Since 1998 the Nansen Environmental and Remote Sensing Center (NERSC) in Bergen, Norway has developed, implemented and operated services utilizing satellite EO data for monitoring of harmful algae blooms (HAB) and water quality (WQ) conditions in aquatic areas. Information needs from the growing Norwegian aquaculture industry and management are the prime use of the service.

The service has been developed from use of the NASA SeaWiFS in 1998 and from 2006 to use the ESA MERIS EO sensor, incorporating also data from other satellite EO sensors and forecasts from numerical ocean models.

The EO based service concept is based on both standard products and of in-house processing algorithms tuned to regional water conditions, providing information about the surface distribution of:

All data products are generated as daily images and weekly averages (in order to reduce the impact of the cloud cover limitation.)
