6.1 Mandatory and optional subprogrammes
In addition to the mapping requirements presented in Chapter 5, the minimum level of the IM programme is presented in Table 6.1. This common minimum level of the programme is required in order to allow evaluation of data at the international scale regarding the priority topics of the IM programme. Table 6.1 also includes recommendations for sampling frequency. Depending on national priorities and available resources the subprogrammes which are marked optional may or may not be carried out. A table of parameters measured in individual subprogrammes is presented in Table 6.2.
