A single colony of the non-native grass Poa pratensis L., which was introduced inadvertently to Cierva Point, Antarctic Peninsula, during the 1954–1955 season, was still present during a survey in […]
We review the general search problem of how to find randomly located objects that can only be detected in the limited vicinity of a forager, and discuss its quantitative description […]
A major ductile fault zone, the eastern Palmer Land shear zone, has been identified east of the spine of the southern Antarctic Peninsula. This shear zone separates newly identified geological […]
Under the typical high-latitude conditions of temperature, productivity and settlement of chlorophyll and phaeophytin to the sediment, many benthic organisms in the Antarctic show strong seasonal variation. Although meiofauna comprise […]
The validity of a radiative transfer model can be checked either by comparing its results with measurements or with solutions for artificial cases. Unfortunately, neither type of comparison can guarantee […]
The comparison between electric (electric-conductivity measurement (ECM) and dielectric profiling (DEP)) and chemical (sulphate and chloride) depth profiles along the first 400 m of the EPICA-Dome C ice core revealed […]
Early embryos, blastulae, prisms and 4-arm plutei of the Antarctic shallow-water echinoid Sterechinus neumayeri were subjected to a temperature/pressure regime from -1.2 to +2.5°C and from 1 to 250 atm. […]
Conventional frost-point hygrometers observe frost on their cold point by optical means [1,2,3], thereby requiring several micrometres of ice to form. We have developed a new hygrometer which uses surface […]
The Antarctic Circumpolar Current (ACC) crosses rugged topography to the north of South Georgia. In this region the subsurface expression of the Polar Front (PF) is generally thought to occur […]
In terms of the convention governing the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR), management advice for the Antarctic krill (Euphausia superba) fishery should take the needs […]
Observations of field strengths of signals from a number of VLF transmitters, after propagation over long paths in the Earth–ionosphere waveguide, have been used to examine changes in the daytime […]
CRP-2/2A hole, drilled at 77.006oS and 163.719oE, about 14 km east of Cape Roberts, in the Ross Sea, reached 624 metres below sea floor and recovered a thick Miocene-Oligocene succession […]
