Washington, DC— There is considerable opportunity for generating wind power in the open ocean, particularly the North Atlantic, according to new research from Carnegie’s Anna Possner and Ken Caldeira. Their work is published by Proceedings of the National Academy of Sciences.

Because wind speeds are higher on average over ocean than over land, wind turbines in the open ocean could in theory intercept more than five times as much energy as wind turbines over land. This presents an enticing opportunity for generating renewable energy through wind turbines. But it was unknown whether the faster ocean winds could actually be converted to increased amounts of electricity.

Washington, DC— Carnegie’s Ken Caldeira and Geeta Persad are co-recipients of one of nine National Science Foundation grants for research on how humans and the environment interact. The nine projects were awarded $13 million overall.

The Coupled Dynamics of Natural and Human Systems program “considers humans and the environment as one interconnected system,” said the NSF when announcing the grants. The awardees were selected because they “look at ways in which people deal with environmental processes in a range of settings, including coasts, woodlands, and cities.”

As Carnegie’s grantees, Caldeira and Persad aim to help countries optimize how they meet their commitments

Global biological diversity is under enormous and increasing threat from habitat loss caused by land use and climate change. Responding to this problem requires strategies that integrate elements of governance, economics, human welfare, and other societal factors. It also requires the use of geographically explicit approaches to generate safe havens for biodiversity, both in the long-term and as immediate barriers to the ongoing extinction crisis.

Prioritization of new regions for protection is often undertaken with incomplete and/or outdated information on the geography of biodiversity.  In response, Greg Asner and colleagues have created and utilized a novel capability to map

Chris Field is a co-principal investigator of the Jasper Ridge Global Change Experiment at the Jasper Ridge Biological Preserve in northern California. The site, designed to exploit grasslands as models for understanding how ecosystems may respond to climate change, hosts a number of studies of the potential effects from elevated atmospheric carbon dioxide, elevated temperature, increased precipitation, and increased nitrogen deposition. The site houses experimental plots that replicate all possible combinations of the four treatments and additional sampling sites that control for the effects of project infrastructure. Studies focus on several integrated ecosystem responses to the

In March 2014, a technical support unit (TSU) of ten, headquartered at Global Ecology, had successfully completed a herculean management effort for the 2000-page assessment Climate Change 2014: Impacts, Adaptation, and Vulnerability, including two summaries. They were issued by the United Nations (UN) Intergovernmental Panel on Climate Change (IPCC), Working Group II co-chaired by Chris Field, Global Ecology director, with science co-directors Katie Mach and Mike Mastrandrea managing the input of over 190 governments and nearly 2,000 experts from around the world.

The IPCC, established in 1988, assesses information about climate change and its impacts. In September 2008, Field was

Coral reefs are havens for marine biodiversity and underpin the economies of many coastal communities. But they are very sensitive to changes in ocean chemistry resulting from greenhouse gas emissions, as well as to pollution, warming waters, overdevelopment, and overfishing. Reefs use a mineral called aragonite, a naturally occurring form of calcium carbonate, CaCO3, to make their skeletons.  When carbon dioxide, CO2, from the atmosphere is absorbed by the ocean, it forms carbonic acid—the same stuff that makes soda fizz--making the ocean more acidic and thus more difficult for many marine organisms to grow their shells and skeletons and threatening coral reefs globally.

Monitoring tropical deforestation and forest degradation with satellites can be an everyday activity for non-experts who support environmental conservation, forest management, and resource policy development.

Through extensive observation of user needs, the Greg Asner team developed CLASlite ( the Carnegie Landsat Analysis System--Lite) to assist governments, nongovernmental organizations, and academic institutions with high-resolution mapping and monitoring of forests with satellite imagery.

CLASlite is a software package designed for highly automated identification of deforestation and forest degradation from remotely sensed satellite imagery. It incorporates state-of-the

Joe Berry has been a Carnegie investigator since 1972. He has developed powerful tools to measure local and regional exchanges of carbon over spaces of up to thousands of square miles. He uses information at the plant scale to extrapolate the carbon balance at regional and continental scales.

According to ISI's Web of Science, two of Joe Berry's papers passed extremely high, rarefied citation milestones. The 1980  paper “A biochemical model of photosynthetic CO2 assimilation in leaves of C3 species,” has had over 1,500th citations. His 1982 paper “On the relationship between carbon isotope discrimination and the intercellular carbon dioxide concentration in leaves” passed its 1,
