Two 2-week deployments at the Billia Croo (BC) wave site were carried out (typically 3–5 m wave height). The first in a tidally influenced area with up to 3.5 m/s spring tides. The second was at a non-tidally influenced area of the wave site with up to 1.5 m/s spring tides.
The FLOWBEC device was deployed at the tidally influenced site from 10 Jul – 24th Jul 2013 and at the non-tidally influenced site from 27 Jul – 12 Aug 2013.
The FLOWBEC platform had a WET Labs ECO FLNTUSB fluorometer positioned with an upwards orientation.
The fluorometer measures turbidity and fluorescence, which can be used as a proxy for phytoplankton. The fluorometer provides contextual data on biomass/productivity in the water column testing the hypothesis formed at the EMEC tidal energy sites that the advection of productive water masses into the area may signal the arrival/presences of many other species. Measures of turbidity/visibility can be used to predict the perceptual range of animals that may impact and predict the behaviour of species around devices.
