New Journal Article | February 2022

A new geological map of the Lau Basin (SW Pacific Ocean) reveals crustal growth processes in arc-backarc systems”, research led by Meg Stewart at Mount Royal University, was published online at GSA’s open-access journal Geosphere. It discusses the development of a new 1:1,000,000 lithostratigraphic map of the Lau Basin, which is a type-example of an active back-arc basin, located in the SW Pacific Ocean. The map was constructed using remote predicitve mapping techniques and provides a new way to quantify the amount and distribution of different types of crust in the oceans. It also helps to better understand how active back-arc basins form and evolve over time.

Accepted Article | May 2021

Geologic and Structural Evolution of the NE Lau Basin, Tonga: Morphotectonic Analysis and Classification of Structures using Shallow Seismicity“, research led by Melissa Anderson at the University of Toronto, was recently accepted for publication at the open access journal Frontiers in Earth Science. This research incorporates remote predictive mapping and morphotectonic analysis to better understand how subduction-transform motion influences the structural and magmatic evolution of the northeast Lau back-arc basin.

New paper | April 2020

Our paper, linking seafloor structures mapped in the Lau Basin to shallow seismic events, was recently accepted at the journal Geochemistry, Geophysics, Geosystems. We digitised over 4000 seafloor lineaments and compared them to the nodal planes of shallow CMTs in the region. We used this new data set to classify new plate boundary segments, where possible. This study highlights that back-arc basins stress regimes are highly variable and are not exclusively extensional. Check out the paper here.

New Position

This week I started at the University of Ottawa as a Research Associate. I will be working on modern oceans and how they relate to ore bearing provinces in Canada. If you would like to learn more about the project click here!

Conference Abstract Accepted | ISC 2018 – Quebec

Last week my abstract was accepted for an oral presentation at the 20th International Sedimentological Congress this August in Quebec city. The title of the talk will be “What did India collide with in the Early Eocene? Characterizing the sediment source of the Chulung La Formation, Ladakh, NW India“. My co-authors are Jonathan Aitchison (UQ), Luke Milan (UNE) and Rosanna Murphy (UNE). I will also co-convene an open session on sedimentary processes at the conference.

AGU Fall Meeting 2017

Last week I flew down to New Orleans to attend and present at the AGU Fall Meeting. It was a great conference, I got to meet up with my old shipmates from Expedition 344 and 354 and other colleagues and friends from around the world. I attended many great talks and I have a long list of new research ideas to work on. The post-conference part wasn’t too bad either!



New paper | Kutterolf et al., (accepted)

A second paper from the IODP Expedition 352 project I was working on over the last year was accepted at Geochemistry, Geophysics, Geosystems. It focuses on the tephra history of the IBM forearc sediments. Congrats to all involved!

ANU Press just released a new book entitled Australian and New Zealand achievements in the first phase of IODP Scientific Ocean Drilling (2008-2013) which chronicles the scientific accomplishments of the first phase of IODP. It specifically recounts how Australian and New Zealand scientists have contributed to the program. I was invited to contribute to this book and gave a personal account of my time on the ship. If you would like to read it, the ebook can be downloaded for free by clicking on the title above.
