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,...

Benthic organisms of the Southern Ocean are particularly vulnerable to ocean acidification (OA), as they inhabit cold waters where calcite-aragonite saturation states are...

Copepod samples were taken during the Antarctic expedition PS 79 (ANT XXVIII/2) with RV Polarstern (Cape Town – Cape Town, 3 Dec 2011 – 5 Jan 2012). Copepods were collected at...

The Western Antarctic Peninsula (WAP), one of the most productive regions of the Southern Ocean, is currently undergoing rapid environmental changes such as ocean acidification...

The timing and intensity of snowmelt processes on sea ice are key drivers determining the seasonal sea-ice energy and mass budgets. In the Arctic, satellite passive microwave...

We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis antarctica (a prymnesiophyte) and Fragilariopsis cylindrus (a diatom) to a...

The present study examines how different pCO2 acclimations affect the CO2- and light-dependence of photophysiological processes and O2 fluxes in four Southern Ocean (SO) key...

In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne and Gattuso, 2011) was used to compute a complete and consistent...

Despite the fact that ocean acidification is considered to be especially pronounced in the Southern Ocean, little is known about CO2-dependent physiological processes and the...

Snow depth measurements were obtained using a MagnaProbe (Snow-Hydro, Fairbanks, Alaska, USA) during walking surveys on most ice stations during PS111. The walks were randomly...

Snow depth measurements were obtained using a MagnaProbe (Snow-Hydro, Fairbanks, Alaska, USA) during walking surveys on most ice stations during PS124. The walks were randomly...

Time series data of physical oceanography (seawater conductivity, temperature, pressure, salinity) and ocean current velocities were obtained from moorings AWI252-3, AWI253-3...

During the PS118 research cruise with the German research vessel RV POLARSTERN (Feb 2019- April 2019), sediments were collected with a multicorer from 7 stations along a 400...

Temperature dependent cell respiration and energy expenditure for protein synthesis were determined in primary hepatocytes of different fish species of the South Atlantic: the...

Abstract: This data set comprises time series of the monthly sea-ice area (SIA) in the Northern and Southern Hemisphere based on numerical models participating in CMIP6 (Climate...

Abstract: This data set comprises time series of the monthly sea-ice area (SIA) in the Northern Hemisphere (1 file) and in the Southern Hemisphere (1 file). SIA is derived from...

CO2 atmospheric pressure is increasing since industrial revolution, leading to a lowering of the ocean surface water pH, a phenomenon known as ocean acidification, with several...

In order to allow full comparability with other ocean acidification data sets, the R package seacarb (Lavigne et al, 2014) was used to compute a complete and consistent set of...

Primary production in the Southern Ocean is dominated by diatom-rich phytoplankton assemblages, whose individual physiological characteristics and community composition are...

To date, numerous studies have shown negative impacts of CO2-acidified seawater (i.e. ocean acidification, OA) on marine organisms including calcifying invertebrates and fishes;...
