Snow on Antarctic sea ice plays a complex and highly variable role in air-sea-ice interaction processes and the Earth's climate system. Using data collected mostly during the past 10 years, this paper reviews the following topics:
Protoxylem plays an important role in the hydraulic function of vascular systems of both herbaceous and woody plants, but relatively little is known about the processes underlying maintenance of protoxylem function in long-lived tissues. In the present study…
1.Ecosystem change is predicted to become more prevalent with climate change. Widespread dieback of cushion plants and bryophytes in alpine fellfield on Macquarie Island may represent such change. Loss of the keystone endemic cushion plant, Azorella macquariensis…

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.
Repeat summer hydrographic observations along … 140E are used to document significant changes in the … properties of the Ade´lie Land Bottom Water (ALBW) between the mid-1990s and 2002–2003. Water on the 28.35 … kgm3 neutral density surface cooled by 0.2C and … freshened by 0.
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…

Over the past 50 years the sub-Antarctic has experienced increases in temperature and radiation. Little scientific attention has been paid to the ecophysiological response of vascular plant species growing on these islands and it is unclear what impact climate change may have on these species.
A biological/oceanographic survey was conducted around the Antarctic Divergence (AD) off Adelie Land, Antarctica by the RTV Umitaka-Maru III of Tokyo University of Fisheries in the 1995/1996 Austral summer. Investigations were included (1) characteristics of oceanic structure, (2)…
