iron fertilization

The side effects of large-scale iron fertilization are not yet known.

He also applied the technology to enable iron fertilization experiments.

The iron fertilization scheme has been criticized on several fronts.

Iron fertilization of the ocean has been proposed as a way to limit climate warming.

Ocean iron fertilization is an example of such a geoengineering technique.

Ocean iron fertilization has been given small-scale research trials.

This produces results somewhat similar to iron fertilization.

However, controversy about manipulating the ecosystem and the efficiency of iron fertilization has slowed such experiments.

Numerous experiments have been carried out demonstrating how iron fertilization can increase phytoplankton productivity.

Iron fertilization attempts to encourage phytoplankton growth, which removes carbon from the atmosphere for at least a period of time.

The potential of iron fertilization as a geoengineering technique to tackle global warming is illustrated by the following figures.

While ocean iron fertilization could represent a potent mean to slow global warming current debate raises a variety of concerns.

These poor sequestration results have caused some to suggest that ocean iron fertilization is not an effective carbon mitigation strategy in general.

Iron fertilization - proposed fertilization of oceans to stimulate phytoplankton growth.

Nitrogen fertilization is not as efficient as iron fertilization.

Iron fertilization is the intentional introduction of iron to the upper ocean to stimulate a phytoplankton bloom.

In recent years, Chisholm has played a visible role in opposing the use of iron fertilization as a technological fix for anthropogenic climate change.

Critics and advocates generally agree that most questions on the impact, safety and efficacy of ocean iron fertilization can only be answered by much larger studies.

The uncertainties are so large that the piece suggests that it's not even clear whether iron fertilization even produces a net reduction in atmospheric carbon.

Bio-energy with carbon storage, afforestation projects, and ocean nourishment (including iron fertilization) could be considered examples of bio-geoengineering.

It has been proposed that iron fertilization of the ocean could stimulate photosynthesis in phytoplankton (see Iron Hypothesis).

This has led to some scientists advocating iron fertilization as a means to counteract the accumulation of human-produced carbon dioxide (CO) in the atmosphere.

He is also known for advocating the use of iron fertilization to enhance oceanic primary production to act as a sink for fossil fuel carbon dioxide.

Stimulating the Ocean Biological Carbon Pump by Iron Fertilization - Jun Nishioka, 2003.

By comparison, other geoengineering techniques based on greenhouse gas remediation, such as ocean iron fertilization, need to sequester the anthropogenic carbon excess before they can arrest global warming.
