  1. Soil Carbon Sequestration
  1. -001 Study: Seagrass Meadows Can Store Billions of Tons of Carbon (
      "Seagrasses are a vital part of the solution to climate change and, per unit area, seagrass meadows can store up to twice as much carbon as the world's temperate and tropical forests."

      "The research also estimates that, although seagrass meadows occupy less than 0.2 percent of the world's oceans, they are responsible for more than 10 percent of all carbon buried annually in the sea." 06-12

  2. -Exceptional Ecosystem Found Under Arctic Ice (New York Times)
      "The quantities of plankton are 'truly exceptional,' says Walker Smith, a marine biologist at the College of William and Mary in Williamsburg, Va., who was not part of the team conducting the research."

      "If these blooms are widespread under the ice along continental shelves, the primary productivity in these regions could be up to 10 times greater than open-water productivity, the team estimates."

      "In addition, researchers have noted that the Arctic ocean is becoming an enormous sink for atmospheric CO2 as the waters open up in the summer. Yet the open waters in the Chukchi Sea don't show the levels of dissolved CO2 they should if that's the case. Now, it looks as though the answer lies with the under-ice phytoplankton blooms, because they consume the CO2 via photosynthesis, just as land plants do." 06-12

  3. Algae for Carbon Sequestration (
      "The iron feeds algae, which blooms and sucks up damaging carbon dioxide (CO2), then sinks, locking away the harmful greenhouse gas for hundreds of years."

      "As a result of the findings, a ground-breaking experiment will be held this month off the British island of South Georgia, 800 miles south east of the Falklands. It will see if the phenomenon could be harnessed to contain rising carbon emissions." 01-09

  4. Cyanobacteria (
      "Cyanobacteria...also known as blue-green algae, blue-green bacteria, and Cyanophyta) is a phylum of bacteria that obtain their energy through photosynthesis."

      "The ability of cyanobacteria to perform oxygenic photosynthesis is thought to have converted the early reducing atmosphere into an oxidizing one, which dramatically changed the composition of life forms on Earth by stimulating biodiversity and leading to the near-extinction of oxygen-intolerant organisms. According to endosymbiotic theory, chloroplasts in plants and eukaryotic algae have evolved from cyanobacterial ancestors via endosymbiosis." 03-12

  5. Seagrass (
      "These unusual marine flowering plants are called seagrasses because in many species the leaves are long and narrow, and these plants often grow in large 'meadows' which look like grassland: in other words many of the species of seagrasses superficially resemble terrestrial grasses of the family Poaceae."

      "Like all autotrophic plants, seagrasses photosynthesize so are limited to growing in the submerged photic zone, and most occur in shallow and sheltered coastal waters anchored in sand or mud bottoms. Most species undergo submarine pollination and complete their entire life cycle underwater. There are about sixty species worldwide."

      "The most-used methods to protect and restore seagrass meadows include nutrient and pollution reductions, protection using marine protected areas, and restoration using seagrass transplantation."

      Editor's Note: Expanding the world's protected areas along shallow coasts and providing those areas with nutrients and seagrass transplantation may be one of the easier and quicker ways to reverse the amount of CO2 in the air. 06-12

  6. Seagrass Recovery (
      "The success of our innovative techniques have been scientifically evaluated and documented by National Oceanic & Atmospheric Administration (NOAA) and the Florida Fish and Wildlife Conservation Commission. What’s more, because many of our solutions incorporate patented technologies and one-of-a-kind functionalities, Seagrass Recovery is the only place that can offer such a multitude of unique options."

      "Using these methods, and others still under development, Seagrass Recovery is able to re-establish, create and enhance the growth of one of the most productive natural communities in the world."

  7. Study: Iron to Boost Algae for Carbon Sequestration (
      "Combining previous data with new observations and computer simulations, scientists led by Nicolas Cassar of Princeton University show that net community production increases with natural aerosol iron deposition in the Southern Ocean. The results suggest that wind-blown dust -- one of five sources of bioavailable iron to surface waters of the Southern Ocean -- may have important climate implications."

      " 'This iron deposition stimulates the ocean algae to convert carbon dioxide into organic carbon that may sink to ocean depths, potentially influencing the atmospheric carbon dioxide concentration,' according to a statement from Science." 02-09
