ECN Protocols

The measurements made by ECN cover a wide range of physical, chemical and biological 'driving and response' variables identified as being important for the assessment of environmental change. The suite of variables is measured at all ECN sites using published, standard protocols. These protocols are designed to ensure the comparability of the data across the network and form part of the quality assurance procedures in ECN. The published terrestrial and freshwater protocols are also available as books for purchase or citation. These protocols can be viewed using this web interface (as pdf files), where any changes from the published versions (V1) are indicated by underlining. Technical notes are also available where clarification has been needed on aspects of the protocols.
