Monitoring methodology

Monitoring of water clarity in the Contracting Parties of HELCOM is described on a general level in the HELCOM Monitoring Manual in the sub-programme Water column hydrological characteristics.

Monitoring guidelines specifying the sampling strategy are adopted and published.


Current monitoring

The monitoring activities relevant to the indicator that are currently carried out by HELCOM Contracting Parties are described in the HELCOM Monitoring Manual Sub-programme sub-programme Water column hydrological characteristics: Monitoring concepts table.


Description of optimal monitoring

The regional monitoring effort is considered sufficient to support the indicator evaluation.
