Seabed and sea surface light time series measurements collected in the Bay of Brest, Brittany, France.

Seabed and sea surface light time series measurements (and associated water depth and temperature records) collected in the Bay of Brest, Brittany, France, for a project studying the effect of the tide on seabed light.

These data were collected as part of a project studying the effect of tidal variations in water depth and clarity on the light that reaches the seabed (Roberts et al., 2014; Roberts, 2015). They were collected in the Bay of Brest, Brittany, France, in 2011-2012 by Bangor University scientists (primarily E.M. Roberts), assisted by contacts at the Centre d'Etudes Techniques Maritimes et Fluviales (CETMEF, now Cerema) and the Institut Universitaire Europeen de al Mer (IUEM). R.V. Albert Lucas, and smaller vessels, were used for deployment and recovery of the instrumentation. Corresponding time series records of seabed and sea surface irradiance were collected. Water depth above, and water temperature at the position of, the seabed light sensor were also recorded.
