The oceans play a critical role in the global carbon cycle, serving as a sink for anthropogenic carbon dioxide emissions, and regulating the atmospheric carbon dioxide concentration. My research is focused on understanding the processes controlling air-sea carbon dioxide exchange. I investigate how these processes operated in the past, how they function today, and how they might respond to a future characterized by increased greenhouse gas forcing.

ATOC 1060 - Our Changing Environment: El Nino, Ozone, and Climate
Primary Instructor
-
Fall 2018
Discusses the Earth's climate for nonscience majors, focusing on the role of the atmosphere, oceans, cryosphere and land surface. Describes the water cycle, atmospheric circulations and ocean currents, and how they influence global climate, El Nino and the ozone hole. Discusses human impacts from climate change. Recommended prerequisite: ATOC 1050. Degree credit not granted for this course and GEOL 1060.
ATOC 4200 - Biogeochemical Oceanography
Primary Instructor
-
Spring 2018 / Spring 2019
Provides a large-scale synthesis of the processes impacting ocean biogeochemistry. Transforms theoretical understanding into real-world applications using oceanographic data and models. Topics include: chemical composition, biological nutrient utilization and productivity, air-sea gas exchange, carbonate chemistry, ocean acidification, ocean deoxygenation, iron fertilization, biogeochemical climate feedbacks and more. Recommended prerequisites: one semester of calculus and one semester of chemistry. Same as ATOC 5200.
