The Moores Peak Formation occurs on eastern Hurd Peninsula, Livingston Island, part of the South Shetland Island volcanic arc, which was active during Mesozoic and Cenozoic times. The rocks were […]
The effect of season on “biofilming”;, as a cue for the settlement of marine invertebrate larvae, was investigated in a long‐term field study during the years 1992–1994. The series of […]
Substantial open-ocean phytoplankton blooms in the Antarctic Zone to the northwest of South Georgia, South Atlantic are described. Chlorophyll a, nutrient and physical oceanography data, collected between 2 and 5 […]
Data collected between 1926 and 1990, during the Discovery Investigations and fourteen subsequent cruises, have allowed the description of spatial and temporal variability of temperature, salinity, phosphate, silicate, nitrate and […]
An examination of notothenioid fish of three species, including 23 immature Notothenia coriiceps Richardson, revealed seven acanthocephalan species, including two Echinorhynchida occurring in the intestine and five Polymorphida in the […]
During winter research cruises to South Georgia (1983 and 1993) fish eggs were abundant in the neuston. Examination of the external sculpturing and the micropyle morphology of the eggs collected […]
Cephalopods, like all other animals, have to decide how to allocate resources; maintenance processes, growth of somatic and reproductive tissues, and locomotor activity all have costs. We should like to […]
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 […]
