Our research backgrounds are climate dynamics and oceanography, which are applying to examine the interactions of climate variability with biogeochemistry and plankton dynamics. Our research topics have been diverse and include 1) an assessment of satellite chlorophyll observations to characterize modes of variability and assess opportunities for empirical prediction, 2) multi-model analysis of Arctic biogeochemistry and chlorophyll-climate feedback under climate warming, 3) mechanisms underlying ENSO-biogeochemistry-chlorophyll evolution in GFDL’s Earth system models, and 4) the role of modeled dynamic terrestrial dust variability on ocean biogeochemistry. Our current research topic aims to understand how much of the interannual variance in fisheries production is explained by climate variability at regional and global scales, how predictable are ecosystem changes, and what are the mechanisms involved.
