Simulations of the ocean dynamics in the cavity under the Amery Ice Shelf, Antarctica, were carried out using a three-dimensional numerical ocean model. Two different boundary conditions were used to describe the open ocean barotropic exchange at the ice front.
The snow cover on sea ice is an integral component of the sea ice environment. It … accumulates throughout the year and has a significant impact on the surface energy … balance due to its high albedo and insulative properties.
The basis of using isotopic measurements to study trophic structure lies in documenting a regular and consistent pattern of isotopic enrichment with increasing trophic level. Nitrogen isotope ratios (δ 15N) in consumers become enriched in 15N by 3-4 % relative to their food…
The Dome Summit South ice core from Law Dome, East Antarctica is 1200 m long and reveals an unusually high accumulation rate for Late Holocene precipitation (640 kg m2/a), dating to 90,000 years before present (BP) at its base.
1. The likelihood that seabirds will be hooked and drowned in longline fisheries increases when baited hooks sink slowly. Fishermen target different fishing depths by setting the mainline through a line shooter, which controls the tension (or slackness) in the line.
The total ozone column (TOC) in the 'collar' region outside the Antarctic Ozone Hole exhibits a pronounced wave-1 zonal pattern in austral spring. During the period 1979-2005, the zonal minimum of the pattern exhibited a general eastward shift of approximately 45 degrees of longitude…
