Vertical ocean profiles collected by a Conductivity-Temperature-Depth (CTD) package in the Amundsen Sea Data DOI: https://doi.org/10.15784/602019 Cite as Stammerjohn, S. (2026) "Vertical ocean profiles collected by a Conductivity-Temperature-Depth (CTD) package in the Amundsen Sea" U.S. Antarctic Program (USAP) Data Center. doi: https://doi.org/10.15784/602019. Abstract This dataset includes 122 CTD vertical profiles acquired during NBP1005 in the Amundsen Sea (02 Dec 2010 to 14 Jan, 2011) using both the ship’s ‘CTD’ (N=87) and a Trace Metal Clean (‘TMC’) CTD (N=35) package. There is an ascii file for each downcast (N=122) and bottle cast (N=80, i.e., not all casts tripped bottles), along with a README file that gives details on the file structure, instrument package, sensors, and post-cruise sensor calibrations/corrections.
