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
- Geological scientists
- Marine ecosystem scientists
- Climate change scientists
- Environmental risk management teams
Why should you use BS EN 17218 - Mesozooplankton sampling?
The Zooplankton community is an important part of the pelagic food web, since it forms the link between primary producers and higher trophic levels. Changes in phytoplankton biomass and species/size composition change mesozooplankton community structure and productivity. Such changes potentially influence fish stock recruitment and sedimentation (i.e. indirectly affecting oxygen concentration in the bottom water).
BS EN 17218 provides a procedure to identify and enumerate zooplankton collected in nets which is utilized to estimate quantitative information on diversity, abundance, and biomass with regard to spatial distribution and long-term temporal trends for a given body of water. BS EN 17218 helps you to monitor changes in marine ecosystems.
