Waterbase - TCM: QualityBiota

Data Table

This page was archived on 26 Jun 2015 with reason: Other (New version data-and-maps/data/waterbase-transitional-coastal-and-marine-waters-11 was published)

The QualityBiota table contains aggregated data on hazardous substances in biota, measured at Eionet-Water transitional, coastal or marine water monitoring stations, provided by national sources or Marine Conventions. Each station has been assigned a unique Waterbase identifier (WaterbaseID) which can be used to link the Quality data with their respective Stations and Pressures data.
