National Science Foundation Advisory Committee Offers New Vision for the Geosciences in Report "GEO Vision: Unraveling Earth's Complexities through the Geosciences"

Society stands at a crossroads. With growing problems such as resource depletion, energy sustainability, environmental degradation and climate change, can we protect the health of the planet while achieving widespread economic prosperity?

So asks a report released on October 15, 2009, by the National Science Foundation (NSF)'s Advisory Committee for Geosciences (AC-GEO): GEO Vision: Unraveling Earth's Complexities through the Geosciences.

For most of its history Earth has experienced vast alterations, states the report, in response to natural variations in our planet.

Humans, however, are now emerging as the dominant agent of change.

"It is essential going forward that we have the scientific tools and evidence to understand and anticipate how the Earth will be transformed in the future, and at what rate, in response to these growing pressures," says geoscientist George Davis of the University of Arizona, chair of the AC-GEO.

"To identify these influences and their potential impacts requires an understanding of the Earth, its history, and its systems that's grounded in basic science--a science that probes and ultimately defines the Earth's character."

Such basic research is the domain of the geosciences, which seek to advance a better understanding of Earth and its systems, states the GEO Vision report.

In the United States, NSF is the sole research agency, believes the AC-GEO, with the disciplinary breadth to comprehensively address these diverse challenges. The AC-GEO, NSF's directorate for geosciences, has three divisions: atmospheric and geospace sciences; earth sciences; and ocean sciences.

"It is NSF's geosciences directorate that must engage other NSF directorates and external partners in an ambitious research program that furthers our understanding of Earth, and provides the basis for objective and sound policy formulation and decision-making," says Arden L. Bement, Jr., NSF director.

The challenges ahead for the geosciences,

 the advisory committee found, are:

• understanding and forecasting the behavior of a complex and evolving Earth system;
• reducing vulnerability and sustaining life; and
• growing the geosciences workforce of the future.

The members of the AC-GEO believe that it's possible to meet these challenges, and to realize a GEO Vision of fostering a sustainable future, through a better understanding of our complex and changing planet.

"Earth is a dynamic marvel of complexity and beauty," says Tim Killeen, NSF assistant director for geosciences. "We as geoscientists must work to meet the challenge of understanding its many facets, and use that knowledge to advance our stewardship of its systems. The AC-GEO's report could not be more timely."

Society as a whole must make wise decisions regarding environmental and resource management, according to GEO Vision, using a grounded and rational set of guidelines.

Scientists and engineers will be called upon in the future to supply the scientific insights and predictive capabilities required to inform key policy decisions, many with long-lasting effects.

"Leading many of those discussions will be geoscientists," states the report, "who will share their understanding of the Earth system with the public and with decision-makers, providing the scientific knowledge that will ultimately guide society as it comes to understand its evolving relationship with the planet."

The AC-GEO's recommendations are to:

• Sustain and nurture fundamental geosciences disciplinary programs;
• Reach out in bold new directions, engaging and incorporating other disciplines;
• Embrace a culture that recognizes that transformational research involves an element of risk;
• Invest wisely and responsibly manage the next generation of tools, technologies, and techniques, including advanced computation to enable cutting-edge research;
• Communicate the critical role the geosciences play in reducing risks from natural hazards;
• Build effective and enduring partnerships within NSF as well as with other federal agencies, the private sector, international organizations, and with other institutions outside U.S. borders;
• Recognize the explicit need for the geosciences to adopt the challenge of increasing the resiliency of natural systems;
• Build bridges between geoscience researchers and the K-12 classroom to promote early childhood and young-adult understanding of geosciences concepts;
• Create a broad and diverse cadre of geosciences researchers who can use creative approaches to geosciences education and literacy at all levels;
• Convey central, and potentially pivotal, geosciences research and findings to policymakers and thought leaders for building a sustainable future.

"We as a society face a daunting task," says Killeen. "Through the help of the AC-GEO, we will make great strides in realizing a new vision for the geosciences--and for the future of our planet."

About GEO

The Directorate for Geosciences (GEO) is one of seven research arms within the National Science Foundation. Its mission is to support research in the atmospheric, earth, and ocean sciences. As the principal source of federal funding for university-based fundamental research in the geosciences, GEO addresses the nation's need to understand, predict, and respond to environmental events and changes to use Earth's resources wisely. Basic research in the geosciences advances scientific knowledge of Earth's environment, including resources such as water, energy, minerals, and biological diversity. GEO-supported research also advances our ability to predict natural phenomena of economic and human significance, such as climate changes, weather, earthquakes, fish-stock fluctuations, and disruptive events in the solar-terrestrial environment.

Millions of Jellyfish in Jellyfish Lake Found to “Biomix,” Churning Nutrients of the Lake

"Biomixing" by floating animals churns waters in oceans, seas, lakes: Through this process, jellyfish and other zooplankton--where they're abundant, as they are in Jellyfish Lake--may in some way affect Earth's climate. "Biomixing may be a form of 'ecosystem engineering' by jellyfish, and a major contributor to carbon sequestration, especially in semi-enclosed coastal waters," says marine scientist Michael Dawson.
