Raw Ship-based Trackline Geophysical Data (MGD77) from the Antarctica Weddell Sea acquired during R/V Nathaniel B. Palmer expedition NBP1702 (2017)

This data set was acquired with a Echosounder, Navigation System and Gravimeter during R/V Nathaniel B. Palmer expedition NBP1702 conducted in 2017 (Chief Scientist: Dr. Rebecca Robinson, Investigators: Dr. Rebecca Robinson, Dr. Bob Anderson). These data files are of MGD77 format and include Bathymetry, Gravity Field, Gravity Free Air Anomaly and Navigation data that have not been processed. Data were acquired as part of the project(s): Collaborative Proposal: A Field and Laboratory Examination of the Diatom N and Si Isotope Proxies: Implications for Assessing the Southern Ocean Biological Pump; Water Mass Structure and Bottom Water Formation in the Ice-age Southern Ocean. Funding was provided by NSF award(s): PLR15-42962 and by: PLR13-41464.
