PORT TOWNSEND — University of Washington oceanography professor Deborah Kelley will present “Submarine Volcanoes, Vents and the Life They Support” at the Fort Worden Chapel at 3 p.m. Sunday.

Admission is $10 for the general public and $5 for Port Townsend Marine Science Center members.

Kelley will focus on hydrothermal systems along the Juan de Fuca Ridge and the Lost City hydrothermal field that she helped discover in 2000.

Kelley serves as the director for the underwater cabled component of the Cabled Array, a project that includes the installation of hundreds of miles of high-power and bandwidth fiber optic cables on the seafloor that stream real-time data to shore.

Her work is made possible by extraordinary advances in marine monitoring technology, including the National Science Foundation’s Ocean Observatories Initiative, known as the Cabled Array.

The monitoring equipment streams live, real-time data to shore, providing new insights into submarine earthquake generation, ocean acidification, climate change, an active underwater volcano, methane seeps and the extreme environments of hydrothermal vents.

This is the first of four presentations in the Port Townsend Marine Science Center’s third annual Future of Oceans Lecture Series, sponsored by the Darrow family.
