An unprecedented analysis of Harmful Algal Bloom (HAB) events worldwide launched by UNESCO's IOC

The first-ever global statistical analysis examined roughly 9,500 HABs events over 33 years and found that the harm caused by HABs rises in step with growth of the aquaculture industry and marine exploitation and calls for more research on linkages. The analysis uses regional trends of microalgal observations in OBIS as a proxy for monitoring effort.
