Antarctic subglacial lakes are thought to be extreme habitats for microbial life and may contain important records of ice sheet history and climate change within their lake floor sediments. To […]
A 181 m deep ice core drilled in 1994/95 on the south dome of Berkner Island, Antarctica, was analyzed for stable isotopes, major ions and microparticle concentrations. Samples for ion […]
The variability of size and source of significant precipitation events were studied at an Antarctic ice core drilling site: Dolleman Island (DI). located on the eastern coast of the Antarctic […]
An extended high-resolution ice core record of dust deposition over the past 60 ka from Dome C, Antarctica, is presented. The data are in conflict with the idea that changes […]
Measurements of total ozone in Antarctica during early winter show an increase, consistent with the observed descent of stratospheric air and the convergence that accompanies descent. Measurements in the vortex […]
Twenty years ago there were large disagreements between instruments measuring stratospheric H2O and NO2, and there were no reliable long-term records. Now, there is greatly improved agreement between techniques, there […]
Descent of air from stratosphere to troposphere in Antarctic winter is proposed to be feasible, because of forcing from above by subsidence plus wave-breaking, together with suction from below to […]
Jodie Dunn is to be commended for her entertaining and well-researched article in Weather (Dunn 2004). However, some of the arguments deserve to be amplified, and they demonstrate interesting and […]
While much remains unknown about seamount communities, scientific evidence suggests that high seas bottom trawling may have significant and irreversible impacts on the diversity and ecology of seamounts and other […]
Deep-sea coral reefs live in the cold, dark waters of the oceans but like shallow water tropical coral reefs they have a distinct, diverse and sometimes highly endemic associated animal […]
It has been suggested that whistler-induced electron precipitation (WEP) may be the most significant inner radiation belt loss process for some electron energy ranges. One area of uncertainty lies in […]
