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... -
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,... -
Second-year sea-ice salinity, temperature, density, oxygen and hydrogen isoto...
Second-year sea-ice thickness, draft, salinity, temperature, and density were measured during near-weekly surveys at the main second-year ice coring site (MCS-SYI) during the... -

Bioacoustic data from an upward looking echosounder, of the model Acoustic Zooplankton Fish Profiler (AZFP) are published. this instrument was deployed in the MOSAiC Central... -
Upward and downward broadband shortwave and longwave irradiance and downward ...
A radiation station was installed on drifting sea-ice in the Arctic Ocean during the MOSAiC expedition between November 2019 and September 2020. The station measured all the... -
Data from downward looking Acoustic zooplankton and fish profiler (AZFP) depl...
Bioacoustic data from an Acoustic Zooplankton Fish Profiler (AZFP) deployed in the MOSAiC Central Observatory the four AZFP frequencies (38, 125, 200 and 455kHz) are published.... -
GEM-2 quicklook total thickness measurements from the 2019-2020 MOSAiC expedi...
The total snow and ice thickness (distance from the snow surface to the ice-ocean interface) was measured by the electromagnetic induction (EM) method. On MOSAiC transects, we...
