Upper ocean biogeochemistry |
Molecular microbial oceanography
Project Manager/Lead Scientist: Ed DeLong
Microbes critically impact and mediate nearly every major
biogeochemical cycle on Earth. Microbial interactions that occur on the
scale of microns can regulate global ocean processes on planetary wide
scales. Although general procedures to detect, identify and functionally
characterize and quantify microbial species and their activities in the
marine environment are improving, they are still relatively crude, and
lack resolution and sensitivity.
Ed DeLong’s lab will investigate microbes that contain a novel type
of CO2-fixing enzyme, the nature and diversity of novel
bacteriochlorophyll and rhodopsin-containing bacteria, anerobic methane
oxidation in marine sediments, and the role of Archaea in deep ocean
waters worldwide. To facilitate these studies, they will use genomic data
to design and construct DNA microarrays for monitoring the composition and
activities of marine microbes.
