Physical ice sampling data collected during the BaySys 2017 Churchill River and Mobile Ice Survey, the 2017 Nelson Estuary Landfast Ice Survey and the 2018 Hudson Bay Amundsen Campaign Ice cores were collected using the 9 cm Mark II Kovacs core barrel in conjunction with teams 1, 3, and 4 from 2 mobile ice floes. Cores were bagged in core bags, labeled in the field, and transferred to CNSC. Coreswere cut with a metal Japanese saw into 5 cm portions outside of the CNSC main building (ambient temperature < -20 °C) in order to prevent thawing. All edges of each core section were then trimmed with ceramic knives to remove ice that came into contact with the core barrel or the metal saw. Trimmed sections were double bagged in new Ziploc bags and kept at room temperature in order to melt.
