Griffin Photo provided by Dr. Griffin Dale Griffin is a microbiologist with the USGS Center for Coastal Geology and Regional Marine Studies in St. Petersburg, Florida. He has been involved in a series of studies centering on the effects of globally transported African and Asian dust on coral reefs and human health. Studies by other researchers have shown that each year from February to April, winds bring an estimated 13 million tons of dust to the Northeastern Amazon Basin, and from June to October the winds shift and typically bring dust to North and Central America and the Caribbean. To date, Dale Griffin has isolated numerous species of viable bacteria and fungi from air samples taken during dust events (U.S. Virgin Islands, tropical mid-Atlantic ridge, Turkish Mediterranean coastline, North Pacific); samples collected during non-dust periods contain few microorganisms. Dale is also involved in aquatic microbiology studies to include source tracking of human waste in marine and freshwater environments, indicator/pathogen identification, and microbial ecology issues.
