The influence of ice on polar nearshore benthos
Polar benthic communities are subject to a range of disturbance levels from a variety of sources, principal amongst which is ice. This occurs in four main forms: the ice-foot, ice […]

Do life patterns differ between two Scotia Arc localities? A preliminary investigation of three erect Antarctic bryozoan species
Read more of: Do life patterns differ between two Scotia Arc localities? A preliminary investigation of three erect Antarctic bryozoan speciesErect bryozoans are extremely abundant and diverse in polar waters and individual species may span a wide range in latitude and bathymetry. A number of aspects of lifestyle, including polypide […]

Dinosaur energetics: setting the bounds on feasible physiologies and ecologies
Read more of: Dinosaur energetics: setting the bounds on feasible physiologies and ecologiesThe metabolic status of dinosaurs has long been debated but remains unresolved as no consistent picture has emerged from a range of anatomical and isotopic evidence. Quantitative analysis of dinosaur […]

Antarctic glacial history from numerical models and continental margin sediments
Read more of: Antarctic glacial history from numerical models and continental margin sedimentsThe climate record of glacially transported sediments in prograded wedges around the Antarctic outer continental shelf, and their derivatives in continental rise drifts, may be combined to produce an Antarctic […]

Falkland Plateau evolution and a mobile southernmost South America
Read more of: Falkland Plateau evolution and a mobile southernmost South AmericaAssessment of southwest Gondwana break-up and its implications for regional hydrocarbon prospectivity must now take into account the origin of the southeast margin of the Falkland Islands as a volcanic […]

Evidence for a volcanic rifted margin and oceanic crustal structure for the Falkland Plateau Basin
Read more of: Evidence for a volcanic rifted margin and oceanic crustal structure for the Falkland Plateau BasinMarine geophysical data from the western Falkland Plateau show strongly lineated magnetic anomalies and a coincident linear gravity high that identify the southeastern margin of a Falkland Islands block as […]

Identification of molecular and physiological responses to chronic environmental challenge in an invasive species: the Pacific oyster, Crassostrea gigas
Read more of: Identification of molecular and physiological responses to chronic environmental challenge in an invasive species: the Pacific oyster, Crassostrea gigasUnderstanding the environmental responses of an invasive species is critical in predicting how ecosystem composition may be transformed in the future, especially under climate change. In this study, Crassostrea gigas, […]

Vertebrate records in polar sediments: Biological responses to past climate change and human activities
Read more of: Vertebrate records in polar sediments: Biological responses to past climate change and human activitiesBiological responses to climate and environmental changes in remote polar regions are of increasing interest in global change research. Terrestrial and marine polar ecosystems have suffered from impacts of both […]

Solution geochemistry and behaviour of major and trace elements during summer in a moss community at Edmonson Point, Victoria Land, Antarctica
Read more of: Solution geochemistry and behaviour of major and trace elements during summer in a moss community at Edmonson Point, Victoria Land, AntarcticaPhysical and chemical characteristics and solution geochemistry of major and trace elements were investigated in an area of volcanic soil colonized by mosses at Edmonson Point (central Victoria Land) during […]

NGRIP CH4 concentration from 120 to 10 kyr before present and its relation to a δ15N temperature reconstruction from the same ice core
Read more of: NGRIP CH4 concentration from 120 to 10 kyr before present and its relation to a δ15N temperature reconstruction from the same ice coreDuring the last glacial cycle, Greenland temperature showed many rapid temperature variations, the so called Dansgaard-Oeschger (DO) events. The past atmospheric methane concentration closely followed these temperature variations, which implies […]
