WebThe Abrams gravity corer (fig. 16.41) is a self-contained coring system designed to improve the standard gravity coring techniques and increase production rates. In other respects, the application of the Abrams device is the same as for standard gravity corers. It is particularly suited to deepwater sampling where a controlled free-fall is optimal. WebA core sample is a cylindrical section of (usually) a naturally-occurring substance. Most core samples are obtained by drilling with special drills into the substance, such as sediment or rock, with a hollow steel tube, called a core drill. The hole made for the core sample is called the "core hole". A variety of core samplers exist to sample ...
