Ever wished you had Superman’s X-ray vision? Our new digital seismic streamer is the next best thing.
The ‘GeoEel’ streamer is an array of 768 hydrophones towed behind a ship. The hydrophones pick up sound signals reflected off sedimentary layers and geological structures up to 3 km beneath the seabed. These signals are processed to produce detailed images, like this profile of sedimentary basins in the Gulf of California.
These profiles have many applications, including:
examining natural underwater hazards;
coastal engineering and mineral resource assessment;
studies of sea-level rise and seafloor erosional processes.
The new system records sound digitally, resulting in a stronger signal than our old analogue system. It can be scaled up to a longer streamer equipped with more than 4000 hydrophones for even greater detail.
