-02 to 2019-09-09. These data include water temperature, salinity, dissolved oxygen, dissolved inorganic carbon (DIC) and total alkalinity. Starting in 2017, Fisheries and Oceans Canada (DFO) conducted a survey of marine fishes and their habitats on the Canadian Beaufort Shelf and slope in August and early September each year.

This package contains underway and station data collected during R/V Pelican cruise PE17-23 in the Gulf of Mexico. Data included are six expendable bathythermograph (XBT) profiles of temperature, resistance, and sound velocity, as well as underway measurements of barometric pressure, relative humidity, and light transmission. Additional underway measurements and CTD station measurements are available in NCEI Accession 0172092. Provisional underway measurement locations are provided as interpolated from navigation data available in that accession.

This dataset contains salinity, temperature, pressure collected by Marine Robotics Vehicles (MRV) ALTO autonomous profiling float 11066 deployed from the icebreaker research vessel Laura Bassi in Ross Gyre from 2020-01-11 to 2020-02-16. This float was also programmed to avoid ice but this feature was not necessary over the short period of sampling reported here. The nominal accuracy of the MRV SBE CTD measurements is 0.004 mS/cm, 0.002 C, and 0.25 m, respectively.

This dataset includes dissolved inorganic carbon (DIC), total alkalinity (TA), partial pressure of carbon dioxide (pCO2), methane (CH4), nutrients, oxygen, particulate organic carbon, nitrogen (POC and PON) and pigment concentrations from discrete water samples, and photosynthetically active radiation (PAR). Data were collected weekly at the fixed station (4 depths) from 2016 to 2022 during the Bedford Basin Monitoring Program (BBMP) by Bedford Institute of Oceanography (BIO) of Fisheries and Oceans, Canada (DFO).

This dataset contains oceanographic data collected from NOAA Ship OKEANOS EXPLORER in the North Atlantic Ocean from 2021-06-30 to 2021-07-29. Data acquisition from shipboard sensors includes navigational data, meteorological data (wind), and oceanographic data (bathythermograph, sound velocity probe, thermosalinograph). Additional data include Profile Data (ASVP, CTD, and XBT), event logs, images, ROV ancillary data, and specimen data.
