Antarctic conservation science is crucial for enhancing Antarctic policy and understanding alterations to terrestrial Antarctic biodiversity. Antarctic conservation will have limited long-term impacts in the absence of large-scale biodiversity data, but if such data were available…
Aim … Polar and alpine plants live at the edge of their physiological limits. Thus, relatively small changes in climate can have disproportionate effects on biological and ecological processes. Antarctic mosses display highly variable micro-topography (canopy architecture)…
In late winter-early spring 2012, the second Sea Ice Physics and Ecosystems Experiment (SIPEX II) was conducted off Wilkes Land, East Antarctica, onboard R/V Aurora Australis. The sea-ice conditions were characterized by significantly thick first-year ice and snow…
Total biomass and areal biomass density are often necessary to establish ecological relationships and enable informed management decisions, in particular setting fisheries catch limits.
Within the Pycnogonida, genetic studies have … revealed that Colossendeis megalonyx Hoek (Challenger … Report, Zoology, 3(X), 1–167, 1881), consists of a complex of … several cryptic or overlooked species.
The global distribution, sources, and propagation of atmospheric waves in the … equatorial upper troposphere and lower stratosphere were investigated using an … atmospheric general circulation model with T106L60 resolution (120-km horizontal … and 550-m vertical resolution).
The event that occurred approximately 8200 years ago is the largest excursion in climate since the beginning of the Holocene. In this event we observe the climatic response to a perturbation which provides a probe with which to investigate the stability of interglacial climate.
This work has been the first application of DGT samplers for measuring metals in water and sediment porewater in the Antarctic … environment, and whilst DGT water sampling was restricted to quantification of Cd, Fe and Ni…
Ice shelves play a major role in the discharge of ice from Antarctica both from iceberg calving and basal melt, and processes of ocean-ice interaction beneath the shelf are of increasing scientific interest.
As with human cytomegalovirus (HCMV) infection of humans, murine CMV (MCMV) infection is … widespread in its natural host, the house mouse Mus domesticus, and may consist of mixed … infection with different CMV isolates.
We present results of modelling iceberg tracks around East Antarctica, using the observed … long-term tracks of massive icebergs as reference data.
The phase lag between atmospheric composition (air bubbles) and temperature (water isotopes) can be quantified from ice cores provided that the age difference between entrapped air and the surrounding air can be correctly estimated. This difference depends on the lock-in depth (LID)…
Bubbles of air trapped in ice sheets provide an important record of past atmospheric gas composition. Understanding of climate change and atmospheric composition over the last 400,000 years has been greatly improved using ice core analysis.
The Antarctic Pack-Ice Seals program (APIS) is an initiative of the SCAR Expert Group on Seals aimed at quantifying the role of pack-ice seals (crabeater, leopard and Ross) in the Southern Ocean. A central feature of APIS was a synoptic…
A 7 year time series of austral summer expendable bathythermograph (XBT) sections between Tasmania and Antarctica is used to describe the subsurface structure of Southern Ocean interannual temperature anomalies. Comparison of the discontinuous XBT record with a continuous (weekly average)…
A method has been developed for the routine determination of four arsenic species (arsenite, arsenate, monomethylarsenic and dimethylarsenic) in natural water, and has been applied to a study of arsenic cycling in open ocean (Atlantic and Southern Ocean) and estuarine (Huon Estuary, Tasmania)…
