520 | |a"The requirement for an inexpensive reliable means of collecting time-integrated, near surface water samples at numerous stations around a point-source effluent, led to the development of an unpowered, moored sampler which could be deployed, serviced, and recovered by hand from a small boat. The sampler consists of a container held at a fixed depth on a ballasted spar. The interior of the container is vented to the atmosphere, and open to the ambient water mass via a nozzle assembly protected by a fine mesh filter. The pressure differential across the nozzle is sufficient to maintain a very small but constant flow into the container, such that sampling periods greater than twelve hours are achieved. By observing the assembly and operational precautions outlined in the text, the configuration described will operate reliably for at least several weeks"--Abstract, p. v. |
