Time series analysis of algal blooms in Lake of the Woods using the MERIS maximum chlorophyll index

摘要

The MERIS (MEdium Resolution Imaging Spectrometer) maximum chlorophyll index was applied to Lake of the Woods, an inland water body under significant water quality pressure from recurring cyanobacteria blooms, in order to address the commonly raised concern that blooms on the lake have increased recently. Recent trends in bloom characteristics (intensity, timing and aerial extent) were analysed in relation to local climate variables, offering important new insights into the mechanisms driving algal bloom occurrences on the lake.
