Differences in foraging behaviour and feeding ecology in giant petrels
Read more of: Differences in foraging behaviour and feeding ecology in giant petrelsThe two sibling species of giant petrels (northern Macronectes halli and the southern M. giganteus), the dominant scavengers of the sub-Antarctic and Antarctic environment, are one of the best examples […]

The annual and longitudinal variations in plasmaspheric ion density
Read more of: The annual and longitudinal variations in plasmaspheric ion densityThis paper shows that at solar maximum, equatorial ion densities at L = 2.5 are substantially higher at American longitudes in the December months than in the June months. This […]

Ecological drivers of change at South Georgia: the krill surplus, or climate variability
Read more of: Ecological drivers of change at South Georgia: the krill surplus, or climate variabilityMacaroni penguins Eudyptes chrysolophus are thought to be one of the most important mesopredators in the Southern Ocean having a greater impact on prey availability and abundance than any other […]

Antarctic krill under sea ice: elevated abundance in a narrow band just south of ice edge
Read more of: Antarctic krill under sea ice: elevated abundance in a narrow band just south of ice edgeWe surveyed Antarctic krill (Euphausia superba) under sea ice using the autonomous underwater vehicle Autosub-2. Krill were concentrated within a band under ice between 1 and 13 kilometers south of […]

FT-Raman spectroscopic analysis of an Antarctic endolith
Read more of: FT-Raman spectroscopic analysis of an Antarctic endolithThe FT-Raman spectra of an Antarctic endolith from the LTER site at Lake Hoare are reported. The specimen provides an unusual occurrence of endolithic colonization of an igneous rock substratum, […]

Validation of imaging Doppler interferometer winds using meteor radar
Read more of: Validation of imaging Doppler interferometer winds using meteor radarThere has been some debate over the years concerning the accuracy of mesospheric wind observations made using the imaging Doppler interferometer (IDI) technique. The high potential and increasing use of […]

Bathymetric distribution of some benthic and benthopelagic species attracted to baited cameras and traps in the deep eastern Mediterranean
Read more of: Bathymetric distribution of some benthic and benthopelagic species attracted to baited cameras and traps in the deep eastern MediterraneanA series of baited camera and trap experiments in the eastern Mediterranean Sea between 1500 and 4264 m depth attracted a variety of opportunistic scavengers, with species composition changing with […]
