The potential for Cretaceous coal in Antarctica
Cretaceous sediments in the Antarctic have yielded diverse fossil floras, and a few occurrences of thin coal have been described. Their presence illustrates that the climate was favorable for plant […]

Fostering behaviour and milk stealing in Antarctic fur seals
Read more of: Fostering behaviour and milk stealing in Antarctic fur sealsDuring the lactation period, female otariid seals alternate trips at sea to feed with visits ashore to nurse their pups. A female returning ashore must be able to recognize her […]

The effect of resolution on high latitude cloud track winds produced from AVHRR imagery
Read more of: The effect of resolution on high latitude cloud track winds produced from AVHRR imagerySequences of images from geostationary satellites have been used for some time to track clouds and so produce an estimate of the wind at cloud height (see/1/ and /2/). However, […]

The use of a simultaneous physical retrieval scheme for satellite derived atmospheric temperatures: Weddell Sea, Antarctica
Read more of: The use of a simultaneous physical retrieval scheme for satellite derived atmospheric temperatures: Weddell Sea, AntarcticaAtmospheric temperature retrievals obtained by a simultaneous physical scheme and a statistical scheme are compared using data gathered over the Weddell Sea, Antarctica during January 1986. Ground truth data were […]

Diving behavior and energetics during foraging cycles in king penguins
Read more of: Diving behavior and energetics during foraging cycles in king penguinsKing Penguins are the second largest of all diving birds and share with their congener, Emperor Penguins, breeding habits strikingly different from other penguins. Our purpose was to determine the […]

Effects of chronic crude oil exposure on early developmental stages of the Northern krill (Meganyctiphanes norvegica)
Read more of: Effects of chronic crude oil exposure on early developmental stages of the Northern krill (Meganyctiphanes norvegica)Rising oil and gas activities in northern high latitudes have led to an increased risk of petroleum pollution in these ecosystems. Further, seasonal high UV radiation at high latitudes may […]

Resolving the northern hemisphere source region for the long-distance dispersal event that gave rise to the South American endemic dung moss Tetraplodon fuegianus
Read more of: Resolving the northern hemisphere source region for the long-distance dispersal event that gave rise to the South American endemic dung moss Tetraplodon fuegianusPREMISE OF THE STUDY: American bipolar plant distributions characterize taxa at various taxonomic ranks but are most common in the bryophytes at infraspecific and infrageneric levels. A previous study on […]
