The temporal and spatial behaviour of the ionospheric parameters foF2 and h’F during isolated substorms are examined using data from ionospheric stations distributed across Europe and western Asia. The main […]
Extensive sponge assemblages are found in a number of habitats at Lough Hyne Marine Nature Reserve. These habitats are unusual in experiencing a range of environmental conditions, even though they […]
Results from 15 years of work on glacier-bed mapping by radio-echo soundings on Finsteraar-, Lauteraar- and Unteraargletscher, Switzerland, are summarized, and a new and greatly improved map of the ice-thickness […]
Determining the microphysical location of impurities in natural ice from the polar regions is necessary for understanding the physical properties of ice and for assuring the integrity of ice core […]
[1] Interpretation of the chemical layers measured in ice cores requires knowledge of processes occurring after their deposition on the ice sheet. We present evidence for the diffusion of soluble […]
Ridges have been observed at the bonds between sintering snow grains. Images collected using the scanning electron microscope (SEM) and x-ray analysis of Antarctic snow are presented. These indicate the […]
On polar shores, as at lower latitude, intense battles for space ensue on boulders but the high wind, wave and ice disturbance make the colonisation race a short one in […]
In just 4 decades, marine litter has become abundant in northern oceans and seas and is increasing on even remote Southern Ocean island shores. The Southern Ocean was thought to […]
The waters surrounding Antarctica are amongst the most isolated large areas of continental shelf, cut off for about 15 to 30 million yr by both deep water and the oceanographic […]
To see the ‘big pictures’, it seems increasingly clear that experimental design, data collection and analyses of ecological investigation need to be at multiple scales. This causes problems with data […]
Limacina helicina antarctica is a common part of the Southern Ocean zooplankton community but little is known about its life cycle. Here we determine the population structure and standing stock […]
Many calanoid copepods inhabiting high latitude environments overwinter at depth in the water column in a state of diapause and the large wax ester reserves that they contain are central […]
