Newly formed sea ice can incorporate considerable amounts of organic matter including phytoplankton during its freezing and growth. This initial incorporation influences the standing stocks of ice algae, a fundamental component of high-latitude marine ecosystems.
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…
The spreading of dense shelf water (DSW) from Antarctic coastal margins to lower latitudes plays a vital role in the ocean thermohaline circulation and the global climate system. Through enhanced localized sea ice production in Antarctic coastal polynyas…
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…
In late winter-early spring 2012, the second Sea Ice Physics and Ecosystems Experiment (SIPEX II) was conducted off Wilkes Land, East Antarctica, onboard R/V Aurora Australis. The sea-ice conditions were characterized by significantly thick first-year ice and snow…
INTRODUCTION The Commission and the Scientific and Conservation Committees have adopted numerous recommendations over the years for strengthening engagement with other organisations. The IWC Secretariat, in collaboration with members of the SC and CC have been working to carry out these mandates…
Preliminary results are presented from the first validation of geophysical data products (ice concentration, snow thickness on sea ice (hs) and ice temperature (TI ) from the NASA EOS Aqua AMSRE sensor, in East Antarctica (in September–October 2003).
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…
Although satellite passive-microwave remote sensing is the main source of global sea-ice … information, the data products have never been adequately validated for East Antarctic … conditions.
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.
