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.
Salazar, Beaudreau Announce Western Gulf of Mexico Oil and Gas Lease Sale
Final Notice of Sale Outlines Lease Terms That Will Promote Safe and Responsible Development of Gulf Energy Resources
WASHINGTON — Department of the Interior Secretary Ken Salazar and Bureau of Ocean Energy Management (BOEM) Director Tommy P. Beaudreau today announced that BOEM will hold the first oil and natural gas lease sale in the Gulf of Mexico since the Deepwater Horizon explosion and oil spill. This announcement is consistent with steps President Obama announced in May, 2011 to expand domestic oil and gas production safely and responsibly.
This sale follows BOEM's completion of a supplemental environmental impact statement analyzing the effects of the Deepwater Horizon spill on the Western Gulf of Mexico. Lease Sale 218 will be held in the Louisiana Superdome in downtown New Orleans on Dec. 14, 2011. The sale will include all available unleased areas in the Western Gulf Planning Area offshore Texas.
“This sale is an important step toward a secure energy future that includes safe, environmentally-sound development of our domestic energy resources that will continue to reduce our dependence on foreign oil and create jobs here at home,” Secretary Salazar said. “Since the Deepwater Horizon spill, we have strengthened oversight at every stage of the oil and gas development process, including deepwater drilling safety, subsea blowout containment, and spill response capability. Exploration and development of our Western Gulf's vital energy resources will continue to help power our nation and drive our economy.”
“BOEM was established to oversee the responsible development of the nation's offshore resources and to ensure a fair return for the American taxpayer through lease sales.” said Director Beaudreau. “We are committed to balanced decision-making by ensuring that appropriate consideration of the environment is given in every case. The decision to hold this sale was made after careful analysis of the best scientific information available regarding the effects of the Deepwater Horizon oil spill.”
Lease Sale 218, the last remaining Western Gulf Planning Area sale scheduled in the 2007-2012 Outer Continental Shelf (OCS) Oil and Natural Gas Leasing Program, encompasses 3,913 unleased blocks covering more than 21 million acres. The blocks are located from nine to about 250 miles offshore, in water depths ranging from 16 to more than 10,975 feet (5 to 3,346 meters). BOEM estimates the lease sale could result in the production of 222 to 423 million barrels of oil and 1.49 to 2.65 trillion cubic feet of natural gas.
The Final Notice of Sale (FNOS) gives the lease terms and economic conditions for this particular sale. It includes an increase in the minimum bid amount for blocks in water depths of 1,312 feet (400 meters) and greater from $37.50 to $100 per acre. The minimum bid amount for leases in the shallower water depths will remain at $25 per acre.
This change is based on a rigorous historical analysis of the last 15 years of lease sales in the Gulf of Mexico. The analysis, adjusted for energy prices at time of each sale, demonstrates that leases that received high bids of less than $100 per acre have experienced virtually no exploration and development activities. Raising the minimum bid will discourage companies from inventorying offshore acreage that they are unlikely to explore during the lease term.
The lease sale package also includes environmental stipulations requiring that operators protect biologically sensitive features, as well as marine mammals and sea turtles. These stipulations will require trained observers to ensure compliance and restrict operations when conditions warrant.
