Climate & the Environment

The Institute for Geophysics shares data from a range of aerogephysical missions flown over Antarctica.

UTIG has developed, maintained, and operated a suite of aerogeophysical instrumentation since the early 1990s with continual improvements since inception. The suite was installed aboard a Dehavilland DHC-6 ("Twin Otter") up to 2005 and aboard a Basler BT-67 (a version of DC-3T -- a Douglas DC-3 refitted with turboprop engines) since 2008. The current instruments are: High Capability Radar Sounder (HiCARS); Multibeam, Scanning Photon Counting Lidar; Cesium Vapor Magnetometer; Gravimeter; Dual-frequency, carrier-phase Global Navigation Satellite Systems (GNSS); Laser Altimeter; Two GPS-aided Inertial Measurement Units; Three-Axis Fluxgate Magnetometer; System Control, Data Acquisition, and Real-time QC and Monitoring functions.

Public facilities include core examination layout rooms and processing rooms for slabbing core. Other services are available upon request.

The Houston Research Center (HRC), is located on the west side of Houston, Texas, six miles north of I-10 and two miles south of U.S. Highway 290. This state-of-the-art climate-controlled facility is equipped to permanently store and curate over 900,000 boxes of geologic core and cuttings. The Houston, Austin, and Midland core facilities have combined holdings of nearly 2 million boxes of geologic material. In addition to the climate-controlled core and cuttings warehouse, the HRC complex has offices, laboratories, and a well-lit core layout room available for visiting scientists. There are also two conference rooms to accommodate guests attending short courses and seminars. Other services are available upon request. Nominal fees are charged to rent table space and to view core. The HRC has space dedicated for storing samples and cores acquired by NSF-funded research. The HRC curates this material and facilitates continued access to the material by researchers.

Water is injected below the "ice" at varying rates to observe the effects of discharge pulses on the channel geometry and surface motion of the "ice." Changes in discharge are designed to mimic a typical diurnal discharge pattern observed on alpine glaciers.

The Isotope Clean Lab is a 600 square foot clean chemistry lab with seven Class-100 workspaces for preparation of rock, mineral, soil, plant and water samples for chemical and isotopic analysis under low-contamination conditions.

Within the Department of Geological Sciences there are three clean-room laboratories supplied with HEPA-filtered class 100 air where sample preparation and ion-exchange chromatography for isotopic analysis may be done under ultra-clean conditions, making possible very low analytical blanks (e.g., < 1 pg Pb for U-Pb geochronology, and <10 pg Sr). There are also two other laboratories with HEPA-filtered work stations where sample preparation and ion-exchange chromatography are performed. These labs are affiliated with the Mineral Separation Facility (see description).

The MC-ICP-MS facility is centered around a Nu Instruments Nu Plasma 3D MC-ICP-MS featuring 6 Daly detectors for simultaneous measurement of multiple low abundance isotopes, in addition to 16 stationary Faraday cups, enhanced abundance transfer sensitivity optics (EATO) and dry scroll pumps. It is installed in a positively pressured, hepa-filtered, clean lab and supported by two clean chemistry labs for dissolution of samples and isolation of specific elements for isotope analyses. Samples may be introduced as a solution using the DSN100 desolvating nebulizer or as a solid using an Elemental Scientific Lasers (ESL) NWR193 laser. The facility regularly analyzes Li, Pb, Hf isotopes, parent isotopes Lu, Sm, and Rb for isotope dilution analyses (Sr and Nd measured by TIMS), and Lu-Hf in zircon by laser ablation. We are developing methods for multi-Daly measurement of low abundance isotopes for U isotope measurements, U-Th dating and laser ablation Pb and Li isotope measurements.

NPL, part of the Texas Natural Science Center, was created in 1999 as an answer to the increasing conservation and curation issues developing with the huge increase in collection size. Collections placed in the care of TNSC mainly were derived from research at the BEG, the UTDGS and the Museum (TMM) itself. Other material came from orphaned collections within Texas. Numerous other collections have been contributed as donations. Although an exact count has never been made, the collection is estimated to contain about 4 million.

Major instrumentation includes: (1) Gas chromatograph-single quadrupole mass spectrometer (GC-IRMS) for quantification and identification of organic compounds, and (2) HPLC-signgle quadrupole mass spectrometer (HPLC-MS) equipped with intelligent fraction collection for identification, quantification and isolation of high molecular weight compounds.

The Quadrupole ICP-MS laboratory (with laser ablation) is used for elemental determinations in a wide range of liquid (e.g., natural waters, dissolved sediments/rocks, digested biomass) and solid (e.g., rocks, minerals, glasses) samples. The ICP-MS instrument is an Agilent 7500ce, capable of measuring trace element concentrations in solution over a nine-order linear dynamic range, from ppt to 100s of ppm. Sample introduction systems include a Micromist concentric nebulizer with a Peltier-cooled spray chamber for aspirating solutions, and a New-Wave UP¬193-FX 193 nm excimer laser ablation system for micro-sampling of solids. Sub-ppm detection limits are obtained routinely by laser ablation. The Agilent 7500ce is equipped with a collision/reaction cell, allowing for quantification of environmentally important matrix/plasma-sensitive elements such as As, Se, and Fe. The instrument is housed in a positive-pressure HEPA-filtered laboratory equipped with a weighing station, laminar flow bench, and Type 1 (18.2 M?) ultrapure water station.

The Vertebrate Paleontology Laboratory (VPL) is known worldwide as a major repository for unique scientific collections from the American Southwest. VPL was founded in 1948 by John A. Wilson, Emeritus Professor of Geology at The University of Texas at Austin. Today, VPL is the principal repository for vertebrate fossils collected from state and federal lands in Texas and contiguous areas, as well as for specimens collected elsewhere using state and federal funds. The fossil vertebrate holdings of VPL rank among the seven largest in North America.

The primary research collections of the library presently include more than 100,000 book and journal volumes and 46,000 geologic maps, among them the publications of the U.S. Geological Survey, most state geological surveys, and those of many foreign countries. Regional emphasis of the collection is on the Southwestern United States, Texas, and Mexico. The Institute and Bureau also have extensive libraries related to their specific research areas.

We view the earth system in a holistic way, linking the atmosphere, ocean, biosphere, cryosphere, and solid earth as an integrated system. We use powerful methodologies such as satellite remote sensing and supercomputing simulations which are now profoundly changing research in earth system sciences. We place a strong emphasis on the societal impact of the research in earth system sciences.

The mission of the Vertebrate Paleontology Laboratory is three-fold, involving research, conservation, and education pertaining to the history of vertebrates. In particular, VPL focuses on the history of vertebrates in Texas and adjacent regions, but much broader studies are also conducted to establish a national and global context for Texas vertebrate history.

CFSES is one of only two centers out of 46 EFRCs with focus on subsurface energy. Our goal is a scientific understanding of the physical, chemical, and biological subsurface processes from the very small scale to the very large scale so that we can predict the behavior of CO2 and other byproducts of the energy production that may need to be stored in the subsurface. At this aim, we need to integrate and expand our knowledge of subsurface phenomena across scientific disciplines using both experimental and modeling methodologies to better understand and quantify the behavior at conditions far from equilibrium. The unique aspect of our research is the approach of the uncertainty and of the complexity of the fluids in the geologic media from the molecular scale to the basin scale and their integration in computational tools to better predict the long term behavior of subsurface energy byproduct storage.
