            "description": "A project jointly funded by NASA and the National Science Foundation is heading west from Seattle, straight for the twilight zone. Using two research vessels, the Export Processes in the Ocean from Remote Sensing (EXPORTS) oceanographic campaign will study the fates and carbon cycle impacts of microscopic underwater organisms.The large multidisciplinary team, including members from more than 20 different research institutions, is accompanied by advanced underwater robotics and other instruments on a month-long campaign to study the secret lives of tiny organisms called phytoplankton, and the animals that eat them. These organisms can have a large impact on Earth's carbon cycle, storing carbon dioxide in a part of the ocean known as the twilight zone, between 650 and 3300 feet below the surface. || ",

            "title": "Simulated Atmospheric Carbon Concentrations",
            "description": "Carbon exists in many forms—e.g., carbon dioxide (CO2), carbon monoxide (CO)—and continually cycles through Earth’s atmosphere, ocean, and terrestrial ecosystems. This visualization, created using data from the 7-km GEOS-5 Nature Run model, shows average column concentrations of atmospheric CO2 (colored shades) and CO (white shades underneath) from January 1, 2006 to December 31, 2006.CO2 variations are largely controlled by fossil fuel emissions and seasonal fluxes of carbon between the atmosphere and land biosphere. For example, dark red and pink shades represent regions where CO2 concentrations are enhanced by carbon sources, mainly from human activities. During Northern Hemisphere spring and summer months, plants absorb a substantial amount of CO2 through photosynthesis, thus removing CO2 from the atmosphere. Atmospheric CO, a pollutant harmful to human health, is produced mainly from fossil fuel combustion and biomass burning. Here, high concentrations of CO (white) are mainly from fire activity in Africa, South America, and Australia. Scientists use model output data such as these to help answer important questions about Earth’s climate and to help design future satellite missions.These model simulations use fossil fuel emissions estimates provided by the Emissions Database for Global Atmospheric Research (EDGAR). NASA’s Quick Fire Emissions Dataset (QFED) estimates fire emissions using MODIS fire radiative power observations. Additional, observationally constrained estimates of CO2 flux between the atmosphere and land and ocean carbon reservoirs were produced as part of NASA’s Carbon Monitoring System Flux Pilot Project (http://carbon.nasa.gov/cgi-bin/cms/inv_pgp.pl?pgid=581). Land biosphere fluxes come from the Carnegie-Ames-Stanford Approach Global Fire Emissions Database (CASA-GFED) model which incorporates MODIS vegetation classification and AVHRR Normalized Difference Vegetation Index (NDVI) data. Ocean fluxes are produced by the NASA Ocean Biogeochemical Model (NOBM) which incorporates MODIS chlorophyll observations. || ",

            "description": "The past decade is the warmest on record since instrumental measurements began in the 1880s. Previous research suggested that in the '80s and '90s, warmer global temperatures and higher levels of precipitation — factors associated with climate change — were generally good for plant productivity. An updated analysis published this week in Science indicates that as temperatures have continued to rise, the benefits to plants are now overwhelmed by longer and more frequent droughts. High-resolution data from the Moderate Resolution Imaging Spectroradiometer, or MODIS, indicate a net decrease in NPP from 2000-2009, as compared to the previous two decades. || ",

            "title": "Correlation Between Tropospheric Carbon Dioxide Concentration and Seasonal Variation of the Biosphere",
            "description": "This animation shows the correspondence between the drawdown of tropospheric carbon dioxide in the earth's atmosphere, and the seasonal variation of the biosphere of the earth. The pattern of white squares indicates regions where the concentration of tropospheric CO2 is higher than the trend, while regions devoid of the squares are areas where the CO2 concentrations are lower than the trend. The trend was calculated by a least-squares line fit to a moving 8-day global average of CO2 concentration provided by the AIRS instrument on the Aqua satellite, and increases over the course of the animation (Sept. 2002-Sept. 2006) from 374 ppm to 383 ppm. The biosphere data is provided by the SeaWiFS instrument aboard the SeaStar satellite.During spring and summer months, the consumption of CO2 through plant respiration increases, reducing the concentration of CO2 (the white squares) over the more productive areas. In the animation, this is seen as a tendency for the CO2 concentration to drop below the trend over areas of deeper green. The cycle is especially apparent in the Northern Hemisphere. || ",

            "title": "The Carbon Cycle",
            "description": "Carbon is the basic building block of life, and these unique atoms are found everywhere on Earth. Carbon makes up Earth's plants and animals, and is also stored in the ocean, the atmosphere, and the crust of the planet. A carbon atom could spend millions of years moving through Earth in a complex cycle. This conceptual animation provides an illustration of the various parts of the Carbon cycle. Purple arrows indicate the uptake of Carbon; yellow arrows indicate the release of Carbon. On land, plants remove carbon from the atmosphere through photosynthesis. Animals eat plants and either breath out the carbon, or it moves up the food chain. When plants and animals die and decay, they transfer carbon back to the soil. Moving offshore, the ocean takes up carbon through physical and biological processes. At the ocean's surface, carbon dioxide from the atmosphere dissolves into the water. Tiny marine plants called phytoplankton use this carbon dioxide for photosynthesis. Phytoplankton are the base of the marine food web. After animals eat the plants, they breathe out the carbon or pass it up the food chain. Sometimes phytoplankton die, decompose, and are recycled in the surface waters. Phytoplankton can also sink to the bottom of the ocean, where they become buried in marine sediment. Over long time scales, this process has made the ocean floor the largest reservoir of carbon on the planet. In a process called upwelling, currents bring cold water containing carbon up to the surface. As the water warms, the carbon is then be released as a gas back into the atmosphere, continuing the carbon cycle.  Carbon is found in the atmosphere as Carbon dioxide, which is a greenhouse gas. Greenhouse gases act like a blanket, and trap heat in the atmosphere. In the past two centuries, humans have increased atmospheric carbon dioxide by more than 30%, by burning fossil-fuels and cutting down forests. || ",

            "description": "The Carbon  Cycle - The carbon cycle on land, acted out here show a tree  taking in carbon dioxide from the atmosphere, and combined with water  and nutrients from the soil, growing. In the fall and winter, parts  of the growth die off and release some carbon back into the system.  At some point, the tree is no longer able to take in carbon and  begins to die. When that happens, all the carbon absorbed in its body  is released back into the cycle as it decomposes. Fire can accelerate  this, sending plumes of carbon-laden aerosols into the atmosphere, as  well as leaving carbon-rich ash deposits on the ground for further  decomposition and recycling. || ",

            "description": "Carbon And The Ocean — The Slow Cycle - The oceans are vast, and their processes as complex as their waters are deep.Phytoplankton absorbs carbon dioxide from the atmosphere and nutrient rich waters and grows in wide colonies called blooms. These blooms are highly dependent on surrounding environmental conditions.As phytoplankton grows, it forms the foundation for the food chain, thus passing carbon up to higher life forms. But just as on land, links in the ocean's chain of life also break, and stored carbon settles out of the top layers of water. A portion of it gets swept back to the surface as upwellings, only to begin again, but a major portion sinks to the bottom, becoming what oceanographers call 'marine snow.' This decomposing biological matter literally precipitates through the water and builds up on the ocean bottom, essentially sequestered from the rest of the Earth for geologically long periods of time. || ",
