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.
