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.

The 24 applications provided in the latest PASSOFT installation include the following.

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.

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.
