Winds play a strong role in the distribution of phytoplankton because they drive currents that cause deep water, loaded with nutrients, to be pulled up to the surface.These upwelling zones, including one along the equator maintained by the convergence of the easterly trade winds, and others along the western coasts of several continents, are among the most productive ocean ecosystems.
With warm, buoyant water on top and cold, dense water below, the water column doesn't mix easily. Phytoplankton blooms, primarily of diatoms, occurred in the lower estuary during August 1965 and 1966.

Productivity is expected to drop because as the surface waters warm, the water column becomes increasingly About 70% of the ocean is permanently stratified into layers that don’t mix well. They consume carbon dioxide, and release oxygen. Phytoplanktons are the base of the aquatic food web.

E. huxleyi is an abundant species of coccolithophore. Phytoplankton can grow explosively over a few days or weeks. (NASA image by Jesse Allen & Robert Simmon, based on SeaWiFS data from the GSFC El Niño events influence weather patterns beyond the Pacific; in the eastern Indian Ocean around Indonesia, for example, phytoplankton productivity increases during El Niño. The most common kind of phytoplankton is the It is believed that phytoplankton photosynthesis only produce half of the planet's air for breathing, but if you think about it, our ocean covers 71 percent of the Earth. Sampling devices include hoses and flasks to collect water samples, and sometimes, plankton are collected on filters dragged through the water behind a ship.Marine biologists use plankton nets to sample phytoplankton directly from the ocean.

J Coastal Res, China. Phytoplankton are tiny, plant-like organisms that often float near the ocean surface and turn sunlight and carbon dioxide into sugars and oxygen. (Graph adapted from Over the past decade, scientists have begun looking for this trend in satellite observations, and early studies suggest there has been a small decrease in global phytoplankton productivity.

Like plants on land, phytoplankton growth varies seasonally. As upwelling declines, populations of larger phytoplankton such as diatoms are predicted to decline (green line). While blooms can provide more food to organisms higher up the food chain, too much phytoplankton can also do harm.

J Geophys Res 104(C9):20675–20686. If there is a bloom, the phytoplankton and other aquatic organisms (like fish) can consume more oxygen than is produced. They are abundant in cold, nutrient rich waters where they form the base of the food web, and are an extremely diverse and varied group of organisms.
