CTD data from 9 casts at the oxygen-deficient zone of the Eastern Tropical North Pacific (ETNP), R/V Atlantis cruise AT37-12, April-May 2017 (NCEI Accession 0278066)

Preview graphic

This dataset contains biological, chemical, optical, and physical data collected on R/V Atlantis during cruise AT37-12 in the North Pacific Ocean from 2017-04-25 to 2017-05-13. These data include Oxygen in volts, conductivity, density, depth, dissolved Oxygen, fluorescence, salinity calculated from CTD primary sensors, sound velocity, turbidity, water pressure, and water temperature. The instruments used to collect these data include CTD profiler. These data were collected by Dr Andrew Babbin of Massachusetts Institute of Technology and Dr Stefan M Sievert of Woods Hole Oceanographic Institution as part of the "Collaborative Research: Environmental Drivers of Chemoautotrophic Carbon Production at Deep-Sea Hydrothermal Vents - Comparative Roles of Oxygen and Nitrate (vent O2 NO3 roles)" project. The Biological and Chemical Oceanography Data Management Office (BCO-DMO) submitted these data to NCEI on 2020-01-03.

The following is the text of the dataset description provided by BCO-DMO:

AT37-12 CTD data at the Eastern Tropical North Pacific
