Antarctic Polar Frontal Zone from Australia to the Drake Passage
Antarctic Polar Frontal Zone Australia Drake Passage
2009/3/7
North-south temperature sections drawn from historical XBT observations averaged over various longitude bands are compared with sections drawn from existing hydrographic data. Corresponding features i...
Structure and Transport of the Antarctic Circumpolar Current at Drake Passage from Short-Term Measurements
Antarctic Circumpolar Current Short-Term Measurements Drake Passage
2009/3/7
Three-week average speeds from an array of current meter moorings which spanned Drake Passage were used in conjunction with geostrophic calculations to estimate the short-term transport of the Antarct...
Antarctic Polar Front Zone in the Western Scotia Sea—Summer 1975
Antarctic Polar Front Zone Western Scotia Sea Summer 1975
2009/3/7
The component of the FDRAKE-75 data obtained by the R/V Conrad in the western Scotia Sea reveals a definite sequence of thermohaline stratification zones encountered on passing from Antarctic to Sub-a...
Model calculations of the age of firn air across the Antarctic continent
Model calculations firn air Antarctic continent
2009/3/4
The age of firn air in Antarctica at pore close-off depth is only known for a few specific sites where firn air has been sampled for analyses. We present a model that calculates the age of firn air at...
A Cyclonic Eddy in the Antarctic Circumpolar Current South of Australia：Results of Soviet-American Observations Aboard the R/V Professor Zubov
Cyclonic Eddy R/V Professor Zubov Antarctic Circumpolar Current
2009/2/23
Hydrographic, expendable bathythermograph and 16-day current meter records are combined to describe the oceanic structure south of Australia (along 132°E) between 24 January and 1 March 1977. A strong...
In February 1977 a column of water (14 km radius), within the central region of the Weddell Gyre west of Maud Rise. was observed in which the normal Antarctic stratification sequence of temperature-mi...
An assimilated data base of total column ozone measurements from satellites has been used to generate a set of indicators describing attributes of the Antarctic ozone hole for the period 1979 to 2003,...
Differences in Arctic and Antarctic PSC occurrence as observed by lidar in Ny-Ålesund（79° N, 12° E）and McMurdo（78° S, 167° E）
Arctic Antarctic PSC lidar Ny-Å lesund McMurdo
2009/2/16
The extent of springtime Arctic ozone loss does not reach Antarctic ``ozone hole'' dimensions because of the generally higher temperatures in the northern hemisphere vortex and consequent less polar s...
Modal Properties of Antarctic Intermediate Water in the Southeast Pacific and the South Atlantic
Antarctic Intermediate Water Subantarctic Mode Water
2009/2/13
Modal properties of Antarctic Intermediate Water (AAIW) are determined from bivariate distribution diagrams for two regions in the southeast Pacific and two regions in the South Atlantic. The volumetr...
On the Estimation of Absolute Geostrophic Volume Transport Applied to the Antarctic Circumpolar Current
Absolute Geostrophic Volume Transport Antarctic Circumpolar Current
2009/2/13
An objective method of estimating the geostrophic barotropic volume transport across an oceanographic section is developed and applied to the transport of the Antarctic Circumpolar Current through the...
Melting of Ice in Sea Water：A Primitive Model with Application to the Antarctic Ice Shelf and Icebergs
