Thwaites Eastern Ice Shelf,
West Antarctica
Nov-Feb, 2022/23
Glaciology | Geophysics | Ice-Penetrating Radar | Passive Seismics
Three-month field expedition to Thwaites Eastern Ice Shelf, West Antarctica with Principal Invesitgator Dr. Erin Pettit (Oregon State University), a team of 5 scientists, 1 mountain guide, and 1 filmmaker. As we aim to understand the processes behind this rapidly changing glacier system, we conducted Ice-Penetrating Radar surveys, deployed an array of passive seismometers around five parallel fractures, sampled two 5-meter firn cores, conducted districuted acoustic sensing (DAS) surveys across a basal channel, and raised a weather and GPS tower (named "BOB"). Follow BOB on twitter as we hope it will record the collapse of the ice shelf!

Xeitl Sít’ (LeConte Glacier), SE Alaska
June, 2024
Glaciology | Oceanography | Remote Sensing
One-week research cruise (R/V Steadfast) into LeConte Fjord near Petersburg, Alaska. The goal of this project is to measure melt rates at the tidewater glacier's terminus and understand the physics of the boundary layer between the ocean and the glacier ice. To do so, the team designed remote control boats and a novel "meltstake" that drills itself into the face of the glacier. I helped conduct drone-based Structure-from-Motion photogrammetry surveys of the glacier and icebergs, deploy hydrophones on the meltstake, and deploy timelapse cameras.

Tweedsmuir Glacier,
British Columbia
July, 2021
Glaciology | Geophysics | Ice-Penetrating Radar
One-week field expedition to Tweedsmuir Glacier with Dr. Dan Shugar (University of Calgary) and Dr. Gwenn Flowers (SFU), studying paleo-changes of the Alsek River system at Turnback Canyon. We conducted Ice-Penetrating Radar surveys across the glacier and sampled paleosols in the Little Ice Age Moraines at Tweedsmuir's terminus.

Tundra Ecology | Arctic Systems | Phenological Monitoring
Two-month summer field assistantship with Dr. Greg Henry (UBC), studying phenological effects of the warming climate on Arctic plants. Based out of an RCMP base that was abandoned in the 1950s at 79 degrees North, this project has been ongoing since the mid 1980s and provides one of the longest time series of climate change across the High Arctic. This experience changed my life!
