Granulometry of pebble beach ridges in Fort Williams Point, Greenwich Island, Antarctic Peninsula; a possible result from Holocene climate fluctuations
We present a granulometric study of emerged pebble beach ridges in the Fort Williams Point, Greenwich Island, Antarctic Peninsula. We studied 8 beach ridges from the shore up to 13.5 m above current sea level. The beach ridges are made of volcanic material from the surrounding relief, but also include glacially transported gneiss and granodiorite pebble and cobble. Based on granulometric distri...
متن کاملNonclassical rotational behavior at the vicinity of the lamda point
The rotational property of a quantum liquid at the vicinity of the lamda point Tλ is examined. In a liquid helium 4, shear viscosity shows a slight decrease just above Tλ. We suppose that under the strong influence of Bose statistics, the coherent many-body wave function grows to an intermediate size between a macroscopic and a microscopic size just above Tλ, and suppress the shear viscosity. W...
متن کاملFirst record of an Adélie penguin at sub-Antarctic Marion island
Background: The sub-Antarctic Prince Edward Archipelago (46°53’S, 37°52’E), consisting of Marion and Prince Edward islands, is situated in the Indian sector of the Southern Ocean, approximately 2 600 km away from the closest Adélie penguin (Pygoscelis adeliae) breeding locality, Bouvet Island (54°25’S; 3°22’E). Methods: Two opportunistic sightings of an Adélie penguin at Marion Island on 28 Oct...
متن کاملAt‐sea distribution and habitat use in king penguins at sub‐Antarctic Marion Island
King penguins make up the bulk of avian biomass on a number of sub-Antarctic islands where they have a large functional effect on terrestrial and marine ecosystems. The same applies at Marion Island where a substantial proportion of the world population breeds. In spite of their obvious ecological importance, the at-sea distribution and behavior of this population has until recently remained en...
متن کاملClimate Trends at Macquarie Island and Expectations of Future Climate Change in the Sub-antarctic
Macquarie Island has experienced a marked shift in its climate since 1970, with increasing precipitation, accompanied by a steady increase in mean wind speed associated with increased cyclonic activity. These trends are consistent with an increase in the Southern Annular Mode (SAM) index, albeit with a shift to an anomalous atmospheric trough over the western Pacific Ocean. However, our underst...
