A Triumph For MERIS: Monitoring Of Blooms And Vegetation Using The Global MERIS MCI Data Set
Abstract
The Maximum Chlorophyll Index (MCI) has successfully demonstrated a new way to monitor floating and near-surface vegetation and intense surface plankton blooms in coastal and ocean waters. MERIS MCI shows some blooms in which high radiance at 709 nm is the dominant feature of their optical spectrum. Such blooms would not be detectable without a band at this wavelength. The 10-year dataset is unique to MERIS in that the 709 nm band is not included in other wide-swath water-colour imagers such as MODIS, SeaWiFS or VIIRS. We have used the MERIS data to show patterns of pelagic Sargassum never before seen from space, an increasing trend of Antarctic “superblooms,” and details of the global distribution of Trichodesmium and other blooms. In this paper we show examples from the full global MCI dataset compiled during a joint ESA (GPOD) and Canadian Space Agency project.
