Bibliography

Gives guidance on the sampling of unconsolidated sediments for the determination of their geological, physical and chemical properties, as well as the determination of biological, microbiological and chemical properties at the water and sediment interface.

This document provides guidance on the sampling of unconsolidated sediments for the determination of their geological, physical and chemical properties, as well as the determination of biological, microbiological and chemical properties at the water and sediment interface. Guidance on achieving sediment cores is given specifically for the measurement of rates of deposition and detailed strata delineation. The main emphasis of this document is to provide methods that achieve sediment samples.

The environments considered are

• limnic (rivers, streams and lakes, natural and man-made), and

• estuarine, including harbours.

Industrial and sewage works for sludges, paleolimnological sampling and sampling of open ocean sediments are specifically excluded from this document (and are addressed in ISO5667‑15 ), although some techniques may apply to these situations. Sampling of suspended solids is outside the scope of this document and reference can be made to ISO5667‑17 for such guidance.
