Sercel recently sold one of its new Sentinel HR high-resolution solid streamers to the Alfred Wegener Institute (AWI), the German research foundation specialising in polar and marine research in the Arctic and Antarctic.

AWI will use the streamer to record critical data on the relationship between geological activity and ecosystems to gain a better understanding of the Earth's system.

Launched last year, Sentinel HR is the latest addition to the French company's solid streamer suite. With a close channel separation of 3.125m, it is designed for shallow target applications and high-resolution 3D surveys. It also delivers outstanding hydrophone performance. Driven by Sercel's new generation Seal 428 marine seismic recorder, up to 6km of Sentinel HR can be deployed with full data and power redundancy for non-stop acquisition.

To optimise marine mammal detection during seismic acquisition, AWI has also added the combination of Sercel's SeaPro Nav integrated high-end navigation system and QuietSea Passive Acoustic Monitoring (PAM) system to its marine seismic portfolio. SeaPro Nav provides accurate real-time positioning for all marine seismic surveys while QuietSea complies with international marine mammal monitoring regulations.
