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 ...

Primary Production in Antarctic Sea Ice
Science, 1997A numerical model shows that in Antarctic sea ice, increased flooding in regions with thick snow cover enhances primary production in the infiltration (surface) layer. Productivity in the freeboard (sea level) layer is also determined by sea ice porosity, which varies with temperature. Spatial and temporal variation in snow thickness and the proportion

On the radiation characteristics of Antarctic Sea Ice [PDF]
Atmosphere-Ocean, 2000 Abstract Radiative measurements were carried out continuously during a cruise from Australia to Antarctica during austral summer 1995/96. Both shortwave and longwave radiative fluxes were measured. Some of the results are: The incoming solar radiation had a mean value of 217 W m–2; this was a relatively weak value due to the large amount of fractional ...

Over the 40‐year satellite record, there has been a slight increasing trend in total annual mean Antarctic sea ice extent of approximately 1.5% per decade that is made up of the sum of significantly larger opposing regional trends.

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 ...

Antarctic Sea Ice: 1972-1975 [PDF]
Geographical Review, 1979 rT HE areal extent and variability of sea ice is one of the most important of the numerous components that interact to produce global climatic patterns, even for areas far removed from the polar zones. Sea ice in the south-polar region exhibits significant seasonal and interannual variations that from a practical viewpoint are important for Antarctic ...

Sea ice macrofauna in the Antarctic and the Arctic
Journal of Marine Systems, 1991Abstract Sea ice faunal assemblages (= sympagic assemblages) with invertebrates and fish are recorded both in the Antarctic and the Arctic. Primary structuring factors of the assemblages are age and drift pattern of the ice, hydrography and water currents in the immediate vicinity of the ice, and distance to the benthic habitat.

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 ...

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 ...
