Three sediment pushcores were collected manually from the White Oak River, Station H. Cores were transported to the Institute of Marine Sciences in Morehead City, NC, and sectioned at 3 cm intervals.
Capable of being performed in numerous environments, push coring is just as it sounds. Push coring is simply pushing the core barrel (often an aluminum or polycarbonate tube) into the sediment by hand. A push core is useful in that it causes very little disturbance to the more delicate upper layers of a sub-aqueous sediment.
