Scope: What is BS EN 17218 - Mesozooplankton sampling about? BS EN 17218 discusses mesozooplankton sampling from marine and brackish water. BS EN 17218 specifies procedures for the sampling of mesozooplankton using nets and continuous ribbon-sampling devices in marine and brackish waters for the purpose of water quality assessment and determination of the ecological status of ecosystems. Guidance on sampling procedures and the subsequent steps of preservation and storage are given. The sampling procedures allow estimates of species occurrence and their abundance (relative or absolute), including spatial distribution and seasonal and long-term temporal trends, for a given body of water. The described methods are restricted to the sampling of mesozooplankton that inhabit marine and brackish waters and exclude the shallow littoral zones which require a different type of sampling (e.g., zooplankton in salt marshes). Who is BS EN 17218 - Mesozooplankton sampling for? BS EN 17218 on mesozooplankton sampling is used by: Government laboratories
