This part of ISO 5667 provides guidance on the sampling of sedimentary materials from — inland rivers and streams; — lakes and similar standing bodies; and — estuarine and harbour areas. Industrial and sewage works sludges, palaeolimnology sampling and open ocean sediments are specifically excluded although some techniques may apply to these situations. Sampling specifically for the measurement of rates of deposition, other transport criteria and detailed strata delineation is not within the scope of this part of ISO 5667. The investigation may have the following objectives: — the descriptive mapping of an area; — the monitoring at regular intervals of fixed markers such as buoys; — examining the quality of dredger spoil; and — fundamental research.
