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.

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.

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.
Western Gulf of Mexico Lease Sale Yields $110 Million in High Bids on More Than 400,000 Acres
Office of the Secretary
Demonstrates Continued Commitment to Gulf of Mexico Energy Sources

NEW ORLEANS, LA -- As part of President Obama's all-of-the-above energy strategy to continue to expand safe and responsible domestic energy production, today's Western Gulf of Mexico Lease Sale 238 attracted $109,951,644 million in high bids for 81 tracts covering 433,823 acres on the U.S. Outer Continental Shelf offshore Texas. A total of 14 offshore energy companies submitted 93 bids.
“This sale underscores the President's commitment to create jobs and home-grown energy through the safe and responsible exploration and development of offshore energy resources,” said Interior Deputy Secretary Mike Connor. “The Gulf of Mexico has been and will continue to be a cornerstone of our domestic energy portfolio, with vital energy resources that spur economic opportunities and further reduce our dependence on foreign oil.”
Today's lease sale, which offered 21.6 million acres, builds on five previous sales held under the Obama Administration's Outer Continental Shelf Oil and Gas Leasing Program for 2012-2017 (Five Year Program). These five lease sales have offered more than 60 million acres for development, and garnered $2.3 billion in bid revenues.
"The Gulf of Mexico is one of the most productive basins in the world, and the Obama Administration's robust Five Year Program supports a balanced approach that encourages the development of the Gulf's offshore oil and gas resources, while protecting the human, marine and coastal environments and ensuring a fair return to the American people," said Connor.
Today's sale offered all unleased areas (excluding those located in the Flower Garden Banks National Marine Sanctuary) in the Western Gulf of Mexico planning area, including 4,026 tracts from nine to more than 250 miles off the coast, in depths ranging from 16 to more than 10,975 feet (five to 3,346 meters). BOEM estimates the lease sale could result in the production of 116 to 200 million barrels of oil and 538 to 938 billion cubic feet of natural gas.
Today, 167 of the blocks available for lease were located or partially located within three statute miles of the maritime and continental shelf boundary with Mexico. Leases issued on these blocks are subject to the terms of the U.S. - Mexico Transboundary Hydrocarbon Reservoirs Agreement and 24 of those blocks received bids.
BOEM established the terms for the leases offered in today's sale after extensive environmental analysis, public comment and consideration of the best scientific information available. The terms include measures to protect the environment, such as stipulations requiring that operators protect biologically sensitive features, as well as providing trained observers to monitor marine mammals and sea turtles to ensure compliance and restrict operations when conditions warrant.
The terms also continue a range of incentives to encourage diligent development and ensure a fair return to taxpayers, including an increased minimum bid for deepwater tracts, escalating rental rates and tiered durational terms with relatively short base periods followed by additional time under the same lease if the operator drills a well during the initial period.
Following today's sales, each bid will go through a strict evaluation process within BOEM to ensure the public receives fair market value before a lease is awarded.
