Detailed Description
Multichannel seismic streamer (green) on the fantail deck of R/V Solstice. The streamer contains dozens of hydrophones (underwater microphones) that record sound transmitted by an acoustic source bounced off features beneath the seafloor. The tan cable is part of the sound source called a minisparker.
