... ABSTRACT Visual detection of whales during seismic surveys for mitigation purposes is a labor intensive and exhaustive task, feasible only during daylight hours. These constraints are overcome by the MAPS (Marine Mammal Perimeter Surveillance) system, which employs a ship-borne, 360°, cooled...

... Summary The seismic streamer is a thin tube under tension that is neutrally buoyant, so it behaves like a thin string of sea water. Vertical streamer string waves can be generated by motion of the ship, cable depth controllers, or sea surface waves. A one centimeter change in streamer depth...

... of the signal. To meet these dcsignconstraints the streamers/sources must be towed some considerable distance from the ship and therefore they cannot bc assumed to have a position which is just a simple offset from the position of the ship. Indeed for many years now, it has not been acceptible to assume...
