Sentences with phrase «on iron fertilization»

Based on a century of ocean plankton science and the 10 international experiments on iron fertilization over the last 15 years we are confident that the scale, methods and technologies of the work we are planning will have positive impacts on all fronts, improving water quality, buffering surface water acidity, recharging the marine food chain, and safely sequestering enormous amounts of CO2 to help slow climate change.

Think Again... Where We Stand on Iron Fertilization

GreenSea Venture, the company started by Markels, remains very focused on iron fertilization as a sequestration strategy.

Markels took out at least seven patents on iron fertilization strategies and set up a company now called GreenSea Ventures.

But the change in carbon chemistry of the ocean and ultimately the atmosphere need to be transparently documented, also, if we are to trade carbon offsets based on iron fertilization.

Not exact matches

(Iron fertilization enthusiasts focus on the Southern Ocean because other seas have much more natural algae, so growing blooms might just foster growth that would have happened anyway.)

In that project, US entrepreneur Russ George convinced a Haida Nation village to pursue iron fertilization to boost salmon populations, with the potential to sell carbon credits based on the amount of CO2 that would be sequestered in the ocean.

Possible mechanisms include (iv) fertilization of phytoplankton growth in the Southern Ocean by increased deposition of iron - containing dust from the atmosphere after being carried by winds from colder, drier continental areas, and a subsequent redistribution of limiting nutrients; (v) an increase in the whole ocean nutrient content (e.g., through input of material exposed on shelves or nitrogen fixation); and (vi) an increase in the ratio between carbon and other nutrients assimilated in organic material, resulting in a higher carbon export per unit of limiting nutrient exported.

Paul Beckwith has done both a blog and a You tube video on the possibilities of iron fertilization to reduce carbon in the atmosphere.

If I did, I'd drop $ 200 million on Bussard (I'm sure he'd enjoy that); $ 200 million on kickstarting a vertical farming industry, the same on ocean iron - fertilization studies, another chunk on developing an agrichar infrastructure, and the rest on various projects that can't get funding because they have a low probability of success, but massive payoff if they do work.

What are your views on experiments testing whether fertilization of mineral - starved regions of the oceans with iron could serve to pull carbon dioxide out of the atmosphere?

This result sheds new light on the effect of long - term fertilization by iron and macronutrients on carbon sequestration, suggesting that changes in iron supply from belowâ as invoked in some palaeoclimatic and future climate change scenarios11â may have a more significant effect on atmospheric carbon dioxide concentrations than previously thought.

Paul Beckwith has done both a blog and a You tube video on the possibilities of iron fertilization to reduce carbon in the atmosphere.

The simple fact is that while iron fertilization experiments have been taken place for nigh on twenty years thanks to the late John Martin's iron hypothesis, none of these experiments have lasted long enough or been conducted on a large enough scale to effectively measure the entire life of a pleagic phytoplankton bloom, artificially fertilized or naturally occuring.

EFFECT OF NATURAL IRON FERTILIZATION ON CARBON SEQUESTRATION IN THE SOUTHERN OCEAN Nature, Vol 446 26 April 2007 doi: 10.1038 / nature05700 The efficiency of fertilization, defined as the ratio of the carbon export to the amount of iron supplied, was at least ten times higher than previous estimates from short - term blooms induced by iron - addition experimeIRON FERTILIZATION ON CARBON SEQUESTRATION IN THE SOUTHERN OCEAN Nature, Vol 446 26 April 2007 doi: 10.1038 / nature05700 The efficiency of fertilization, defined as the ratio of the carbon export to the amount of iron supplied, was at least ten times higher than previous estimates from short - term blooms induced by iron - addition experimeiron supplied, was at least ten times higher than previous estimates from short - term blooms induced by iron - addition experimeiron - addition experiments.

In that project, US entrepreneur Russ George convinced a Haida Nation village to pursue iron fertilization to boost salmon populations, with the potential to sell carbon credits based on the amount of CO2 that would be sequestered in the ocean.

Since plankton account for 50 % or so of the carbon recycling on the planet (plus permanent carbon sequestration if the iron fertilization hypothesis is right) doesn't this mean that CO2 - induced acidification would accelerate the rate of CO2 increase in the atmosphere, which would then accelerate the rate of acidification?

On the heels of my last post about iron fertilization of the ocean, I found another interesting paper on the topiOn the heels of my last post about iron fertilization of the ocean, I found another interesting paper on the topion the topic.

We should not risk iron fertilization on the scale needed to affect global CO2 levels or animal populations.

The climate feedbacks involved with these changes, which are key in understanding the climate system as a whole, include: + the importance of aerosol absorption on climate + the impact of aerosol deposition which affects biology and, hence, emissions of aerosols and aerosol precursors via organic nitrogen, organic phosphorus and iron fertilization + the importance of land use and land use changes on natural and anthropogenic aerosol sources + the SOA sources and impact on climate, with special attention on the impact human activities have on natural SOA formation In order to quantitatively answer such questions I perform simulations of the past, present and future atmospheres, and make comparisons with measurements and remote sensing data, all of which help understand, evaluate and improve the model's parameterizations and performance, and our understanding of the Earth system.
