Graphical methods for the exploration of ecological databases … Ben Raymond, Lee Belbin, Jonathan Stark … Scientific data repositories are becoming increasingly characterised by large data sets stored in web-accessible, structured databases.
Ground layer Adaptive Optics (GLAO) is a new variant of adaptive optics that aims at correcting the seeing … over a wide field of view by conjugating the deformable mirror to the boundary layer altitude.
Geophysical inverse methods are used to calculate the basal motion of a glacier. They are applied to a one-dimensional forward model that can be linearized to make the analysis simpler. The inverse method finds a solution that fits the data within a given error.
The diet of grey-headed albatrosses at Diego Ramírez was analysed and compared to that of the … sympatric black-browed albatross. Diet composition was inferred from an analysis of prey hard parts present … in 103 chick regurgitates obtained during breeding seasons 2000, 2001 and 2002.
Embryos released by gravid females of Antarctic krill (Euphausia superba Dana) at the Port of Nagoya Public … Aquarium, Japan were incubated in the laboratory to determine the development time and hatching success of … embryos at 2.1, 1.7, 1.2, 0.6, 0.1, 0.8 and 2.4C.
Chile is a fishery country with important artisanal and industrial longline fleets during the last 30 year. Main fishing resources in southern Chile are Patagonian toothfish, Ling and Austral hake. All these fisheries are suspected to have high seabird mortality.
As part of a general survey of the biodiversity and inherent ecophysiology of bacteria associated with coastal Antarctic sea-ice diatom assemblages, eight strains were identified by 16S rRNA sequence analysis as belonging to the genus Colwellia. The isolates were non-pigmented…
Species of the genus Pseudoalteromonas are frequently isolated from marine ecosystems and appear to be particularly abundant in Antarctic coastal waters.
A group of pigmented, psychrophilic, strictly aerobic chemoheterotrophs isolated from sea-ice cores collected from coastal areas of eastern Antarctica was found to represent a novel 16S rRNA lineage within the gamma subclass of the Proteobacteria, adjacent to the genus Alteromonas.
A group of sea-ice-derived psychrophilic bacterial strains possessing the unusual ability to synthesize the polyunsaturated fatty acids eicosapentaenoic acid (20:5w3) and arachidonic acid (20:4w6) belong to the Family Flavobacteriaceae (Flexibacter–Bacteroides–Flavobacterium phylum)…
Fresh water lakes are found in basement rock basins in the Larsemann Hills, East Antarctica, during the summer months. These lakes constitute a relatively simple natural laboratory to investigate the effects of recent and well-documented anthropogenic impact on a pristine environment.
In order to improve our understanding of the January losses of ozone in the Arctic vortex two ozonesondes Match campaigns are scheduled within the project "Quantitative Understanding of Ozone losses by Bipolar Investigations" (QUOBI).
