Sentences with phrase «plankton growth»
Plankton growth refers to the increase in tiny organisms (plankton) in oceans, lakes, and other bodies of water. These organisms, like algae and small animals, are vital for the health of marine ecosystems and serve as food for many larger creatures. So when we talk about plankton growth, we mean the population of these small organisms getting bigger. Full definition

The WeatherBird II was the centerpiece of a now - halted project aimed at encouraging plankton growth.
In his letter on ocean thermal energy conversion (OTEC), Graham Cox suggests it could be used to fertilise surface waters with nutrient - rich deep water to promote plankton growth for carbon capture (1 December, p 31).
«Global fisheries to be, on average, 20 percent less productive in 2300, UCI study finds: Warming - induced plankton growth near Antarctica will impair marine food chain.»
Stronger winds drive increased upwelling, bringing nutrients to the surface, resulting in higher nutrient concentrations and more plankton growth near Antarctica.»
Oceaneos's experiment will probably increase plankton growth in low - iron waters, Marchetti says, «but it's not to say that that is actually good for the higher levels of the food chain».
The oft - cited potential coastal hazard is in fact pretty illusory, since most coastal waters are iron - replete, and adding further iron therefore produces no new plankton growth at all.
Hamme says the team's preliminary analysis suggests that trying to stimulate plankton growth by adding iron to the water would have a minuscule effect on marine CO2 absorption.
The vents spew out substances from deep within the Earth's crust, including iron, a metal known to seed plankton growth.
«Combined with warmer ocean temperatures throughout the year, this leads to a longer growing season and faster plankton growth rates.
Moore and his fellow researchers used an empirical model linking plankton growth to present - day fish catches and then factored in dwindling nutrients and plankton populations due to climate warming in the coming centuries.
This results in intense plankton growth close to the surface, which upon death, sinks on the water column.
However, current understanding suggests that, unless substantial ocean circulation changes occur, plankton growth remains roughly unchanged because it is limited mostly by environmental factors, such as nutrients and light, and not by the availability of inorganic carbon it does not contribute significantly to the ocean uptake of anthropogenic CO2.
At the same time, a decline in sea ice caused increased windiness; this created more mixing in the ocean, further slowing plankton growth.
Fewer clouds mean more sunlight, spurring greater plankton growth.
The resulting plankton bloom, which registers a relatively more «green» color shown as «red» on the satellite image, is associated with luxuriant plankton growth induced by a dispersion of dilute iron sulfate, at around 200ppm.
However, whilst many studies have had success promoting plankton growth, few have seen an increase in the amount of carbon transported to the sea bed.
With this methodology, the factors most often mentioned as risks of negative or unintended consequences are a.) employing it too near coastal zones afflicted with toxic algal species, and b.) pushing beyond literal «restoration» activities to seed unprecedented concentrations of new plankton growth.
Planktos are attempting to create a carbon offset product based on stimulating plankton growth.
Along with a boosted catch, a second hoped - for payoff was the sale of carbon credits on international markets aimed at offsetting greenhouse gas pollution by financing projects that absorb heat - trapping carbon dioxide — typically by planting trees but in this case through spurring plankton growth.
Another high - profile test — of dumping iron particles into the ocean to stimulate plankton growth — failed miserably after being disrupted by protesters.
In his letter, Alec Dunn suggests that pumping nutrient - rich deep ocean water to the surface would stimulate plankton growth and...
You report on a successful trial of ocean iron - seeding to promote plankton growth and potential carbon sequestration via the sinking...
Your article on adding iron to patches of ocean to encourage plankton growth and so capture atmospheric carbon (21 July,...
In his letter, Alec Dunn suggests that pumping nutrient - rich deep ocean water to the surface would stimulate plankton growth and hence capture atmospheric carbon (18 August, p 32).
Without iron there would be no plankton growth, no food chain, no photosynthesis and no carbon fixation in the oceans.
This has led to suggestions that we should fertilise the oceans with iron to promote plankton growth and stem climate change.
Only when we know when and where certain nutrients are available for plankton growth we can also estimate how much carbon the plankton can bind by photosynthesis and thus remove from the atmosphere.»
The result is a dramatic rise in sea - surface temperature and a drastic decline in plankton growth, which is devastating to the marine food chain, including commercial fisheries in the region.
Iron — a nutrient naturally carried into the ocean by wind — encourages plankton growth, which can absorb atmospheric CO2, a greenhouse gas.
The zones form when nutrient - rich waters from the depths rise to the surface and enable a bloom in plankton growth.
I've written — been writing about this in relation to iron fertilization, efforts to pour iron dust into the sea and stimulate salmon runs and plankton growth.
More sea ice means less ocean mixing, which also encourages plankton growth.
A dozen early experiments in different regions have shown that plankton growth increases when iron is artificially added, but scientists have yet to show that this could lock significant amounts of CO2 into the ocean; carbon from the plants would have to sink to the bottom for this to happen.
