Sentences with phrase «plankton growth in»

This results in intense plankton growth close to the surface, which upon death, sinks on the water column.

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).

CO2 concentrations typically peak in spring, just before trees, plankton and other plants across the Northern Hemisphere awaken from their winter slumber and begin to greedily suck CO2 out of the sky to fuel photosynthesis and the growth of leaves and cells.

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.

Currents rich in nutrients and plankton flow over the ridge, resulting in outstanding growths of sea fans, whip corals and brilliant soft corals.

Such solutions could include developing the possibility of stimulating growth of plankton in the oceans; not with a sporadic and half - hearted science demonstration, but instead, a determined and continuing project to accomplish one of the largest scale real solutions.

Anthropogenic climate change will mean an increased average temperature for the oceans and possible changes in current systems that could locally amplify or reduce warming and can alter nutrient cycling resulting in changes in the amount of nutrients available for the growth of phytoplankton, the plant plankton that are the base of the food chain.

In a paper just published in the Journal of Plankton Research, two Canadian marine scientists, Sonia Batten and James Gower, reported evidence of a critical intervening step — a growth spurt in just the right kind of tiny animals, crustacean zooplankton, that young salmon thrive oIn a paper just published in the Journal of Plankton Research, two Canadian marine scientists, Sonia Batten and James Gower, reported evidence of a critical intervening step — a growth spurt in just the right kind of tiny animals, crustacean zooplankton, that young salmon thrive oin the Journal of Plankton Research, two Canadian marine scientists, Sonia Batten and James Gower, reported evidence of a critical intervening step — a growth spurt in just the right kind of tiny animals, crustacean zooplankton, that young salmon thrive oin just the right kind of tiny animals, crustacean zooplankton, that young salmon thrive on.

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.

[UPDATE: An Australian company with a different technique for boosting plankton growth — adding urea to the sea — has evidently gained permission from the Philippines to do a field test in the Sulu Sea, raising objections from some private groups and bloggers.]

But ocean experts have increasingly warned that the direct chemical impact on marine life, as carbon dioxide dissolves in water and lowers its pH, could profoundly disrupt ecosystems by interfering with the growth of reefs and shell - forming plankton.

Will the increased plankton cause sudden increases in whatever eats it, and then the dwindling larger predators be unable to contain that growth, resulting in later overpopulation and starvation?

It is now well accepted and verified that many biological organisms (e.g., trees, corals, plankton, animals) alter their growth and / or population dynamics in response to changing climate, and that these climate - induced changes are well recorded in past growth in living and dead (fossil) specimens or assemblages of organisms.

Plankton growth is not influenced by increasing CO2 levels, as that is not the limiting factor in seawater (in contrast to land plants).

Plankton forms the main food of many ocean species, and fisheries could be badly hit by the loss of these micro-organisms as a result of warmer waters, according to the paper, published this week in the British journal Nature... Other factors that influence phytoplankton growth include [iron] dust blown from the land, and variations in solar radiation.

Positive effects of climate change may include greener rainforests and enhanced plant growth in the Amazon, increased vegetation in northern latitudes and possible increases in plankton biomass in some parts of the ocean.

The zones form when nutrient - rich waters from the depths rise to the surface and enable a bloom in plankton growth.

Other net negative technologies in development include fertilising the ocean to stimulate the growth of plankton and machines to remove CO2 directly from the atmosphere.

Increased carbon dioxide has already lowered the pH of the surface ocean; this is expected to have a negative effect on survival of plankton, the base of the marine food chain, and the growth and health of corals, which form biodiverse reefs in shallow waters of the Hawaiian Islands and Florida, and deep reefs in Alaska and the Southeast U.S. Invasive species are increasingly being recognized.

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.

It's caused by excess growth in the water of a colorless plankton called «psuedo - nitzchia».

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.
