Microbial Ecology of Fog

agu2011_page_14.jpg

Coastal advective fogs play an as-yet underappreciated and under-researched role in materials exchange between aquatic and terrestrial systems. Because fog droplets are known to contain high concentrations in nutrients (N and P) required for microbial metabolism, microbial life may be making a living while suspended in a cloud droplet, and not just catching a ride. Our lab studies the microbial ecology of coastal advective fogs, with primary interest in the ecological structure fog can provide (albeit temporarily) in the atmosphere. This role is similar to clouds, but fog’s proximity to water and land surfaces results in more direct interaction with microbes ejected from local sources, including the ocean, plants, and humans.
