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.
Secretary of the Interior Salazar Highlights Administration Plans to Help Protect Coral Reefs
Last edited 4/25/2016
WASHINGTON, D.C. – Secretary of the Interior Ken Salazar, co-chair of the U.S. Coral Reef Task Force, today told task force members that the Obama Administration is committed to quick action on global warming—a key threat to coral reefs—and that the economic stimulus package, clean energy and community service programs and ethic of preserving natural treasures add up to good news for coral reef conservation.
“We will move ahead with a new energy frontier for the United States of America and for the world that will feature clean energy and address climate change,” said Salazar. “Addressing climate change is a critical aspect of protecting coral reefs across the world and I know it will be high on the agenda of this task force,” he told a meeting of officials at Interior Department headquarters.
Nancy Sutley, the new chair of the President's Council on Environmental Quality, also stressed the Administration's commitment to addressing global warming and promoting ocean conservation in general and protection of coral reefs in particular.
Secretary Salazar noted that the U.S. Department of the Interior manages 5 million acres of coral reefs. The Department's ocean responsibilities also include 1.7 billion acres of the Outer Continental Shelf; 177 island and coastal National Wildlife Refuges; 34 million acres in 74 coastal National Parks; more than 35,000 miles of coastline; co-management with NOAA of the 89 million-acre Papahanaumokuakea Marine National Monument in Hawaii; and management, in part with NOAA, of the 70 million acres in the three new Pacific Marine National Monuments.
The Coral Reef Task Force was established in 1998 to lead U.S. efforts to preserve and protect coral reef ecosystems. It includes leaders of 12 Federal agencies, seven U.S. States, Territories, Commonwealths, and three Freely Associated States.
The Secretary expressed support for the service of the task force, which he noted was started by President Clinton and continued to work under President Bush. He extended particular appreciation to the governors of U.S. territories, which contain world-class coral reefs. Key participants in the meeting today were American Samoa Governor Togiola Tulafono; CNMI Governor Ben Fitial and Guam Governor Felix Camacho.
Nik Pula, Acting Deputy Assistant Secretary of the Interior for Insular Affairs, co-chaired the meeting along with Mary Glacken, Acting NOAA Administrator. Pula also testified this afternoon for the Department of the Interior on reauthorization of the Coral Reef Conservation Act.
The testimony before the House Natural Resources Subcommittee on Insular Affairs, Oceans and Wildlife
conveyed the Secretary's appreciation for the fact that the bill includes statutory authorization for Department of the Interior coral reef conservation programs, and a damage assessment and compensatory recovery process for all of the coral reefs.
