Session: New satellite sensors and algorithms 
Coastal areas are of high ecological and economic value, however they are subjected to 
intense human-induced environmental pressures. An effective monitoring system is therefore vital for 
the operational management and safeguarding of the coastal areas. Traditional in-situ sampling can be 
very labour-intersive and often doesn’t cover the whole area at once. Satellite imagery can fill this gap. 
Typical ocean colour satellites have a spatial resolution of 250-300 m  (e.g. MODIS 250 m channels, 
MERIS, Sentinel-3). Although ideal for a lot of applications, this can be insufficient for the monitoring 
of small scale features in near shore areas such as port or estuaries. The remote sensing community has 
already been looking to some extent into the usage of non-ocean-colour sensors to include these small 
features. Examples include Landsat, Sentinel-2, SEVIRI, Deimos and Formosat.   This work shows the 
suitability of the Proba-V sensor (spatial resolution of 100 m) for the retrieval of water quality 
parameters. Proba-V was neither conceived as an ocean colour mission, but its specifications (spectral 
bands and signal-to noise ratio) allow to monitor the turbidity. Proba-V derived turbidty products, 
atmospherically corrected with an adapted version of iCOR (De Keukelaere et al. (Submitted)) and a 
modified version of Nechad et al. (2009), are compared with continuous buoy measurements (CEFAS 
Smartbuoys) and cross-validated with MODIS aqua products.      References De Keukelaere, L.,
