jet corer
Consists of a length of pipe that is lowered from a vessel to obtain samples. Highvelocity water is pumped through the pipe, and the jetting action of this water issuing from the lower end of the pipe very effectively cuts a hole in the unconsolidated overburden sediments. Once at bedrock, the pipe is rammed into the rock with sufficient force to obtain a plug several inches in length.
