Life hung by a thread: endurance of Antarctic fauna in glacial periods [PDF]

, 2008
Today, Antarctica exhibits some of the harshest environmental conditions for life on Earth. During the last glacial period, Antarctic terrestrial and marine life was challenged by even more extreme environmental conditions.

DASSO: a data assimilation system for the Southern Ocean that utilizes both sea-ice concentration and thickness observations

Journal of Glaciology, 2021
To improve Antarctic sea-ice simulations and estimations, an ensemble-based Data Assimilation System for the Southern Ocean (DASSO) was developed based on a regional sea ice–ocean coupled model, which assimilates sea-ice thickness (SIT) together with sea-

Compilation of Southern Ocean sea-ice records covering the last glacial-interglacial cycle (12–130 ka) [PDF]

Climate of the Past, 2022
Antarctic sea ice forms a critical part of the Southern Ocean and global climate system. The behaviour of Antarctic sea ice throughout the last glacial-interglacial (G-IG) cycle (12 000–130 000 years) allows us to investigate the interactions between sea

Reconstruction of ice-sheet changes in the Antarctic Peninsula since the Last Glacial Maximum [PDF]

, 2014
This paper compiles and reviews marine and terrestrial data constraining the dimensions and configuration of the Antarctic Peninsula Ice Sheet (APIS) from the Last Glacial Maximum (LGM) through deglaciation to the present day.

On the origin of Antarctic marine benthic community structure [PDF]

, 2005
Environmental conditions fostering marine communities around Antarctica differ fundamentally from those in the rest of the world's oceans, particularly in terms of pronounced climatic fluctuations and extreme cold.

Decadal-interdecadal climate variability over Antarctica and linkages to the Tropics : analysis of ice core, instrumental, and tropical proxy data [PDF]

, 2012
The Antarctic continent contains the majority of the global ice volume and plays an important role in a changing climate. The nature and causes of Antarctic climate variability are, however, poorly understood beyond interannual time scales due to the ...

Antarctic Sea Ice Biota [PDF]

American Zoologist, 1991
The sea ice surrounding Antarctica provides an extensive habitat for organisms ranging in size from bacteria to marine birds and mammals. Historically, most of the ecological work on the ice biota has focused in the nearshore land-fast ice. Only in the last decade have there been comparable studies in the deep-water pack ice regions. These studies have
