Screening of MSTAT for biota

This document is to help examine whether the classification of stations as baseline (B), representative (RH) and impacted (IH) is reasonable. For the purposes of the MIME assessment:


Original classification

Here are all the biota stations for which a parametric model for at least one chemical determinand. The stations are coloured according to their MSTAT as given in the station dictionary, with the following modifications:

  • Missing values are treated as representative
  • Stations which have ID status (impacted due to dredging) have been turned into representative (because not IH - impacted due to hazardous substances).
  • Stations which have RP status (representative due to physical processes) have been turned into RH./li>

Baseline, representative and impacted stations are coloured blue, green and red respectively. (NB this colour scheme has nothing to do with the status of the chemical concentrations found there; it just reflects the MSTAT values they have been assigned, with blue, green and red provide an intuitive key.)

Revised classification

Here is the revised classification based on discussions at MIME 2015:

Data availability

More station details can be found in MSTAT biota.csv. The column MSTATsubmitted contains the values in station dictionary, MSTATedited contains the minor modifications such as replacing missing values with RH, and MSTAT contains the revised classification based on discussions at MIME 2015.
