Microalgae are disappearing from the oceans !? 3

Phytoplankton are tiny plants that provide the foundation for the entire marine ecosystem.

They supply nutrients and energy to zooplankton, the smallest creatures in the ocean. Zooplankton, in turn, feed fish and other marine life.

Phytoplankton also absorb carbon dioxide and produce oxygen. Scientists say that much of the oxygen in our atmosphere was produced by plant plankton, though photosynthesis, over the past 2 billion years.

They are disappearing at the rate of 40 percent since 1950, and drop by about 1 percent every year. Phytoplankton is the basic currency for everything going on in the ocean,

It's bad news for all creatures that rely on the oceans for food ? from fish to whales to seabirds. Our fish stocks, which are already affected by overfishing and climate change, will diminish further if the decline continues. And there will be fewer plants to absorb the harmful CO2 in our atmosphere.

We can either act on it or we can rely on nature.

We can expect nature to set things right at the appropriate time.
When CO2 levels go up even more, may be we will find
phytoplankton growing all over, on either side of the roads, in our backyards, lawns, etc to utilising the CO2 to grow.

Take corrective action now.

REad more from the week.

    has posted a blog suggesting the following action.

    A wind powered method for passive de-acidification of the oceans.

    By using a floating, wind driven apparatus, to inject pressurized ambient air at a given depth, the dynamic we are manufacturing artificially is that of, crashing waves, or an artificial wave action. That is the only function of this device. The rate at which it functions is directly dependent on wind speed.

    When artificial wave action begins a number of interesting things begin to occur.

    As the bubbles rise, the air within exchanges some gasses with the seawater and will also be saturated with water vapor to 100% RH. As the air bubble reaches the surface it will contain more water vapor by volume than in the ambient air.

    This overall increase in ambient humidity will eventually result in increased rainfall somewhere.

    By deploying large numbers (TBD) of this floating apparatus as a test by for example: dotting the Mississippi River Estuary, even miles out to sea the effects on the Gulf of Mexico's eutrophic estuarial dead zones will be significant and immediate.

    The increased oxygen levels from the simulated wave action. As the "wet" air mass in the atmosphere increases, eventually this extra "distilled" fresh water in the atmosphere will logically increase rainfall globally, including on the ocean.

    For de-acidification it is this added fresh water rain that is the true agent of change.

    When pure H2O, contacts carbonic acid H2CO3 the CO2 molecule is broken off and the carbonic acid leaving water again thus raising the pH and liberating a molecule of CO2 from the seawater as it is raining at the surface.

    With luck, the increased rainfall in any one place will indicate increased rainfall eventually everywhere. Putting water in the air by putting air in the water, passively will serve us well.

    We need not worry about covering every square mile of the seas with these machines. They should be concentrated where ocean currents are strongest and we allow the currents to distribute the oxygenated seawater for us when possible.

    My understanding is that well within 30 days after small-scale deployment the first positive effects will be unmistakable.

    It seems simple and easy. May be one wont be able to control where it will rain and how much.
    With rain, global warming will be offsetted to a great extent.

    MattS certainly sounds interesting with all simple ideas.

    Amanda !
    I wish you had given the url of MattS' article.

    In fact his suggestion of growing algae to set the climate change problem also sounds interesting.

    In describing his methodology, his narration is a little suspect as he brings about Omega 3 etc into the picture.
    I wish he had just assumed a low level of production and given the math for how much of green coal is required for the energy requirement.

    How can PBRs solve the problem ? How many are required. What will be the cost ?

    Using PBRs seem unviable.

    I request Matt Snyder to rewrite his views on

    " Commercial Scale Production of Algae Based Drop-In Petroleum Replacements"
