Vertical geoelectric eld measurements at Vostok,Antarctica (78:5ºS ;107ºE;corrected geomagnetic latitude,83:4ºS) made during 1998 are compared with both Weimer (1996)and IZMEM (1994)model calculations of the solar-wind-induced, polar-cap potential di erences with respect to the station.
A popular hypothesis established in the 1980s proposed that the decline in whale populations in the Southern Ocean due to exploitation in the early to middle 20th century resulted in a ‘krill surplus’. It was proposed that other krill predators were released from a food-limited state…
Abstract Mixing models are used to determine diets … where the number of prey items are greater than one, however, the limitation of the linear mixing method is … the lack of a unique solution when the number of potential … sources is greater than the number (n) of isotopic … signatures +1.
Seasonal and interannual variations of the mixed layer properties in the Antarctic Zone (AZ) south of Tasmania are … described using7 WOCE/SR3 CTD sections and 8 years of summertime SURVOSTRAL XBT and thermosalinograph … measurements between Tasmania and Antarctica. The AZ…
Repeat hydrographic sections across the Antarctic Circumpolar Current (ACC) in Drake Passage are used to derive an empirical relationship between upper ocean … temperature and the baroclinic transport stream function.
The dissolved Barium (Bad) distribution in the whole … water column was examined along theWOCE SR3 line in the … Southern Ocean (Australian sector, late winter-spring 2001).
The sediment record of the fauna of Ace Lake, a saline meromictic lake in the Vestfold Hills, Antarctica, consists of copepod … eggs, spermatophores and exoskeletal fragments, rotifer and tintinnid loricae, and foraminiferal and folliculinid tests. The … relative abundance of these remains…
A GPS network has been installed to monitor vertical crustal movement … in the Lambert Glacier region, East Antarctica. The program … commenced in January 1998 with a solar-powered GPS system installed at … Beaver Lake.
Abstract Constructing realistic energy budgets for … Antarctic krill, Euphausia superba, is hampered by the … lack of data on the metabolic costs associated with … swimming. In this study respiration rates and pleopod … beating rates were measured at six current speeds.
Abstract. Due to the typical high atmospheric noise and low opacity, submillimeter observations … can be carried out only from sites with very high atmospheric stability and very … low precipitable water vapour content.
Abstract. The high plateau that covers half of the continent of Antarctica contains the best astronomical observing sites … on Earth. The infrared sky background is low, the precipitable water vapour is low, the sub-millimetre sky opacity is low, the winds are low…
ABSTRACT. The best ground-based astronomical sites in terms of telescope sensitivity at infrared and … submillimeter wavelengths are located on the Antarctic Plateau…
Geophysical inverse methods are used to calculate the basal motion of a glacier. They are applied to a one-dimensional forward model that can be linearized to make the analysis simpler. The inverse method finds a solution that fits the data within a given error.
