FACILITIES

 

In fall, 2000, the university created a new Type II Center, the Land Use and Environmental Change Institute (LUECI), which is a collaborative, interdisciplinary venture.  Participants include the P.I. and the Departments of Geological Sciences, Geography, and Anthropology, with collaboration from the Center for Latin American Studies.  The new labs play a vital role in LUECI research and teaching.  The creation of about 1200 square feet of expanded GIS/Remote Sensing laboratories has occurred with upgraded facilities and new workstations, all of which have the necessary software packages installed. A large format scanner and printer will be available for this project and will be purchased through Southworth’s start-up costs.

Facilities in this lab allow for spatial analysis of data collected from Earth-observing remote sensing platforms and field studies utilizing the latest hardware alongside the most current software packages availible. With over 3 terabytes (TB) of redundant network-attached storage, these labs house data related to a number of differnt research projects headed by memembers of several departments campus-wide. Stored in a central location, these files are easily accessible to researchers within the lab environs, but kept strictly segregated from the outside world by numerous hard and soft firewalls and dedicated network paths. This ensures maximum combined efforts can be brought to bear on data sets without comprimising the integrity of projects, or the soverignty of the principle investigator. The LUECI laboratories are open to all students and faculty who have interests in climate-environment-human interactions, fostering collaborative research among individuals from diverse disciplines.

Existing equipment and instruments for fieldwork includes a field spectroradiometer, navigation and surveying instruments, differential and stand-alone GPS receivers, cartographic instruments, and field surveying instruments.

A secondary facility, LUECI's Florida Institute of Paleoenvironmental Research (FLIPER) is housed in 2500 ft2 of renovated space in Williamson Hall (Geological Sciences). The laboratory is designed for comprehensive paleoenvironmental study of sediment cores from lake, wetland, and marine sites. The lab has a cold room for sediment core storage, and is equipped with state-of-the-art instrumentation, including a Geotek Multi-Sensor Core Logger (MSCL) that measures magnetic susceptibility, p-wave velocity, and sediment density on intact cores, and can produce high-resolution digital images of sediment sections. The lab also possesses a Micromeritics Sedigraph for particle size analysis.

FLIPER benefited from consolidation of equipment previously housed in several University of Florida departments. Existing equipment and instruments include field gear (e.g., square-rod corers and Avon inflatable boats) for collection of lake sediment cores, UIC coulometers for total and inorganic carbon analysis, a Carlo-Erba NA 1500 analyzer for total carbon, nitrogen, and sulfur analyses, a Bran-Luebbe Autoanalyzer for total phosphorus and biogenic silica analysis, three EG & G Ortec well-type gamma detectors for 210Pb dating and environmental radiation measurements (e.g. 226Ra), a VG/Micromass Prism Series II mass spectrometer and Finnigan MAT 252 mass spectrometer for measurement of d18O, d13C, and d15N in carbonate and organic matter samples, and microscopes for picking microfossils. In a joint effort with the Soil and Water Sciences Department, LUECI will purchase a new Delta+ XL mass spectrometer and GC with interface that will enable measurement of compound-specific isotope ratios in sediment organic matter.
