    "description": "This dataset contains water column and sediment geochemical data taken by bottle and bottom samples from research vessel Atlantis (cruise AT41) in the southeastern U.S. Atlantic margin in August 2018. Data include nutrients, nitrate, phosphorus, and other chemical characteristics. There are CTD data for this expedition archived at NCEI under accession number 0177873.\n\nThis cruise is part of the DEEP Sea Exploration to Advance Research on Coral\/Canyon\/Cold seep Habitats (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.",
