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. We make our own high precision measurements of oxygen, nitrogen, argon, neon, and krypton. We also use dissolved gas measurements, especially oxygen, from autonomous sensors like profiling Argo floats and moorings.

Lynn Wharram, Technician
(she/her) I am studying 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 lead 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.

(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 is focused on estimating air-sea carbon fluxes in the NE Pacific using a machine learning approach. I am 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.

Simin Kheradmand, Graduate Student - PhD
(she/her) The focus of my PhD research is investigating the biological carbon pump (BCP) by measuring oxygen concentration in ocean. I perform analysis over biogeochemical Argo-float and gliders data to correct historical oxygen measurements and making physical model of the Net Community Production (NCP) rate.

(he/his) I am interested in how oceans regulate climate through the marine carbon sink. I study 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 make use of Earth System Model projections and do data/uncertainty analysis.
Rebecca Pierce, Graduate Student - MSc
(she/her) I research how nitrogen cycles in the ocean. More specifically, how nitrous oxide - a strong greenhouse gas - is produced through nitrification and denitrification. My work is done using virtual experiments that try to narrow down how we understand and parameterize the mechanisms behind these processes.
