Water column and sediment geochemical data taken by bottle and bottom samples from NOAA Ship Ronald H. Brown in the southeastern U.S. Atlantic margin from 2019-04-10 to 2019-04-29 (NCEI Accession 0242497)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 26, 2026 | Last Modified: 2021-11-01T00:00:00.000+00:00
This dataset contains water column and sediment geochemical data collected taken by bottle and bottom samples from NOAA Ship Ronald H. Brown (cruise RB19-03) in the southeastern U.S. Atlantic margin in April 2019. Data include nutrient, nitrate, phosphorus, and other chemical characteristics. There are CTD data for this expedition already archived on NCEI under accession number 0207828. This cruise is part of the DEEP SEARCH project, the goal of which is to explore a variety of deep sea ecosystems off the southeastern U.S. Atlantic margin. Data are in CSV format.
