In some areas, the amount of plastic outweighs the amount of plankton by a ratio of six to one.

More fresh water in the surface water layers makes it harder for the nutrient - rich bottom water to rise to the upper layers where the sunlight ensures the production of plankton algae in summer.

The simulated ocean acidification led to unexpectedly large changes in the production activity of the plankton with considerable impacts on the release of climate - relevant gases and in turnover rates of important elements in the seawater.

Measuring the level of plankton activity in the ocean is difficult.

The working group on coupled biogeochemical cycling and controlling factors dealt with questions regarding the role of plankton diversity, how ocean biogeochemistry will respond to global changes on decadal to centennial time scales, the key biogeochemical links between the ocean, atmosphere, and climate, and the role of estuaries, shelves, and marginal seas in the capturing, transformation, and exchange of terrestrial and open - marine material.

Another problem with your suggestion (again this is just my opinion) is that you say «significant number of plankton species».

But the instrumental value of plankton for the whole system of life in the ocean is enormous.

In turn, killer whales that feed on seals consume the equivalent of five tons of plankton for each pound of their body weight.12 This phenomenon would explain why Weston Price found seal oil, which he estimated to constitute 200 calories per day of the Inuit diet, to be several times higher in the fat - soluble vitamins than ordinary cod liver oil.30

The metabolic activity and genetic diversity peaked around sea floor layers packed with the remains of plankton called diatoms, which presumably provide the carbon and other nutrients for the more complex ecology.

But dictating the species composition of a plankton bloom and its aftermath remains beyond the ken of marine biology, causing one researcher involved in the successful 2004 effort, marine biologist Victor Smetacek of the Alfred Wegener Institute for Polar and Marine Research in Germany, to call it beyond control at this stage.

According to a 2006 report from the U.N. Environment Programme, every pound of plankton in the central Pacific Ocean is offset by about 6 pounds of litter.

Greater numbers of bugs could also deplete populations of the plankton they feed on, throwing a wrench into the ecosystem, Goldstein adds.
