Seasonal Change of Antarctic Sea Ice Cover
Science, 1975The winter expansion of the sea ice surrounding Antarctica and the subsequent retreat of the ice in summer may be linked with the wind stress acting on the Southern Ocean in conjunction with the heat exchange in open water regions within the ice fields.

Productivity of Microalgae in Antarctic Sea Ice
Science, 1965Midsummer productivity of Antarctic microalgae, commonly occurring in brown sea ice along the west coast of the Palmer Peninsula, averaged more than 900 milligrams of carbon per cubic meter per hour, with an assimilation number of about 2.6. The rate of photosynthesis increased with light intensity to a maximum of about 18,000 lux, above which some ...

Ambient noise under Antarctic sea ice
The Journal of the Acoustical Society of America, 1976Underwater ambient noise spectra are described for data recorded during late spring conditions under the ice sheet in McMurdo Sound. The ambient noise was at all times marked by intense biological activity, but a diurnal component became apparent during a three-day recording period.

Dissolved carbohydrates in Antarctic sea ice
Antarctic Science, 2001Concentrations of dissolved monocarbohydrates (MCHO) and polycarbohydrates (PCHO) were analysed in a variety of ice habitats from summer Weddell Sea sea ice (surface ponds, ice cores, gap layers and platelet ice). The dissolved organic carbon (DOC) pool in these habitats was also measured and the contribution of carbohydrate to this pool was assessed ...

Geophysical Research Letters, 2019
Following a multidecade increase, Antarctic sea ice declined drastically during austral spring 2016. Suggested causes of the sea ice decline include lingering effects of the 2015/2016 extreme El Niño and a tropical Indian Ocean teleconnection to high ...

Phytoplankton Blooms Under Antarctic Sea Ice
2021Areas covered in compact sea ice are often assumed to prohibit upper ocean photosynthesis. Yet under-ice phytoplankton blooms (UIBs) have increasingly been observed in the Arctic, driven by changes...

Mechanical Properties of Antarctic Sea Ice
Journal of Offshore Mechanics and Arctic Engineering, 1988Abstract Ice samples were extracted from a land-fast ice sheet of 90 cm thickness at Lutzow-Holm Bay in the Antarctica. The ice samples were then shipped to a cold room in Tokyo, and unconfined uniaxial compression tests and fracture toughness tests were performed for a wide range of loading rate under temperature varying from −5°C to ...

Acoustic reflectivity of Antarctic sea ice
'Challenges of Our Changing Global Environment'. Conference Proceedings. OCEANS '95 MTS/IEEE, 2002An Upward Looking Sonar (ULS) operating at 300 kHz has been built and deployed off the Antarctic coast during 1994 as part of the Australian climate related sea ice research program. The ULS was moored 150 m below the surface in water of 3 km depth and returned data spanning 11 months.

1994
The sea ice cover in the Antarctic is one of the most climatically important features of the Southern Hemisphere. Its seasonal variation in extent is from 4 million km2 in summer (February) to 20 million km2 in winter (September) (Zwally et al. 1983).
