The basic objective of the Department of Geosciences Graduate Program is to provide students with a broad fundamental background in geosciences as well as an in-depth emphasis in a particular specialty.
The Master of Science degree (thesis option) is designed for students desiring research experience in a specific area of the geosciences. This degree will prepare the student for professional employment in the energy, mining, or environmental industries or government, as well as for those seeking a doctoral degree. The Master of Science degrees (non-thesis options) are designed for students who seek employment in the environmental industry, and the industrial application of Geographic Information Systems (G.I.S.).
The Doctor of Philosophy degree emphasizes basic research in one of the specialties in geosciences and is designed to prepare students for advanced positions in the energy, environmental or mining professions in industry or government, or for positions in academia.

Network access to a variety of LINUX workstations, Macintosh and PC computers is available. Parallel processing is done on a state of the art LINUX cluster with 42 processors and 3 terrabytes of disk.
Core viewing and subsurface data analysis lab. A large-scale scanner for digitizing well log data is also available.
Field equipment for measuring ground and surface water flow and chemistry, including borehole bailers, electric water level meter, FlowProbe hand-held flow meter, Hach DREL 2010 Basic Water Quality Lab (field spectrophotometer, pH and salinity meters), and YSI-85 DO/salinity/conductivity meter. Software for modeling water flow and transport, including general interfaces GMS and ArgusOne, Hydrus-2D (unsaturated flow and transport), TOUGH2 and Tetrad (2-3D multiphase flow and transport), and many public-domain models. Hardware and software for visualizing model results, including SGI O2 and Linux workstations, GoCAD and IBM DataExplorer software.
The Geochemical labs house sample preparation and analytical facilities. The sample prep lab uses multi-acid digestion and metaborate-tetraborate fusion techniques to take rock samples into solution for analysis. The analytical lab hosts the following instruments: 1) A Perkin-Elmer Optima 3300 DV inductively coupled plasma optical emission spectrometer (ICP-OES) instrument, with both radial and axial determination modes, which permits rapid determination of major and trace elements in rocks and water samples. 2) A Perkin-Elmer Sciex Elan 6100 DRC inductively coupled plasma mass spectrometer (ICP-MS), used for trace and rare earth element determinations to low parts per trillion levels. The DRC (dynamic reaction cell) removes interfering Ar species in the plasma and allows trace determinations of several critical elements such as Fe, As, and Se. This machine is also used for Se isotope determinations. 3) A Dionex DX-600 ion chromatograph, used to determine anions and cations in waters, Cl, F, and Br in rocks, in addition to As and Se speciation. 4) Titration station, for alkalinity determinations.
The principal mass spectrometer is a Finnigan MAT 261 equipped with 9 collectors and a secondary electron multiplier. Also available are an updated NBS 12 inch instrument that is used principally for Rb isotope dilution measurements, and a fixed multicollector, donated by Mobil Oil Corp., that is used for studies of Sr in carbonates. The mass spectrometers are supported by Class 100 clean room facilities with sub-boiling acid distillation apparatus, micro- and semi-microbalances, and vessels for pressure decomposition of refractory silicates. Studies focus on using the evolution of Sr, Nd and Pb as indexes of petrogenetic processes, geochronology, environmental Pb, use of Pb as an index of bone mineral resorption, and evolution of marine Sr. A large inventory of spikes allows precise isotopic dilution analyses of elements of geological (U, Th, REE), environmental (Ag, Cd), or metabolic interest (Ca, Cu, Fe, Mg, Zn).

The Remote Sensing Certificate is supported by both the Department of Geosciences and the School of Social Sciences. Faculty involved are Certificate Coordinator Mohamed G. Abdelsalam, Ronald Briggs, Fang Qiu, and Robert Stern.
The American Society for Photogrammetry and Remote Sensing (1997) defined remote sensing as the art, science, and technology of obtaining reliable information about physical objects and the environment, through the process of recording, measuring and interpreting imagery and digital representation of energy patterns derived from non-contact sensor systems.
Remote sensing is a powerful set of software and hardware, computer-based techniques for extraction and presentation of information represented by raster and vector spatial data acquired via non-contact sensors. It provides reliable and cost-effective means of studying the environment for protection, natural resources management and urban planning. Government and non-government organizations continuously seek qualified professionals to use remote sensing for a wide range of applications.
The Graduate Certificate in Remote Sensing is obtained by completing 15 hours of courses. Students must complete the following courses: GEOS 5325 Introduction to Remote Sensing, GISC 6381 Introduction to G. I. S., GEOS 5326 or GISC 7365 Remote Sensing Digital Image Processing, and GEOS 7327 or GISC 7367 Remote Sensing Workshop.
