Sea ice can be interspersed vertically with both permeable and impermeable layers. These features can be smaller than a few centimetres but are important for understanding biogeochemical cycles in sea ice. Traditionally…
Antarctic Bottom Water (AABW) is the densest water mass in the world and drives the lower limb of the global thermohaline circulation. AABW is formed in only four regions around Antarctica and Cape Darnley, East Antarctica, is the most recently discovered formation region. Here…
The Sea Ice Physico-Chemistry and Ecosystems 2024 (SLOPE2024) workshop was conducted in the Saroma-ko Lagoon, Hokkaido, Japan from the middle of February to the beginning of March 2024. The aim of SLOPE2024 was to study the physical, chemical…
The Totten Glacier in East Antarctica, with an ice volume equivalent to >3.5?m of global sea-level rise, is grounded below sea level and, therefore, vulnerable to ocean forcing. Here…
Ocean–cryosphere interactions along the Adélie and George V Land (AGVL) coast are investigated using a coupled ocean–sea ice–ice shelf model. The dominant feature of the Mertz Glacier Tongue (MGT), located at approximately 145°E, was a highly productive winter coastal polynya system…
The response of the global water cycle to changes in global surface temperature remains an outstanding question in future climate projections and in past climate reconstructions. The stable hydrogen and oxygen isotope compositions of precipitation (?precip), meteoric water (?MW) and seawater (?SW)…
Antarctic krill (hereafter krill) is the key species of the Antarctic marine ecosystem as well as a target of commercial fishery in the Southern Ocean, which compels careful predictions about potential impacts of Ocean Acidification (OA)…
The Census for Antarctic Marine Life (CAML, IPY Project 53) will investigate the … distribution and abundance of Antarctic marine biodiversity and how it will be affected … by climate change.
The spatial and temporal characteristics of cyclonic eddies in the Antarctic … Divergence off Ade´lie Coast are described using repeated in situ observations between … 2001 and 2003, satellite observations, and results of a high-resolution ocean general … circulation model.
Antarctic coastal polynyas are major areas of intense ocean–atmosphere heat and moisture … flux, and associated high sea-ice production and dense-water formation. Their accurate detection, including an estimate of thin ice thickness, is therefore very important. In this paper…
Antarctic coastal polynyas are important areas of high sea ice production and dense water … formation, and thus their detection including an estimate of thin ice thickness is essential.
This paper introduces the recent activities of sea ice thickness observation around Syowa … station (400E), East Antarctica, conducted by the Japanese Antarctic Research Expedition … (JARE). Ship-borne video observations were conducted on 12 voyages from December … 1987.
: We have conducted two hydrographic cruises crossing Deep Western Boundary Current (DWBC) of Antarctic Bottom Water (AABW) in Australia Antarctic Basin and measured chlorofluorocarbons (CFCs). Western region of the basin (around Kerguelen Plateau)…
Spatio-temporal variability of zooplankton community structure off east Antarctica (90 to 160°E) was studied from 1988 to 1996 based on samples collected by the Japanese icebreaker Shirase. Three community groups with distinctive species compositions were obtained by cluster analysis.
Muon observations are complementary to neutron monitor … observations but there are some important differences in the two techniques. Unlike neutron monitors, muon telescope systems use coincidence techniques to obtain directional information about the arriving particle.
