Georgia Tech's Edgetech 512 system

The yellow instrument is Georgia Tech’s Edgetech 512 system, which is known to scientists as a “fish.” The instrument is towed on a cable at tens of meters below the sea surface. The instrument sends out a relatively high frequency acoustic pulse that is then reflected off the sea floor and shallow features within the sedimentary column.
