Conductivity-Temperature-Depth (CTD) and Geochemistry Data from 2024 Expedition of the Canadian Coast Guard Ship Louis S. St-Laurent to the Beaufort Gyre

Contains data from a hydrographic cruise conducted about the aboard the Canadian Coast Guard Ship (CCGS) Louis S. St-Laurent, August 29th to September 26th, 2024 under the Beaufort Gyre Observing System (BGOS)/Joint Ocean Ice Study (JOIS). Data were collected under the National Science Foundation (NSF) award "AON (Arctic Observing Network) Collaborative Research: Continuation of long-term Beaufort Gyre observations in 2020-2024 to enhance understanding of the Arctic's role in climate variability" in collaboration with researchers from Fisheries and Oceans Canada at the Institute of Ocean Sciences (Paul Macoun, Bill Williams and Sarah Zimmermann, Institute of Ocean Sciences).
There were 61 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 a single netcdf file as 1-decibar (db) averaged profiles. Cruise documentation is available as a text file. Geochemistry data are provided in a separate excel spreadsheet.
