Harmful Algal Bloom
Definition
Harmful algal blooms (HABs) are proliferations of certain noxious and/or toxic micro- and macroalgae and cyanobacteria, regardless of their concentration, with negative impacts on aquatic ecosystems, and human health and wellbeing. HABs are naturally occurring phenomena that are also facilitated by anthropogenic pressures (including eutrophication, habitat modification and introduction of exogenous HAB organisms). HABs constitute a complex global problem that might increase in severity and frequency, and be expanded in biogeographic range, in our changing planet (GlobalHAB).

Publishing institution: Copernicus
The Copernicus Marine Environment Monitoring Service provides various products and services for marine applications.
These include a global ocean physical analysis and forecast, biogeochemistry analysis and weekly forecast, global ocean waves analysis and forecast and in-situ observations.
To the parameters observed belong: temperature, salinity, chlorophyll concentrations and many more.
Publishing institution: National Oceanic and Atmospheric Administration (NOAA)
NOAA's Ecoforecasting Map locates site at risk of HABs, names prevalent species at the site and links directly to Alerts and Bulletins (forecasts) for the respective regions.
The HABS Data Portal, is the portal for the great lakes (Lake Erie) mapping in-situ data useful in mapping algal blooms in the region.
The phytoplancton monitoring network is a webmap which includes current weather radar, sampling locations and oceanographic data (SST,Salinity)

The World Water Quality Information and Capacity Building Portal (IIWQ) is a webmap that illustrates data on turbidity, chlorophyll-a, total absorption as well as the EOMAP specific harmful algal bloom indicator (HAB indicator). Where access to in-situ data is available station values are presented.

Publishing institution: Regional Organization for the Protection of the Marine Environment (ROPME)
The ROPME has initiated a regional program and special remote sensing unit for routine monitoring of marine and coastal environments in its regional marine area (the Gulf, Sea of Oman and Arabian Sea), which is conventionally, known as ROPME Sea Area.
This program relies essentially on processing and utilization of real-time and near-real time satellite data from NASA’s MODIS sensor that is being received through the MODIS Direct Broadcast Receiving Station. This station has been installed at ROPME Secretariat in Al-Jabriya, Kuwait in early 2003 and still operative since that data. The station is being operated and managed by the experts of the Remote Sensing Unit (RSU) and routinely receives satellite data only from MODIS sensor onboard Terra and Aqua satellites.
The RSU also provides a guidance and advice to the national focal points and other concerned authorities in case they need further information on status of the marine environment in their territorial waters or...

Set of maps developed by the Harmful Algal Studies Center (CREAN) of the Fisheries Development Institute (IFOP), whose purpose is to show the relative abundance of the Alexandrium catenella microalga, with the aim of informing and alerting about the presence of this dinoflagellate harmful. This information is preventive and in no case determines the opening and closing of seafood extraction areas.
Publishing institution: Copernicus
The map indicates chlorophyll-A and sea surface temperatures in the North Atlantic based on data.
