A one-week field campaign was held at the end of June on the Elbe River, starting from just before Hamburg and ending at the river mouth in Cuxhaven, to gather samples at different stations along the river, and at less sampled areas of the river.
The CERTO field campaign was organised by University Stirling with the consultancy of Brockmann Consult, the Certo Elbe Case Study Site lead. Hereon (formerly HZG), the local advisor board member, provided great technical and infrastructure support, and permitted CERTO to run the campaign on their ship, the RV Ludwig Prandtl. One scientist from Stirling University participated in the campaign along with three other colleagues from Hereon.
Instruments from University Stirling, including a Trios radiometer system, were shipped in advance, and mounted on board the Prandtl for the 5-day campaign, alongside Hereon’s own equipment. This allowed a cross-comparison of the different radiometric sensors.

Alongside radiometric measurements, the waters were also sampled for total and inorganic suspended matter, chlorophyll-a, and Secchi depth. Other parameters such as temperature and wind were also measured.
