Project Number | 51 |
Date of Summary | December 31, 1986 |
Subject | Engineering Properties of Subsea Permafrost |
Performing Activity | U.S. Army Corps of Engineers, Cold Regions Research and Engineering Laboratory |
Principal Investigator | Mr. Edwin J. Chamberlain |
Contracting Agency | Minerals Management Service |
Estimated Completion | Complete |
Description | The objective was to assess the
engineering properties of subsea permafrost and their influence on bottom- founded
structures. Four basic areas of study are proposed:
|
Progress | Complete. All of the proposed laboratory work is complete with the exception of analysis of the engineering properties of cores from the Beaufort Sea. These cores were to be obtained by the U.S. Geological Survey, Marine Geology Branch from a drill ship in 40 to 50 meters of water during the open water season of the summer of 1983. However, ice conditions in the Beaufort Sea prevented the drill ship from accessing the drill sites, therefore the cores are not available. When it was found that cores would not be available, it was requested that the work study the seasonal freezing processes in the Beaufort Sea. |
