Model calculations of the age of firn air across the Antarctic continent
The age of firn air in Antarctica at pore close-off depth is only known for a few specific sites where firn air has been sampled for analyses. We present a […]

A comparison of net and acoustic estimates of krill density in the Scotia Sea during the CCAMLR 2000 Survey
Read more of: A comparison of net and acoustic estimates of krill density in the Scotia Sea during the CCAMLR 2000 SurveyA multi-ship, multi-national survey to assess the acoustic biomass of Antarctic krill across the Scotia Sea was undertaken in January and February 2000. In addition, a total of 135 Rectangular […]

Frost flowers on sea ice as a source of sea salt and their influence on tropospheric halogen chemistry
Read more of: Frost flowers on sea ice as a source of sea salt and their influence on tropospheric halogen chemistryFrost flowers grow on newly-formed sea ice from a saturated water vapour layer. They provide a large effective surface area and a reservoir of sea salt ions in the liquid […]

Role of antioxidant defense during different stages of preadult life cycle in European corn borer (Ostrinia nubilalis, Hubn.): diapause and metamorphosis
Read more of: Role of antioxidant defense during different stages of preadult life cycle in European corn borer (Ostrinia nubilalis, Hubn.): diapause and metamorphosisAntioxidant enzymes, total glutathione (GSH), and ascorbic acid (ASA) were determined in whole body homogenates of nondiapausing larvae, diapausing larvae during the diapausing period (October, December, and February), and in […]

Winter dispersal of leopard seals (Hydrurga leptonyx): environmental factors influencing demographics and seasonal abundance
Read more of: Winter dispersal of leopard seals (Hydrurga leptonyx): environmental factors influencing demographics and seasonal abundanceThe dynamics of leopard seat Hydrurga leptonyx abundance and residency were investigated both within and between years at Bird Island, South Georgia, using observations of tagged and untagged individuals. Seals […]

Seasonal ventilation of the cavity beneath Filchner-Ronne Ice Shelf simulated with an isopycnic coordinate ocean model
Read more of: Seasonal ventilation of the cavity beneath Filchner-Ronne Ice Shelf simulated with an isopycnic coordinate ocean model[1] The ocean cavity beneath Filchner-Ronne Ice Shelf is observed to respond to the seasonal cycle of water mass production on the continental shelf of the southern Weddell Sea. Here […]

Oceanographic observations at the Amundsen shelf break
Read more of: Oceanographic observations at the Amundsen shelf breakIntroduction The continental shelf environment of the Amundsen and Bellingshausen seas differs markedly from that of the other circumpolar seas, where water temperatures are close to the surface freezing point […]

Middle Jurassic air fall tuff in the sedimentary Latady Formation, eastern Ellsworth Land
Read more of: Middle Jurassic air fall tuff in the sedimentary Latady Formation, eastern Ellsworth LandRhyolitic volcanism along the proto-Pacific margin of Gondwana occurred at intervals throughout the Jurassic. Silicic melt generation has been interpreted as a result of interaction between mantle plumes and subduction […]

Kin or self-recognition? Colonial fusibility of the bryozoan Celleporella hyalina
Read more of: Kin or self-recognition? Colonial fusibility of the bryozoan Celleporella hyalinaWe estimated fusion frequency with respect to coancestry in the bryozoan Celleporella hyalina, whose briefly planktonic sexually produced larvae settle on algal substrata and proceed to form encrusting colonies by […]
