Hayley Evers King (EUMETSAT): Satellite ocean colour: what does colour really tell us about our seas?
Hayley Evers King shows how to interpret ocean colour and talks about different information we can obtain from satellite derived measurements.
Satellite-based measurements of ocean colour quantify the visible light reflected from the ocean surface. These data represent the interactions between light from the sun and the various constituents that can be present in our ocean waters. As such, this signal can be 'decoded' by a range of techniques to provide information on these constituents. This presents an evolving array of societally relevant applications, from fisheries and aquaculture management, to water quality warnings, and climate reporting. This presentation will cover some fundamentals of ocean colour theory, current missions and products, and examples of this data in use.
