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.
Bureaus within DOI have several specialized facilities, equipment and/or capabilities that are not readily available from the private sector that its collaborators may use under appropriate Facility Use Agreements. These assets, listed by bureau, include:
Bureau of Reclamation
Reclamation's extensive water storage, water delivery, and hydropower facilities offer unsurpassed laboratories for field tests, evaluations, research and demonstrations for water, power, or related needs. Reclamation's facilities and Laboratories include:
Bureau of Safety and Environmental Enforcement (BSEE)
Ohmsett is the Bureau of Safety and Environmental Enforcement's (BSEE) National Oil Spill Response Research and Renewable Energy Test Facility. This premier oil spill training facility is the only facility where full-scale oil spill response equipment testing, research and training can be conducted in a marine environment with oil under controlled environmental conditions (waves and oil types). Government agencies, academia, public and private companies can contract the use of Ohmsett as a research center to test oil spill containment/clean-up equipment and techniques, to test new designs in response equipment, and to conduct training with actual oil spill response technologies.
United States Fish and Wildlife Service
Fish Technology Centers provide leadership in development of new concepts, strategies, and technologies for science-based conservation and management of aquatic resources. Specialized facilities and programs exist for Genetics and Cryopreservation, Conservation Physiology and Ecology, Fish Nutrition and Diet Development, Fish Passage and Screening, and Captive Propagation Technology for Sensitive Species.
Fish Passage and Screening Laboratories support research into areas such as open-channel flume and swim tunnels and artificial streams, where researchers can simulate varied stream conditions for addressing a wide variety of questions on fish ecology, behavior, and life-history requirements relative to selected environmental factors.
Nutrition and Diet Development Laboratories allow for the manufacturing of experimental larval, fingerling, and broodstock fish feeds and the testing of many different kinds of ingredients to improve fish performance and quality. This program also develops specialized diets for use in captive rearing of endangered fish species like woundfin, razorback sucker, June sucker and Rio-Grande silvery minnow. Recent work includes development of plant-based fish feeds to reduce reliance on ocean forage fish for fish feed protein.
Conservation Genetics Laboratories support related conservation and management needs to the Service and its partners, including, but not limited to: 1) use of genetic DNA methods to meet real-time fishery needs to conserve and manage species; 2) assist with Endangered Species Act status reviews and recovery planning, via genetic monitoring and evaluation of listed populations and species; 3) establish and maintain genetic tissue/DNA repositories for imperiled species; 4) characterize diversity within and among wild populations.
Conservation Physiology and Ecology Laboratories focus on understanding the physiological requirements and tolerances of threatened and endangered species. Less-invasive or non-invasive tools, such as measurement of plasma sex steroid and ultrasound, are used to assess sex and stage of maturity and spawning readiness in both wild and captive populations of threatened and endangered species. Contract services available: blood chemistry, histology, proximate analysis, and radioimmunoassays.
