A double-tube coring device able to retain sampled core, to recover sandy sediments, and to be easily extracted, has been designed. It consists of two PVC pipes with an intervening air space. The inner tube takes the main stress of coring, the outer tube acts as a sleeve to provide an environment of minimum friction for withdrawal. The corer is fitted with an anvil, and driven into the sediment by hammer blows. Sensitive variation of hammering force when cutting the core enables excellent recovery, with little or no compaction, of a range of sediment types.
