Decadal wind-driven east–west asymmetry of chlorophyll-a in the Ross Sea region
Environmental Research LettersThe Ross Sea, the most productive region of phytoplankton around the Antarctic margin, supports the marine food web in the Southern Ocean. However, the long-term variability of chlorophyll-a production is not fully understood.

Marine record of late quaternary glacial-interglacial fluctuations in the Ross Sea and evidence for rapid, episodic sea level change due to marine ice sheet collapse [PDF]
Some of the questions to be addressed by SeaRISE include: (1) what was the configuration of the West Antarctic ice sheet during the last glacial maximum; (2) What is its configuration during a glacial minimum; and (3) has it, or any marine ice sheet ...

Spatial patterns in the evolution of Cenozoic dynamic topography and its influence on the Antarctic continent [PDF]
, 2013 Our knowledge of dynamic topography in Antarctica remains in an infancy stage compared to other continents. We assess the space-time variability in dynamic topography in Antarctica by analysing grids of global dynamic topography in the Cenozoic (and late

Countdown to Consensus for Creating Marine Reserves in Antarctica's Southern Ocean [PDF]
, 2013 The seas surrounding the frozen continent of Antarctica harbor some of the most pristine marine ecosystems left on our planet, supporting an abundant yet fragile web of life.

Recent changes in Antarctic sea ice [PDF]
, 2015 In contrast to the Arctic, total sea ice extent (SIE) across the Southern Ocean has increased since the late 1970s, with the annual mean increasing at a rate of 186×103 km2 per decade (1.5% per decade ...

The Anatomical Record, EarlyView.Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Scientia Marina, 2002 Net samples data from the 15th Italian Antarctic Oceanographic Cruise (Jan-Feb 2000) were analysed to obtain a general picture of the summer distribution pattern, abundance and demography of krill in the western Ross Sea (Antarctica).

Spatial cross-correlation of Antarctic Sea ice and seabed topography [PDF]
A time series of derived sea ice concentrations as observed about Antarctica by the Nimbus-7 Scanning Multichannel Microwave Radiometer (SMMR) satellite in 1983 is considered.

The relationship between form and function of the carnivore mandible
The Anatomical Record, EarlyView.Abstract Dietary morphology diversified extensively in Carnivoraformes (living Carnivora and their stem relatives) during the Cenozoic (the last 66 million years) as they evolved to capture, handle, and process new animal and plant diets. We used 3D geometric morphometrics, mechanical advantage, and finite element analysis to test the evolutionary ...
