Escaping the pandemic – my experience as an exploration geologist in Yukon

If you had the chance to escape from the ongoing pandemic to a remote exploration geology camp in northern Canada, 150km from the closest town and only accessible by helicopter, would you take it?

I came to Cambridge to start my PhD in January 2020 and, although I was warmly welcomed, things were at first pretty uneventful. However, this changed dramatically with the sudden onset of COVID-19. I chose to return home to Canada where I continued to work on what I still hope to be a lab-based PhD. However, there are, of course, limitations to research from a bedroom 5000km from Cambridge!

Research in Lockdown: Fieldwork Disrupted

My PhD concerns a longstanding question—how do valuable metals move through volcanic systems? Since starting my PhD in September 2018, I’ve been looking forward to testing my hypotheses on this topic in the field, on a six-week expedition called the Metals in Magmas field campaign. Like many Earth scientists, I spent months planning the project’s logistical and technical details. But, two weeks before the fieldwork was set to begin, the outbreak of the current global pandemic stopped the project in its tracks. My plans are now on hold and my PhD can’t continue as originally billed. In this blog post, I hope to share my perspective on the impact of COVID-19 on my PhD research.

Imaging of North-Sulawesi subduction in the Celebes Sea

How does subduction start? The answer to this question remains enigmatic and controversial. The process of subduction, which drives global plate tectonics and helps to shape the Earth as we know it, began as early as 4.1 Ga, but how the first subduction zone initiated remains unknown. Some have argued that the plate tectonic cycle was kick-started by spontaneous subduction at passive continental margins, yet such a phenomenon has thus far not been observed in a modern plate tectonic setting. Consequently, scientists have a very limited understanding of what mechanisms may initiate spontaneous subduction.
