Distribution of soluble impurities in cold glacial ice
Read more of: Distribution of soluble impurities in cold glacial iceUnderstanding the microstructure of ice underpins the interpretation of ice-core measurements and many ice-sheet properties. A detailed study of polar snow and ice using scanning electron microscope (SEM) and X-ray […]

Polar pedunculate barnacles piggy-back on pycnogona, penguins, pinniped seals and plastics
Read more of: Polar pedunculate barnacles piggy-back on pycnogona, penguins, pinniped seals and plasticsThere is much concern about the potential for invasive species to enter the only marine region left with no known exotics – the Southern Ocean. Attention has focused on planktonic […]

Variability of competition at scales of 10(1), 10(3), 10(5), and 10(6) m: encrusting arctic community patterns
Read more of: Variability of competition at scales of 10(1), 10(3), 10(5), and 10(6) m: encrusting arctic community patternsVariability in interference competition was studied in benthic marine communities of the arctic and subarctic Atlantic intertidal and shallow subtidal zones. We sampled multiple square-metre quadrats at distances of 10(1). […]

Natural and plastic flotsam strading in the Indian Ocean
Read more of: Natural and plastic flotsam strading in the Indian OceanOver long periods of geological time the island rich NE Indian Ocean region has developed to be a region of high marine species richness but in the last few decades […]

Moving beyond the IGY: the electronic Geophysical Year (eGY) concept
Read more of: Moving beyond the IGY: the electronic Geophysical Year (eGY) conceptThe International Geophysical Year (1957–1958) was inspired by the realization that much better and more complete information was needed about the Earth and geospace to understandand manage the complete terrestrial […]

A miniature daylight level and activity data recorder for tracking animals over long periods
Read more of: A miniature daylight level and activity data recorder for tracking animals over long periodsThe device has a sensor that periodically measures and records the ambient light level. Following retrieval of the device, the light level records are converted into latitudes and longitudes, which […]

Scale-dependent variation in competitive ability among encrusting Arctic species
Read more of: Scale-dependent variation in competitive ability among encrusting Arctic speciesFinding evidence for climate change in the sea has been less easy than on land. As ice-loading of nearshore waters (through ice sheet collapses) seems a most likely signal of […]

Long-term decline in krill stock and increase in salps within the Southern Ocean
Read more of: Long-term decline in krill stock and increase in salps within the Southern OceanAntarctic krill ( Euphausia superba) and salps ( mainly Salpa thompsoni) are major grazers in the Southern Ocean(1-4), and krill support commercial fisheries(5). Their density distributions(1,3,4,6) have been described in […]

Diet of grey-headed albatrosses at the Diego Ramirez Islands, Chile: ecological implications
Read more of: Diet of grey-headed albatrosses at the Diego Ramirez Islands, Chile: ecological implicationsThe diet of grey-headed albatrosses at Diego Ramirez was analysed and compared to that of the sympatric black-browed albatross. Diet composition was inferred from an analysis of prey hard parts […]

A modelling study of the response of Hatherton Glacier to Ross Ice Sheet grounding line retreat
Read more of: A modelling study of the response of Hatherton Glacier to Ross Ice Sheet grounding line retreatThe late Holocene retreat of the West Antarctic ice sheet is crucial information for assessing its current dynamics. However, data from this period for parts of the ice sheet where […]

The seasonal cycle of stratosphere-troposphere coupling at southern high latitudes associated with the semi-annual oscillation in sea-level pressure
Read more of: The seasonal cycle of stratosphere-troposphere coupling at southern high latitudes associated with the semi-annual oscillation in sea-level pressureThe semi-annual oscillation (SAO) in sea-level pressure at high southern latitudes is the consequence of a twice-yearly contraction (and strengthening) and expansion (and weakening) of the storm track between 50 […]
