AN ELECTRO-OSMOTIC KNIFE FOR SLICING LARGE BOX CORES

Large box cores can be sliced vertically or horizontally on board ship with a knife that has an electrified metal blade. The knife operates on the principle of electro-osmosis, which reduces drag along the blade during slicing and minimizes distortion of the sediment. The slices are useful for subsampling the core and for studying physical and biogenic sedimentary structures. Making slices helps solve the problems of handling, storing, and shipping the large volumes of sediment recovered in box cores. /Author/
