1. Ground observations and possible source regions of two types of Pc 1-2 micropulsations at very high latitudes

   We have used 1-year’s data from the recently installed Magnetometer Array for Cusp and Cleft Studies (MACCS) in Arctic Canada and from two stations of the developing “conjugate” array of […]

3. Taxonomic investigations of palynomorphs from the Byers group (Upper Jurassic‐Lower Cretaceous), Livingston and Snow islands, Antarctic Peninsula

   Two new palynomorph taxa are described, and several existing taxa are discussed from the Upper Jurassic‐Lower Cretaceous Byers Group of Livingston and Snow islands, South Shetland Islands, Antarctic Peninsula. Oligosphaeridium […]

4. Christensenia , a new terrestrial enchytraeid genus from Antarctica

   Christensenia gen. nov., C. blocki sp. nov., is described from Signy Island, South Orkney Islands, maritime Antarctic. The new species is identical with specimens that Stephenson (1932) determined as Marionina […]

5. Jurassic belemnite distribution patterns: implications of new data from Antarctica and Argentina

   Belemnites are nektopelagic cephalopods which developed a widespread pattern of distribution in the Jurassic, and most authors have accepted that their centre of origin was Europe. Available data suggest that […]

6. Oligocene and Pliocene interglacial events in the Antarctic Peninsula dated using strontium isotope stratigraphy

   Strontium isotope stratigraphy is used to date two interglacial-marine deposits in the Antarctic Peninsula region. On King George Island, interglacial pectinid-rich sediments in the Low Head Member of the Polonez […]

7. Interspecific variation in respiratory and photosynthetic parameters in Antarctic bryophytes

   Rates of carbon flux in 14 species of Antarctic bryophytes were measured under controlled conditions using an infra-red gas analysis system. The results were used to produce estimates of mode! […]

8. Effects of short-term dehydration and rehydration on photosynthesis and respiration by Antarctic bryophytes

   The hypothesis that rates of carbon exchange and recovery following dehydration by Antarctic bryophytes are related to habitat water availability was investigated. Carbon fixation was measured using an infra-red gas […]

9. Effects of physical factors on photosynthesis by the Antarctic liverwort Marchantia berteroana

   Effects of irradiance, temperature and water availability on respiration and photosynthesis in a maritime Antarctic liverwort, Marchantia berteroana, were investigated. Carbon dioxide exchange was measured using an infra-red gas analysis […]

10. Effects of continuous and repeated dehydration on carbon fixation by bryophytes from the maritime Antarctic

    The effects of dehydration and rehydration on carbon exchange in 14 bryophytes from the maritime Antarctic were investigated using an infra-red gas analysis system. Continuous long-term (1–12 months) and repeated […]

11. Comparisons of the biology of the intertidal Subantarctic limpets Nacella concinna and Kerguelenella lateralis

    Two limpet species occur intertidally on subantarctic South Georgia, the patellid Nacella concinna and the siphonarlid Kerguelenella lateralis. N. concinna is confined to the lower shore close to LWS; K. […]

12. Gondwanian age dextral transpression and spatial kinematic partitioning within the Heritage Range, Ellsworth Mountains, West Antarctica

    The Ellsworth Mountains, West Antarctica, consist of two mountain ranges; the Sentinel, and Heritage ranges. The more southerly Heritage Range is composed of a lower Paleozoic sedimentary and volcanic rock […]
