Fossil angiosperm wood is abundant within Cretaceous and Tertiary sediments on the Antarctic Peninsula. The wood, which represents the trunks and branches of large forest trees that once grew on […]
Fossil wood of the Atherospermataceae from the upper Cretaceous of James Ross Island, Antarctica, is described for the first time and represents the earliest record of this family in the […]
Data from HF-radars are used to make the first simultaneous conjugate measurements of the dayside reconnection electric field. A period of 4 h around local magnetic noon are studied during […]
Ice disturbance is possibly the major structuring element of polar nearshore biological communities. Effects range from encapsulation by ice forming on rock substrata to gouging and trampling by bergs. Some […]
Two 10cm lengths of firn core from the Dyer Plateau (700° 3l’S, 65°0l’W), Antarctic Peninsula, were used to carry out a laboratory experiment to investigate the migration of methane sulphonate, […]
Intra-specific foraging niche partitioning can arise due to gender differences or individual specialisation in behaviour or prey selection. These may in turn be related to sexual size dimorphism or individual […]
The understanding of sea ice mass balance processes requires continuous monitoring of the seasonal evolution of the ice thickness. While autonomous ice mass balance buoys (IMB buoys) deployed over the […]
By thinning and accelerating, West Antarctic ice streams are contributing about 10% of the observed global sea level rise. Much of this ice loss is from Pine Island Glacier, which […]
Repeat-pass ICESat altimetry has revealed 124 discrete surface height changes across the Antarctic Ice Sheet, interpreted to be caused by subglacial lake discharges (surface lowering) and inputs (surface uplift). Few […]
