The northeast Antarctic Peninsula (NEAP) region is currently showing signs of significant environmental change, evidenced by acceleration of glacial retreat and collapse of both Larsen-A and -B ice shelves within […]
Previous work showed a near-continuous increase in stratospheric water vapour between the 1950s and 1990s from a variety of instruments, without recourse to fits between instruments. We reassess the trend […]
Rapid, or abrupt, climate change is regarded as a change in the climate system to a new state following the crossing of a threshold. It generally occurs at a rate […]
In avian species that have evolved life-history strategies wherein molt and breeding overlap, there are potential conflicts between the regulatory roles of baseline prolactin and corticosterone in parental care (positive) […]
Global warming is a reality and its effects have been widely studied. However, the consequences for marine invertebrates remain poorly understood. Thus, the present study proposed to evaluate the effect […]
The supply of nutrients to the low-latitude thermocline is largely controlled by intermediate- depth waters formed at the surface in the high southern latitudes. Silicic acid is an essential macronutrient […]
The results of a combined geophysical and geochemical research programme on Deception Island, an active volcano at 62degrees43’S, 60degrees57’W in Bransfield Strait (Antarctica), are presented. Ultrahigh-resolution acoustic data obtained with […]
A new species of the synallactid sea cucumber genus Pseudostichopus is described, P. aemaulatus sp. nov., based on genetic (DNA sequences of the mitochondrial gene Cytochrome Oxidase I [COI] gene) […]
It has been suggested that whistler mode chorus waves play a role in the acceleration and loss of radiation belt electrons during geomagnetic storms. In a previous statistical study of […]
[1] It has been suggested that whistler mode chorus waves play a role in acceleration and loss of radiation belt electrons during geomagnetic storms. In this paper we present data […]
[1] We present a model for the growth of frazil ice crystals and their accumulation as marine ice at the base of Antarctic ice shelves. The model describes the flow […]
Observations with a Meteor radar operating at 32.55 MHz have been used to derive daily atmospheric temperature data for an altitude of 90 km at mid-latitudes during November 1999 until […]
