Abstract

Equipment for use by SCUBA divers to collect cores of firmly packed nearshore sands up to six feet long is described. The tools consist of plastic sampling tubes, steel hammering cap and hammering sleeve, aluminum extracting handle, and metal and rubber sealing plug. These tools are simple, rugged, inexpensive to build, and can be operated entirely by touch in waters of zero visibility. They were used in August 1962 off the Virginia coast, and in August 1967, off Long Island to collect cores of nearshore quartzose sands of varying grain size, and in March 1965, off the north coast of Jamaica, to collect cores of carbonate sands and muds.
