Model plasmasphere calculations for L-values near 2.5 at the longitude of Argentine Islands, Antarctica
Read more of: Model plasmasphere calculations for L-values near 2.5 at the longitude of Argentine Islands, AntarcticaA model of the terrestrial plasmasphere that includes an eccentric dipole geomagnetic field has been developed. Calculations are carried out for tubes of plasma at the longitude of Argentine Islands, […]

On the characteristics of eddies in the stable atmospheric boundary layer
Read more of: On the characteristics of eddies in the stable atmospheric boundary layerA discussion of the cross-spectral properties of eddies in the lowest 40 m of the nocturnal boundary layer is presented. The study involves the analysis of meteorological data collected by […]

The role of tectonics and eustasy in the evolution of a marginal basin: Cretaceous – Tertiary Larsen Basin, Antarctica
Read more of: The role of tectonics and eustasy in the evolution of a marginal basin: Cretaceous – Tertiary Larsen Basin, AntarcticaA 5–6 km thick, Cretaceous–Tertiary, marginal basin succession is exposed in the James Ross Island area (northern Antarctic Peninsula). Deep‐marine fan facies and slope‐apron facies (c. 2.5 km) are succeeded […]

Late Cretaceous stratigraphy and sedimentology of Cape Lamb, Vega Island, Antarctica
Read more of: Late Cretaceous stratigraphy and sedimentology of Cape Lamb, Vega Island, AntarcticaAn important new section for the latest Cretaceous marine sedimentary record is described from Cape Lamb, Vega Island, Antarctica. Some 480 m thick, it has been divided into three lithostratigraphic […]

Field relationships and stable isotope geochemistry of concretions from James Ross Island, Antarctica
Read more of: Field relationships and stable isotope geochemistry of concretions from James Ross Island, AntarcticaEarly diagenetic (precompactional) concretions are abundant throughout the Cretaceous-Tertiary Marambio Group Larsen Basin, Antarctica. Four distinct concretion types are recognised: (1) spherical-subspherical concretions: (2) sheet concretions; (3) fossil-nucleated concretions; and […]

Controls on the petrographic evolution of an active margin sedimentary sequence: the Larsen Basin, Antarctica
Read more of: Controls on the petrographic evolution of an active margin sedimentary sequence: the Larsen Basin, AntarcticaThe sedimentary fill of the Cretaceous-Tertiary Larsen Basin, located at the northern tip of the Antarctic Peninsula, records the evolution of the Antarctic Peninsula source terrain. Uplift, and the possible […]

An ionospheric signature of possible enhanced magnetic field merging on the dayside magnetopause
Read more of: An ionospheric signature of possible enhanced magnetic field merging on the dayside magnetopauseIdentifying the causative mechanisms at the magnetopause that produce a variety of transient plasma velocity signatures in the high latitude ionosphere is difficult. Correct identification is of fundamental importance in […]

Discrete taxa of saprotrophic fungi respire different ages of carbon from Antarctic soils
Read more of: Discrete taxa of saprotrophic fungi respire different ages of carbon from Antarctic soilsDifferent organic compounds have distinct residence times in soil and are degraded by specific taxa of saprotrophic fungi. It hence follows that specific fungal taxa should respire carbon of different […]
