An investigation of the potential use of ocean colour remote sensing to assess the influence of variations in freshwater inputs to coastal ecosystems
Expanded Title:The preliminary findings of the study show that ocean colour remote sensing provides a unique means of assessing the effects that variation in freshwater influxes have on the coastal marine environment , as it provides a cost-effective ability to routinely provide quantifiable synoptic data of phytoplankton biomass and production, as well as fluctuations of sediment and dissolved organic material from riverine input. Specifically, the MERIS C2R algorithm provides optimal products in Case 2 waters, but the default atmospheric correction and “Algal 1” in-water products will serve users better in offshore Case 1 waters. Validation data have been gathered in 2009 and 2010, and these will form the basis for providing error products along with geophysical products routinely in the region – an important step in the effective utilisation of the ocean colour data in climate-related time series analyses.
