Turbulence measurements of the stable atmospheric boundary layer made at Halley station in Antarctica are presented. the interaction between small-scale turbulence and larger solitary wave disturbances is investigated. Spectral methods […]
The Raman microscopic analysis of a cryptoendolithic lichen community in sandstone from East Beacon Ridge, Victoria Land, Antarctica, is described for the first time. The Raman spectra from the crustal, […]
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 […]
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 […]
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 […]
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 […]
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 […]
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! […]
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 […]
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 […]
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 […]
