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 […]
How true is the statement: “The camera never lies”? Trick photography has a long and varied history, and good fakes are extremely difficult to refute. Now computer software makes it […]
Three new non-indigenous springtail species are recorded in recent collections made on Deception Island, South Shetland Islands, maritime Antarctic: Deuteraphorura (Deuteraphorura) cebennaria (Gisin) (Collembola: Onychiuridae), Mesaphorura macrochaeta Rusek (Tullbergiidae), and […]
