Our project activities focus on the analysis of digital data obtained by satellite and airborne sensors, and on the development of applications of these data at local, regional, and global scales. The main objective is to provide a better understanding of the world oceans on a large spatial and temporal scale. In situ optical and biological data are collected for ground truthing and to relate the apparent and inherent optical properties of water constituents with the remote sensors' signal. We specialize in coastal processes of highly variable regions like the Gulf of Thailand, the Andaman Sea and Southeast Asia using instruments such as AVHRR, CZCS, SeaWiFS, MODIS, and Landsat. We use other sensors such as altimeters and scatterometers to examine the physical environment in the adjacent deep ocean.
