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.
The large scale and complexity of the invasive species issue frequently results in inaction; there is a common belief that, once established, it is no longer logistically or financially feasible to eradicate or control populations of invasive species. This belief limits innovative thinking, as well as funding for the scientific and technological advancements that could turn a seemingly intractable situation into a resolvable problem. There is a need to: (a) overcome limiting beliefs about scientific and technical capacities for invasive species prevention and management and (b) foster innovative problem solving.
MP Action 6.2: Working with scientific and technical institutions, organize and co-host an Innovation Summit that: (a) promotes scientific, technical, and technological advances that can facilitate invasive species prevention, eradication, and control and (b) identifies priority needs for further advances in science and technology that can provide solutions to some of the worst invasive species challenges in the U.S. and elsewhere.
Progress report: The first annual Innovation Summit was held on December 5th, 2016 at the Smithsonian Institution. Click on the links below for more details. The presentations and associated recordings are available here.
