Mechanical weathering rates on Signy Island, maritime Antarctic
Read more of: Mechanical weathering rates on Signy Island, maritime AntarcticBy means of re‐evaluating a number of properties of rock tablets left in the field for varying time periods, an estimation of rock breakdown rates is attained. From data obtained […]

Tests of Antarctic soils for insect parasitic nematodes
Read more of: Tests of Antarctic soils for insect parasitic nematodesNematodes of the families Heterorhabditidae and Steinernematidae are obligate parasites of a wide range of insects (Poinar 1979). The third stage juvenile of these nematodes is a non-feeding infective form […]

Interpretation of reconnaissance gravity and aeromagnetic surveys of the Antarctic Peninsula
Read more of: Interpretation of reconnaissance gravity and aeromagnetic surveys of the Antarctic PeninsulaTwo‐dimensional models are presented for the crustal structure of the Antarctic Peninsula, a Mesozoic‐Cenozoic magmatic arc on the southeast Pacific margin. The models are constrained by measured rock properties. The […]

Modelling the response of the thermosphere and ionosphere to geomagnetic storms: Effects of a mid-latitude heat source
Read more of: Modelling the response of the thermosphere and ionosphere to geomagnetic storms: Effects of a mid-latitude heat sourceThe UCL-Sheffield coupled thermosphere/ionosphere model has been used to assess the consequences of a heat source from ring current ion precipitation during a geomagnetic storm. Such a source might in […]

Target strengths of Antarctic krill (Euphausia superba) at 38 and 120 kHz
Read more of: Target strengths of Antarctic krill (Euphausia superba) at 38 and 120 kHzEncaged aggregations of live krill in good to pristine condition have been ensonified at 38 and 120 kHz. Concurrent underwater television observations of behavior resemble those made by underwater divers […]
