Abstract
An underwater sampler has a tubular body having closures biased to move from open to closed positions. The closures releasably may be latched in their open position by a latch mechanism having retainers separably coupled to anchor cables attached to the respective closures. The latch mechanism may be actuated by a weighted messenger or by a sharp tug on a hoist line by which the tubular body is suspended at a predetermined level in a body of water from which a sample is to be taken.
