Monitoring of Anthropogenic Influence on Water Areas of Hawaiian Islands Using RADARSAT and ENVISAT Radar Imagery

摘要

This paper discusses results from satellite monitoring of anthropogenic influence on coastal water areas caused by a deep outfall in Mamala Bay (Oahu Island, Hawaii) using RADARSAT and ENVISAT data. The propagation area of anomaly surface manifestations caused by this anthropogenic impact was detected by considering informative features of radar images using method of the statistically significant sliding window. Sea truth data on hydrophysical field and wind field characteristics for the studied area in 2003 - 2004 was also used during monitoring. Recommendations on how to decrease the anthropogenic pressure on the Mamala Bay water area (Oahu Island, Hawaii) are developed based on the satellite monitoring results.
