RESEARCH

FIELD EXPEDITIONS

Northwest Passage 2021

Our group was funded by the Natural Sciences and Engineering Research Council of Canada for Ship Time to sample the Northwest Passage this year. The research mission was dubbed RADCARBBS (Radiocarbon Distributions and Carbon Cycling between Baffin Bay and the Beaufort Sea).

BAFFIN BAY 2019

Our group participated on a research cruise to Baffin Bay in the summer of 2019. Our work was focused on understanding both the ventillation age of Baffin Bay, and using 14C as a tracer for organic matter cycling in this rapidly changing Arctic region.

INSTRUMENTS, FACILITIES AND PARTNERS

Walker lab @ UOTTAWA

We are currently working on building out core lab instrumentation in our temporary home in the Center for Advanced Research in Environmental Genomics (CAREG). Although it won't be our home for long, it has been a nice place to get field prep. done and comes with a pretty sweet view of Parliment Hill, and you can't beat the proximity to the light rail station and Rideau Canal.

AEL-AMS lab @ UOTTAWA

Professor Walker is a member of the André E. Lalonde AMS national facility Management Team and PI of the facility's 2023 Major Scientific Initiatives proposal. Our group works closely with the AEL-AMS lab, Canada's National Center for Accelerator Mass Spectrometry, and the Radiocarbon team at uOttawa. The facility houses two AMS systems: a 3 million volt HVE AMS and a new 200 kilovolt MICADAS dedicated to radiocarbon dating.

NMR @ UOTTAWA

Our group is excited to be working with the NMR facility at uOttawa in unraveling the mysteries of DOM composition in the ocean. We are very thankful for the expertise and training we have received from Facility manager Dr. Glenn Facey - who also has a wonderfully resourceful NMR blog!
