Recently, the satellite-based Vessel Monitoring Systems (VMS) have been widely deployed on fishing vessels. Recognition of fishing activity is the key task for various applications. Previous approaches are basically according to change of vessel's speed; or rely on the validated data from logbooks or documented observations. In this paper, with a rated 60-second temporal resolution VMS data for two...
Data collection and transmission are crucial tasks in current marine surveillance systems. Each node samples in a specific area and transmits its sensing data back to the land by satellites. In this paper, we propose a methodology of a vessel-based ocean monitoring delay tolerant networking (VOM-DTN) which is a cost saving DTN utilizing the existing vessels' daily working voyages to transmit ocean...
OceanSense is an offshore sensor network to achieve continuous surveillance on the sea environment, which has been deployed for one and half years. In order to present the monitoring data of OceanSense, we adopt the Google Services based web architecture. This paper illustrates the whole design of the sensor web of OceanSense (OsnWeb), including ocean environmental data's collection, sharing and visualization...
The specialities in ocean environmental information data prevent themselves from being exploited efficiently in ocean science research. The combination of the data grid technology with ocean science provides the promising future for sharing and exchanging of ocean environmental information data. This paper illustrates the construction of OceanGrid, which is the data grid of ocean environmental information...
