The flavonoid composition of Bryum algens from Antarctica is presented. It is shown that there exist two extreme patterns, with a range of intermediate forms. The patterns range from a […]
Echo integration of biological organisms with a low target strength can be difficult because of the problem of setting suitable pre-integration thresholds, and this is particularly acute with higher frequencies, […]
Two dominant Antarctic copepod species, Rhincalanus gigas and Calanus simillimus, were sampled at stations along a 420 km transect running from Maurice Ewing Bank (50°S, 42°W) towards South Georgia (54°S, […]
The lipid and hydrocarbon composition of two species of Antarctic copepod, Rhincalanus gigas and Calanus simillimus, was investigated at two contrasting sites. Differences in the quantity of total lipid between […]
IN 1978 Mercer1 discussed the probable effects of climate warming on the Antarctic Ice Sheet, predicting that one sign of a warming trend in this region would be the retreat […]
Early Cretaceous plutonic rocks at Creswick Peaks in NW Palmer Land, Antarctic Peninsula show evidence of synmagmatic crustal extension and deformation during emplacement and cooling at 141 ±2 Ma. Deformation […]
