Want a  ‘behind the scenes’ look at Nanometrics?


Join us for our IUGG Field Trip! Only 6 spots left!

 

Date: July 11
Cost: Free. Includes transportation from Montreal to Ottawa and back, lunch and light refreshments
 
Nanometrics Seismic Monitoring Solutions invites you to an exclusive open doors visit to their headquarters near Ottawa, Ontario. This excursion to Kanata, (aka “Silicon Valley of the North”), will provide you with a unique opportunity to tour their manufacturing facilities. The tour will also include hands-on product demonstrations and seminars on our latest products, research and science developments.

 

Come to IUGG in Montreal and visit our booth # 318 to speak to Tim Parker, our New Business Development Manager, and Nicholas Pelyk, our Sales Manager USA & Canada, to learn more about our new seismic monitoring products and solutions.

Initial Test Results for the Trillium Slim Borehole 120 Seismometer
We present initial test results for this instrument in small and large diameter cased holes, direct burial, and side-by-side pier testing. 
Date: July 14
Time: 5:30-5:45pm
Track: S01

 

Abstract

The new Trillium Slim Borehole 120 seismometer is a 104 mm diameter instrument with Trillium 120QA/PH class performance having significantly improved SWaP (size, weight and power). It is designed for smaller holes down to 115 mm diameter, in shallow or deep deployment, using a simple passive holelock or sand installation.  The small diameter permits deployment in existing small boreholes, and facilitates construction of new lower cost boreholes, minimizing disturbance of the surrounding rock and improving instrument coupling.

 

We present initial test results for this instrument in small and large diameter cased holes, direct burial, and side-by-side pier testing.  

 

High performance with simpler logistics makes the Trillium Slim Borehole well suited for many applications, including new higher-density arrays for full waveform analysis, early warning, and detection of earthquake gravity signals. 

 

New Approaches to Broadband Seismic Array Deployments for Rolling Arrays and Enhanced Longterm Backbone Infrastructure

Date: July 14
Time: 3:00-4:30pm
Track: S10
Poster Session

 

Abstract

Large temporary broadband seismic arrays such as the Earthscope Transportable Array initially depended on sensors that needed pier type deployments and large temporary vaults. As the array moved across the USA and on to Alaska there was a switch to new posthole type sensors in shallow cased holes as a practical and better approach. A measurable improvement in performance was observed related to deeper and more stable installations along with a quieter station environment. These same posthole type sensors with robust environmental specifications were also used in direct burial deployments with good success and comparable station noise metrics. New posthole type lower power sensors are available that are capable of similar performance based on very simple direct bury deployment techniques. This development should enable these types of rolling arrays to be deployed very quickly and with much less cost with performance similar to the more expensive shallow cased hole technique used in Alaska for Transportable array. The direct burial technique is being used in many new broadband array experiments. We propose reducing the power and infrastructure required for these research stations by using new lower power digitizers and sensors along with limiting telemetry to simple state of health enabling dense arrays to be deployed in these temporary arrays and preplanning backbone stations so investment in permanent stations follows deeper cased hole best practices.

 

A Next Generation Compact High Resolution and Low Power Multi–Sensor Digitizer for Dense Autonomous Arrays
Date: July 14
Time: 3:00-4:30pm
Track: S10
Poster Session

 

Abstract

The seismic research community has been looking for solutions and new equipment for temporary array studies in broadband and mixed sensor deployments. Researchers needing high resolution broadband waveforms have lacked station density because of broadband system availability, capital costs, logistical costs, time to deploy stations and the complexity of the systems.

Nanometrics is addressing this need with the introduction of the Pegasus digital recorder and supporting ecosystem which is designed to provide high resolution recording in temporary networks and remote environments. This digitizer is a complementary recording system with posthole type broadband sensors and direct burial techniques.

The digitizer power is less than 200mW for three channels. It is very small (<1.25 liters), lightweight (<.5 kg) and IP68 rated for immersion with a robust enclosure for autonomous operations in all terrestrial environments. Installation and servicing is simplified by an intuitive user interface, applications and digitizer features. This ecosystem makes reaping the data very fast, verified and reliable while field station operational review is completed quickly and with certainty. Coupled with a Nanometrics directly buriable broadband sensor the total station power for a state of the art Trillium broadband station is less than .5W. An optional fourth channel can be used for a geophysical high resolution sensor such as an infrasound device, tilt meter or absolute pressure sensor. Metadata is FDSN compliant and created on thedigitizer and the waveforms are available in MiniSEED data format along with comprehensive project/station audit information.
