Cruise Report






The main exploration mission of R/V Legend includes: performing the exploration mission of deep sea working-type underwater unmanned vehicle, sampling operations of marine sediments and giant long cores, oor topographic mapping of high-precision and full-depth sea and collection of sub-bottom data etc. In addition to the above-stated missions, it can simultaneously perform the general technology and research mission of hydrological data collection and water sampling operations, deployment/recycling of sea weather buoys and sediment trap array, and education/training of ocean science & technology equipment. It is our belief that R/V Legend will add the new energy to the Taiwan ocean science research, and the territory of in-country ocean science & technology will be expanded to establish the new milestone of Taiwan ocean science & technology.
