Horizontal acceleration corrections in airborne gravimetry
Read more of: Horizontal acceleration corrections in airborne gravimetryThe stabilized platforms used in marine and airborne gravimeters behave like damped long‐period pendulums. When subjected to horizontal accelerations they tilt, resulting in gravimeter reading errors. The amount of tilt […]

The phase relationships of the ionospheric signatures of Pc1 geomagnetic pulsations
Read more of: The phase relationships of the ionospheric signatures of Pc1 geomagnetic pulsationsIn this study we consider the phase relationships between the oscillations of various ionospheric signatures associated with Pcl geomagnetic pulsations. Investigations using a simple analytical method and a numerical model, […]

Geodynamic evolution of the Antarctic Peninsula during Mesozoic times and its bearing on Weddell Sea history
Read more of: Geodynamic evolution of the Antarctic Peninsula during Mesozoic times and its bearing on Weddell Sea historyThis review of the tectonic evolution of the Antarctic Peninsula during Mesozoic times highlights four main events; (1) Late Triassic-Late Jurassic extension, (2) Late Jurassic-Early Cretaceous dextral transpression, (3) Early […]

Early Paleozoic sedimentation, magmatism, and deformation in the Pensacola Mountains, Antarctica: The significance of the Ross orogeny
Read more of: Early Paleozoic sedimentation, magmatism, and deformation in the Pensacola Mountains, Antarctica: The significance of the Ross orogenyCombined sedimentological, structural, and geochemical studies of a lower Paleozoic succession within the Pensacola Mountains, Antarctica, suggest that it probably formed in a foreland basin setting during the Ross-Delamerian orogen, […]

Microplates and mantle plumes in Antarctica
Read more of: Microplates and mantle plumes in AntarcticaThe main geological characteristics of five crustal blocks within West Antarctica are summarized in this review. At least some of these blocks existed as Mesozoic microplates and their original, palaeoposition […]

Oribatid mites (Acari: Oribatida) of the Falkland Islands, South Atlantic and their zoogeographical relationships
Read more of: Oribatid mites (Acari: Oribatida) of the Falkland Islands, South Atlantic and their zoogeographical relationshipsA total of 21 species of oribatid mites (Acari: Oribatida) are recorded from heat-extracted samples of soil and plant material collected in the Falkland Is., South Atlantic. Previous records of […]

Ocean tides under the Filchner-Ronne Ice Shelf, Antarctica
Read more of: Ocean tides under the Filchner-Ronne Ice Shelf, AntarcticaA depth-averaged finite-difference numerical model has been used to make a preliminary study of the tides under the Filchner‐Ronne Ice Shelf. Open boundary conditions were specified using the global ocean […]
