Diversity and distribution patterns in high southern latitude sponges. [PDF]

PLoS ONE, 2012
Sponges play a key role in Antarctic marine benthic community structure and dynamics and are often a dominant component of many Southern Ocean benthic communities.

Correlation and interaction between temperature and freeze-thaw in representative regions of Antarctica

International Journal of Digital Earth, 2022
As the most sensitive and direct indicator of global climate change, the freezing and thawing of the Antarctic ice sheet is of great significance for research on surface mass and energy balance.

Gene Transfer Agent g5 Gene Reveals Bipolar and Endemic Distribution of Roseobacter Clade Members in Polar Coastal Seawater

Diversity, 2022
The Roseobacter clade represents one of the most abundant groups of marine bacteria and plays important biogeochemical roles in marine environments. Roseobacter genomes commonly contain a conserved gene transfer agent (GTA) gene cluster.

An evaluation of Antarctic sea-ice thickness from the Global Ice-Ocean Modeling and Assimilation System based on in situ and satellite observations [PDF]

The Cryosphere, 2022
Antarctic sea ice is an important component of the Earth system. However, its role in the Earth system is still unclear due to limited Antarctic sea-ice thickness (SIT) data. A reliable sea-ice reanalysis can be useful to study Antarctic SIT and its role

Decoupling of the Surface and Bottom‐Intensified Antarctic Slope Current in Regions of Dense Shelf Water Export

Geophysical Research Letters, 2023
The Antarctic Slope Current is guided by the topographic gradient of the Antarctic continental slope and creates a dynamical barrier between the continental shelf and the open ocean.

Global biogeographic patterns in bipolar moss species [PDF]

Royal Society Open Science, 2017
A bipolar disjunction is an extreme, yet common, biogeographic pattern in non-vascular plants, yet its underlying mechanisms (vicariance or long-distance dispersal), origin and timing remain poorly understood.

A Tropospheric Assessment of the ERA-40, NCEP, and JRA-25 Global Reanalyses in the Polar Regions [PDF]

, 2007
The reliability of the global reanalyses in the polar regions is investigated. The overview stems from an April 2006 Scientific Committee on Antarctic Research (SCAR) workshop on the performance of global reanalyses in high latitudes held at the British ...

The first comprehensive description of the biodiversity and biogeography of Antarctic and Sub-Antarctic intertidal communities [PDF]

, 2016
Aim To describe the distribution of biodiversity and biogeographical patterns of intertidal organisms in southern temperate and polar waters. We hypothesized that there would be differences in community structure between the Antarctic, which is most ...

Low genetic diversity in Antarctic populations of the lichen-forming ascomycete Cetraria aculeata and its photobiont [PDF]

Polar Research, 2012
Lichens, symbiotic associations of fungi (mycobionts) and green algae or cyanobacteria (photobionts), are poikilohydric organisms that are particularly well adapted to withstand adverse environmental conditions.
