Field Equipment

<- Back to Rio Grande Research Center

There is no shortage of gear required for river and land-based research trips. The Rio Grande Research Center is well equipped for multi-day, back-country expeditions. The river fleet includes 20 canoes, 4 inflatable rafts, Personal Flotation Devices (PFDs) for up to 30 participants, a full camp kitchen, portable shade structures, coolers and river-proof containers, dry bags and the heavy-duty 4WD vehicles and trailers required to deliver expeditions, equipment and researchers into the field.




Spectra Precision Focus 4 Total Station:  The Focus 4 Total Station Provides quick and accurate measurements of horizontal distance, vertical distance, horizontal and vertical angles, difference in elevations of two observed points and all three coordinates of the observed points.




YSI 556MPS Multi Probe:  The YSI 556MPS is used for evaluating water quality by simultaneously measuring dissolved oxygen, pH, conductivity, temperature, and ORP as well as Dissolved Oxygen, conductivity, and temperature.




SonTek FlowTracker Handheld-ADV:  The FlowTracker ADV (Acoustic Doppler Velocimeter) features an automatic discharge computation and simplifies discharge measurements by giving built-in data quality checks to assist the user in providing a dependable and accurate evaluation of river discharge.




Trimble R6 Base and Rover RTK (Real-Time Kinematic) Paired with Trimble TSC3 controller:  A Trimble R6 GPS receiver setup is used utilizing a base station and rover allowing real time kinematic GPS (Global Positioning System)/GNSS (Global Navigation Satellite Systems) surveying.




Trimble Juno Series Educator:  The Trimble Juno Series is Rugged, lightweight and compact GPS handheld with 5MP camera, 2-5 meter GPS receiver, with built in Wi-Fi and Bluetooth connectivity as well as a Windows 6.5 Professional operating system. 




Marsh McBirney Flo-Mate:  The Flo-Mate is a lightweight, portable electromagnetic flowmeter that provides instantaneous readout of flow stream velocity, river velocity.




Sequoia LISST Portable:  The LISST-Portable is a battery powered portable laser diffraction particle size analyzer that uses small-angle laser scattering principles to measure particle size, distribution, and particle volume of a water sample.

Teledyne RiverRay:   The RiverRay ADCP or Acoustic Doppler Current Profiler allows safe and fast measurements of flow discharge, velocities, depth, boat speed, and distance of a cross section of river. This information is collecting in real-time coupled with a GPS receiver it allows the user to have a much more complete river profile.




Teledyne StreamPro:   A smaller version of the ADCP this unit allows for measurements of flow discharge, velocities, depth, boat speed, and distance of a cross section of river. However this unit can be used in very low water conditions with low flow in which other types of equipment would have difficulties. Being much smaller and lighter than the RiverRay makes it perfect for the conditions often found on long river trips.

JOEL JSM-6010LA Scanning Electron Microscope (SEM: The SEM is used to obtain microscopic images of samples and to collect information regarding the chemistry of the samples using the attached Energy Dispersive X-Ray spectrometer.
