In his second blog on measuring the restless earth, Geraint West, Global Business Manager for Ocean Science, explained how Sonardyne technology is being used to measure underwater landslides down the sides of Mount Etna. In this, his third blog, in a three-part series, he explains how an emerging technique called GPS-Acoustic (GPS-A) is having a …

To do real-time SLAM, a new set of algorithms was developed using raw ranges from Compatt 6+ transponders in the SPRINT INS, which is in turn managed by Fusion 2, all in real-time. All you need is a ROVNav 6+ on your ROV, a SPRINT-Nav (or SPRINT INS and a DVL), and one Compatt 6+ …

In his first blog on monitoring the restless earth, Geraint West, Global Business Manager for Ocean Science, explained how scientists are able to measure underwater ‘avalanches’, or oceanic turbidity currents using our Autonomous Monitoring Transponders (AMTs). In this second blog, of a three-part series, he explains how the same versatile instruments are being used to …

On land, rapid events like landslides and earthquakes are easily measured with satellite imagery, while precise measurement of much slower tectonic plate movements using space geodesy techniques have become routine. Unfortunately, neither of these techniques work underwater, which has meant that such measurements have stopped at the waterline – until now. In a three-part blog, …
