Citclops water colour and transparency measurements from kayaks in the NW Mediterranean

Within the PAGAIA symposium for sea kayakers in the Catalonian coastal village of Llanca, a Citizen training event was organised by Citclops project partners of the Institute of Marine Science (ICM-CSIC) in Barcelona and University of Oldenburg & Institute for Chemistry and Biology of the Marine Environment (ICBM) in Oldenburg, and by the two kayak groups Salzwasser UNION e.V. – Verband der Seekajakfahrer e.V., Germany & PAGAIA Club de Caiac Cap de Creus, Llanca.

After a theoretical introduction on 31 March at the kayker´s symposium base camp in Llanca by scientists from Oldenburg and Barcelona, a field trip was planned for the next day.
Due to harsh weather conditions on site, the tour had to be re-located 200km south to Platja Canyelles. Nonetheless, a small group of scientists and kayakers faced the challenge and could provide photos of the water colour with different camera types which flow into the Citclops data pool for data validation (http://citclops.eu/participate/upload-your-image). The water in the coastal area was very clear (Secchi > bottom depth, approx, 15 m) and of greenish blue colour (around 5 on the Forel Ule colour comparator scale). In addition, the Citclops affordable water transparency device KdUINO was installed for measurements in the coastal area. In addition, first field samples were collected and measured with the new Citclops smart phone fluorescence sensor.
The next trip with kayakers in Spain is already planned!
