Deploying a Tripod

The department maintains state-of-the-art equipment for conducting high quality field and laboratory research.  Major field equipment includes:

  • Laser In-Situ Scattering and Transmissionmetry (LISST);
  • sea-bed hydraulic flume;
  • a meteorological station with a precipitation collector for low-level organic contaminants;
  • high-volume air samplers;
  • a rotating drum surface microlayer sampler;
  • and bottom boundary layer instrumental tetrapod systems for measuring bed stress, wave and currents, sediment resuspension, and bed level changes.

A variety of instrumentation including:

    Deployment at Sea
  • tide gauges,
  • current meters,
  • conductivity-temperature-depth (CTD) profilers,
  • fluorometers,
  • dissolved oxygen (DO) meters,
  • fathometers,
  • dual-frequency side-scan sonars,
  • variable frequency sub-bottom profiling systems,
  • directional wave gauges,
  • turbidity sensors,
  • acoustic doppler current profilers (ADCP),
  • Kasten and box corers,
  • Microwave and GPS navigation systems are maintained by the department for accurate positioning of research vessels.

The department houses extensive laboratory instrumentation, including:

  • Europa isotope ratio mass spectrometer with ANCA prep unit and dual inlet
  • Alpkem flow Solution 4 Autoanalyzer
  • Shimadzu TOC-5000 Carbon analyzer
  • Antek NOx analyzer
  • microwave-assisted solvent extraction system;
  • large-capacity, refrigerated, programmable centrifuge;
  • ultra-cold (-80 deg C) freezers;
  • Fisons EA1108 CHNS-O analyzer;
  • UV/Vis spectrophotometer;
  • gas chromatographs with flame ionization and electron capture detectors;
  • two quadrupole mass spectrometers;
  • Inductively Coupled Plasma Atomic Emission Spectrophotometer (ICP/AES);
  • EDS system with full SEM imaging capabilities;
  • Powder X-ray Diffractometer;
  • Nitrogen Adsorption Surface Area and Porosity Analyzer;
  • CHNSO elemental analyzer;
  • high performance liquid chromatograph with UV absorbance and liquid
  • scintillation detectors;
  • two laboratory flumes (recirculating and annular);
  • five intrinsic germanium gamma spectrometers;
  • eight channel alpha spectroscopy system;
  • X-ray radiography unit;
  • sedigraph automatic particle analyzer;
  • rapid sediment analyzer.

Computer facilities range from laptop units for field use to work stations supporting LANs (local area networks) to the institute-wide network.  Computer users have ready access to external networks. Pentium-PC, UNIX and MacIntosh systems are supported by the Institute's computer center. Also, the numerical modeling group is supported by a multi-processor Dec/Compaq/HP ES40.
