Changes in the metastability of the Southern Hemisphere 500-hPa circulation are examined using both cluster analysis techniques and split-flow blocking indices. The cluster methodology is a purely data-driven approach for […]
The lower limb of the Atlantic overturning circulation is renewed by dense waters from the Southern Ocean, a substantial portion of which flow through the Scotia Sea. We report dense […]
Sea ice variability in the Southern Ocean has a complex spatio-temporal structure. In a global warming context, the Antarctic sea ice cover has slightly expanded over the recent decades. This […]
Inter-ice stream areas cover significant portions of Antarctica’s formerly glaciated shelves, but have been largely neglected in past geological studies because of overprinting by iceberg scours. Here, we present results […]
To probe the spatial extent of tropospheric ozone depletion events during Antarctic spring, a network of 10 autonomous ozone monitors was established around the Dronning Maud Land sector of Antarctica […]
Strong and predictable environmental variability can reward flexible behaviors among animals. We used long-term records of activity data that cover several lunar cycles to investigate whether behavior at-sea of swallow-tailed […]
This map presents the final outputs from the BEDMAp2 project as a double-sided poster map.It shows the new BEDMAP datasets of Antarctic ice thickness, surface height and bed elevation mapped […]
Measurements of Last Interglacial stable water isotopes in ice cores show that central Greenland d18O increased by at least 3& compared to present day. Attempting to quantify the Greenland interglacial […]
The GENTOO project aims to investigate the potential for undersea gliders to make high resolution temporal and spatial biological and physical observations of ocean currents and krill distribution to the […]
There are few observations of speciated inorganic bromine in polar regions against which to test current theory. Here we report the first high temporal resolution measurements of Br2, BrCl and […]
We studied the long-distance migration of Lesser Black-backed Gulls Larus fuscus fuscus breeding in northern Norway along their eastern flyway using geolocators in 2009 and 2010. The majority of birds […]
