Abstract : The patent refers to a pressure differential seafloor corer-carrier for obtaining long core samples of seafloor sediments. The corer-carrier is composed of two main components: The first component is a pump assembly that pumps seawater and sediment as to create a negative pressure differential; the negative pressure differential being the driving force that forces the corers into the seafloor such that cores of over 100 feet in length can be obtained. The second component is a space frame mounted and fastened to the pump and functions as a rack to which conventional corers are attached. Once the corers are embedded to their full length, the pump is used to create a positive pressure differential which helps remove the corer-carrier from the seafloor.
