July 21: A Journey Into our Unseen World

The University of Delaware School of Marine Science and Policy’s popular Ocean Currents Lecture Series continues Thursday, July 21, with a talk by UD’s David Kirchman, Maxwell P. and Mildred H. Harrington Professor of Marine Biosciences.

Ocean Currents lectures take place once a month from May through August. Talks begin at 7 p.m. in Room 104 of Cannon Lab at UD’s Hugh R. Sharp Campus on Pilottown Road in Lewes. The events are free and open to the public, but reservations are required.

The July lecture, titled “A Journey Into our Unseen World: Marine Microbes and Global Cycles,” will focus on some of the environmental roles played by some of the oceans’ tiniest inhabitants.

With alarming increases in carbon in the Earth's atmosphere, scientists and policy makers across the globe are drawing upon Kirchman’s research into how microbes participate in the carbon cycle and other bio-geochemical processes of the oceans.

“We live on a blue planet,” Kirchman said. “If we want to talk about carbon, we have to talk about the oceans.”

Carried out in collaboration with colleagues and students, Kirchman’s work has demonstrated that microbes are the most abundant organism in the biosphere, are important in marine food webs, and are responsible for mediating many critical chemical reactions in nature. Kirchman's research has taken him and his students to most of the world's oceans, from the Arctic to Antarctica.

For reservations, which are required due to limited seating, contact Michelle Scorziello at mkscorzi@udel.edu or 302-645-4346. Light refreshments are served at the hourlong lecture.
