The non-marine Crustacea of Antarctica and the islands of the Southern Ocean: biodiversity and biogeography
Read more of: The non-marine Crustacea of Antarctica and the islands of the Southern Ocean: biodiversity and biogeographyA total of 101 verified species and eight ordinal taxa represent the non-marine Crustacea on Antarctica and the islands of the Southern Ocean. The largely terrestrial Isopoda and Amphipoda are […]

Processes on sediment drifts from 3.5 kHz data, Antarctic Peninsula continental rise
Read more of: Processes on sediment drifts from 3.5 kHz data, Antarctic Peninsula continental riseOn the continental rise west of the Antarctic Peninsula, large sediment drifts preserve a hihg-resolution record of Neogene glaciation, We present a new map of acoustic facies on the continental […]

Mixed biosiliceous-terrigenous sedimentation under the Antarctic Circumpolar Current, Scotia Sea
Read more of: Mixed biosiliceous-terrigenous sedimentation under the Antarctic Circumpolar Current, Scotia SeaSediment supply to the Scotia Sea is controlled by the east-flowing Antarctic Circumpolar Current (ACC) with some Weddell Gyre influence in the south. Near-bottom flow is unsteady with frequent changes […]

The Weddell Sea: contourites and hemipelagites at the northern margin of the Weddell Gyre
Read more of: The Weddell Sea: contourites and hemipelagites at the northern margin of the Weddell GyreFine-grained contourites and hemipelagites occur in the northern Weddell Sea, deposited from the Weddell Gyre. Where bottom currents are intensified over the slope, sandy and silty contourites have been deposited […]

Neogene record of Antarctic Peninsula glaciation in continental rise sediments: ODP Leg 178, Site 1095
Read more of: Neogene record of Antarctic Peninsula glaciation in continental rise sediments: ODP Leg 178, Site 1095Site 1095 is the most distal of three continental rise sites drilled during Ocean Drilling Program Leg 178. A long (600 m), near-continuous section extends from the Holocene down to […]

Short-term variations in the occurrence of heavy metals in Antarctic snow from Coats Land since the 1920s
Read more of: Short-term variations in the occurrence of heavy metals in Antarctic snow from Coats Land since the 1920sShort-term variations in heavy metals concentrations in Antarctic snow have been investigated by analysing 13 metals (Al, V, Cr, Mn, Co, Cu, Zn, Ag, Cd, Ba, Pb, Bi and U) […]

Mating patterns and reversed size dimorphism in southern skuas (Stercorarius skua lonnbergi)
Read more of: Mating patterns and reversed size dimorphism in southern skuas (Stercorarius skua lonnbergi)Numerous explanations exist for the evolution of reversed size dimorphism in raptorial species. A recent study concluded that reversed size dimorphism in skuas and jaegers was probably not attributable to […]

Trios of brown skuas at Bird Island, South Georgia: incidence and composition
Read more of: Trios of brown skuas at Bird Island, South Georgia: incidence and compositionCooperative breeding is unusual in seabirds, but recorded in varying proportions in Brown Skuas (Stercorarius [= Catharacta] lonnbergi). With no evidence for kin selection or delayed dispersal, nor for any […]
