WHOI microbiologist John Waterbury examines phytoplankton samples in his lab in the Stanley W. Watson Biogeochemistry Building. Today Waterbury is joining MIT biologist
Penny Chisholm and WHOI biologist Robert Olson at ProchlorococcusFest, a "science bash" to celebrate the 20th anniversary of the discovery
of the marine microbe. Prochlorococcus is one of the smallest and most abundant photosynthetic organisms in the oceans; nearly 100 million can live in a quart of seawater. The microbes are known to play a key
role in the ocean carbon cycle and, hence, climate
regulation. Chisholm, Olson, and Waterbury were key members of the research team that discovered the microbe and
first described it in the journal Nature in 1988.
