Conductivity-Temperature-Depth (CTD) and Geochemistry Data from 2021 Expedition of the Canadian Coast Guard Ship Louis S. St-Laurent

Contains data from a hydrographic cruise conducted about the aboard the Canadian Coast Guard Ship, CCGS Louis S. St-Laurent, August 19 to September 16th, 2021 under the Beaufort Gyre Observing System (BGOS)/Joint Ocean Ice Study (JOIS). There were 57 conductivity temperature depth (CTD) casts performed using a SBE911+ CTD system with 24 10-Liter (L) Niskins. The CTD data for down casts are provided in 1-decibar (db) averaged files (*.cnv), in Seabird's text format with one file per cast and separate files. Cruise documentation is available as a text file. Geochemistry data are provided in a separate excel spreadsheet.
