In this paper we examine the claim that the power law distribution of burst lifetimes in the AE index is evidence that the magnetosphere is a Self‐Organized Critical (SOC) system. […]
Magnetospheric cavity modes can decay through various loss processes. Energy leakage across the magnetopause is one such process that is commonly neglected. Here we consider what the actual effect of […]
A recently published analysis of slant columns of NO2 observed at twilight at 45°S has identified trends of about 5%/decade between 1980 and 1998. This is twice the trend in […]
The Oligocene to Quaternary succession encountered in CRP-2/2A is divided into twelve recurrent lithofacies (some of which have been subdivided further), reflecting a range of marine, glacimarine and possibly subglacial […]
Interpretation of an airborne magnetic data compilation containing a key, new survey, together with re-tracked satellite gravity data from the WeddellSeaembayment (WSE), West Antarctica, suggests Rift–Rift–Rift triplejunction formation at the […]
The precarious condition of the world’s fisheries is making ever-greater demands of the scientific assessment of fish stocks. Traditional assessments that rely on commercial catch statistics can have major shortcomings1 […]
Environmental seasonality is a critical factor in structuring polar marine ecosystems. The extensive data now available on the lipids of Arctic and Antarctic euphausiids show that all species are characterised […]
Silicified conifer woods are very common in the mid-Cretaceous (LateAlbian, 100 Ma) Triton Point Member of the Neptune Glacier Formation (Fossil Bluff Group), SE AlexanderIsland, Antarctica. These occur as up […]
Growth rings in modern conifer woods were quantitatively analysed to investigate the relationship between leaflongevity and the markedness of the growth ring boundary. Five conifer species exhibiting a wide range […]
A method is outlined in which woods produced by deciduous and evergreen coniferopsids may be distinguished from one another on the basis of a quantitative analysis of growth ring anatomy. […]
Spawning by Antarctic fish is generally considered to be seasonal and restricted to a brief period during the autumn and winter. Arising from this it has been assumed that the […]
