This dataset contains turbidity, chlorophyll and the associated sensor raw data between the 15th of January 2020 and the 15th of June 2020 on EMSO-Canarias (a.k.a. ESTOC) observatory by the EGIM. Turbidity is one of the 7 core parameters monitored by the EGIM, EMSO Generic Instrumental Module. The EGIM prototype was deployed at the ESTOC site at 3580m depth, 100km North of Gran Canaria, to monitor local hydrodynamic variability and complement the data obtained by the ESTOC station.
