Mercury's surface in "enhanced color," a color scheme created to emphasize color differences. This is not what Mercury would look like to the human eye, but by applying mathematical analysis to images, color differences can be accentuated beyond those visible to a person.
Mount Rushmore National Memorial under construction.
The workers had to endure conditions that varied from blazing hot to bitterly cold and windy. Each day they climbed 700 stairs to the top of the mountain to punch-in on the time clock. Then 3/8 inch thick steel cables lowered them over the front of the 500-foot face of the mountain in a "bosun chair." Despite the dangers, no one was killed during the project.
Otters in Glacier Bay National Park and Preserve, Alaska.
The sea otter population of Glacier Bay has increased dramatically in the past 20 years. Ecologists consider sea otters a keystone species here. Otters consume vast quantities of clams, urchins, crabs, and other invertebrates and their presence creates ripples through the ecosystem. NPS photo.
Every day someone like you becomes a wildland wildfire fighter, a teacher, a trail-builder, a museum curator, or a park ranger. Discover your opportunities in national parks. Come to play. Come to learn. Come to serve. Develop your environmental leadership skills. Find a job. Be the next generation to preserve and protect these great places.
With more than 80% of Americans living in urban areas, urban parks are more important than ever. The father of American landscape architecture, Frederick Law Olmsted, said of urban parks:
It is one great purpose of the Park to supply to the hundreds of thousands of tired workers, who have no opportunity to spend their summers in the country, a specimen of God's handiwork that shall be to them, inexpensively, what a month or two in the White Mountains or the Adirondacks is, at great cost, to those in easier circumstances.
Obama Administration Announces New Partnership on Unconventional Natural Gas and Oil Research
WASHINGTON – Today, three federal agencies announced a formal partnership to coordinate and align all research associated with development of our nation's abundant unconventional natural gas and oil resources. The partnership exemplifies the cross-government coordination required under President Obama's Executive Order released earlier today, which created a new Interagency Working Group to Support Safe and Responsible Development of Unconventional Domestic Natural Gas Resources. This new partnership will help coordinate current and future research and scientific studies undertaken by the U.S. Department of Energy, the U.S. Environmental Protection Agency and the U.S. Department of the Interior – better positioning the Obama administration to ensure that continued expansion of natural gas and oil production happens safely and responsibly as part of an all-of-the-above approach to American energy in which science plays a guiding and critical role. The Memorandum of Agreement outlining this coordination is available here.
As the President has made clear, domestic natural gas and oil resources will continue to play a key role in America's energy future. Already, technological advancements like hydraulic fracturing – innovation supported by public research – have allowed development of previously uneconomic natural gas and oil deposits. In fact, since 2008, U.S. oil and natural gas production has increased each year. In 2011, U.S. crude oil production reached its highest level in 8 years, increasing by an estimated 110,000 barrels per day over 2010 levels to 5.59 million barrels per day. And U.S. natural gas production grew in 2011 as well – the largest year-over-year volumetric increase in history – easily eclipsing the previous all-time production record set in 1973. Overall, oil imports have been falling since 2005, and oil import dependence declined from 57 percent in 2008 to 45 percent in 2011 – the lowest level since 1995.
As the United States continues to expand domestic natural gas and oil production, it is critical that the public have full confidence that the right safety and environmental protections are in place – guided by the best available science. Leveraging each agency's core competencies and strengths will enhance efforts to explore the significant new resource development opportunities made possible in recent years by hydraulic fracturing and other new technologies, and meet high-priority challenges in a coordinated and common-sense way.
“Science, research and innovation continue to play a vital role in our efforts to further expand oil and gas production in the United States and make sure it's done safely and responsibly,” said Department of the Interior Deputy Secretary David J. Hayes. “Improvements in technologies like hydraulic fracturing are responsible for greatly increasing our capacity to develop America's abundant unconventional resources in recent years. Through a close collaboration across the government that reduces redundancy and streamlines our research, we are positioning the Obama administration to best meet the critical need of increasing public understanding and public confidence of these critical technologies so that we can continue safe and responsible exploration and production for many decades to come.”
“The development of American shale gas resources is having a transformative impact on the U.S. energy landscape, helping to improve our energy security while spurring economic development and job creation around the country,” said Acting Under Secretary of Energy Arun Majumdar. “The Energy Department remains committed to the safe and responsible development of this American resource, and continued cooperation between government and private industry partners under President Obama's all-of-the-above approach to American energy.”
"We are moving into a new era of American energy, one that has the potential to create jobs, strengthen our energy independence and security, and cut pollution. President Obama has created this interagency working group to ensure that these energy innovations happen safely and responsibly, without compromising the environment or the health of the American people," said EPA Deputy Administrator Bob Perciasepe. "We will continue to rely on the best available science to oversee the responsible development of these energy sources."
A primary goal of this effort will be to identify research topics where collaboration among the three agencies can be most effectively and efficiently conducted to provide results and technologies that support sound policy decisions by the agencies responsible for ensuring the prudent development of energy sources while promoting safe practices and human health. The new research partnership is an example of the Obama Administration's effort to coordinate activities across the federal government to support development of our abundant domestic natural gas resources in a safe and responsible way. Today the Administration announced that a broader set of activities will be coordinated under an Executive Order issued by President Obama to create a new Interagency Working Group to Support Safe and Responsible Development of Unconventional Domestic Natural Gas Resources.
