Analytical equipment includes a new Dionex DX600 Ion Chromatograph with UV detector, a Perkin-Elmer 5000 Atomic Absorption Spectrophotometer, and a Hach DR/4000 UV-VIS spectrophotometer. Dr. Hibbs also has standard hydrogeological field equipment for student use.
  
  
• Geographical Information Systems - The Center for Spatial Analysis and Remote Sensing (CSARS) has a total of twenty-five Pentium PCs that run Windows NT versions of GIS software with all key extensions, and various types of image processing software. Installed software packages that can be accessed from CSARS PC's through X-Windows include ArcView, Arc/Info, ENVI/IDL, Fortran, C, and JAVA compilers. The Virtual Center for Spatial Analysis and Remote Sensing (VCASRS) is a second distributed computing facility linked with CSARS. It includes numerous workstations for spatial analysis, and instrumentation devoted to remote and close-up sensing of landscapes.

Los Alamos National Laboratory

The Los Alamos National Laboratory (LANL) is well known for its expertise in advanced computing and numerical simulation of physical phenomena. The capabilities of the Los Alamos computers allow very highly resolved simulations to be performed, based on which up-scaling schemes can be designed through sensitivity experiments. The new computer at Los Alamos, built by Silicon Graphics, is capable of 1012 operations per second and is based on 2,048 R10K processors running at a rate of 250 MHz each. Memory consists of 512 Gbytes of RAM and 5 terabytes of local disk. Later generations of this machine will be capable of 10-100 teraflops with correspondingly larger numbers

Research at LANL includes the development of high-resolution computer models of coupled hydrologic systems, with Department of Energy funding at the level of $900K/year for 5 years. The study is designed to provide insight into how the discrete physical components of coupled hydrologic/environmental systems (e.g., atmosphere and land surface) interact nonlinearly and operate at different time and space scales. In particular, the current research emphasizes the importance of inter-domain exchanges of mass and energy, which have not previously been represented with enough detail because adequate computational resources and physical models have been unavailable. The goal is to develop a new generation of modeling tools that can be used to assess, manage, and eventually predict, the evolution of regional catchments. These tools will facilitate the study of a large variety of future environmental security issues ranging from global challenges such as CO2 and water cycles, to local and regional problems such as fresh water supply, agriculture, and flooding.

Research at LANL addresses advances in both the computer and physical sciences, for efficient parallelization (development of a new communicating asynchronous processes alternative to the standard massively parallel computing method), data mining, numerical schemes capable of accurately representing large gradients, gridding methods capable of representing highly variable geologic media (such as those found in groundwater basins), new turbulence schemes to support high-resolution modeling, methods of scaling to assure commensurability of data passed among individual physical components, and upscaling through averaging techniques, scaling laws, and sensitivity analysis.

• Laboratory of Isotope Geochemistry - Using isotopic tools in concert with conceptual and computer flow models, the Laboratory of Isotope Geochemistry conducts research to develop a quantitative understanding of aquifer hydrodynamics. The lab, led by Austin Long, has five full-time staff and receives funding through sample analysis in conjunction with numerous projects. At least seven SAHRA research projects currently utilize this facility at a reduced sample cost. A low level 1220 Quantulus liquid scintillation spectrometer was purchased in 2002 for ³²S, tritium, and radiocarbon analysis through funds from the NSF "Glue Grant" matched by the UA and SAHRA. This dedicated instrument gives SAHRA full-time access to investigate the use of ³²Si as a tracer of long-term recharge rates in semi-arid regions. The Lab's instrumentation includes six additional low-level liquid scintillation spectrometers for radiocarbon and tritium measurements, three isotope ratio mass spectrometers for measurements of the stable isotopes of carbon, hydrogen, oxygen, sulfur and chlorine, an ion chromatograph, and an automated device for detecting d¹⁸O and d²H isotopes in water.
• Noble Gas Laboratory - Beginning in 2003, SAHRA researchers have at-cost, priority access to a new noble gas laboratory for water samples. Housed in the Dept. of Geosciences at the UA, the lab measures noble gas isotopes, which can be used in groundwater analysis to map basin regions in terms of dominant recharge characteristics (because of the variability in noble gas signatures caused by elevation and temperature differences). Additionally, helium isotopes (³He and ⁴He) can be used to calculate water residence times for both the short term (the past several decades) and long term (thousands of years ago to extreme antiquity). These methods are currently available in only a few labs worldwide.
