Sediment samples, ammonium and methane data collected during R/V Atlantis cruise AT26-13 in the northern Gulf of Mexico from 2014-03-31 to 2014-04-21 (NCEI Accession 0175003)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 06, 2026 at 02:16 AM | Dataset Last Updated: August 07, 2018 at 12:00 AM
This dataset contains sediment samples, ammonium concentrations and methane data collected during R/V Atlantis cruise AT26-13 in the northern Gulf of Mexico from March 31 to April 21, 2014. The R/V Atlantis cruise AT26-13 set sail with the HOV Alvin on board on March 30, 2014. GoMRI funded Alvin dives occurred on March 31st and April 1st of 2014. This dataset includes sediment samples collected on those dives. In addition, it also includes water column profiles collected to measure dissolved ammonium concentrations using advanced auto-analyzer equipment from the Martens lab at UNC-Chapel Hill, and methane data taken from around the northern gulf with the METS sensor.
