We present a relative sea-level (RSL) history, constrained by AMS radiocarbon-dated marine–freshwater transitions in isolation basins from a site adjacent to the Lambert Glacier, East Antarctica. The RSL data suggest […]
Late Holocene changes in the ultraviolet radiation (UVR) penetration in a lake in the Larsemann Hills (East Antarctica) were reconstructed using sediment core proxies based on fossil pigments (scytonemins and […]
Mass mortality of echinoids is well documented, and has potentially profound effects on benthic communities. However, no study to date has quantitatively investigated how regular, predictable events such as winter […]
We have studied the short-term effect of the October–November 2003 series of solar proton events on the middle atmosphere. Using the proton flux measurements from the GOES–11 satellite as input, […]
Historical perspectives have shown how several scientific disciplines have developed their Antarctic component over the last century. Antarctic science has changed from a secondary activity of privately organised expeditions by […]
Recently hearing Fred Singer from the USA lecture on what he perceives to be the uncritical ways in which global change has been attributed to anthropogenic effects reminded me of […]
We are embarked on a decade of celebrations of the national expeditions of what is now termed the Heroic Age. Exploring the Antarctic – the great unknown continent – a […]
The joint inspection report by Australia, Peru and the United Kingdom, presented at the last ATCM in Stockholm, contained an unusual recommendation. On the basis of the science that they […]
Deployment of processed natural substrata is a common method of investigating early settlement and recruitment processes, but has been under-utilised as a multi-depth method for barnacle study and analysis. Replicate, […]
Dosidicus gigas (the Jumbo flying squid) supports a major fishery in the Eastern Pacific. The commercial fishery consists of a multinational jigging fleet, and the emission of light from these […]
During Austral summer 2001/02 the spatial distribution of phytoplankton and zooplankton communities and associated production processes were investigated in waters to the north of the island of South Georgia. Nearest […]
The Jurassic Latady Basin (southern Antarctic Peninsula) developed in a broad rift zone associated with the early stages of Gondwana extension. Early Jurassic sedimentation (~185 Ma) occurred in small, isolated […]
