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 Torch/Platform Irene Oil Spill Trustee Council continues to implement a number of restoration projects addressing injuries to seabirds arising from a 1997 oil spill from a pipeline into the Santa Barbara Channel. These restoration projects focus on Brown Pelicans, Brandt's Cormorants, Pigeon Guillemots, Black Oystercatchers, and Western Gulls, the species most heavily impacted by the oil spill. In addition to the U.S. Fish and Wildlife Service and the Bureau of Land Management, the Trustees include two California state agencies, NOAA, and the U.S. Air Force.
In 2010, the Trustees directed $1.2 million of settlement funds to the Bureau of Land Management to establish the Seabird Colony Enhancement Project over a 300-mile long project area. The goal of the project is to restore populations of nesting and roosting seabirds by reducing multiple kinds of human disturbances to colonies and to monitor progress toward recovery of seabird populations since the spill. The design of this effort is modeled after the successful work of the Command Oil Spill Trustee Council to establish a similar Seabird Protection Network further north on the California coast near San Francisco from Monterey County to Sonoma County.
The Trustees conducted aerial overflights of the Central California coast from Point Sur (Monterey County) south to Point Conception (Santa Barbara County) in late May to document the existing population levels of seabird colonies. An education specialist from the California Department of State Parks and Recreation is implementing outreach and media programs to involve key groups within the general public, such as fishermen, recreation groups and pilots. Through outreach efforts such as public service announcements, information kiosks, and displays at highly visited beaches and bluffs, Trustees can inform the public about seabirds, their biology, habitat requirements for nesting and roosting, and the ways that people can contribute to assisting recovery of seabird colonies in the project area through their own behavior and concern.
Bird biologists from a non-governmental organization, PRBO Conservation Science, have mapped permanent locations from which to observe reproductive success at nesting colonies at least weekly during the nesting season in 2011 and beyond. BLM and PRBO are working jointly with local communities in the impact area to establish long-term citizen-science cadres of local residents to monitor important areas of seabird concentrations throughout the year. In addition, the Trustees are working with Federal, State, county, and municipal law enforcement agencies to educate the public on the legal basis for protecting seabirds from human disturbances and how to avoid unintended disturbances to seabirds.
The trustees are especially concerned about the seabird colonies closest to population centers because of the potential detrimental impact of human activity on seabird populations. Specifically, Trustees are focusing on colonies near the Vandenberg Air Force Base, the Diablo Canyon nuclear power plant, and Morro Rock near San Luis Obispo. These activities are providing essential information about eventual needs for access control and habitat improvements for seabird colonies in the project area. Observations will extend to remote colonies in southern Monterey County in future seasons.
