Abstract

Abstract:

Based on observations of geo-stationary meteorological satellite data, lots of brightness temperature anomalies on the satellite-based thermal infrared remotely sensed images are found along the offshore China seas. After analyzing the brightness temperature anomalous features, and relating these anomalies to the conventional oil & gas fields and non-conventional potential gas hydrate occurrences, the mechanism of the anomaly is discussed. According to these anomalous implications, some possible areas for gas hydrates are pointed out,such as the Xisha Trough, the Dongsha island slope, the marginal Bijianan basin, the North Luzon Trench, the Nansha Trough, the Middle-south to Southwest Okinawa Trough etc.

Key words: brightness temperature anomaly, satellite-based thermal infrared remote sensing, gas hydrate, the offshore China seas
