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:
Antarctic and Southern Ocean science is vital to understanding natural variability, the processes that govern global change and the role of humans in the Earth and climate system. The potential for new knowledge to be gained from future Antarctic science is substantial. Therefore…
Blue whale populations each produce distinctive repeated songs that are stable over periods of decades, and can be used to identify where each population resides and moves. In the Southern Hemisphere and northern Indian Ocean, there are at least seven distinct populations based on their songs…
The decrease of atmospheric CO2 concentration recorded in Antarctic ice around 1600 AD is one of the mostsignificant atmospheric changes to have occurred during the last millennia, before the onset of the industrial period.Together with the temperature decrease…
Gases released by human activity (greenhouse and ozone depleting gases) are responsible for global change. They are long-lived and well-mixed in the atmosphere. The Antarctic regions, remote from industrial and land plant activity are ideally located to measure global changes in the gases.
Oceanographic instruments suspended beneath the Amery Ice Shelf, East Antarctica, have recorded sporadic pressure decreases of 10–20 dbar over a few days at three sites where basal marine ice growth is expected.
Abstract Samples of marine ice were collected from … the Amery Ice Shelf, a large embayed ice shelf in East … Antarctica, during the Austral summer of 2001–2002. The samples came from a site ~90 km from the iceberg … calving front of the shelf…
Geisz et al. report an unexpected consequence of climate … change, implicating glacier meltwater as a source for DDT … in coastal Antarctic seas (1). Hypothetically, glaciers may … act as secondary sources for DDT and there may be a link … to climate change. However, their data are sparse, variable…
The Amery Ice Shelf, East Antarctica, undergoes high basal melt rates near the southern … limit of its grounding line where 80% of the ice melts within 240km of becoming afloat. A considerable … portion of this later refreezes downstream as marine ice.
Determining the mass balance of the Greenland and Antarctic ice sheets (GIS and AIS) has long … been a major challenge for polar science. But until recent advances in measurement technology…
