In the Southern Ocean, large quantities of  phyto-plankton are able to significantly reduce the carbon dioxide content of the surface waters.
ScienceDaily (Feb. 14, 2008)

This plankton growth can affect the global carbon dioxide cycle and is one of the results from an Antarctic expedition which has just drawn to a close in Cape Town on February 4, and which was led by the Alfred Wegener Institute the research vessel Polarstern.

The recently concluded Polarstern expedition was devoted primarily to organisms and materials cycles in the ocean. Under the leadership of Prof Dr Ulrich Bathmann of the Alfred Wegener Institute, 53 Scientists from nine countries have been studying the biological carbon pump in the Southern Ocean, among other topics. Algal plankton absorbs carbon through photosynthetic activity, hence removing carbon dioxide from the atmosphere. Algal plankton growing in this pool started to decay and to sink to the seafloor.

The scientists investigated an algal carpet drifting in the water near the edge of the sea ice. This algal bloom measured 700,000 square kilometres, i.e. approximately twice the size of Germany. The researchers wanted to find out which physical conditions lead to such algal blooms, and how they affect the living and non-living environment. Their measurements demonstrate a significant decrease in the carbon dioxide content of the surface water.  read more...



Ocean Life Under Threat From Climate Change


ScienceDaily (June 11, 2008) — “Marine ecosystems are undoubtedly under-resourced, overlooked and under threat and our collective knowledge of impacts on marine life is a mere drop in the ocean,” wrote Dr Anthony Richardson, from The University of Queensland and CSIRO, and his co-author, Dr Elvira Poloczanska from CSIRO in Hobart.

“There is an overwhelming bias toward land-surface studies which arise in part because investigating the ocean realm is generally difficult, resource-intensive and expensive,” they said.

The disparity in focus on land-based compared to marine impacts was highlighted in the Intergovernmental Panel on Climate Change’s (IPCC’s) Fourth Assessment Report (2007), which included 28,500 significant biological changes in terrestrial systems but only 85 in marine systems. read more





Rising CO2 Destroys  Grasslands

Rising carbon dioxide levels could cause significant changes to open grazing lands and rangelands around the world, reports a study published in the journal Proceedings of the National Academy of Sciences (PNAS).

Using an experimental field station in the Colorado short grass steppe to determine the effects of CO2 on plant species composition, researchers led by Jack Morgan of the United States Department of Agriculture found that elevated carbon dioxide levels drive an increase in small woody shrubs in grass-dominated open rangelands. The results suggest that "CO2 is contributing to the replacement of grasslands with shrub lands unsuitable for forage, bringing with it biological and economic impacts," according to PNAS.

Can Carbon Dioxide Be A Good Thing? Physicist Explains Benefits Of Carbon Dioxide

June 1, 2007 — A physicist from Colorado State University and his colleagues from the North American Carbon Program (NACP) have discerned and confirmed the unforeseen advantages of rising carbon dioxide levels. Through the processes of photosynthesis and respiration, scientists have been able to elucidate why plants are growing more rapidly than they are dying. The NACP is employing methods, such as the use of cell phone and aircraft towers to monitor and retrieve carbon data for their continuing study.

Too much carbon dioxide can be a bad thing, but sometimes it can have a positive effect on plants and trees. The more carbon emissions we dump into the air, the faster forests and plants grow.  read more...





Higher River Levels Predicted As More Carbon Dioxide Makes Plants Less Thirsty

ScienceDaily (Sep. 11, 2007) — Rising carbon dioxide levels will increase river levels in the future, according to a team of scientists from the Met Office Hadley Centre, the University of Exeter and the Centre for Ecology & Hydrology

The findings, published on 30 August 2007 in the journal Nature, suggest that increasing carbon dioxide will cause plants to extract less water from the soil, leaving more water to drain into rivers which will add to the river flow increases already expected due to climate change.

Last year, members of the research team showed that this effect can already be seen in historical river flow records.

This new study shows that the effect of plant responses to carbon dioxide could be as important as those of increased rainfall due to man-made climate change. read more...






NASA Launches Ocean Satellite To Keep A Weather, Climate Eye Open

ScienceDaily (June 23, 2008) — A new NASA-French space agency oceanography satellite launched June 20 from Vandenberg Air Force Base, Calif., on a globe-circling voyage to continue charting sea level, a vital indicator of global climate change. The mission will return a vast amount of new data that will improve weather, climate and ocean forecasts.

With a thunderous roar and fiery glow, the Ocean Surface Topography Mission/Jason 2 satellite arced through the blackness of an early central coastal California morning at 12:46 a.m. PDT, climbing into space atop a Delta II rocket. Fifty-five minutes later, OSTM/Jason 2 separated from the rocket's second stage, and then unfurled its twin sets of solar arrays. Ground controllers successfully acquired the spacecraft's signals. Initial telemetry reports show it to be in excellent health.

"Sea-level measurements from space have come of age," said Michael Freilich, director of the Earth Science Division in NASA's Science Mission Directorate, Washington. "Precision measurements from this mission will improve our knowledge of global and regional sea-level changes and enable more accurate weather, ocean and climate forecasts." read more...

The Science of ocean Ecorestoration

Planktos projects restore plankton populations to revive marine ecosystems, while at the same time removing carbon dioxide from the atmosphere. Carbon dioxide is the main "greenhouse gas" (GHG) contributing to global climate change. Like trees on land, ocean phytoplankton use photosynthesis to turn carbon dioxide into oxygen and plant biomass. Phytoplankton process more than half of the world's atmospheric CO2 and thus produce most of the world’s oxygen. This same phyto-plankton also feeds the marine food web, feeding all ocean creatures such as krill, anchovies & herring, menhaden, tuna, salmon,  cod, marine mammals, and sea birds.

Plankton populations have been observed to be collapsing worldwide in the past 30 years, according to pivotal work sponsored by NASA and NOAA. This decline closely correlates with a decline in iron-rich dust reaching the oceans, the critical ingredient in ocean photosynthesis. A greening of dry grasslands, especially in Asia, has reduced the availability of iron-rich dust normally picked up from arid lands and deposited by wind events onto the ocean surface thousands of kilometers away. This has coincided with rapidly declining plankton populations. And of course as the ocean plants disappear less CO2 is removed from the atmosphere/ocean and less food is made available to marine food webs.

Life-giving dust from N. Africa swirls over the Atlantic

Many open ocean ecosystems depend on dust clouds originating from land to bring vital micronutrients. Each year 500 million tonnes of dust from Africa lands in the North Atlantic ocean sustaining the ocean forest. Globally it is estimated that 900 million tonnes of dust blows in the wind each year.

In spite of the many reports of desertification, and the real crisis it is, in the most arid parts of the world desertification is not winning against CO2 greening. The dust the oceans depend upon for their productivity is dramatically reduced as shown below. The most likely culprit for the cause of this missing dust in the wind is CO2 stimulated plant growth creating increasing ground cover.  Report clearly show that the traditional sources of long range aeolian dust is dramatically reduced. This fact becomes obvious when one considers that during the 1930's in North America, the period known as the dust bowl days, saw hundreds of millions of tonnes of precious topsoil blowing in the wind in the American Mid-West. The crisis was so great that the US Soil Conservation Service was created by Congress and it's historic success is chronicled in history.

The scientists of the Soil Conservation service reasoned that it was improper agricultural methods that were causing the topsoil to blow away. The solution they provided was simple: change the grain crops grown from summer to winter wheat. Winter wheat, also called spring wheat, was to be planted in the fall after the first rains arrived. The wheat would germinate and then go dormant over the winter months. As spring arrived with plenty of water accumulated from the winter precipitation available the wheat would grow and produce a bumper crop to be harvested in the spring. Instead of plowing the ground at the beginning of summer, the remains of the stubble were to be left on the ground as "ground cover" protecting the soil from being blown away. In a few short years a new crop and method stopped the loss of topsoil and the great dust storms ended.

While this "modern" agricultural method became commonplace in the 1930's in North America it was not adopted in other parts of the world until 20 years later. In the 1950's China's growing population needed wheat and introduced topsoil sparing methods on much of their vast dusty grasslands. An enormous area came under this ecolocigally sensitive agriculture within the effect of greatly reducing aeolian dust. For China this was a good thing but it was another nearly 50 years before science realized that the Chinese dust had been a major source of nutrients for the oceans of the Northern Hemisphere.

Global Dust 'Sunscreen' Has Likely Thinned, Report NASA Scientists  2007

A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases – sunlight blocked by dust, pollution and other aerosol particles – appears to have lost ground.

Planktos Science is engaged in development scale test restorations of selected regions of declining ocean regions. In these research projects we will restore plankton blooms by adding natural iron micro-nutrients, mineral dust, to the surface ocean in infinitesimal amounts. Where natural iron levels in the ocean are normally 3 parts per trillion we will raise the iron concentration to 50-100 parts per trillion.  Equatorial regions are often perfect locations for managed plankton blooms, owing to their warm water temperatures, high nutrient availability, and low iron concentrations. Planktos’ stimulated plankton blooms mimic natural processes and are roughly one percent the size of naturally occurring blooms. Each tonne of iron dust added can generate a plankton bloom that replenishes the food chain for months at a time and can sequester thousands of tonnes of carbon dioxide.

Greenhouse gas sequestration includes the removal of atmospheric carbon dioxide and the subsequent storage of carbon in plant and animal material for decades or longer. In a managed bloom, carbon sequestration occurs when dead plankton and other organic waste material sink to the deep ocean as “marine snow". The duration for which the carbon is sequestered is measured by the depth it reaches. Carbon that sinks below 200m will be sequestered for decades, carbon that sinks below 500m will be sequestered for centuries, and carbon that sinks below 1000m will be sequestered for millennia.

To date, there have been ten major iron-enrichment experiments conducted around the world. These experiments have studied the effects of iron dust on plankton growth and have confirmed the concept and ecological success of iron-enriched plankton blooms. Planktos uses this scientific foundation as the base of its project design. Building on these previous iron-enrichment experiments and well-known plankton ecology and ocean carbon cycle sciences, Planktos will quantify the amount of CO2 removed from the atmosphere, the amount of carbon sequestered to the deep ocean, and the depth to which the carbon is sequestered (and thus the length of time). Planktos will also be the first institution to study an iron-stimulated plankton bloom for its entire life cycle. The company intends to share in a transparent fashion a great deal of new data supporting the fields of oceanography, marine biology, and the value of in tact ocean ecosystem services. 

 Ocean Iron Research Trials

Planktos uses strict scientific protocols and overlapping sampling techniques to measure the effects of iron dust on plankton productivity, the amount of carbon sequestered, and the benefits of restored plankton communities on marine ecosystems. Some examples of equipment Planktos will make use of are: ship-borne sampling, CTD and rosette, towed body, tracking buoys, aerial and satellite telemetry. Some examples of data Planktos will collect are: physical & chemical properties of ocean water, nutrient concentrations inside and outside of the bloom, and quantitative measurements of plankton productivity. All measurements will be made before, during, and after the iron-enrichment project.

Where Might We Find A Means To Restore Natures Balance
RAIN AND DUST, The answer my friend is blowing in the wind.

This dust in the wind arrives only episodically though in some regions it can be both predictable and substantial. This gigantic dust storm blows off the Sahara enshrouding the Canary Islands. In a few days it left a gritty layer on car windshields in Florida. Each year hundreds of millions of tonnes of this mineral rich dust blows onto the Atlantic Ocean.


Ocean Acidification

Ocean Acidification is an inevitable result of the most basic chemical processes. Water and CO2 are readily mixed and when they do the reaction H2O+CO2 «» H2CO3 (carbonic acid) happens. The controlling influences on this reaction are time, concentration of CO2, and temperature. In the global perspective there is infinite time and infinite water so what remains to control the reaction is the concentration of CO2. Prior to the emergence of the fossil fuel age of human society CO2 was relatively constant over the course of millions of years at levels of  under 300 ppm. Today we have levels that are approaching 400ppm, as a high altitude global average. At sea level in many regions where the CO2 enters the ocean the levels are much much higher.

Let's look at the system before man and the fossil fuel age came on the scene. The ocean’s last big splurge on CO2-fueled acidification was 55 million years ago. That catastrophe caused by volcanic eruptions and possibly by disturbance of vast undersea gas deposits triggered a mass extinction of marine organisms. It took the oceans over 100,000 years to recover.

Today the ocean is becoming chemically hostile to many of its inhabitants especially in colder seas like Alaska and the Pacific Northwest and also the vast Southern Ocean. 

In 2005, Victoria Fabry, a biologist at California State University San Marcos, showed that seawater from the Gulf of Alaska had become acidic enough to dissolve the shells of tiny creatures called pteropods a major food source for salmon, cod, pollock, herring, and many other species. Other scientists amassed 77,000 measurements at sea and proved just how rapidly fossil fuel emissions are acidifying the ocean.

Every day, 22 million tons of CO2 sea, reacting with seawater to produce carbonic acid. The oceans soak up enough CO2 every five days to outweigh the entire year’s catch of wild fish for the entire planet. Fossil fuel emissions make up 90 percent of this acidifying flux.

Below 100 meters, the ocean off Alaska is now so acidic and so depleted of calcium carbonate that some shellfish and zooplankton species dissolve while they’re alive. Off the Pacific Northwest coast, the same deadly conditions prevail below 200 meters. And throughout the Pacific, this acidic “horizon” is now rising at a rate of one meter per year.

If CO2 emissions continue their unregulated increase conservative predictions have these acidic conditions filling the North Pacific all the way to the surface by 2050. The pace of acidification is accelerating with emissions. By the end of this century, it will have increased 150 percent, and with it acidification’s insidious effects. As the acidification worsens it depletes the rich soup of calcium carbonate in seawater a key nutrient at the foundation of the food web. Most calcifying organisms corals, zoo plankton, clams, urchins, even king crabs rely on this calcium soup for raw material to build and repair themselves. As acidification steals their calcium supply, these organisms literally start dissolving. Many die outright. Survivors weaken. The swimming and scuttling shelled creatures lose their knack for hunting evading predators, and reproducing. Add enough CO2 to the water and all sea life begins to go into CO2 shock, the same effect that you or I experience if we rapidly hyperventiate into a paper bag, we simply lose consciousness and stop breathing.
