Abstract
An instrument is described, which collects water from the benthic boundary layer in shallow waters with a maximum depth of 50 m. Four water samples of 71 each can be collected between 5 cm and 40 cm above the sediment. Handling is easy, and the sampling operation is short enough to allow repeated employment even on time-limited, routine investigations. First results show gradients in the organic matter and seston content of samples from the 5 to 35 cm above the sediment. The oxygen concentrations near the sea bottom decreased faster than those 3 m above, just below the summer pycnocline.
