We applied a multivariate statistical modelling technique called boosted regression trees to derive relationships between environmental conditions and the distribution of the adult stage of the cyclopoid copepod Oithona similis in the Southern Ocean.
A newsurfacewave seismic tomography model of Australia is presented which provides a means of investigating … the lithospheric structure beneath the Proterozoic regions in the west, north and centre of the … continent with improved resolution and reliability.
Microwave remote sensing has been a useful tool to monitor the conditions of sea ice and … ice extent in the polar regions.
Total dissolvable iron (TDFe) was measured in sections of ice cores recovered from Law Dome on the … coast of Wilkes Land, East Antarctica. These samples include ice dating from the Last Glacial Maximum … (LGM), the Last Deglaciation…
The Southern Hemisphere westerlies in the southwest Pacific are known to have waxed and waned numerous times during the last … two glacial cycles, though even semi-continuous histories of the westerlies extend back no more than about 20,000 years.
Shipboard bottle incubation experiments were performed to investigate the effects of iron, light, and silicate on algal production of particulate dimethylsulfoniopropionate (DMSPp) in the Subantarctic Zone (SAZ) south of Tasmania during March 1998.
The influence of irradiance and iron (Fe) supply on phytoplankton processes … was investigated, north (47S, 142E) and south (54S, 142E) of the Subantarctic Front in … austral autumn (March 1998). At both sites, resident cells exhibited nutrient stress (F v / … Fm 0.3).
Subantarctic Southern Ocean surface waters in the austral summer and autumn are characterized by high concentrations of nitrate and phosphate but low concentrations of dissolved iron (Fe, ~0.05nM) and silicic acid (Si, <1µM).
