The propagation characteristics and path-integrated gain of Jovian lightning-generated whistlers are explored using the HOTRAY code. All waves are launched into the magnetosphere from just above the density peak in […]
Several species of nudibranch molluscs are abundant amongst the rich benthic hard substratum communities found close to the British Antarctic Survey base at Signy Island, in the Atlantic sector of […]
The nudibranch Charcotia granulosa, described originally by Vayssière (1906) from one specimen, was recollected for the first time at Signy Island, Antarctica. These three specimens allow a redescription of the […]
The seabed morphology beneath the ice shelf is dominated by a slope down towards the interior of the continent. Deep troughs, possibly glacially deepened, run beneath the eastern and weatern […]
Hinge zones accommodate the differential tidal movement between floating ice shelves, which move with the sea tide, and grounded ice sheets, which do not. Observations on Rutford Ice Stream and […]
Experimental data suggest that some igneous mafic inclusions are formed at the interface between underlying mafic magma and more silicic magma in a reservoir by a process of gas exsolution […]
Evidence of short-lived episodes of mid-Cretaceous deformation, metamorphism, uplift, and hiatus in sedimentation is widespread in the Lower Cretaceous rocks that bordered the Cretaceous Pacific basin. I present a model […]
ON page 412 of this issue1, Sugden and colleagues announce that glacier ice in the Dry valleys of East Antarctica seems to have survived for over 8 million years under […]
The synoptic origins of precipitation on the western side of the Antarctic Peninsula over the one year period March 1992 to February 1993 are investigated using meteorological observations, satellite imagery […]
