Dongfanghong 2, a marine expedition boat, has become a technical role model for dynamic marine environment watch. It gathers numerous advanced technologies and equipment, including an integration system, an instrument based comparing and analyzing system, a special lab and associated supporting equipment, an integrated system monitoring platform, a special local network for data transmission, integration and demonstration software, ADCP, a CTD system for a depth of 6000m, a CTDC with an accuracy of 6000m, a self-contained CTD at a depth of 1000m, a PAADCP, an ACCP, and a dragging multi-parameter section measuring system.
The new integration and demonstration system has stood an 80-day on-the-scene test over China?痵 South Sea and northwest waters of the Pacific Ocean, with a combined cruising mileage over 10,600 sea miles. Researchers conducted a full-fledged performance test on the on-board equipment and instruments, and made consecutive comparisons with their international counterparts. The test travels through 148 stations, and 3 2000-m consecutive stations, with 5 rounds of dragging test for CTD at a depth of 5000m, and 3 rounds of diving buoy releasing and retrieval at a depth of 2000m.
