Water and sediment properties at Polar Fox Lagoon
As the Arctic coast erodes, it drains thermokarst lakes, transforming them into lagoons, and, eventually, integrates them into subsea permafrost. Lagoons represent the first... -
Spectrophotometric measurements of absorption coefficients and optical densit...
Absorption coefficients (abs) and optical density (OD) by total particles, phytoplankton and non-algal particles (NAP) were measured with standard deviation (sd) estimated on... -
Carbon dioxide fluxes and soil, vegetation, meteorological data from a polygo...
Carbon dioxide (CO2) fluxes measurd and modelled over a growing season at a (wet) polygon center and a (dry) polygon rim in the Lena River delta. The NEE fluxes were partitioned... -
Glacier surface velocities in the Ötztal Alps (Austria)
Glacier surface velocities are measured on four neighbouring glaciers in the Ötztal Alps (Austria). Measurements of the annual horizontal flow velocity (Δs/a [m/a]) on... -
Conductivity, temperature and depth (CTD), snow and ice thickess and apparent...
Two separate field excursions were carried out in 2017 to investigate subsea permafrost degradation offshore of the Bykovsky Peninsula in Siberia. In April, four ice cores were... -
Pore water chemistry, grain sizes and sediment temperature of 4 sediment core...
The mobilization of carbon in degrading permafrost is a long-term process and an important feedback upon climate change. Under submarine conditions substantial permafrost... -
Methane production in thawing permafrost is constrained by methanogenic popul...
The release of carbon from newly thawed permafrost is estimated to add between 0.05 and 0.39 °C to the simulated global mean surface air temperature by the year 2300. On decadal... -
Hydrochemistry, runoff and mapped disturbances of Low Arctic Watersheds on He...
Geospatial Data:- Watershed delineation based on hydrology toolbox in ArcGIS (ESRI, version 10.3)- Mapped disturbances based on aerial photographs from 1952 and 1970 (for Ice... -
Measurements in soil and air at Samoylov Station (2002-2018)
Most of the world's permafrost is located in the Arctic, where its frozen organic carbon con-tent makes it a potentially important influence on the global climate system. The... -
Sample site characteristics including mean SOC and SN for permafrost cores co...
Ice rich Yedoma-dominated landscapes store considerable amounts of organic carbon (C) and nitrogen (N) and are vulnerable to degradation under climate warming. We investigate... -
Measurements in soil and air at Bayelva Station
Most permafrost is located in the Arctic, where frozen organic carbon makes it an important component of the global climate system. Despite the fact that the Arctic climate... -
Sediment parameters of the thermokarst lagoon core Iv-99 (Ivashkina Lagoon, B...
We here present lithological, geochronological, and geochemical data from a core drilled in 1999 in the Ivashkina Lagoon on the Bykovsky Peninsula, Northeast Siberia. Supplement... -
Ancient DNA dataset, pollen and non-pollen palynomorphs of four permafrost co...

Seismic Oceanography in the Tyrrhenian Sea - Thermohaline Staircases, Eddies ...
We use seismic oceanography to document and analyze oceanic thermohaline fine structure across the Tyrrhenian Sea. Multichannel seismic (MCS) reflection data were acquired... -
Pore water chemistry and sediment temperature for cores COAST_C-2 and BK-2, c...
Submarine permafrost is more vulnerable to thawing than permafrost on land. Besides increased heat transfer from the ocean water, the penetration of salt lowers the freezing... -
Swimming activity and body size of Pseudocalanus acuspes (KOSMOS 2013, Kristi...
Ocean acidification can impair an animal's physiological performance and energetically demand- ing activities such as swimming. Behavioural abnor- malities and changed activity... -
Flow velocity records at Rock Glacier Outer Hochebenkar (Äußeres Hochebenkar)...
Surface velocities have been regularly monitored at the rock glacier in Outer Hochebenkar, Ötztal Alps, Austria since the early 1950s. This study provides an update to... -
Characteristics of samples obtained during the expedition to Bol'shoy Lyakhov...
The German-Russian project CARBOPERM – Carbon in Permafrost, origin, quality, quantity, and degradation and microbial turnover - is devoted to studying soil organic matter... -
Field data on methane fluxes, temperature, soil gas profiles and microbial ac...
Methane (CH4) production, oxidation, and emission were studied in ponds of the permafrost-affected polygonal tundra in northeast Siberia. Microbial degradation of organic matter... -
Temperature, water level and bathymetry of thermokarst lakes in the continuou...
Thermokarst lakes are typical features of the northern permafrost ecosystems, and play an important role in the thermal exchange between atmosphere and subsurface. The objective...
