The ‘Norfolk Meeting’ was held in November 2005 as a joint IWC SO GLOBEC initiative to … outline a program of work to expedite integrative circumpolar analyses of existing cetacean … data series for the Antarctic. Our aim was to use the results of these analyses to summarise, on a circumpolar scale…
Recent research indicates extensive basal melting near the deep grounding lines of major … Antarctic outlet glaciers. Further…
Oceanographic and seismic observations of the ocean beneath the Amery Ice Shelf, taken … over several seasons, describe a general pattern consistant with an “ice pump” mechanism. The ice pump is a general description of the thermohaline circulation under ice shelves.
Life beneath the Antarctic ice shelves is surprisingly abundant and diverse. This study … documents the Holocene seabed community beneath the Amery Ice Shelf, East Antarctica, based on fossil analysis of a 47 cm long sediment core. The surface samples from this core … reveals a rich modern fauna…
We evaluated the weekly NIC (National Ice Center) ice chart dataset with in situ sea-ice … thickness observations from the ASPeCt (Antarctic Sea Ice Processes and Climate) program … during the 1995 to 2000 time period. Five ship voyages from May/June 1995, August 1995, May/June 1998…
The efforts of Patterson and co-workers (Murozumi et al., 1969) to accurately measure Pb … concentrations in Greenland and Antarctic snow and ice produced the first reliable … determination of Pb pollution of the Earth’s polar ice sheets. Since then…
The microparticle record from the Dome Summit South ice core, Law Dome, East Antarctica … is investigated using a Coulter Multisizer to provide concentration and size distribution at … selected depths. This core site has an unusually high accumulation rate (640 kg m2/a) during … the Late Holocene…
Surface snow accumulation along the Chinese ITASE traverse line was measured using … bamboo stakes. Stakes along the initial (coastal) 300 km of the line were installed in 1997. The stake network was extended to 465 km in 1998, to 1100 km in 1999 and finally to 1228 … km (from the coast to Dome A)…
The internal structure of the Law Dome ice cap is being investigated by studying ice cores obtained from several sites along the summit - Cape Folger line. Profiles of measured physical properties for four of the ice cores from near the margin of the ice cap are presented.
From its original formulation in 1990 the International Trans-Antarctic Scientific Expedition … (ITASE) has had as its primary aim the collection and interpretation of a continent-wide array of … environmental parameters assembled through the coordinated efforts of scientists from several nations.
Over the past three years a successful collaboration between a university scientist, the AADC … and EPPS has occurred, where old field data from the 1980s has been resurrected using new … mapping technologies to produce a detailed vegetation map of Heard Island. In this paper…
The southern elephant seal (Mirounga leonina) population at Macquarie Island represents … about 10% of the world’s population. The number of adult females breeding at the island has … decreased substantially since the first whole island census was conducted in 1952.
We determined the effects of UVR (280 – 400 nm) on Antarctic marine protists over the … summer of 2001/02 in incubation experiments with light exposures of PAR, PAR+UVAR and … PAR+UVAR+UVBR.
A survey of the size characteristics of the population of icebergs around the whole of the … Antarctic coastline was carried out using synthetic aperture radar images. A total of 36…
Prior to environmental legislation in the 1980s, anthropogenic waste in Antarctica was often deposited into … landfill sites or into the sea. This resulted in metal contamination in terrestrial and near-shore marine … environments. In this study…
A mechanism where reconnection between the Solar Interplanetary Magnetic Field and the … Geomagnetic field, deposits energy in the polar atmosphere was first observed in Antarctica. The propagation and attenuation of plasma waves occurs in the polar ionospheric waveguide … at 300km altitude…
The collapse of the Larsen A and B and other ice shelves fringing the Antarctic Peninsula … coastline raises questions about the status of ice shelves in other parts of the continent. Are … the large ice shelves along the East Antarctic coast also in danger of permanent collapse…
The initial aim of the research, beginning in the 02/03 season, was to undertake some … regional mapping of the ice shelf, and to determine if marine ice could be differentiated from … meteoric ice employing the seismic technique. In 2002/2003…
An air-borne radio echo sounding survey was conducted over the Amery Ice Shelf, East … Antarctica, in December 2003. Nine transverse profiles were obtained approximately normal … to the flow direction, together with one longitudinal profile for a total length of flight lines of … about 1000 km.
Comparison of surface elevations measured by terrestrial survey in 1987 over the grounded … part of Totten Glacier with elevations measured by the Geophysical Laser Altimeter System … on NASA’s ICESat in 2003 shows that there has been substantial lowering of the surface of … around 10 m over 16…
We present in situ observations of atmospheric and fast-ice parameters at Davis … (68°35'S, 77°58'E), East Antarctica. Surface measurements from 1969–2003 reveal … negative trends for summer and autumn surface-air temperatures, yet positive annual, winter and spring trends.
Resolving the spatial variability in the population structure of Antarctic krill (Euphausia superba) requires a synoptic … sample, as in the design of the CCAMLR 2000 Survey. However, this approach is not appropriate for assessing … temporal variability.
Chlorophyll-a (Chl-a) concentrations in surface waters were measured at 137 hydrographic stations occupied by four … research vessels participating in the CCAMLR 2000 Survey and the values were compared to estimates from data … acquired by the SeaWiFS satellite.
