Abstract:
This data set contains profiles of dissolved CH4 concentrations in under-ice seawater (0-75 m water depth) and in new sea ice formed in leads, sampled during N-ICE2015 Floe 1 in February 2015. Data are the basis for the manuscript “Methane release from open leads and new ice following an Arctic winter storm event” by Silyakova and co-authors. The two refrozen leads were sampled on 07/02 (6 cores), 09/02 (6 cores), 10/02 (6 cores) and 12/02 (3 cores). Under-ice seawater was sampled on 02/02, 03/02, 09/02 and 10/02.
