This dataset consists of satellite measurements of global and regional ocean color data obtained by the Sea-viewing Wide Field-of-view Sensor (SeaWiFS), in orbit on the OrbView-2 (formerly SeaStar) platform. The concentration and predominant identity of substances and particles in the euphotic (lighted) zone of the upper ocean influences the apparent color of the ocean, which can range from deep blue to varying shades of green and ruddy brown. Living phytoplankton (which contain chlorophyll and associated photosynthetic pigments), inorganic sediments, detritus (particulate organic matter) and dissolved organic matter all contribute to the color of the ocean. SeaWiFS acquires approximately 15 pole-to-pole orbital swaths of data per day, and approximately 90% of the ocean surface is scanned every two days. The file's content consists of raw radiance counts from eight bands (six in visible and two in near infrared spectrum), calibration data, navigation data, instrument telemetry and selected spacecraft telemetry. While level 2 historic data is open to the public, level 1 data is restricted to users covered by SeaWiFS CoastWatch contract due to limitations associated with commercial data. The OrbView-2 spacecraft, which carried the SeaWiFS instrument, stopped communicating with Earth-based data stations in December 2010. After several months of attempts to revive the link, GeoEye, the company that operated the spacecraft, officially ended any further attempts at recovery.

NOAA CoastWatch distributes L3 level chlorophyll a concentration data derived from measurements take by the VIIRS sensor (Visible Infrared Imaging Radiometer Suite) aboard the Suomi-NPP satellite. Chlorophyll values were calculated using NOAA-MSL12 NRT processing with LAND+CLDICE+HIGLINT+HISATZEN+HISOLZEN masking.

The dataset contains satellite-derived sea-surface ocean color (chlorophyll-a) measurements collected by means of the Visible Infrared Imaging Radiometer Suite (VIIRS) sensor onboard the NASA Suomi National Polar-Orbiting Partnership (Suomi NPP) spacecraft. The data is available at weekly and monthly intervals at a spatial resolution of 0.05 degrees, from 2012 to present. The geographic coverage is global.

These time-series data sets are from a Current Profiler and other instruments on 2 moorings at NOAA Data Observatory "M2" on the southeastern Bering Sea Shelf. Moorings 21bsm-2a and 21bsp-2a (biophysical & ADCP, respectively) were deployed in May, 2021 (NOAA Ship Oscar Dyson DY21-03) and recovered in January, 2022 (21bsm-2a) and May, 2022 (21BSP-2A, NOAA Ship Oscar Dyson, DY22-06). Surface mooring 21bsm-2a (indicated by "m") instrumentation included PMEL MTR temperature recorders, SeaBird SBE-37 (Microcat), SBE-39, SBE-56, SBE 16 plus (Seacat) profilers, a SeaBird Optical UV nitrate sensor (SUNA V2), a ProOceanus Mini Total Dissolved Gas Pressure (TDGP) sensor and WetLabs EcoFluorometers. WeatherPak surface instruments on the float were lost at sea with suspected sea ice damage. A subsurface 300 kHz Teledyne RDI Acoustic Doppler current profiler (ADCP) mooring 21bsp-2a (indicated by "p") on a second mooring recorded water-column currents. Data include Zonal (U), Meridional (V) and Vertical (W) current components, temperature, conductivity, salinity, pressure, water depth, oxygen concentration, calculated oxygen percent saturation, nitrate, total dissolved gas pressure and raw chlorophyll fluorescence. Data are in NetCDF. The cruise was funded by NOAA, Pacific Marine Environmental Laboratory EcoFOCI program and the Arctic Climate Program (ACP). Deployment and recovery operations on cruises were managed by EcoFOCI personnel from NOAA/PMEL. Mooring time series data were processed at NOAA/PMEL/EcoFOCI using standard techniques. Time is recorded as UTC. Data contacts: Phyllis Stabeno, Shaun Bell, Ryan McCabe, Peggy Sullivan.

Ocean color remote sensing provide routine, synoptic observations of the ocean surface at spatial and temporal resolutions not attainable by moored or ship-based platforms. Ocean color sensors measure the spectral distribution of reflected sunlight, which can be used to infer the contents of the water, including chlorophyll a concentrations, a proxy for phytoplankton biomass. Phytoplankton are the base of the marine food web and are critical regulators of key biogeochemical processes.

The Visible and Infrared Imager/Radiometer Suite (VIIRS) is a multi-disciplinary instrument that is being flown on the Joint Polar Satellite System (JPSS) series of spacecraft, including the Suomi National Polar-orbiting Partnership (S-NPP) that launched in October 2011. JPSS is a multi-platform, multi-agency program that consolidates the polar orbiting spacecraft of NASA and the National Oceanic and Atmospheric Administration (NOAA). S-NPP is the initial spacecraft in this series, and VIIRS is the successor to MODIS for Earth science data product generation. VIIRS has 22 spectral bands ranging from 412 nm to 12 nm. There are 16 moderate-resolution bands (750m at nadir), 5 image-resolution bands (375m), and one day-night band (DNB).

Chemical, physical and profile oceanographic data were collected aboard NOAA Ship Pisces in the Gulf of Mexico from 2010-09-09 to 2010-09-17 in response to the Deepwater Horizon Oil Spill event on April 20, 2010, by the Subsurface Monitoring Unit (SMU), which consisted of multiple government and corporate agencies. These data include CDOM fluorescence, conductivity, dissolved oxygen, fluorescence, hydrostatic pressure, salinity, sound velocity, temperature and water density. The instruments used to collect these data included CTD, fluorometer and oxygen meter along with other physical sampling devices. More specific information about each dataset is located in their individual metadata records. The CTD data underwent preliminary quality assurance and control procedures at the National Coastal Data Development Center (NCDDC). Cruise level information consisting of data management documents, cruise reports and plans, videos and pictures, and other miscellaneous documentation were gathered by the data managers.
