HABs also include blooms of non-toxic species that have harmful effects on marine ecosystems. For example, when masses of algae die and decompose, the decaying process can deplete oxygen in the water, causing the water to become so low in . Introduction. Ocean phytoplankton generate almost half of global primary production , making it one of the supporting pillars of marine ecosystems, controlling both diversity and lankton in temperate and subpolar regions are characterized by spring blooms, a seasonal phenomenon with rapid phytoplankton biomass accumulation due to a high net phytoplankton .
Keywords: Harmful algal blooms, human health and wellbeing, marine biotoxins, ecosystem services OVERVIEW OF THE CHALLENGES Aquatic ecosystems are supported by photosynthetic organisms (e.g. macrophytes, benthic and planktonic microalgae and cyanobacteria) that fix carbon, produce oxygen, and constitute the base of food webs. Some red tides are associated with phytoplankton that produce toxins, but fortunately for San Francisco Bay the algal bloom dissipated within a week before any harmful effects occurred. Water-resource managers worldwide are dealing with algal blooms, red tides, eutrophication, and other problems associated with phytoplankton in coastal ecosystems.
Phytoplankton can also be the harbingers of death or disease. Certain species of phytoplankton produce powerful biotoxins, making them responsible for so-called “red tides,” or harmful algal blooms. These toxic blooms can kill marine life and people who eat contaminated seafood. There is some evidence that marine bioaerosols containing cyanobacteria and microalgae may be harmful to human health. Phytoplankton can absorb and accumulate a variety of toxic substances, such as methylmercury, polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons.

Although algal blooms, including those considered toxic or harmful, can be natural phenomena, the nature of the global problem of harmful algal blooms (HABs) has expanded both in extent and its public perception over the last several decades.
Of concern, especially for resource managers, is the potential relationship between HABs and the accelerated eutrophication of coastal waters from human. Phytoplankton growth is often limited by the scarcity of iron in the ocean.
As a result, many people are discussing plans to fertilize large areas of the ocean with iron to promote phytoplankton blooms that would transfer more carbon from the atmosphere to the deep sea. Phytoplankton are critical to other ocean biogeochemical cycles, as well.

Eutrophication as one of the importunate environmental hazards in the aquatic ecosystems causes pronounced deterioration of the water quality and represents serious threat to the biotic components of this ecosystem.
The main environmental effects of eutrophication are increase of suspended particles owing to extensive macroalgal blooms, decrease of water clarity.
Harmful algal blooms (HABs) have been investigated for their catastrophic effects on public health and aquaculture intensively, but the research about HABs effects on the diversity patterns and intrinsic functions of the plankton community based on a species identification with high resolution and accuracy has been scarce.

Marine microalgae are primary producers and constitute key components of marine food webs: they fix carbon and produce nearly 50% of the oxygen on the planet (Field et al., ).Most phytoplankton communities are directly affected by human activities, especially through the excess inputs of organic matter and nutrients to the system (Hallegraeff, ), usually linked to high.

Harmful algal blooms are caused by high concentrations of certain free-floating single-celled plants in the ocean (known as phytoplankton) that produce toxins that spread into the marine ecosystem.
Of approximately 5, known species of phytoplankton (microalgae), only a few dozen are known to produce toxic chemicals that can harm fish, shellfish, marine mammals, seabirds, and humans.As the causes and effects of macroalgal blooms are similar in many ways to those associated with harmful phytoplankton species, scientists use the term harmful algal bloom (HAB) to describe this diverse array of bloom phenomena.
Many studies have addressed the importance of nutrient loading to the development of macroalgal HAB. Paerl H.
