The aim of drilling ice cores is to obtain paleoatmospheric information of wide significance. However, the concentrations of chemicals found in the- ice are determined both by the atmospheric concentrations,…Read more on Location, movement and reactions of impurities in solid ice
1 January, 1996 by Eric Wolff
Ice cores have now become established as one of the primary archives of paleoclimatic information, covering timescales from seasonal up to 100,000 years or more. In the polar ice sheets,…Read more on The record of aerosol deposited species in ice cores, and problems of interpretation
1 January, 1995
The Antarctic Ice Sheet has greatly affected global climate, sea level, ocean circulation, and southern hemisphere biota during Cenozoic times. Much of our understanding of the evolution of the ice…Read more on Geology and seismic stratigraphy of the Antarctic Margin
1 January, 1995
This chapter reviews the tectonic evolution of the East Scotia Sea, testing and extending previously published conclusions in light of the additional and expanded data sets now available. The East…1 January, 1995
Heavy mineral provenance studies can aid reservoir description in deep marine depositional systems by providing a clearer understanding of the lateral extent of discrete sediment bodies. In this study the…1 January, 1995
The ANTOSTRAT Antarctic Peninsula Regional Working Group has compiled digital navigation data acquired during seismic reflection surveys of the Antarctic Peninsula continental margin and adjoining areas. Digital navigation data were…Read more on The ANTOSTRAT Antarctic Peninsula Regional Working Group digital navigation compilation

The Fossil Bluff Grqup (FBG: ?Bathpnian-Albian) is the fill of a forearc basin which lay between the Antarctic Peninsula volcanic arc and an accretionary complex (LeMay Group) to the west…1 January, 1995 by Howard Roscoe
Part 1 Historical frontiers: vibrational spectroscopic contributions to chemisorption and catalysis. Part 2 Instrumentation: recent advances in kinetic infrared spectroscopy; spectroscopic concentration determination without calibration; scope and limitations of concentration-modulated…Read more on Ozone measurements with star-pointing spectrometers

Nitrate is one of the major impurities in polar snow, and is relatively easy to analyse. Large amounts of data therefore exist, including some from cores extending into the last…1 January, 1994 by Alistair Crame
One of the most important breakthroughs in Antarctic geological research over the last three decades has been the elucidation of the continent’s fossil record. Although fossils have been known since…1 January, 1994
The International Geophysical Year of 1957–58 demonstrated the effective use of the Antarctic for peaceful international scientific activity, and the Antarctic Treaty of 1961 acknowledges the important contribution of science.…1 January, 1994
Information on the expenditure and investment of energy in southern elephant seals, Mirounga leonina , was collected during breeding and molt over four field seasons at South Georgia. Weight and…Read more on Expenditure, investment, and acquisition of energy in southern elephant seals

The Wainimala Group rocks of southwestern Viti Levu, Fiji, represent part of an Oligocene-Miocene island arc. Some of the early volcanism in this arc took place on a substrate of…1 January, 1994
In the Antarctic winter of 1991 an extensive series of micro- meteorological and snow cover measurements were made as part of the second Stable Boundary Layer Experiment (STABLE II) at…Read more on Modelling mass and energy exchange over polar snow using the DAISY model

The spatial extent and temporal behaviour of quasi-periodic (QP) intensity modulations of 0.5-2kHz ELF-VLF emissions were investigated in a comparative study of data collected at three Antarctic stations. Frequently, the…Read more on The ULF modulation of ELF-VLF emissions close to the magnetospheric boundary
