To capture the austral summer to winter transition in water mass properties over the southern Weddell Sea continental shelf and slope region, 19 Weddell seals were tagged with miniaturized conductivity–temperature–depth […]
We report simultaneous measurements of the O2(¹Δ) and O2(¹Σ) airglow volume emission rate profiles in the daytime mesosphere. We use these measurements to derive ozone concentrations separately from each airglow. […]
Previous work has demonstrated that exposure to an hour of bright light in the morning and the evening during the Polar winter has beneficial effects on circadian phase. This study […]
Magmatic rocks from the Antarctic Peninsula show marked variations in isotope composition, which reflect changes in the geodynamic evolution of the peninsula through time. Most Antarctic Peninsula granitoids formed as […]
SuperDARN observations from the interval 1330 UT to 1500 UT, 17 April 1996, are presented. During this interval, five radars covered 12 hours of magnetic local time on the dayside, […]
In polar regions, satellite microwave radiometry has not been successful in measuring the total water vapor (TWV) in the atmosphere. The difficulties faced in these regions arise from the very […]
Two hydrographic and δ18O transects across Fram Strait (Aug–Sept 1997, 1998) are used to examine freshwater contributions to the East Greenland Current (EGC). The EGC featured up to ∼16% meteoric […]
Retinal visual fields were determined using an ophthalmoscopic reflex technique in two seabird species of the family Procellariidae: white-chinned petrel Procellaria aequinoctialis and antarctic prion Pachyptila desolata. The binocular fields […]
Meteorological surface observations from the Antarctic Peninsula began in the mid-1940s. The most reliable long-term (~50 years) temperature record from this region has been obtained from Faraday station on the […]
The sub-antarctic mite genus Neohyadesia (Acari: Astigmata) is known from two described taxa: N. signyi from Signy Island (South Orkney Islands, South Atlantic Province), and a subspecies, N. s. punctulata […]
The meiofaunal tardigrades Milnesium cfr. tardigradum, Echiniscus sp., and Macrobiotus sp. were extracted from high altitude moss and volcanic scoria samples on sub-Antarctic Marion Island. Gut contents of mounted Milnesium […]
