| With the development of the indigenous XBT, the use is boosting in ocean observation. Therefore, Xiamen University carried out “In situ comparison-testing and standard inspection procedure for applicability of oceanographic monitoring equipment (the National 863 Program) ” in the northeast south China sea. It aimed at inspection and verification of the indigenous XBT which had mature technology for commercial production. In the sea trials, we firstly evaluated the precision of the imported XBT by comparing the profiles with CTD in different fixed-positions, and then compared the indigenous XBT with the imported at the underway observation. The result indicated that the indigenous XBT showed good performance and the success rate was approximate 80%. The precision of some indigenous was close to the imported, but the invalid temperature profile was more. Meanwhile, we found that the precision of the imported XBT was too low to satisfy the requirement in the test, so we couldn’t get the actual precision for indigenous XBT, but the result still had importance reference value. This test will provide supports for the massive applications and promotion of the indigenous XBT and can be used for reference for other XBT/XCTD/CTD and so on. |
