For example, in 1969 scientists from the Universities of Bergen (Norway) and Minnesota, Connecticut and California, Los Angeles (USA), and the US Coast Guard Oceanographic Unit studied the formation of Antarctic Bottom Water, the population density and diversity of the deep sea benthos of the Weddell Sea, the population dynamics of Antarctic seals and sedimentation processes in the Weddell Sea and carried out physical, chemical and photographic oceanographic surveys.[4]. The distributions of temperature and salinity indicate a cyclonic circulation of the subsurface water masses. 28 talking about this.

The outflow of Weddell Sea Bottom Water and Antarctic Bottom Water formed in the Weddell and Ross Seas is a major source of oceanic deep water and changes affecting the formation of these water masses are liable to have an effect on the circulation of deep water globally.

Other subjects of IWSOE research include the Weddell Sea currents and the biology of krill, a species of zooplankton abundant in the area. At the time, the … The altered coastal current water then mixes with warm deep water (>0.2°C, >34.67‰) along the continental slope in approximately 1∶2 to form antarctic bottom water (−0.4°C, 34.66‰). USCGC Glacier WAGB-4. Processes, Information The dashed lines postulate mixing between shelf (K) and slope (D) waters to yield the observed bottom water (B). Antarctic bottom water then flows out of the Weddell Sea between 50° and 15°W longitudes and 60° and 65°S latitudes.

With a relatively short length in proportion to the great power developed, her bow had the characteristic sloping forefoot that enabled her to ride up on heavy ice and break it with the weight of the vessel. Weddell Sea cores were collected during the 1968-70 International Weddell Sea Oceanographic Expedition (USCGC Glacier), and on ARA Islas Orcadas cruises 1578 (I428, I4 29). Oceanography, Interplanetary Glacier's shakedown cruise and maiden voyage were combined in "Operation Deep Freeze I", as flagship for Rear Admiral Richard E. Byrd.

No official caption; Photo No. [1] The water of the Weddell Sea is about 1400 m deep at its deepest point; it is exceptionally clear (the Secchi disk visibility reading at 80 metres recorded in the Weddell Sea on 13 October 1986 was the deepest ever, at the theoretical maximum in absolutely pure water). IWSOE research projects have involved a variety of institutions and covered a wide range of disciplines. The curved dashed line is an isopycnal USCGC GLACIER WAGB-4.

Glacier was first icebreaker to make her way through the frozen Bellingshausen Sea, and most of the topography in the area is named for her crewmembers.

USCGC Glacier, 25 February 1970. Northwind was one of the icebreakers designed by Lieutenant commander Edward Thiele and Gibbs & Cox of New York, who modeled them after plans for European icebreakers he obtained before the start of World War II. USS Glacier (AGB-4) (later USCGC Glacier (WAG/WAGB-4)) was a U.S. Navy, then U.S. Coast Guard icebreaker which served in the first through fifteenth Operation Deep Freeze expeditions. 203.380.3538 Cell. Bottom water formation in the western Weddell Sea 369 During IWSOE 75 the Glacier attempted to penetrate the western Weddell Sea from the east along about 68 (FosTER, 1975). $2.50. Figure 1. James M. Seabrooke, United States Coast Guard Oceanographic Report No. and 1959-60. Geophysics, Mathematical The Glacier was essentially an improved Wind class icebreaker, larger and more powerful.

Both Please check your email for instructions on resetting your password. The stern was similarly shaped to facilitate breaking ice while backing down. W. Both Our emergency cache on the north side of the Erebus Glacier Tongue. The positions and spatial orientations of the ice edge were different in the two periods. Her first encounter with the ice was in December 1955, breaking through the Ross Ice Pack, she carved out an ice harbor in Kainan Bay to allow the discharge of cargo from vessels at the site for Little America V. Glacier continued 400 nautical miles (740 km; 460 mi) west to break ice into an off-loading site to establish the U.S. We hypothesize that this water mass is formed by alteration of coastal current water as it flows along and beneath the vast ice shelves in the southern Weddell Sea. In 1970, this Coast Guard vessel ended up trapped deep in the Weddell Sea.
