Abstract

It is necessary to detect any spilled-oil condition on/in the sea for cleaning and to analyze seawater containing oil for monitoring any micro pollutant in the marine environment. For possible countermeasures, we have developed oil sensors with various configurations for wide scale and real-time monitoring. The first system involves two-dimensional detection applied for a remote sensing (LIDAR) technique and fluorescence analysis. The LIDAR system was used to carry out scanning on the sea surface near Oki Islands onboard an airplane. We succeeded to obtain energy-selected images from the airplane. Furthermore, we tried to analyze micro-contained oil in seawater for a continuous environment analysis onboard a ship. This system can detect oil in seawater at about 50 ppb. We are considering a microanalysis system adapted for monitoring onboard a ship as an observing platform. Our systems are useful for monitoring from macro pollution to micro-contaminated detection in/on the marine environment.
