EON-ROSE and the Canadian Cordillera Array – Building Bridges to Span Earth System Science in Canada

Abstract

EON-ROSE (Earth-System Observing Network - Réseau d’Observation du Système terrestrE) is a new initiative for a pan-Canadian research collaboration to holistically examine Earth systems from the ionosphere into the core. The Canadian Cordillera Array (CC Array) is the pilot phase, and will extend across the Cordillera from the Beaufort Sea to the U.S. border. The vision for EON-ROSE is to install a network of telemetered observatories to monitor solid Earth, environmental and atmospheric processes. EON-ROSE is an inclusive, combined effort of Canadian universities, federal, provincial and territorial government agencies, industry, and international collaborators. Brainstorming sessions and several workshops have been held since May 2016. The first station will be installed at Kluane Lake Research Station in southwestern Yukon during the summer of 2018. The purpose of this report is to provide a framework for continued discussion and development.RÉSUMÉEON-ROSE (Earth-System Observing Network - Réseau d’Observation du Système terrestrE) est une nouvelle initiative de collaboration de recherche pancanadienne visant à étudier de manière holistique les systèmes terrestres, depuis l’ionosphère jusqu’au noyau. Le Réseau canadien de la cordillère (CC Array) en est la phase pilote, laquelle couvrira toute la Cordillère, de la mer de Beaufort jusqu’à la frontière étasunienne. L’objectif d’EON-ROSE est d’installer un réseau d’observatoires télémétriques pour suivre en continu les processusterrestres, environnementaux et atmosphériques. EON-ROSE est un effort combiné et inclusif des universités canadiennes, des organismes gouvernementaux fédéraux, provinciaux et territoriaux, de l’industrie et de collaborateurs internationaux. Des séances de remue-méninges et plusieurs ateliers ont été tenus depuis mai 2016. La première station sera installée à la station de recherche du lac Kluane, dans le sud-ouest du Yukon, au cours de l’été 2018. Le but du présent rapport est de fournir un cadre de discussion et de développement continu.

The Upper Mantle Structure of Northwestern Canada From Teleseismic Body Wave Tomography

“…In particular, coherent high phase velocity anomalies (Ward, 2015) and fast shear wave velocities (Jiang et al, 2018; are well defined north of the Tintina Fault at the Alaska/Yukon border. Important questions remain regarding the nature and the origin of the lithospheric mantle underlying the NCC and past and present geodynamics of the region (e.g., Boggs et al, 2018). The recent deployment of the USArray-TA and other seismic stations across Alaska, USA, and Yukon and Northwest Territories, Canada, now allow for higher-resolution three-dimensional seismic velocity models of upper mantle structure.…”

The future of passive seismic acquisition

“…Hanneke Paulssen (University of Utrecht) reviewed the history of the NARS network and highlighted the revolution these mobile networks produced for broadband passive seismology (Nolet & Vlaar 1982). Fiona Darbyshire (Université du Québec à Montréal) described similar efforts in Canada, starting with the pioneering LITHOPROBE experiment (Rondenay et al 2000), which focused more on active-source seismology, and moving on to the vision of a future network, EON-ROSE, a multi-instrument network across the continent using broadband seismometers, GNSS and magnetospheric sensors (Boggs et al 2018). Corinna Roy (University of Leeds) presented a novel inversion method to better image crustal velocity structure and to improve characterization of small earthquakes in a mining setting.…”
