Polarization of competition increases with latitude
Many organisms overlap in their use of resources in space and time. Where and when resources are restricted, species must compete for them. Living space, often a critical resource controlling […]

The Mid-Brunhes Event and West Antarctic Ice Sheet stability
Read more of: The Mid-Brunhes Event and West Antarctic Ice Sheet stabilityThe complex cyclical nature of Pleistocene climate, driven by the evolving orbital configuration of the Earth, is well known but not well understood. A major climatic transition took place at […]

Seasonal variations of gravity wave activity in the lower stratosphere over an Antarctic Peninsula station
Read more of: Seasonal variations of gravity wave activity in the lower stratosphere over an Antarctic Peninsula stationAn 8 year series of 965 high-resolution radiosonde soundings over Rothera (67 degrees S, 68 degrees W) on the Antarctic Peninsula are used to study gravity wave characteristics in the […]

A dispersive migration in the Atlantic Puffin and its implications for migratory navigation
Read more of: A dispersive migration in the Atlantic Puffin and its implications for migratory navigationNavigational control of avian migration is understood, largely from the study of terrestrial birds, to depend on either genetically or culturally inherited information. By tracking the individual migrations of Atlantic […]

Temperature signature of high latitude Atlantic boundary currents revealed by marine mammal-borne sensor and Argo data
Read more of: Temperature signature of high latitude Atlantic boundary currents revealed by marine mammal-borne sensor and Argo dataResults from the development and analysis of a novel temperature dataset for the high latitude North-West Atlantic are presented. The new 1 degrees gridded dataset (“ATLAS”) has been produced from […]

Data report: Dinoflagellate cyst analysis of Neogene sediments from Sites 1095 and 1096, Antarctic Peninsula continental rise
Read more of: Data report: Dinoflagellate cyst analysis of Neogene sediments from Sites 1095 and 1096, Antarctic Peninsula continental riseProtoperidiniacean dinoflagellate cysts were identified in 19 of 28 samples from two sites on the Antarctic Peninsula continental rise. Cysts are most common in the lower Pliocene and upper Miocene […]
