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.
Hayes, Ulmer Continue Dialogue on Improving Decision-Makers' Access to Science in Arctic
Office of the Secretary
WASHINGTON, D.C. – The Department of the Interior today hosted a meeting of top federal decision-makers, members of the federal government's science community, and outside experts from nongovernmental organizations, industry, academia, Alaska Native organizations, and state and local government to continue discussing ways to enhance collaboration between the scientific community and decision-makers in the Arctic.
Led by Deputy Secretary David J. Hayes and Fran Ulmer, Chair of the U.S. Arctic Research Commission and former chancellor of the University of Alaska, Anchorage, today's meeting was the third in a series of workshops to discuss how to better optimize the availability of relevant scientific information for federal decision-makers and, more generally, to promote a more interactive dialogue between scientists and decision-makers involved in the Alaska Arctic.
“As we work toward a long-term management framework for the Arctic, we must recognize both the resource potential of the region and the irreplaceable natural and cultural resources it contains,” said Deputy Secretary Hayes. “We are exploring ways to develop a landscape-scale approach to the Arctic that cuts across agencies, jurisdictions, and boundaries and takes into account the traditional knowledge of Native communities.”
“It is essential that we make every effort to address the future of the Arctic in an integrated manner that cuts across agency and disciplinary lines,” said Ulmer. “Research and planning are important building blocks of this approach, and that's why these workshops that bring together policy makers, land managers, community leaders, and scientific experts are necessary to discuss how best to deliver relevant scientific information to officials responsible for making decisions related to energy development in Alaska.”
Other meeting participants included high-level officials and scientists from the Departments of Interior, Commerce, Agriculture, Homeland Security, Transportation, the Environmental Protection Agency, the Office of the Federal Coordinator for Alaska Natural Gas Transportation Projects, and the White House Office of Science and Technology Policy. Also participating were senior representatives from state and local government, Alaska Native organizations, the U.S. Arctic Research Commission, the Interagency Arctic Research Policy Committee, non-governmental organizations, industry, and academia.
