Thomas LaPoint, Director

The Institute of Applied Sciences (IAS) provides research and educational programs that address the natural and human resource issues facing Texas, the nation and the world. With an emphasis on water, land, people and communities, IAS seeks to explore resources for the future. The strength of IAS is its interdisciplinary approach to instruction, research and community service.

The Institute is presently organized into four program areas: water resources, environmental chemistry, remote sensing and land use analysis, and archaeology. The institute provides educational programs for students seeking training in environmental studies and other applied science areas. It also offers to the public continuing education programs such as workshops, minicourses, seminars and symposia to the public.

Activities include basic and applied studies in a variety of fields in the applied sciences, including the analysis of trace organic and inorganic compounds in air, water, soils, waste materials and biological samples; toxicology; land use analysis via remote sensing and Geographic Information Systems (GIS); archaeological reconnaissance and salvage; and water resources management. The institute is particularly active in the coordination and execution of joint research projects with industry and governmental agencies in these areas. The following centers support this role.

Aquatic Toxicology and Reservoir Limnology

UNT has one of the best aquatic toxicology laboratories in the Southwest. The lab is equipped to conduct acute and chronic toxicity tests with freshwater and marine organisms, and conducts research for a variety of industries and municipalities on the effects of chemicals on aquatic life. The reservoir limnology program conducts water quality research on rivers and reservoirs throughout Texas. The program has vehicles, boats, and sampling equipment for conducting intensive water quality surveys. Analytical capabilities are available for analyses of water contaminants.

Remote Sensing and Land Use Analyses

The Center for Remote Sensing (CRS) applies remote sensing technologies and Geographic Information Systems (GIS) to land use and water resources issues. The center uses state-of-the-art computer facilities to conduct basic and applied research on remote sensing data collection, image enhancement, classification and analyses. The primary thrust is to find interrelationships between local or regional land use patterns and water quality. The center has a fully equipped Earth Resources Data Analysis Systems (ERDAS) and ARC/INFO capabilities.

Ecological Risk Assessment/Water Research Field Station

UNT has two of the few facilities in the US designed to assess, under field conditions, the effects of new chemicals and pesticides on aquatic ecosystems. The pond facility consists of 48 aquatic testing ponds of 0.1 acre each and 52 1,000- and 10,000-liter microcosms. The Artificial Stream Facility has 12 five-meter replicate streams, each capable of being colonized by aquatic species. The Water Research Field Station (WRFS) is specifically designed to assess the impacts of agrichemicals on aquatic populations and communities. The research conducted at these facilities assesses the hazards of chemicals prior to their use in the general environment. The field station and stream facility are supported on campus by a biological and residue analysis laboratory with state-of-the-art equipment such as computer interfaced gas chromatographs.

Environmental Chemistry

The Environmental Chemistry Laboratory conducts research on the fate of chemicals in the environment. This lab has modern analytical equipment for the analysis of metals and organic chemicals in water and soils. The laboratory examines the physical and chemical processes that control the distribution of chemicals in soil, surface water, ground water and the atmosphere. Modern chromatography and spectroscopy instrumentation for the measurement of organic and inorganic contaminants are available.

Environmental Archaeology and Geology

The Institute's faculty are experienced in the design and implementation of cultural resource management projects. The emphasis is on reconstruction of past environments and cultural ecology as part of archaeological research. Quaternary geologic studies are supported by a sediment-soils laboratory that has full capabilities for mechanical, chemical and mineralogical analyses of samples from archaeological sites and natural deposits. A comparative osteology lab maintains an extensive collection of animal skeletons for zooarchaeological research and forensic analysis. An off-campus lab includes facilities for artifact washing and cataloging, detailed analysis, and artifact curation. Environmental geology, groundwater hydrology, geomorphology, soil science, sedimentology and hydrology research are also conducted.

Environmental Modeling

This laboratory develops and uses mathematical models and computer simulations for the assessment of risks and impacts of anthropogenic stressors on environmental and ecological systems. Research is carried out at the local, landscape, regional and global scales. The main themes are linking of environmental models of Remote Sensing/GIS
and application to landscape and regional dynamics; global change effects on tropical forests and savannas; integration of modeling to policy science and relation to environmental issues and development; and integration of modeling with other technologies like optical sensors, data acquisition electronics, and high performance computers.
