Instrument: Gravity Corer
The gravity corer allows researchers to sample sediment layers at the bottom of lakes or oceans. The coring device is deployed from the ship and gravity carries it to the seafloor. (http://www.whoi.edu/instruments/viewInstrument.do?id=1079).
Eastern Mediterranean sediments were collected by gravity corer. In the Marmara Sea, deeper sediments (from 570-585 cm and 520-530 cm) were collected by gravity corer.
