Research Interests:

Research Emphasis:

Yager's interdisciplinary research approach includes oceanography, marine microbial ecology and biogeochemistry. Her work concentrates on the feedbacks between climate and marine ecosystems, and includes both fieldwork and modeling. Recent projects include investigating the effects of melting ice sheets on Arctic and Antarctic coastal productivity, and carbon sequestration by microbial communities in the Amazon River plume.
