Abstract:
This dataset contains the measurements of snow/SSL (surface scattering layer) depth or melt pond depth from a walk across the sea ice floe (called long transect) during ice station PS149_25-1 (floe 2b) of the PS149 CONTRASTS expedition. The long transect was traversed across the ice floe with a GPS-equipped MagnaProbe to obtain statistically representative distributions of snow/SSL and pond depth. 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. Along the same transect track the total sea ice thickness (sea ice thickness + snow / SSL or melt pond depth) was measured unsing a Geophex Ltd. GEM2-730 instrument. These GEM measurements are available in the other dataset of this collection: https://doi.pangaea.de/10.1594/PANGAEA.996933. Since the GEM and MagnaProbe measurements at this station were conducted on two consecutive days, ice floe drift between the surveys would make precise spatio-temporal co-location of the datasets unreliable. Therefore, the measurements are provided as separate datasets without any drift correction. However, both were collected along the same marked transect track. The measurements of all other PS149 ice stations are co-located and available here: doi:10.1594/PANGAEA.996908. 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: https://doi.pangaea.de/10.1594/PANGAEA.996907.
