The Department of Fish and Wildlife also tracks exposure of marine birds and mammals to these toxins. The team looked at how motile phytoplankton are affected by hydrodynamic flows. Page view counter started counting on: 8. Plankton (including phytoplankton and zooplankton) are the foundation of the oceanic food web and remain highly sensitive to physical and chemical factors in the, One group of phytoplankton, known as coccolithophorids, release significant amounts of dimethyl sulfide (DMS) into the atmosphere. The organisms also play a key role in regulating atmospheric carbon dioxide levels. "https://secure." Like land plants, phytoplankton require inorganic nutrients such as nitrates, phosphates, and sulfur which they turn into proteins, fats, and carbohydrates. Dinoflagellates, whose bodies are covered with complex shells, are particularly interesting because they can create energy from both sunlight and from the ingestion of organic prey. NOTE: It’s not clear exactly how much carbon makes it to the ocean floor. When the waters stratify, phytoplankton are trapped near the surface, forming a bloom. Since the 1990s, blooms of blue-green algae (also called cyanobacteria) have increased in frequency and abundance, sometimes producing toxins called microcystins. Algae can grow to excessive numbers after an upwelling ends, winds die down and the surface waters warm and stratify. One teaspoon of seawater may contain as many as 50,000 tiny algae. These nasty, smelly filamentous mats on the surface of the water can lead to fishing frustration and reduced aesthetics, and can negatively impact recreational activities like swimming and boating.

Phytoplankton are microscopic algae that live near the surface of oceans and lakes. HABs can also contaminate seawater used to produce freshwater for humans; climate change is expected to exacerbate this problem. Ghosh, T., Paliwal, C., Maurya, R., and Mishra, S. 2015.

They also need tiny amounts of iron, whose scarcity hinders phytoplankton growth in many areas of the ocean.

“The fact that there is a patchy distribution of phytoplankton on a kilometre scale can be easily understood and explained by oceanic currents and strong winds. To assess the phytoplankton behaviour on a sub-centimetre scale, the researchers combined 3D particle dynamics simulations with Navier–Stokes equations.
