Successful deployment of OBS for the ELVES project!

Shoutout to Taylor and Quan who participated in the successful deployment of 20 broadband OBS stations offshore Wellington, New Zealand, to study the Hikurangi subduction zone! You can find the info on the project here. Taylor also wrote several blog pieces that detail the life and science aboard the R/V Tangaroa during the deployment: Day 1: Off to a rocky start Day 2: Getting out sea legs Day 3: Overcoming obstacles Days 4-5: Re-route to re-survey Photo credits: Taylor Tracey-Kyryliuk

Earthquakes and Locking inVEstigation of Subduction - ELVES

Next week our team of PIs, techs and students is heading to Wellington, New Zealand, to board the RV Tangaroa and deploy a fleet of 20 broadband ocean-bottom stations from the NFSI facility to study the locked zone of the Hikurangi subduction zone. Media stories and vlogs/blogs will follow soon! This project is focused on studying the seismicity and seismic velocity structure in the locked zone of the Hikurangi margin that is thought to produce large megathrust earthquakes and tsunamis.

Congratulations!

Many congratulations are in order for current and former members of the UOgeophysics group: Morgan McLellan successfully defended her thesis entitled “Uncovering the physical controls of slow slip along Cascadia and other global active tectonic margins” in January 2023. Following her PhD, Morgan found employment as a Data Analyst at Statistics Canada. Taylor Tracey Kyryliuk was awarded the prestigious NSERC CGS-D scholarship in May 2023. Hao Mai successfully defended his thesis entitled “Developing deep learning tools in earthquake detection and phase picking” in August 2023.

Congratulations!

Congratulations are in order for two recent UOgeophysics graduates! Stephen Mosher successfully defended his thesis entitled “Neural Network Applications in Seismology” on 14 May, 2021. Following his PhD, Stephen worked at Ocean Networks Canada and is now Acoustical Consultant at State of the Art Acoustik Inc. Jeremy Gosselin successfully defended his thesis entitled “Passive seismic imaging of lithosphere structure at active tectonic margins in Canada and New Zealand” on 17 November, 2021.

Hikurangi project funded

We are happy to announce that our proposal for the study of the southern Hikurangi subduction zone has been fully supported. This project will involve deploying a fleet of 20 broadband OBS from the NFSI during one year to study the seismicity and seismic velocity structure in the locked zone of the Hikurangi margin that is thought to produce large megathrust earthquakes. The project is a collaboration between the University of Ottawa (Pascal Audet), Dalhousie University (Mladen Nedimovic), Victoria University of Wellington (Martha Savage) and GNS Science (Laura Wallace, Emily Warren-Smith, Katie Jacobs).
