Pegasus Datalogger

The Pegasus is a 3 channel high-resolution data logger. It is very low power and easily configurable via a handheld device. The Pegasus is lightweight and small in form factor. The Pegasus has 32 gigabytes of internal recording space, and is downloaded via free software through USB. It supplies MiniSEED data along with StationXML to smoothly allow data archival. It also has built-in sensor controls, automatic mass re-centering, and calibration functions. The Pegasus is currently supplied as a set with a Trillium Compact sensor for a small station footprint and ease of installation.

Magseis Fairfield ZLand 3C Node - 3-Channel All in One, Sensor and Datalogger

The FairfieldNodal ZLand 3C is a compact all-in-one 3-channel sensor & datalogger with onboard GPS timing, and a self contained power supply. Originally designed for use in large N industry deployments, it has been adopted by the academic community as a useful sensor for both active and short-term passive deployments.

Unlike other sensors & dataloggers at PASSCAL, use of the ZLand 3C requires a deployment plan to be filed in advance with PASSCAL for handheld unit pre-programming.  Likewise, the units must be sent back to PASSCAL for data offload.

IRIS/PASSCAL profiled in the Socorro Newspaper

 

The August 16th, 2018 edition of Socorro's El Defensor Chieftain featured a cover story describing the IRIS/PASSCAL Instrument Center located at New Mexico Tech. Reporter John Larson's piece says "Tucked away on a hilltop in the backyard of Tech’s campus is the Incorporated Research Institutions for Seismology Portable Array Seismic Studies of the Continental Lithosphere Instrument Center – IRIS/PASSCAL for short – the largest facility of its kind in the world.

All-In-One Systems

All-In-One systems combine seismic sensors with their dataloggers in a single, easily-deployed unit. Because these units do not require numerous cables to connect a sensor to its datalogger, they avoid many serious problems associated with cables, such as incorrect connector types, broken and chewed wires, or damaged pins. They are also much easier to deploy than conventional sensor/datalogger combinations. Their use can dramatically cut down on both station installation times and the number of required personnel. Their smaller size can also be very beneficial for deployments using volume-limited transportation methods, such as sea vessels.

Because Nodes and SmartSolos both utilize lithium batteries that operate above the 100Wh threshold, shipping of more than 2 units produced by either vendor will require special handling, including: packing, marking and documentation. Special handling, if needed, will require the assistance of a certified dangerous goods shipper.

GEOICE

The Geophysical Earth Observatory for Ice-Covered Environments (GEOICE) project was a NSF collaborative Major Research Instrumentation (MRI) program that expanded the PASSCAL Polar group’s observational capabilities and logistical efficiencies. GEOICE developed a rapidly deployable, dense footprint seismic observatory system for operation in ice-covered areas. The GEOICE project was a collaborative effort between Central Washington University (CWU), Incorporated Research Institutions for Seismology (IRIS) and the Portable Array Seismic Studies of the Continental Lithosphere (PASSCAL) Instrument Center at the New Mexico Institute of Mining and Technology.

Smart Solo IGU-16HR 3C

The Smart Solo IGU-16HR 3C is a compact all-in-one 3-channel sensor & datalogger with onboard GPS timing, and a self-contained power supply. Similar to the FairfieldNodal ZLand 3C, it has been adopted by the academic community as a useful sensor for both active and short-term passive experiments.

The units require a pre-deployment plan to be filled out with the sample rate, gain, and minimum or linear phase specified. The units must be sent back to PASSCAL for data offload, unless the portable harvester system is requested for the experiment.
