A low-cost gravity-style corer capable of multiple sediment recovery drives

Abstract Gravity sediment corers have long been useful in recovering lake sediments for paleoenvironmental analysis, particularly in deep lakes or other situations that preclude the use of other coring systems. However, they have been limited to a single sediment recovery drive. The gravity coring system described in this paper is capable of single or multiple sediment drives and can be constructed out of commonly available materials.
