Biological Oceanography

biological oceanography

Biological oceanography is the study of processes affecting the abundance, production, and variability of life in the oceans. At UGA we study some of the smallest organisms in the ocean such as bacteria, phytoplankton, and zooplankton. Although they are small, these organisms collectively have a global impact and affect the productivity of the oceans and how elements such as carbon are utilized and transformed. We work to unravel the factors controlling the growth of their populations, when and where they bloom in the oceans, and their interactions by using field observations, laboratory experiments, and computer modeling. 


Research in the Bik Lab is intensely interdisciplinary, using high-throughput sequencing and diverse –Omics approaches to explore broad patterns in marine microbes (biodiversity and phylogeography, functional roles for microbial taxa, and the relationship between species and environmental parameters), with an emphasis on microbial eukaryotes in…

My research involves the use of mathematical and computer modeling to understand how different marine systems function and how they might change under changing environmental and climate conditions. For me, a marine system can mean many things; a the biological and chemical transformations of a single particle of detrital material settling…

-Influence of physical oceanography and ecological interactions on the abundance and distribution of zooplankton and early stage fishes

-Application of imaging technology and computational approaches to answer ecological questions

-Diel vertical migrations of zooplankton and behavioral responses to oceanographic features (e.g.,…

Research Emphasis:

Yager's interdisciplinary research approach includes oceanography, marine microbial ecology and biogeochemistry. Her work concentrates on the interactions between climate and marine ecosystems, and includes both fieldwork and modeling. Recent projects include investigating the effects of melting ice sheets on Arctic…
