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.
Ocean Energy Safety Advisory Committee to Hold First Meeting
Office of the Secretary
Last edited 4/26/2016
WASHINGTON – Secretary of the Interior Ken Salazar and Bureau of Ocean Energy Management, Regulation and Enforcement (BOEMRE) Director Michael R. Bromwich today announced that the Ocean Energy Safety Advisory Committee (OESC) will hold its first public meeting on Monday, April 18, 2011.
“The safe, responsible and appropriate development of our nation's offshore oil and gas resources requires a thoroughly coordinated and comprehensive approach,” Secretary Salazar said. “The Safety Advisory Committee will provide a vital forum to evaluate the latest scientific and technical information on ocean energy safety and recommend the most effective approaches to drilling and workplace safety, well intervention and containment and oil spill response.”
“This Committee is a key component of a long-term strategy to address on a continuing basis the technological needs and inherent risks associated with offshore drilling, and deepwater drilling in particular,” said Director Bromwich. “The challenge facing government and industry in the months and years ahead is to ensure that we do not once again become complacent about the risks of offshore drilling, but rather that we continue to make progress in developing state-of-the-art safety, containment and response capabilities.”
The OESC is a public federal advisory body of the nation's leading scientific, engineering and technical experts. Chaired by former Sandia National Laboratory Director Tom Hunter, the group consists of 15 members from federal agencies, the offshore oil and gas industry, academia and various research organizations who will represent their collective viewpoint on ocean energy safety. The Committee will provide critical policy advice to Secretary of the Interior through the BOEMRE Director on improving all aspects of ocean energy safety.
The meeting is open to the public, and will begin at 8:30 a.m. at U.S. Access Board, 1331 F Street, N.W., Suite 800, Washington, D.C. 20004.
