1. IMF-driven change to the Antarctic tropospheric temperature due to the global atmospheric electric circuit

   We use National Centers for Environmental Prediction (NCEP)/National Center for Atmospheric Research (NCAR) reanalysis data to investigate the Antarctic mean tropospheric temperature anomaly associated with changes in the dawn-dusk component […]

2. Robust wavebuoys for the marginal ice zone: Experiences from a large persistent array in the Beaufort Sea

   An array of novel directional wavebuoys was designed and deployed into the Beaufort Sea ice cover in March 2014, as part of the Office of Naval Research Marginal Ice Zone […]

3. Warming by 1°C drives species and assemblage level responses in Antarctica’s marine shallows

   Forecasting assemblage-level responses to climate change remains one of the greatest challenges in global ecology [1 , 2 ]. Data from the marine realm are limited because they largely come […]

4. The Ross Sea Dipole – temperature, snow accumulation and sea ice variability in the Ross Sea region, Antarctica, over the past 2700 Years

   High-resolution, well-dated climate archives provide an opportunity to investigate the dynamic interactions of climate patterns relevant for future projections. Here, we present data from a new, annually-dated ice core record […]

5. Climate instability during the last interglacial period recorded in the GRIP ice core

   Isotope and chemical analyses of the GRIP ice core from Summit, central Greenland, reveal that climate in Greenland during the last interglacial period was characterized by a series of severe […]

6. Satellite radar interferometry for monitoring ice sheet motion: application to an Antarctic ice stream

   Satellite radar interferometry (SRI) provides a sensitive means of monitoring the flow velocities and grounding-line positions of ice streams, which are indicators of response of the ice sheets to climatic […]

7. Microbial community dynamics and enzyme activity of an Antarctic fellfield soil during the austral summer

   Microbial and enzymatic activities were measured during the 49-day austral summer of 1991 in two fellfield soil polygons (WW-5 and WW-18) at Signy I. In 0-2.5 cm cores, microbial counts […]

8. Late Cretaceous and Paleocene decapod crustaceans from James Ross Basin, Antarctic Peninsula

   Seventeen species of decapod crustaceans have been described from Campanian through Paleocene rocks in the Santa Marta, López de Bertodano, and Sobral Formations of the James Ross Basin, Antarctica. Of […]

9. Comparison of krill (Euphausia superba) density estimates using 38 and 120 kHz echosounders

   A series of observations, using a dual-frequency calibrated echosounder operating at 38 and 120 kHz, of a patch of Euphausia superba close to South Georgia in 1986 is described. Sea […]

10. Observations on life cycle and feeding ecology of two recently introduced predatory beetle species at South Georgia, sub-Antarctic

    On South Georgia, two recently introduced species of predatory beetle,Oopterus soledadinus andTrechisibus antarcticus (Coleoptera, Carabidae), were studied in the period November 1991–April 1992. The study area comprised the coastal area […]

12. Signatures of dayside solar wind/magnetosphere/ionosphere coupling as revealed by the PACE HF radars and associated experiments

    The nature of the coupling between the solar wind and magnetosphere on the dayside of the Earth, and the response of the ionosphere to this coupling are currently topics of […]
