Metadata

Methodology:: The map is based on a .dbf file named after its season-location (e.g. wintermeans_baltic.dbf containing winter Nitrate and Nitrite values from the Baltic Sea, incl. longitude/latitude by station). The name location part of the name has an "OW" fix if it contains Open Water data, otherwise data are form coastal stations. The column N₅N or PO₄ is used for wintermeans maps. The colours of the legend are based on the 20%, 40%, 60% and 80% percentiles of the indicator presented.

Additional information

Only stations with more than two years data are included. Coastal stations are marked by circles and ICES open-water stations (>20 km from coast) by squares. Level of classification is based on the 20 % 40 %, 60 % and 80 % percentiles of the indicator presented.
