The following are USGS research projects offering an opportunity for Cooperative Research and Development Agreement (CRADA) partnerships. A CRADA is an agreement between one or more Federal agencies and one or more non-Federal agencies to work together in research or developmental activities. CRADAs permit both partners to share information in a protected environment and offer incentives to the non-Federal partner(s) to commercialize the resulting product of the effort.
A CRADA is a Cooperative Research and Development Agreement. It is a written agreement between a private company and a government agency to work together on a project. By entering into a CRADA, the Federal government and non-Federal partners can optimize their resources and cost-effectively perform research by sharing the costs of this research. The collaborating partner agrees to provide funds, personnel, services, facilities, equipment or other resources needed to conduct a specific research or development effort while the Federal government agrees to provide similar resources but not funds directly to the partner.
As a research and information laboratory of the Federal government, the U.S. Geological Survey (USGS) is committed to making its developments readily available to customers within the private sector. The USGS is the Nation's premier earth science agency, providing unique scientific data and technology in the areas of natural hazards, environment, resources, and information. Often USGS research and information activities lead to developments that have significant commercial applications and that can help increase the global competitiveness of our domestic economy. The agency uses a proactive technology transfer program to encourage the adoption and use of these developments. In addition, the agency welcomes collaborative opportunities with private industry.
Introduction The Florida Everglades is a vast, diverse wetland ecosystem characterized by small ground-surface slopes, slowly moving surface waters, and dense aquatic vegetation. Both submersed and emergent vegetation are found in sawgrass and cattail marshes, wet prairies, and sloughs. The south Florida ecosystem has been greatly altered during the last 100 years. A complex water-management system that includes levees, canals, pumps, and water-control structures now regulates flooding and provides a steady supply of fresh water to urban areas and agriculture. Drainage projects have diverted much of the water that originally flowed slowly southward from Lake Okeechobee through the Everglades. Restoration and management of the Everglades ecosystem requires understanding and manipulating the amount and timing of water flows throughout the ecosystem. The spatial and temporal distribution of water and water-borne contaminants in the Everglades must be understood if degradation of the ecosystem is to be halted and reversed. To understand how water moves through the Everglades, it is necessary to quantify the forces affecting the flow. The resistance exerted on the flow by the vegetation through which the water moves is one of the dominant but least understood forces affecting Everglades surface-water flows. The aquatic vegetation of the Everglades affects both the depth of water and the rate at which it moves. The presence of living and dead plant material in the water column creates drag forces on the moving water. Water flows most slowly and the water-surface slope is largest in areas where vegetation is most dense.
Scientists at the U.S. Geological Survey have developed a computer-based temperature control and video overlay system for use with the diamond anvil cell. The diamond-anvil cell (DAC) is a means for subjecting samples to very high pressures in laboratory experiments. For example, pressures to 100 kilobars can be achieved using the device. In addition, the DAC can subject samples to temperatures ranging from -200 to 1200° C.
