Dissolved inorganic nitrogen HOLAS 3

This dataset contains results on HELCOM Assessment unit level 4b for dissolved inorganic nitrogen.


The information provided represents the data and results from the HELCOM HOLAS 3 indicator evaluation for eutrophication, covering the data period from 2016-2021. Data reported from national monitoring programmes to the HELCOM COMBINE database (hosted by ICES) is utilized for open sea assessment units. Open sea data extraction is carried out by ICES for in-situ (bottle) data creating the underlying assessment dataset [link ]. Coastal assessment units (WFD water types or water bodies) are assessed based on WFD result data reported by countries.


Indicator analysis of both open sea and coastal areas is carried out using the HEAT assessment tool ( https://github.com/ices-tools-prod/HEAT).


This analysis provide the basis of the HELCOM indicator evaluations and are utilized in the HOLAS 3 thematic assessment of eutrophication.
