https://www.pangaea.de/ information publisher tableDigital This dataset contains measurements of snow/SSL (surface scattering layer) depth or melt pond depth co-located with total ice thickness estimates from a walk across the ice floe (called long transect) conducted during the ice station indicated in the title during the PS149 CONTRASTS expedition. The transect was marked with flags at its corner points to ensure that a similar track was measured during repeated visits to the ice floe. A GPS-equipped MagnaProbe was used to measure snow/SSL and melt pond depth, while a Geophex Ltd. GEM-2-730 instrument was used to measure total sea ice thickness. Total sea ice thickness refers to the distance between the instrument and the ice–ocean interface. Accordingly, if present, snow/SSL or melt pond depth must be subtracted from this total thickness to obtain the actual sea ice thickness estimate. More detailed explanations about the data processing and the co-location of both measurements can be found in the comment section of the dataset collection: doi:10.1594/PANGAEA.996908. completed Ringel, Maximilian Harald
