King crabs threaten seafloor life near Antarctica
King crabs and other crushing predators are thought to have been absent from cold Antarctic shelf waters for millions of years. Scientists speculate that the long absence of crushing predators has allowed the evolution of a unique Antarctic seafloor fauna with little resistance to predatory crabs. A recent study indicates that one species of king crab has moved 120 km across the continental shelf in West Antarctica and established a large, reproductive population in the Palmer Deep along the west Antarctic Peninsula.

Climate in the past million years determined greatly by dust in the Southern Ocean
A group of scientists led by researchers from the Universitat Autònoma de Barcelona (UAB) and the Swiss Federal Institute of Technology (ETH Zürich) has quantified dust and iron fluxes deposited in the Antarctic Ocean during the past 4 million years. The research study published in Nature evidences the close relation between the maximum contributions of dust to this ocean and climate changes occurring in the most intense glaciation periods of the Pleistocene period, some 1.25 million years ago.

Scientists from British Antarctic Survey have discovered previously unknown volcanoes in the ocean waters around the remote South Sandwich Islands. Using ship-borne sea-floor mapping technology during research cruises onboard the RRS James Clark Ross, the scientists found 12 volcanoes beneath the sea surface -- some up to 3 km high. They found 5 km diameter craters left by collapsing volcanoes and seven active volcanoes visible above the sea as a chain of islands. (2011-07-11)

Antarctic krill help to fertilize Southern Ocean with iron
A new discovery reveals that the shrimp-like creature at the heart of the Antarctic food chain could play a key role in fertilizing the Southern Ocean with iron -- stimulating the growth of phytoplankton (microscopic plant-like organisms).

Warming ocean layers will undermine polar ice sheets
Warming of the ocean's subsurface layers will melt underwater portions of the Greenland and Antarctic ice sheets faster than previously thought, according to new University of Arizona-led research. The research, based on 19 state-of-the-art climate models, proposes a new mechanism by which global warming will accelerate the melting of the great ice sheets during this century and the next. Such melting would increase the sea level more than already projected. (2011-07-03)
