| Abstract;This study describes the detection of ballast water exchangeable seas using MODIS/Aqua-derived diffuse attenuation coefficient (K(490)) synchronized with in situ ballast water sampling and analysis along the LNG carrier's routes between Japan and Qatar during the period from 2002 to 2005. Study areas include the northwestern Pacific Ocean, the East China Sea, the South China Sea, the Bay of Bengal and the Arabian Sea. Based on the relationship between K(490) and corresponding in situ plankton cell densities, ballast water exchangeable seas are detected to meet the regulation of ballast water performance standard of International Maritime Organization (IMO). Furthermore ballast water exchangeable seas are extracted from MODIS-derived K(490) images overlaid with the depth and the distance from shore to meet the IMO regulation of ballast water exchange area. As a result of the application of K(490) with these IMO's regulations for five regional seas, the Bay of Bengal is detected as a suitable ballast water exchangeable sea except an anomalously high K(490) area found off the coast of Sri Lanka during the northeast monsoon in 2005. Seasonal and annual variations of K(490) along the LNG carrier's routes will be discussed in order to establish an early routing system for suitable ballast water exchangeable seas. (author abst.) |
