Santa Barbara Maritime Museum presents “All The Life We Cannot See: Marine Microbes and the Health of our Oceans” on Thursday, October 19, 2023 at 7:00 p.m. UC Santa Barbara Professor Alyson Santoro, PhD will discuss the general role of microbes in the ocean, which cycle nitrogen throughout the deep ocean, and the impact and important role the microbes have on the Earth’s climate. Marine microbes are single-celled organisms too small to be seen with the naked eye. They are the most abundant living things in the ocean, where they keep the water and the entire planet habitable for animals—and people. As recently as the 1950s, people believed that the deep ocean was practically devoid of microbial life.

The lecture series is sponsored by Marie L. Morrisroe.
