In ecological studies of benthonic organisms it is advisable to sample the water immediately above the sediment-water interface rather than centimetres or metres above the bottom. The standard oceanographic water samplers cannot be relied upon to sample at the required level so a new instrument was designed. The instrument here described is a strengthened and simplified version of that described for use in shallow waters (up to 4 m) by Murray (1963). It has been successfully used in waters of up to 60 m deep but should withstand depths of up to 180 m.
