Description 
Summary

MON*CHEMIE is a part of the Monitoring programme of the National Water Systems (in Dutch: Monitoring Waterstaatkundige Toestand des Lands; MWTL) The primary goal of the MWTL programme is to provide physical, chemical and biological information in relation to long term developments. So the focal point for the monitoring programme is based on trend detection. Another aim is to check the compliance to national and international assessment criteria. The Dutch marine and brackish waters are dived into areas. In field GEOGRAPHIC COVERAGE the area is mentioned. In MON*CHEMIE chemical parameters are determined in surface water, suspended matter, sediment and biota. The starting date mentioned is not necessarily the same for every parameter or location, this can differ from one parameter or location to another. Depending on the parameter and the location most samples are collected on a weekly, monthly or 3 monthly base. The given date is the first year data is available of one or more locations. During the given period more or less locations can be sampled due to changes in the national monitoring programme. Sampling and analysing the samples are carried out by Standard Operating Procedures (SOP's). Nutrients are only determined in watersamples. In general nutrient concentration as Nitrogen and Phosphorus is measured every time a location is visited. For temporal trend purposes the inorganic nutrients are measured during the winter period (December 1st to March 1st). The rest of the year frequency of sampling for nutrients is the same as the frequency of sampling for phytoplankton. (In the winter monthly; during the summer every 2 weeks) For actual planning: www.waterplan.nl
