Marine geophysical studies of the South Orkney microcontinent show two intersecting tectonic fabrics of different age. The older fabric is oriented E-W, and represents the magmatic arc and fore-arc created […]
Following the cessation of subduction along the Antarctic Peninsula, there was a change in the character of the magmatism from calc-alkaline to alkaline. A Miocene-Pliocene suite of basanites, tephrites and […]
The Southern Coastal Batholith of central Chile is mainly composed of calc-alkaline granitoids of Late Carboniferous to Permian age. There is no clear evidence of the existence of older plutonic […]
The filamentous chlorophyte Spirogyra forms a mat covering extensive areas of Spirogyra Lake, a small, shallow, Antarctic lake. It has an annual growth pattern, with a maximum standing crop of […]
Place names in the Hughes Bay area, Danco Coast, Antarctica well illustrate naming problems that give rise to confusion or ambiguity. This note shows the origins of conflicting place names, […]
Arctic heat and freshwater budgets are highly sensitive to volume transports through the Arctic‐Subarctic straits. Here we study the interconnectivity of volume transports through Arctic straits in three models; two […]
The Antarctic Peninsula (AP) is a region of special climatological interest. The late twentieth century has been a period of warming surface temperatures, enhanced mass loss from melting glaciers and […]
This study investigates the interhemispheric nature of polar cap auroras via ultraviolet imaging, combined with particle data, to determine whether they occur on open or closed field lines. Data from […]
Most of the exploited fish stocks in the North Sea are also used as a food supply by a number of seal species; the same is true for some fish […]
