These carbon and greenhouse gas variables were examined for major terrestrial ecosystems (forests, grasslands/shrublands, agricultural lands, and wetlands) and aquatic ecosystems (rivers, streams, lakes, estuaries, and coastal waters) in the Eastern United States in two time periods: baseline (from 2001 through 2005) and future (projections from the end of the baseline through 2050). The Great Lakes were not included in this assessment due to a lack of input data.
The assessment was based on measured and observed data collected by the U.S. Geological Survey and many other agencies and organizations and used remote sensing, statistical methods, and simulation models.
Rivers move large amounts of carbon downstream to the oceans. Developing a better understanding of the factors that control the transport of carbon in rivers is an important component of global carbon cycling research. The study is a product of the USGS John Wesley Powell Center for Analysis and Synthesisand the USGS Land Carbon program.
Different downstream patterns were found between the two river systems. The amount of carbon steadily increased down the Missouri River from headwaters to its confluence with the Mississippi River, but decreased in the lower Colorado River. The differences were attributed to less precipitation, greater evaporation, and the diversion of water for human activities on the Colorado River. For upstream/headwater sites on both rivers, carbon fluxes varied along with seasonal precipitation and temperature changes.
The study presents estimates of changes in the amount of carbon moving down the Colorado and Missouri Rivers and provides new insights into aquatic carbon cycling in arid and semi-arid regions of the central and western U.S, where freshwater carbon cycling studies have been less common. This work is part of an ongoing effort to directly address the importance of freshwater ecosystems in the context of the broader carbon cycle. In the future, changing hydrology and warming temperatures will increase the importance of reservoirs in carbon cycling, and may lead to an increase in Greenhouse Gas Emissions that contribute to global warming, but may also increase the amount of carbon buried in sediments.

The project aims to resolve disagreements between the computer models, and actual forest CO2 measurements by developing new knowledge and deeper understanding of seasonal climate, photosynthesis, and water relationships in Amazon tropical forests, through the use of advanced remote-sensing techniques and field observations.
The project focuses on existing tropical forest study sites near Manaus and Santarem, Brazil. Scientists will measure physiological properties of leaves and trees, and water flow, and use innovative remote-sensing instruments to monitor the light-reflecting properties of the forest and the effects of clouds and smoke on solar radiation. Scientists will also model the three-dimensional variation in photosynthesis in various forest structures and light levels.

Widespread lake shrinkage in discontinuous regions of permafrost has been linked to global warming, climate change and shallow permafrost thaw. Counter-intuitively, USGS scientists have observed newly forming permafrost around Twelvemile Lake in interior Alaska, where lake water level has dropped by several meters over the past three decades.
Permafrost typically forms in colder climates when average annual temperatures remain close to or below freezing. Permafrost soils accumulate ice and plant material and can impede groundwater flow. During periods of thaw, water, methane and other gases are released from their frozen pockets of ice.
By understanding permafrost thaw, its degradation in a warming climate, and its impacts on ecosystems and society, managers will be able to plan for rising global temperatures, and climate change. New permafrost formation should also be considered as a possibility in some systems.
This study considered ecological succession, the pattern of vegetation regrowth, within the receded lake margin as the driver of new permafrost through alterations in ground shading and water infiltration. This hypothesis was tested by modeling variably saturated groundwater flow and heat transport under freeze-thaw conditions.
The simulations supported new permafrost development under current climatic conditions, when the net changes effects of woody vegetation are considered, thus pointing to the role of ecological succession.

In response to the DoI's Powering Our Future initiative, the U.S. Geological Survey (USGS) has begun investigating how to assess the impacts of wind energy development on wildlife at a national scale. In additional to the turbines and blades, habitat impacts include the turbine pads, service roads, transmission lines, substations, meteorological towers, and other structures associated with wind energy siting, generation, and transmission. Knowing the location of individual turbines, as well as information such as the make, model, height, area of the turbine blades, and capacity creates new opportunities for research, and important information for land and resource management. For example, turbine-level data will improve scientists' ability to study wildlife collisions, the wakes causes by wind turbines, the interaction between wind turbines and ground based radar, and how wind energy facilities overlap with migratory flyways.
In addition to the value this powerful tool has to Federal and State land managers, non-governmental organizations, the energy industry, scientists, and the public, it will be a useful component in the methodology that the USGS is developing for assessing wind energy impacts. Once developed, the methodology will be externally peer-reviewed and tested with pilot-level data projects. Once peer reviewed, the revised methodology will be published for others to understand and use.
During periods of thaw, soil, rocks, small plants, and gases -- CO2, nitrogen and methane -- are released from the permafrost into the atmosphere. In the next 50 years, as arctic systems warm, the release of carbon and nitrogen in permafrost could greatly exacerbate the warming phenomenon, according to USGS scientists and their collaborators.
The U.S. Geological Survey (USGS) contributes to several science networks dedicated to detecting and understanding permafrost, its degradation in a warming climate, and its impacts on ecosystems and society. Time series of observations are the focus of several networks such as the Real-Time Permafrost and Climate Monitoring Network in Arctic Alaska, Circumpolar Active Layer Monitoring (CALM), borehole temperature monitoring, and ecosystem assessments. Meanwhile, spatial surveys are used to develop an understanding of complex processes involved in permafrost formation and degradation, and permafrost cores are used to understand the timing of permafrost formation and degradation on longer timescales. Ultimately and in tandem with computer modeling, the measurements of ice, water, carbon, and biology fundamentally improve our assessments of arctic change.
Permafrost is primarily found where average annual air temperatures remain below freezing: Scandinavia, Siberia, Tibet, Alaska, and Canada as well as in Patagonia in Chile and the Southern Alps in New Zealand.
Periods of warming in the Arctic cause permafrost to degrade. As permafrost thaws, large amounts of carbon and nitrogen are subjected to decomposer organisms in the warming soil. Potentially huge amounts of carbon dioxide and methane are released into the atmosphere, and these gases in turn exacerbate the warming climate because of their greenhouse effect in the upper atmosphere.
The USGS uses carbon comparisons between past climate cycles and recent warming trends; between wildfires and unburned landscapes; between wetter and drier conditions; and younger to older thaw histories,
to help build a picture of how ecosystems and the atmosphere are likely to respond in a permafrost-free future. (Source: U.S. Geological Survey, 13 Jan., 2014) Contact: U.S. Geological Survey, www.usgs.gov

HNG production involves pulsing a range of low energy frequencies in a very specific sequence into water. The pulsing treatment effectively manipulates the molecules to line up in a certain structure which are then put through a splitting process. The result is HNG which instantly neutralizes carbon fuel pollution emissions. HNG can be pressurized up to 2 bars and combusts at a rate of 9000 meters per second while normal Hydrogen combusts at a rate 600 meters per second. Oxygen values actually increase when HNG is inserted into a diesel flame and HNG acts like a vortex on fossil fuel emissions causing the flame to be pulled into the centre thus concentrating the heat and combustion properties.
Injecting HNG into a combustion chamber produces several effects that increase the burn efficiency of the fuels. HNG gasification effectively burns unburned residue/cluster while completing the burn process quicker. The long term impact of using HNG in the burning of fossil fuels can provide the balanced solution for the on going economic-climate change debate.

The USGS approach is geologically based, as the rock layers included in the assessment were limited to those determined to have sufficient natural seals to prevent CO2 from escaping.
The USGS released its first national assessment of technically accessible geologic CO2 storage potential in June of 2013. According to that assessment, the U.S. has the potential to store a mean of 3,000 metric gigatons of CO2 in geologic basins throughout the country. This national assessment complements the regional estimates that the Department of Energy includes in their periodically updated Atlas.

Unfortunately there are a couple of problems. Firstly, submitting data for the project is voluntary. As the CSI points out in its press release the data set comprises 55 percent of cement production outside of China. A rough calculation based on global cement production capacity suggests that this could only account for about one third of cement made. So how much carbon does the other two-thirds of cement made emit?
Secondly, although CO2 emissions per tonne of cement have gone down by a sixth since 1990, global cement production more than tripled in the same time period. USGS data placed world production at 1.40Bt in 1990. It estimated 3.59Bt in 2011. In terms of net CO2 released into the atmosphere, in 1990 this was 1058Bt. In 2011 it was 2260Bt.
The CSI data shows that the cement industry has made an effort to reduce CO2 emissions since 1990, but this has been counteracted by a rise in cement production. To compensate for the rise in production between 1990 and 2011 the specific net CO2 emissions-per-tonne of cementitious product would have had to have fallen to below 300kg/t, a drop of 60 percent.
As the CSI has demonstrated, emissions and production are gradually separating in the cement industry. From 2010 to 2011 specific net CO2 emissions per tonne of cementitious product fell from 638kg/t to 629kg/t. If this trend continues -- and if it is representative for the cement producers the CSI doesn't cover -- then the industry may be getting a handle on its emissions. We may be about to hit peak emissions for the cement industry sooner rather than later. (Source: Global Cement, July 17, 2013)

Based on present-day geologic and hydrologic knowledge of the subsurface and current engineering practices, this assessment looked at the potential for CO2 storage in 36 basins in the U.S.. The largest potential is in the Coastal Plains region, which accounts for 2,000 metric gigatons, or 65 percent, of the storage potential. Alaska and the Rocky Mountains and Northern Great Plains region also have significant storage capacity. Technically accessible storage resources are those that can be accessed using today's technology and pressurization and injection techniques. The most common method of geologic carbon storage involves pressurizing CO2 gas into a liquid, and then injecting it into subsurface rock layers for long-term storage.
The assessment is the first geologically based and probabilistic assessment, estimating a range of 2,400 to 3,700 metric gigatons of CO2 storage potential across the U.S . For comparison, the U.S. Energy Information Administration (EIA) estimates that in 2011, the U.S. emitted 5.5 metric gigatons of energy-related CO2, while the global emissions of energy-related CO2 totaled 31.6 metric gigatons. Metric gigatons are a billion metric tons.
Although the scope of sequestration included in this assessment is unprecedented, injecting CO2 into geologic formations is not a new process or technology. CO2 injection has been one method of enhanced oil recovery since the 1980s. The process works by flooding the oil reservoir with liquid CO2, which reduces the viscosity of the hydrocarbons and allows them to flow to the well more easily.
The USGS project results announced today represent an assessments of storage capacity on a regional and national basis, and results are not intended for use in the evaluation of specific sites for potential CO2 storage. All sedimentary basins in the U.S. were evaluated, but 36 were assessed because existing geologic conditions or the available data suggested only these 36 met the assessment's minimum criteria.
In 2007, Congress authorized the USGS to conduct the carbon sequestration assessment in the Energy Independence and Security Act of 2007. The USGS also studies biologic carbon sequestration -- sequestration that happens naturally in trees, fields, and different types of ecosystems that store carbon. The USGS has already completed assessments for the Great Plains Region and the western U.S.; reports on the eastern U.S., Alaska and Hawaii will follow.

A team led by research oceanographer Curt Storlazzi of the USGS Pacific Coastal and Marine Science Center in Santa Cruz, Calif., compared passive "bathtub" inundation models with dynamic models for two of the Northwestern Hawaiian Islands in the Papahanaumokuakea Marine National Monument. The team studied Midway, a classic atoll with islands on the shallow atoll rim and a deep, central lagoon, and Laysan, which is higher, with a deeper rim and an island in the center of the atoll. Together, the two locations exhibit landforms and coastal features common to many Pacific islands. Managed by the U.S. Fish and Wildlife Service, they are also among the world's most important nesting and breeding sites for migratory birds and other wildlife.
The team found that at least twice as much land is forecast to be inundated on Midway and Laysan by sea-level rise than was projected by passive models. For example, 91 percent of Midway's Eastern Island is projected to be inundated under a model that takes into account storm and wave activity accompanied by a sea-level rise of 2 meters as compared with only 19 percent under passive sea-level-rise models. Storm waves on Midway are also projected to be three to four times higher than they are today, because more deep-water wave energy could propagate over the atoll rim and larger wind-driven waves could develop on the atoll. These findings have importance not only for island wildlife on the largely uninhabited Northwestern Hawaiian Islands and other low-lying Pacific Island groups.

To generate their estimates, the USGS scientists studied how permafrost-affected soils, known as Gelisols, thaw under various climate scenarios. They found that all Gelisols are not alike: some have soil materials with large amounts of decaying organic matter that burns easily and will impart newly thawed nitrogen into the ecosystem and atmosphere. Others have materials that are very nutrient rich and will impart a lot of nitrogen into the ecosystem. All Gelisols will contribute carbon dioxide and likely some methane into the atmosphere as a result of decomposition once the permafrost thaws. And, gases will themselves contribute to further warming.
"The scientific community researching this phenomena has made these international data available for the upcoming Intergovernmental Panel on Climate Change says USGS soil scientist Jennifer Harden. "As permafrost receives more attention, we are sharing our data and our insights to guide those models as they portray how the land, atmosphere, and ocean interact." Harden added.

The research forecasts that under faster sea-level rise rates, salt marshes could bury up to four times as much carbon as they do now. The study forecasts that marshes will absorb some of that carbon dioxide, and if other coastal ecosystems -- such as seagrasses and mangroves -- respond similarly, there might be a little less warming.
Interestingly, salt marshes are perhaps the best example of an ecosystem that actually depends on carbon accumulation to survive climate change: the accumulation of roots in the soil builds their elevation, keeping the plants above the water. Salt marshes store significant quantities of carbon by taking carbon dioxide out of the atmosphere through their leaves, and then storing it in their roots. As plants die, the carbon becomes part of the soil and helps the marsh survive sea level rise.
"Coastal wetlands are among the most economically and ecologically valuable ecosystems on Earth, with their services estimated worth about $15,000 an acre," said Matthew Larsen, associate director for climate and land use research at the U.S. Geological Survey. "They provide clean water, abundant food, wildlife habitat and protection from storms. This and other USGS research aims to understand and forecast the vulnerability of coastal wetland systems to global change and identify ways that managers can effectively respond to global change effects."
Kirwan cautioned that the study also showed that marshes can survive only moderately fast rates of sea level rise. To survive, the elevation of the soil surface has to build vertically through time. If the seas rise more quickly than the marsh can build up, marshes drown and die off. "At fast levels of sea level rise, no realistic amount of carbon accumulation will help them survive. And, , if marshes are drowned by fast-rising seas, they no longer would provide a significant carbon storage capacity," Kirwan said.
The US DOI manages 35 million acres of low-lying coastal areas, including marshes and thousands of miles of shoreline. The U.S. Fish and Wildlife Service alone manages about 5 million acres of coastal wetlands.
"This research can help decision makers understand and prepare for how coastal areas may fare in response to climate change," said Glenn Guntenspergen, a USGS researcher who leads a project on Coastal Marsh Response to Climate and Land Use Change Project that this study was a part of. Kirwan and his co-author, Simon Mudd, a geosciences researcher at the University of Edinburgh used computer models to predict salt marsh growth rates under different climate change and sea level scenarios.

Over the past two years, crews drilled nine wells in Utah's Black Rock Desert basin south of Delta to test out a theory that water at high temperatures might exist deep beneath the surface that would be hot enough to be turned into steam, which could then be used to generate electricity.
The agency has identified an approximately 100-square-mile area within the Black Rock Desert basin it believes could eventually support power plants that could conservatively produce hundreds of megawatts of electricity. The area is especially attractive for geothermal development because of the existing infrastructure, including a large coal-fired power plant, a 300-MW wind farm and a nearby major electrical transmission line.
The U.S. Geological Survey several years ago conducted a survey of the nation's available geothermal resources and, at that time, estimated 80 percent of the potential sites had yet to be discovered.

"Ocean acidification is a particularly vexing problem associated with the release of CO2 into the atmosphere from the burning of fossil fuels because it interferes with the ability of marine organisms to build hard shells of calcium carbonate," said USGS Director Marcia McNutt. "Comparatively more research has been devoted to the tropics, where coral reefs are threatened. This important expedition focuses on polar latitudes, where the acidification effects can cascade from microscopic organisms up to our economy, as the organisms at risk form the base of the food chain for some of the world's most productive fisheries."
Oceans currently absorb about one-fourth of the greenhouse gas from the atmosphere. Ocean acidification occurs when carbon dioxide (CO2) increases in the atmosphere and is absorbed by the ocean. Ocean acidity will continue to rise as CO2 levels are projected to increase. The Arctic Ocean's cold surface waters absorb CO2 more rapidly than warmer oceans, thus contributing to its vulnerability. This vulnerability is increased as the warming climate causes sea-ice to retreat and melt, leaving less of a buffer and more exposure of surface water to the atmosphere.
On the previous two cruises in 2010 and 2011, scientists collected more than 30,000 water samples and traveled throughout the Canada Basin up to very near the North Pole. Data from the cruises are currently being processed. "This cruise offers us an opportunity to collect more information over a vast spatial extent of the Arctic Ocean," said USGS oceanographer and project chief Lisa Robbins. "These data will provide a better understanding of the current patterns of acidification and thus they will significantly contribute to society's efforts to understand, forecast, and potentially mitigate impacts to the Arctic ecosystem and its many globally important resources."
USGS field experiments on ocean acidification are currently being run in tropical, temperate, and polar environments, including the Gulf of Mexico, Florida Keys, Virgin Islands, and the Arctic Ocean.

Since about 1990, sea-level rise in the 600-mile stretch of coastal zone from Cape Hatteras, N.C. to north of Boston, Mass. -- coined a "hot spot" by scientists -- has increased 2 - 3.7 millimeters per year; the global increase over the same period was 0.6 to 1.0 millimeter per year. The report shows that the sea-level rise hotspot is consistent with the slowing of Atlantic Ocean circulation. Models show this change in circulation may be tied to changes in water temperature, salinity and density in the sub-polar north Atlantic. Though global sea level has been projected to rise roughly two-to-three feet or more by the end of the 21st century, it will not climb at the same rate at every location. Differences in land movements, strength of ocean currents, water temperatures, and salinity can cause regional and local highs and lows in sea level.
"Cities in the hot spot, like Norfolk, New York, and Boston already experience damaging floods during relatively low intensity storms," said Dr. Asbury Sallenger, USGS oceanographer and project lead. "Ongoing accelerated sea level rise in the hotspot will make coastal cities and surrounding areas increasingly vulnerable to flooding by adding to the height that storm surge and breaking waves reach on the coast."
During the 21st century, the increases in sea level rise rate that have already occurred in the hotspot will yield increases in sea level of 8 to 11.4 inches by 2100. This regional sea level increase would be in addition to components of global sea level rise.
To determine accelerations of sea level, USGS scientists analyzed tide gauge data throughout much of North America in a way that removed long-term (linear) trends associated with vertical land movements. This allowed them to focus on recent changes in rates of sea-level rise caused, for example, by changes in ocean circulation. (Source: USGS, PR, 23 June, 2012) Contact: USGS, www.usgs.gov

The company is currently working on its first roll-to-roll manufacturing line installed in Dresden, Germany, to go in production in the third quarter of 2012. It has also kicked off a third financing round to raise 60 million euro from current and new investors for a new roll-to-roll 75 megawatt-peak production line.

Scientists at the U.S. DOE's Joint BioEnergy Institute announced last year they were working with new strains of Escherichia coli that could more easily digest biomass from switch grass for use in gasoline, diesel and jet fuels.
The USGS said it expected demand for biofuel products to increase as global economics search out alternatives to fossil fuels. The agency said "critical considerations" are made when examining energy derived from biofuels compared to the energy used to grow and process them.
In December, 2011, the U.S. DOE announced that, along with the USDA, it awarded $12.2 million for 10 separate grants that target improvements in biofuels and bioenergy crops. (Source: USGS) Contact: U.S. Geological Survey, www.usgs.gov
