Site types that use this protocol

The freshwater physical and chemical variables measured in this protocol were selected by ECN because they are expected to indicate the possible causes and consequences of environmental change in the aquatic environment.

Dip samples are analysed for a number of determinands, including major ions and heavy metals, at a recommended frequency of weekly for rivers, fortnightly for lakes.  Continuous pH, temperature, conductivity and turbidity recording is carried out at some sites.  Temperature and dissolved oxygen profiles are measured in lakes.

There are two related protocols described in the attached document:

  • FWC: manual sampling
  • FWA: automatic sampling

Our field activities

AUGUST

At terrestrial sites evening bat monitoring continues and we also sample for spittle bugs using sweep nets. In rivers and lakes we sample aquatic macrophytes (water plants visible to the naked eye). The usual year-round measurements are also made.
