THE 'MONO' CORER: A WIDE DIAMETER, GENERAL PURPOSE, GRAVITY CORING TOOL.
NAVAL POSTGRADUATE SCHOOL MONTEREY CALIF
Pagination or Media Count:
A gravity corer in its simplest form consists of a tube with a check-valve at the upper end which is driven into the sediment by encircling weights in order to obtain a sample. At many oceanographic institutions where a variety of research is undertaken relative to the ocean bottom, an efficient and reliable general purpose coring device is required. Such a device should enable the biologist, geologist, sedimentologist, or engineer to obtain a sample which meets his particular requirements. A simple gravity corer fits many of these needs. The gravity corers in use at the present time have not significantly changed from the earlier corers. Even the most reliable of gravity corers are not without some drawbacks. An attempt is made herein to solve some of these problems and produce a reliable, easy to handle, general purpose, gravity coring tool useful for all phases of oceanographic research. Author
