This dataset contains chemical and physical data collected on R/V Atlantis during cruise AT39-01 in the North Atlantic Ocean from 2011-10-11 to 2017-10-20. These data include Iron, Manganese, and Silicon. The instruments used to collect these data include Inductively Coupled Plasma Optical Emission Spectrometer and ROV Jason. These data were collected by C. Geoffrey Wheat of University of Alaska Fairbanks as part of the "Collaborative Research: Completing North Pond Borehole Experiments to Elucidate the Hydrology of Young, Slow-Spread Crust (North Pond 2017)" project and "Center for Dark Energy Biosphere Investigations (C-DEBI)" program. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-10-14.
