This paper describes a number of instruments used to take samples or make measurements necessary for the study of pollution in inshore coastal waters. Extreme care in sampling is required when measurements of trace elements must be made in the range of a few parts per billion, and of pesticides at a few parts per trillion. The amount of uptake of pollutants into marine animals of aerial fallout of lead and DDT on the water surface, and of the motion of water masses can be measured only if the scientist is properly equipped. Some of this equipment is rapidly changing; the television we were satisfied with only 2 yr ago has been outclassed by the 1976 models. Even very simple-appearing pieces of equipment such as grab samplers can produce very different results. The accent must be on thoughtfulness and on careful work at sea.
