Abstract:

A long, wide-diameter corer with a waterproof core-catcher is described. Its design is closer to theoretically ideal proportions than most oceanographic corers, and the cores it provides appear to be unmodified samples of the sediments. A sphincter-type, nylon-sleeve core-catcher seals the cores within a waterproof container during retrieval. An electrical triggering system for this and other heavy corers, is described. The use of a mercury switch instead of counterweights prevents accidental triggering by sudden shocks, thereby making it much safer than other systems when working in heavy seas. Author
