Lipids as trophic markers in Antarctic krill. II. Lipid composition of the body and digestive gland of Euphausia superba in controlled conditions. Marine Ecology Progress Series, 2005 (Ref: 12195)
Category 1: Peer-reviewed literature

To examine the potential of lipids as dietary markers in Euphausia superba Dana, juvenile … krill were fed 4 phytoplankton diets (diatoms, cryptomonads, dinoflagellates and thraustochytrids … over a range of food concentrations) and 2 species of zooplankton (rotifers and Artemia sp.) for 20 d.

Lipids as trophic markers in Antarctic krill. III. Temporal changes in digestive gland lipid composition of Euphausia superba in controlled conditions. Marine Ecology Progress Series, 2005 (Ref: 12194)
Category 1: Peer-reviewed literature

Two phytoplankton diets with markedly different fatty acid (FA) profiles (thraustochytrid … and diatom over a range of concentrations) were fed to juvenile Euphausia superba Dana to … evaluate the time lapse required for the development of trophic lipid signatures in the digestive gland … (DG).

Relevance of silicon isotopes to Si-nutrient utilization and Si-source assessment in Antarctic waters. Global Biogeochemical Cycles, 2005 (Ref: 11928)
Category 1: Peer-reviewed literature

[1] We analyzed d29Si of dissolved silicate for eight water column profiles across the … Southern Ocean (south of Australia in spring 2001) from the Seasonal Ice Zone (SIZ) north to the Subantarctic Zone (SAZ), including the first isotopic compositions measured … for Si-depleted seawaters.

Variations of carbon remineralisation in the Southern Ocean illustrated by the Baxs proxy. Deep-Sea Research, 2005 (Ref: 11927)
Category 1: Peer-reviewed literature

We present water column profiles of excess particulate Ba (Baxs, an estimate of biogenic Ba from total particulate Ba … after small corrections for lithogenic Ba) along a transect in the Australian sector of the Southern Ocean from the … Subantarctic Zone (SAZ) to the Sea Ice Zone during spring…

Unexpected Changes to the Global Methane Budget over the Past 2000 Years. Science, 2005 (Ref: 12160)
Category 1: Peer-reviewed literature

We report a 2000-year Antarctic ice-core record of stable carbon isotope measurements in atmospheric methane (ä13CH4). Large ä13CH4 variations indicate that the methane budget varied unexpectedly during the late preindustrial Holocene (circa 0 to 1700 A.D.). During the first thousand years…

Predicting the distribution of crabeater seals Lobodon carcinophaga off east Antarctica during the breeding season. Marine Ecology Progress Series, 2005 (Ref: 12166)
Category 1: Peer-reviewed literature

ABSTRACT: Predictive species–environment models have numerous ecological and management applications, and can provide insight into the functional relationships between a species and its environment.

Polar ocean ecosystems in a changing world. Nature, 2005 (Ref: 12165)
Category 1: Peer-reviewed literature

Polar organisms have adapted their seasonal cycles to the dynamic interface between ice and water. This interface ranges from the micrometre-sized brine channels within sea ice to the planetary-scale advance and retreat of sea ice.
