| 摘要： | This report describes a test to evaluate performance of a towed CTD chain manufactured by ADM Elektronik (Germany) and owned jointly by ARL/Penn State and APL/University of Washington. The test was conducted in the vicinity of 71.2 E, 40.2 N on the continental shelf of the US, in preparation for the SW06 experiment, which calls for the chain to be towed repeatedly through nonlinear internal wave (NLIW) packets. As configured for this test, the towed CTD chain employed 48 conductivity, temperature and depth (CTD) fins spaced 3m apart on a 150m long cable terminated at the bottom by a V-fin depressor. The test successfully determined 2 kts to 10 kts towing speeds and ship turning rates that are viable operationally and scientifically. A problem was encountered with towing a shortened scope at speeds greater than 4 kts. In general, the checkout test produced results that demonstrate the wealth of information available from the towed CTD chain. / NOTE:Final rept., 1 Sep-31 Dec 2005. |
