Holes drilled into thin areas of the Brunt Ice Shelf encounter a layer of liquid brine less than 1 m thick approximately at sea-level. Assuming the brine to be moving…1 January, 1975
The fauna reported here was obtained from the Legoupil Formation in the north-western part of the Antarctic Peninsula (Fig. 1), which has been assigned a Cretaceous age on the basis…Read more on First marine Triassic fauna from the Antarctic Peninsula

Twelve sheathbills, Chionis alba, 12 South Georgian diving petrels, Pelecanoides georgicus, and 5 common diving petrels, P. urinatrix, collected at Bird Island, South Georgia, were examined for helminth parasites. These…1 January, 1973
An idealized model of the vertical distribution of the electron concentration in the E- and F-regions of the ionosphere is developed in which the model parameters are given by simple…Read more on A simple model of the vertical distribution of electron concentration in the ionosphere

Mosses are generally considered to be land plants although a few species are found growing submerged in streams and shallow areas of lakes. But there is now increasing evidence that…1 January, 1973
Using growth rates estimated from lichens growing on introduced substrata on Signy Island, South Orkney Islands (lat. 61 °S., long. 45 °W.), the two most recent moraines of a glacier…Read more on Estimates of lichen growth rates in the maritime Antarctic
