A re-compilation of magnetic data in the Weddell Sea is presented and compared with the gravity field recently derived from retracked satellite altimetry. The previously informally named ‘Anomaly-T,’ an cast-west […]
Bransfield Strait is a Quaternary, ensialic back arc basin at the transition from rifting to spreading. Fresh volcanic rocks occur on numerous submarine features distributed along the rift axis, including […]
Detailed chemical analysis of the 122 m, relatively high-altitude and lowmelt Lomonosovfonna ice core provides the best-dated record of nitrate from Svalbard. A very significant non-linear trend present in the […]
[1] We have analyzed in detail the auroral bulge evolution during the expansion phase of an isolated substorm, which was observed by the UV imager aboard the Akebono satellite. It […]
[1] We have analyzed in detail the evolution of nightside auroral activities and ionospheric convection during the growth phase of an isolated substorm. The following three characteristic auroral activities were […]
Knowledge of the late Miocene-Pliocene climate of West Antarctica, recorded by sedimentary units within the James Ross Island Volcanic Group, is still fragmentary. Late Miocene glacio-marine deposits at the base […]
A total of 11,500 line km of aerogravity data have been used to construct an free-air gravity anomaly map for the Antarctic region that may contain the microplate boundary between […]
Acquisition and transfer of algae from distant polar locations to research facilities in the northern hemisphere may take several months, at which point the algae may be non-viable and in […]
Muscle growth was investigated in Harpagifer species with sub-Antarctic (Harpagifer bispinis, environmental temperature (ET) 4-11°C) and Antarctic (Harpagifer antarcticus, ET -1.5 to +1°C) distributions. The trunk musculature of 1 d-old […]
The Pacific margin of the Antarctic Peninsula to the southwest of the Hero Fracture Zone (HFZ) is a former subducting margin which became inactive following the arrival of ridge crest […]
[1] An isopycnic coordinate ocean circulation model has been applied to the southern Weddell Sea, including the cavity beneath Filchner-Ronne Ice Shelf, with the aim of investigating the buoyancy-forced circulation […]
