Core Cookie Cutting

January 11, 2007

Stainless steel “core catchers” are fresh off the production line. These hand-made fabrications are inserted in the bottom of various sediment coring devices. They open up when the core pipe penetrates the sea floor, allowing sediment to enter, and then spring closed at the moment of extraction to prevent any sample loss during recovery.
