Who We Are

picture of Roberta HammeRoberta C. Hamme, Professor
(she/her) My research interests centre around using dissolved gases to understand aspects of the ocean's carbon cycle, especially the biological pump. I am particularly interested in data from sensors from autonomous platforms like profiling Argo floats and moorings, with a focus on oxygen. When not working, I love to spend time with my family, two children and husband, exercise, and enjoy the beauty of Victoria

Hayden Amidon, Graduate Student - PhD
(he/him) My research is using laboratory experiments to refine in-air calibrations for oxygen optodes by investigating the effects of waves and UV exposure on the instruments. This project aims to help create a more reliable and accurate oxygen inventory of the global ocean. I am also interested in broad oceanographic topics such as climate change, carbon drawdown, element cycling, and paleoceanography. Outside the lab I'm often listening to music, biking, or gaming.

(she/her) The focus of my PhD research is investigating oxygen respiration rates below the surface. I perform analysis using biogeochemical Argo-float data to calculate respiration rates at different depths and years.
Lauren Bannerman-Maxwell, Graduate Student - MSc
(she/her)The primary focus of my research is to analyze C-PROOF (Canadian-Pacific Robotic Ocean Observing Facility) glider data from the perspective of a biological oceanographer. The first step in doing so, is calibrating the glider’s in vivo fluorescence sensor using ship-based extracted chlorophyll measurements. I will then use the corrected glider in vivo fluorescence values to better understand phytoplankton biomass within the NE Pacific. In addition to my studies, I am also passionate about Scuba Diving and citizen science programs.

Ocean Gases Lab Alumni

picture of Lynn Wharram Lynn Wharram, Technician
(she/her) I studied chemistry and ocean science at UVic and am interested in researching how the oceans are changing and what is causing those changes. My passion and curiosity for the oceans have led me to a career path that allows me to learn and expand my knowledge on a daily basis and be a volunteer in the community with others who want to learn about and protect our oceans.
Patrick Duke, PhD
(he/him) I am from the traditional territory of the Blackfoot Confederacy (comprising the Siksika, Piikani, and Kainai First Nations) as well as the Tsuut'ina First Nation, and the Stoney Nakoda in Calgary, AB. My PhD focused on estimating air-sea carbon fluxes in the NE Pacific using a machine learning approach. I was part of the larger Canadian Marine Carbon Sink Project with collaborators across the country. I am also a sustainability leader in my community, focused on training people to combat climate change through art, policy, and innovation.

(she/her) My MSc research focused on how nitrogen cycles in the ocean. More specifically, how nitrous oxide - a strong greenhouse gas - is produced through nitrification and denitrification. My work was done using virtual experiments that try to narrow down how we understand and parameterize the mechanisms behind these processes.
Parsa Gooya, MSc
(he/his) I am interested in how oceans regulate climate through the marine carbon sink. I studied how the oceans have responded and are projected to respond to increasing amounts of carbon in the atmosphere and in turn, how that is going to affect the climate. I made use of Earth System Model projections and data/uncertainty analysis.
