Abstract: We present a bottom water sampler made of a plastic bottle, a
weight, and four pieces of rope which can be operated by one person from any
working platform in shallow-water environments. The measurements of our sampler
were equal to those taken with a Niskin bottle. The water sampler was
operational in tidal currents up to 0.6 ms-1 and may be used in water at least
10 m deep.
