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.
Action 2.6: Under the auspices of the Arctic Council’s Conservation of Arctic Flora and Fauna (CAFF) Invasive Species Working Group, work with international partners to develop a strategy and action plan for the prevention and management of invasive species across the Arctic region.
The project is being accomplished under the guidance of the Arctic Council’s Conservation of Arctic Flora and Fauna (CAFF) and Protection of the Arctic Marine Environment (PAME) working groups. Representatives of the NISC Secretariat, U.S. Fish and Wildlife Service, U.S. Department of State, as well as a PAME representative based at the National Oceanic and Atmospheric Administration, serve on the project Steering Committee.
This effort is particularly urgent for the Arctic region. Rapid climate change is making the region more vulnerable to invasive species introductions, and at the same time a rapid increase in human activity and transit and energy development in the region is increasing the chance of introduction of new and invasive species. There is an immediate opportunity, already largely lost in many other regions of the world, to proactively build resilience to the risks posed by invasive species to the Arctic’s unique social, economic, and environmental systems.
