WHOI research projects awarded $5.2 million to support marine microbial research
Date:12/27/2012

se grants will allow WHOI investigators to look at the molecular basis for the much more complex processes that they have hypothesized are at play in the sea.

These awards target advancing understanding at inter-disciplinary interfaces in microbial oceanography by supporting the development of sophisticated technologies and methods and by testing the newly developed approaches in the field. The funded projects at WHOI include:

  • Investigating Dissolved Organic Matter in the Microbial Loop WHOI chemist Dan Repeta with Ed DeLong at MIT.
    To develop laboratory and field-based experimental systems for characterizing the roles of microbial physiology, ecology and biogeochemistry in the cycling of dissolved organic matter in the nutrient-poor ocean.

  • Identification and Quantification of New Biomarkers for Key Microbial Species WHOI chemist Elizabeth Kujawinski.
    To develop new protocols to detect the products of microbial metabolism in seawater to understand the influence of marine microbial communities and their activities on the chemical composition of their surroundings. The new procedures will enable researchers to quantify the abundance of these molecules that serve as the currency of nutrient flow among the studied microbes.

  • Infochemical Control of Microbial Carbon and Nutrient Cycling in the North Atlantic WHOI chemists Ben Van Mooy and Tracy Mincer, and WHOI biologist Matt Johnson, with Kay Bidle at Rutgers and Assaf Vardi at the Weizmann Institute of Science in Israel.
    To investigate how certain molecules or "infochemicals" that microbes use to communicate with one another influence microbial interactions and nutrient cycling in the North Atlantic Ocean. The project has the potential to create a new view of the sea where infochemical signaling governs the inter- and intra-domain microbial interactions that influence the biogeochemical fluxes of carbon and nutrients.
