Direct time-series observations of deep-sea biological activity are largely restricted to passive observations of benthic epifauna using unbaited time-lapse camera systems. However, highly mobile fauna such as scavenging fish are […]
Continuous flow analysis (CFA) is a well-established method to obtain information about impurity contents in ice cores as indicators of past changes in the climate system. A section of an […]
The recent intensification of the circumpolar circulation in the SH troposphere in summer and autumn has been attributed to external forcing such as stratospheric ozone depletion and greenhouse gas (GHG) […]
The deep sea surrounds Antarctica and constitutes about 80%, of the Southern Ocean (SO) seabed. Scientific cruises (e.g. ANDEEP) reveal that SO abyssal life can be highly abundant, rich and […]
The remote South Sandwich arc is an archipelago of small volcanic islands and seamounts entirely surrounded by deep water and about 600 km away from the closest island, South Georgia. […]
Swarms of Antarctic krill are frequently biased towards certain body sizes, sexes, maturities and physiological states. However, the mechanisms causing such biases remain unclear, with some speculating on differential responses […]
We present two Be-10 exposure ages from erratic boulders at Cape Adare, northem Victoria Land. The exposure ages obtained suggest that Cape Adare was covered by ice during the last […]
Dramatic changes (acceleration, thinning, and grounding-line retreat of major ice streams) in the Amundsen Sea sector of the West Antarctic Ice Sheet (WAIS) have been observed during the past two […]
Oceanographic data are presented from the eastern Bellingshausen Sea, representing the first near-contemporaneous sampling of conditions near both the northern and southern ice fronts of George VI Ice Shelf. Circumpolar […]
To date, little research has been carried out on pelagic gastropod molluscs (pteropods) in Southern Ocean ecosystems. However, recent predictions are that, due to acidification resulting from a business as […]
According to existing theory, electrons are accelerated up to ultra-relativistic energies(1) inside Jupiter’s magnetic field by betatron and Fermi processes as a result of radial diffusion towards the planet and […]
The cyclopoid copepod Oithona similis is highly abundant and ubiquitous in the marine epipelagic environment, yet rates of mortality in this species have rarely been quantified; indeed we are lacking […]
