The Value of High-Resolution In Situ Time Series Data for Ocean Colour Validation in the North Sea
CEFAS, UNITED KINGDOM
There is a long history of pelagic research in the shelf seas of the British Isles and in the North Sea in particular. Long-term trends in phytoplankton biomass can be derived from various proxies such as greenness from the Continuous Plankton Recorder, in situ chlorophyll, ocean colour chlorophyll, and more recently with predictions from biogeochemical models such as ERSEM. These measures all differ, and I will attempt to reconcile the differences in this presentation, whilst demonstrating that high frequency in situ time series data from fixed platforms are the most cost-effective means of providing validation data for remote sensing.
