摘要：

A modified kasten core barrel was developed to obtain cores with nearly 100% sediment retrieval while minimizing disturbance of the sediment/water interface. One side of the 15 × 15 cm square barrel is doubled by a second movable plate which can be moved upwards by a series of hand screws thus enabling complete sideways extrusion of the core. This produces a set of subcores or slabs of equal quality with preserved stratigraphy which can be X-rayed, subsampled, stored or frozen for geochemical studies. The new kasten core barrel is effective in rough weather, inexpensive to build, easy to handle and enables fast core processing on board. © 1990.
