MicroCT density and specific surface area snowpit profiles during the MOSAiC ...
Cylindrical snow and ice samples of radii 44 mm, 68 mm, 88 mm and a maximum height of 110 mm were taken from the field using a cylindrical drill and transported to the ship in... -
Snowpit stable isotope profiles during the MOSAiC expedition
In the designated snowpits on the MOSAic expedition a 100cm3 sample of snow was measured for density in the field, approximately every 3 vertical centimetres. The same snow... -
Snowpit salinity profiles during the MOSAiC expedition
In the designated snowpits, 100cm3 of snow was collected in the field, melted and measured for salinity in the laboratory on board Polarstern. Salinity of the melted snow... -
Beryllium-7 concentrations in snow during the MOSAiC expedition
For bulk snow samples, we collected the full snow column (snow surface to ice surface). First, the depth of snow was measured with a ruler. Next, a measured area of the snow... -
Snow permittivity measured during the MOSAiC expedition
Dielectric permittivity (ε′) and dielectric loss (ε″) measurements were made of discrete snow layers and at fixed vertical intervals. Measurements were made using the Stevens... -
Snowpit height measurements during the MOSAiC expedition
We used a regular foldable wooden ruler to measure the height of the snow and the SSL. The ruler was also used for height readings for all other measurements. 0 cm is the... -
Snowpit snow density cutter profiles measured during the MOSAiC expedition
A density cutter of fixed volume (100 cm3) and known weight was used to measure the density profile of snow/SSL in 3 cm intervals. The height of the sampled volume was recorded... -
Snowpit temperature profiles measured during the MOSAiC expedition
The snow temperature was measured using a waterproof thermometer with a needle probe. A ruler was used to determine the measuring height. 0 cm indicates the snow-ice interface.... -
Snowpit snow water equivalent collected with an ETH tube during the MOSAiC ex...
SWE is the amount of water contained within the snowpack. To determine SWE, the snow depth and density are required. Snow depth (HS) is related to SWE by the local bulk density... -
Snowpit surface type observed during the MOSAiC expedition
For the majority of snowpits the snow surface type was recorded by the observer. The documented surface types include; new snow, rime, surface hoar, glazed, drifted snow, wet,... -
Snowpit near-infrared (NIR) images collected during the MOSAiC expedition
A NIR camera allows a measurement of the reflectance of the snow profile wall to identify layers of snow grains with different specific surface area (SSA) with a spatial... -
Snowpit metadata TXT files collected during the MOSAiC expedition
The metadata txt files can be used to obtain a quick overview of one snowpit event. They give details on date of the event, location of the snowpit, start time, GPS file name... -
Snowpit overview photos collected during the MOSAiC expedition
Overview photos were taken when arriving at the snowpit site of interest and before the snowpit was excavated. A standard digital camera (Olympus tough TG-5) was used to... -
Snowpit GPS locations during the MOSAiC expedition
A Garmin GPSmap 62sc device was taken to each snowpit event to get the location measurement. If no GPS file is found, further GPS details can be retrieved from the SMP... -
Snowpit multi-image photogrammetry images collected during the MOSAiC expedition
The small-scale surface roughness is important for scattering of shortwave visible and higher-frequency microwave radiation. A standard digital camera (Olympus tough TG-5) and a... -
Snowpit SnowMicroPen (SMP) force profiles collected during the MOSAiC expedition
The SnowMicroPen (SMP) is a portable device for high-resolution in-situ measurements of penetration resistance in snow and can be correlated to snow microstructure (density,... -
Stable water isotopes of snow during MOSAiC expedition
Snow samples were collected from several locations on the main MOSAiC ice floe on weekly basis. Snow samples for measurement of stable water isotopes (δ18O, δD,) were collected... -
Ridge snow oxygen and hydrogen isotope data MOSAiC Leg 4 (PS122/4)
Oxygen (dO18) and hydrogen (dH) isotope ratio data from snow samples taken during MOSAiC leg 4 (PS122.4). Snow samples were taken from several locations around the central... -
SnowMicroPen raw data (sn_smp_31, sn_smp_43 and sn_smp_49) during MOSAiC expe...
The SnowMicroPen (SMP) is a portable device for high-resolution in-situ measurements of penetration resistance in snow and can be correlated to snow microstructure. The...
