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... -
Thermal sensitivity of liver cell metabolism of different Antarctic fish species
Temperature dependent cell respiration and energy expenditure for protein synthesis were determined in primary hepatocytes of different fish species of the South Atlantic: the... -
Comparative responses of two dominant Antarctic phytoplankton taxa to interac...
We investigated the responses of the ecologically dominant Antarctic phytoplankton species Phaeocystis antarctica (a prymnesiophyte) and Fragilariopsis cylindrus (a diatom) to a... -

Benthic organisms of the Southern Ocean are particularly vulnerable to ocean acidification (OA), as they inhabit cold waters where calcite-aragonite saturation states are... -
Seawater carbonate chemistry and gene expression levels of the limpet Nacella...
Ocean acidification (OA) could become a serious threat for the Antarctic marine ecosystem over coming years, as the solubility of atmospheric CO2 and CaCO3 minerals increases at... -
Seawater carbonate chemistry and productivity and species composition of a la...
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... -
Seawater carbonate chemistry and gonado-somatic index of three key Antarctic ...
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... -
Seawater carbonate chemistry and thermal tolerance of early development stage...
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... -
Seawater carbonate chemistry and macromolecular data of diatoms
Primary production in the Southern Ocean is dominated by diatom-rich phytoplankton assemblages, whose individual physiological characteristics and community composition are... -
Seawater carbonate chemistry and cardiorespiratory physiology of juvenile Ant...
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;... -
