Abstract
A new automated plankton sampler is described that collects, compartmentalizes and preserves up to twelve individual samples, from any depth up to 400 meters, in fast or slow flowing waters.
The unit combines the already well established features characteristic of other modern samplers but offers many distinct advantages. The O'Hara sampler features a novel fully automated self generating flow through system that is electronically preset by the operator, and upon submergence need not be retrieved for a period up to several days.
The unit is simple in its design and challenging in its applications for use in pure and applied scientific research.
