Snowpit raw data collected during the MOSAiC expedition
This dataset captures the yearlong evolution of physical properties of the snow cover over Arctic sea ice during the MOSAiC expedition (October 2019-September 2020). It also... -
Law Dome Br, Na, I (1927-2016) and sea ice (1973-2015)
The Law Dome site is ideal for the evaluation of sea ice proxies due to its location near to the Antarctic coast, regular and high accumulation throughout the year, an absence... -
Victoria Land Antarctica Pb and Ba concentrations and Pb isotope ratios 1872-...
Pb and Ba concentrations and Pb isotopic compositions are reported for firn core and snow pit samples from Victoria Land, Antarctica, dating from 1872 AD to 1994 AD. From... -
Stable oxygen isotopes of Antarctic snow pits
Stable oxygen analyses and snow accumulation rates from snow pits sampled in the McMurdo Dry Valleys have been used to reconstruct variations in summer temperature and moisture... -
Temperature time series and physical properties of snow samples of a high-arc...
Independent measurements of radiation, sensible and latent heat fluxes and the ground heat flux are used to describe the annual cycle of the surface energy budget at a... -
Stable-isotope records from Dronning Maud Land, Antarctica
The European Project for Ice Coring in Antarctica (EPICA) includes a comprehensive pre-site survey on the inland ice plateau of Dronning Maud Land. This paper focuses on the... -
First results from stable-istope measurements on ice cores from Dronning Maud...
The European Project for Ice Coring in Antarctica (EPICA) focuses on the drilling of two deep ice cores, the first at Dome C and the second at Kohnen station (75°00' S, 0°04' E)... -
Density, δ¹⁸O and accumulation rates from snow pits on the Filchner-Ronne Ice...
Accumulation rates in the eastern part of Ronne Ice Shelf were determined by isotopic stratigraphy (18O). The samples were taken from snow-pits dug during the Filchner I and II... -
Physical and chemical investigations on ice cores from the Filchner-Ronne Ice...
The accumulation and distribution of the 2H content of near-surface layers in the eastern part of the Ronne Ice Shelf were determined from 16 firn cores drilled to about 10 m... -
Density and stable oxygen isotope profiles of four snow pits from Berkner Isl...
The ice cap on Berkner Island is grounded on bedrock within the Filchner-Ronne Ice Shelf and is, therefore, expected to be a well-suited place to retrieve long-term ice-core... -
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... -
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...
