Tripod modification of sphincter corer : construction, operation, core extrusion and sampling efficiency
MetadataShow full item record
A 21-cm diameter sphincter corer (Burke, 1968) has been modified by mounting it in a tripod frame. This modification results in more dependable recovery of undisturbed surficial sediment and greater penetration into firm sediment. The device is useful in water depths from 2-6000 m, is adaptable for use on small boats, is very easily employed on large research vessels, and can be readily disassembled for more convenient transporting and storing.
