A history of spatial sciences on the Amery Ice Shelf, East Antarctica
... The Antarctic climate system involves many complex interactions between the atmosphere, oceans and ice and is sensitive to variations in these components. Ice shelves represent the ice-ocean-atmosphere interface of the ...

Origin of the Mertz Drift, George V Basin, East Antarctica
... During February-March 2000, a joint Italian/Australian marine geoscience expedition (Project WEGA) discovered and cored a large drift deposit, named the Mertz Drift. The drift is about 390 km 2 in area, and lies in the ...

The annual cycle of southern giant petrels Macronectes giganteus in East Antarctica
... As yet, nothing is known about the at-sea distribution of post- breeding SGPs in East Antarctica. However, birds intending to breed may not travel significant distances from their colonies, even in winter, ...

Measurements of precipitation in Dumont d’Urville, Adélie Land, East Antarctica
... In order to validate and to improve the performance of the models, and to constrain satellite-based measurements, it is necessary to establish and maintain some in situ obser- vation sites in the medium to long term, ...

Quantifying the snowmelt–albedo feedback at Neumayer Station, East Antarctica
... In this study, we used 24 years of high-quality meteorolog- ical and radiation observations from the BSRN station Neu- mayer, situated on the Ekström ice shelf, East Antarctica, to force a surface energy ...

Sea ice diatom contributions to Holocene nutrient utilization in East Antarctica
... The later decline in δ 30 Si diat is concomitant with a documented Antarctic cooling (up to 1°C) between circa 10,000 and 8000 cal years B.P. [Mathiot et al., 2013]. In the region of East Antarctica, this ...

Moisture transport in observations and reanalyses as a proxy for snow accumulation in East Antarctica
... From Fig. 11b, we deduce a straightforward assimilation of radiosoundings by reanalyses when available. The reanal- ysis time series at the stations would be less consistent if the assimilation relied more on the model ...

Nitrate deposition and preservation in the snowpack along a traverse from coast to the ice sheet summit (Dome A) in East Antarctica
... Abstract. Antarctic ice core nitrate (NO − 3 ) can provide a unique record of the atmospheric reactive nitrogen cycle. However, the factors influencing the deposition and preser- vation of NO − 3 at the ice sheet surface ...
