The instrument is ideally suited to site residency and migratory studies of marine fauna over an extended period, and is suitable in offshore deployments. The VR4-UWM records the ID and time stamp from coded transmitter tags deployed on marine fauna that enter the receiver's range. Temperature, depth and acceleration data can also be collected. The instrument subsequently transmits this data to a surface unit, which can be loaded to a PC in the field without the need to retrieve the instrument. The VR4-UWM has a maximum depth rating of 500 m. It can store more than 800000 detections and be deployed undisturbed for more than six years."@en ; skos:inScheme ; skos:notation "SDN:L22::TOOL1161" ; skos:note "accepted"@en ; skos:prefLabel "Vemco VR4-UWM Underwater Modem Receiver"@en ; skos:related .
