Natural mortality rate in the mackerel icefish (Champscephalus gunnari) around South Georgia
Read more of: Natural mortality rate in the mackerel icefish (Champscephalus gunnari) around South GeorgiaInformation on natural mortality rates of the mackerel icefish (Champsocephalus gunnari) from the period prior to known large-scale commercial harvesting is discussed. After careful consideration of the data and available […]

Comparative FT-Raman spectroscopy of Xanthoria lichen-substratum systems from temperate and antarctic habitats
Read more of: Comparative FT-Raman spectroscopy of Xanthoria lichen-substratum systems from temperate and antarctic habitatsLichens have a primary role in the biodeterioration of rock substrata and in soil formation. In extreme Antarctic rock-face habitats, their exposed epilithic growth form makes them vulnerable to environmental […]

A comparison of adaptive radiations of Antarctic fish with those of nonAntarctic fish
Read more of: A comparison of adaptive radiations of Antarctic fish with those of nonAntarctic fishAntarctic biologists frequently emphasize the differences between the modern Antarctic environment and its fauna, and aquatic habitats and faunas elsewhere in the world. While it is valid to portray Antarctica […]

The nightside ionospheric response to IMF by changes
Read more of: The nightside ionospheric response to IMF by changesA sharp latitudinal gradient in the Doppler spectral width is often observed in the nightside data from the SuperDARN HF radars. We use an excellent conjunction between the Halley HF […]

Deformation history of a Mesozoic forearc basin sequence on Alexander Island, Antarctic Peninsula
Read more of: Deformation history of a Mesozoic forearc basin sequence on Alexander Island, Antarctic PeninsulaThe Mesozoic Fossil Bluff Group of Alexander Island contains trench-slope and forearc basin deposits that formed during the eastward subduction of oceanic crust beneath the Antarctic Peninsula region. The oldest […]

Breakup and conditions for stability of the northern Larsen Ice Shelf, Antarctica
Read more of: Breakup and conditions for stability of the northern Larsen Ice Shelf, AntarcticaThe breakup of ice shelves has been widely regarded as an indicator of climate change1, with observations around the Antarctic Peninsula having shown a pattern of gradual retreat, associated with […]

High latitude Eocene climate deterioration: evidence from the northern Antarctic Peninsula
Read more of: High latitude Eocene climate deterioration: evidence from the northern Antarctic PeninsulaClay mineral, sedimentological and geochemical data show that the northern Antarctic Peninsula (Seymour Island, La Meseta Formation) experienced a climatic deterioration from very warm, non-seasonally wet conditions at the end […]
