Data rolling in....
Example of data recorded on seismic streamer after one pulse from the seismic sound source. This image shows a sound waves that have bounced off of the seafloor and underlying l ayers. After processing, it can be used to create a picture of geology under the seafloor. Ever since we finished rolling out the 15-km (~10 mile) seismic streamer and seismic sound source, the seismic data have been rolling in. Each time we emit a pulse of sound waves from our seismic source, we acquire recordings of seismic energy that have traveled into the earth, bounced off of rock layers below the seafloor, and returned to the sea surface. The Langseth ’s seismic streamer has 1200 channels that record returning sound waves at a sample rate of only 2 milliseconds for 26 seconds – enough time for seismic energy that has traveled deep into the earth to return to the sea surface an...
