The Hunga Tonga-Hunga/Hunga-Ha'apai eruption on January 15, 2022 sent off a plume of ash material up to the stratosphere and triggered a meteotsunami and … barometric pressure pulse that rippled through the atmosphere and oceans all around the world.
We present here data of mineral dust variability retrieved from an ice core of the central West Antarctic, spanning the last five decades. Main evidence provided by the geochemical analysis is that northerly air mass incursions to the coring site, tracked by insoluble dust microparticles…
While definitive winter measurements for Dome C must await until 2004, on the basis of existing data the Antarctic … Dome sites promise the best conditions on the Earth for many astronomical observations. Because atmospheric … turbulence is largely confined to a ~ 100 m ground layer…
The Antarctic ice cap is a unique vantage point from which to … observe the global background of black carbon aerosol (BC). Far … removed from sources, BC in the Antarctic atmosphere is largely … due to biomass burning at low- to mid-latitudes modulated by … upper tropospheric…
We present a proposal for an 8.4 metre off-axis optical/IR telescope to be located at Dome C, Antarctica. LAPCAT will use a mirror identical to the offset segment recently cast for the Giant Magellan Telescope (GMT) as a completely unobscured f/2.1 primary.
An ice core, drilled near the margin of the Law Dome ice cap at Cape Folger, has been analysed for trace chemical content.
Black-browed and grey-headed albatrosses breed at four known locations in Chile: Islas Diego de Almagro, Islote Evangelistas, Islas Ildefonso and Islas Diego Ramirez.
Black-browed albatrosses breed at four known locations in Chile: Diego de Almagro (15,900 pairs, Lawton et al. 2003), Evangelistas (4,700; Arata et al. 2003), Ildefonso (47,000; this presentation) and Diego Ramirez (55,300; Robertson et al. unpublished). After the Falkland Islands/Islas Malvinas…
