The Remote Sensing Reflectance (RRS) suite provides the remote sensing reflectance at wavelength λ (nm)—the ratio of water-leaving radiance to downwelling irradiance just above the surface (units sr⁻¹). Variables are named by their band center (e.g., Rrs_412, Rrs_443). Rrs_λ is the foundational observable used to retrieve products such as chlor_a, Kd_490, IOPs, and to support algorithm development

The Chlorophyll-a data suite provides global, gridded composites of surface chlorophyll-a concentration (a proxy for phytoplankton biomass). CHL supports time-series and climatologies, anomaly detection, ecosystem and fisheries applications, and teaching/training, and pairs well with AVW, PAR, Kd(490), SST, and winds for environmental context. Note: retrievals in optically complex coastal/inland w

The KD data suite provides diffuse attenuation coefficient of downwelling irradiance at 490 nm, Kd_490, which quantifies how quickly blue-green light diminishes with depth—an indicator of water clarity and the depth to which sunlight penetrates. Kd_490 is generated from ocean-color reflectance using the KD2 algorithm. Lower values indicate clearer water (deeper light penetration); users commonly a

The Ocean Color (OC) data suite provides calibrated, atmospherically corrected ocean-optics measurements and derived biogeophysical products. This data suite includes the Apparent Optical Properties (AOP) and provides satellite-derived measures of the interaction between solar radiation and the upper ocean. AOPs are “apparent” because they depend not only on the inherent optical properties (IOPs)

NASA Earthdata CMR2024 · Array · NetCDF

Level 1A (L1A) data are reconstructed, unprocessed instrument data at full resolution, time-referenced, and annotated with ancillary information. This ancillary information can include radiometric and geometric calibration coefficients and georeferencing parameters (e.g., platform ephemeris).

NASA Earthdata CMR2024 · collection

Level-0 data are reconstructed, unprocessed instrument and payload data at full resolution, with any and all communications artifacts (e.g., synchronization frames, communications headers, duplicate data) removed.

The Coastal Zone Color Scanner (CZCS) on Nimbus-7 was designed for the quantitative remote sensing of the bio-optical properties of marine waters by measuring the visible spectral signatures of the sea. The CZCS has six spectral channels and five visible channels sensing solar backscattered radiance and one infrared channel sensing emitted thermal radiance. The CZCS measured radiances are used to

In English: Multichannel and single channel seismic reflection, high resolution seismic, sononbuoys, multibeam soundings, gravimetric and magnetic profiles were made. The object of the investigation was an integrated study of the margins and basins of the northern Antarctic Peninsula and its prolongation toward the East, between the Weddell and Scotia Seas. In this expedition, work was done in the

NASA Earthdata CMRcollection

In English This group of data contains the information acquired in the campaign HR053 by the oceanographic vessel Hesperides within the MAGIA project. Reference data was obtained for navigation, positioning, and vessel altitude; bathymetry and morphology of the marine floor; atmospheric, physical, chemical and acoustical parameters of the water column; geophysical parameters and acoustic profiles

In English Oceanographic parameters were acquired and preprocessed with special interest in the transects J-1 (Weddell Sea), H-G (Drake Passage), and E-C (Weddell Sea); the first and last complement the data acquired during the campaign E-DOVETAIL, whose fundamental objective was to detect and quantify the intermediate water flux exported from the Weddell Sea to Scotia Sea. The second section is a
