Abstract The main types of deep-sea sediment coring devices are described and their relative merits and drawbacks are discussed. These devices include box corers, gravity corers, piston corers, giant piston corers and vibrocorers. Recent utilisations of kevlar and polyester coring warps are also discussed, since these are the only warps capable of handling the large weights associated with the larger devices. Recent developments in wholecore logging, including ‘P’ wave, density and magnetic susceptibility, are described as are methods of subcoring and core splitting to obtain the maximum amount of detail on the split surfaces. The wholecore logs together with a good colour photograph of the recently split sediment surface provide a lasting unambiguous record of the core.
