Melville, a Scripps Institution research vessel, will dock at the Exploratorium May 10–13 before embarking on a 25-day mission to study the effects of ocean acidification—the chemical changes caused by increasing carbon dioxide levels in the atmosphere. Join the mission’s chief scientist, Romberg Tiburon Center’s William Cochlan, to hear how his team will study the impact of acidification on tiny, plantlike organisms called phytoplankton, which are the foundation of all oceanic food webs.

Cochlan and his team will cruise from Monterey Bay to Seattle, gathering samples of phytoplankton. They’ll study the plankton’s growth rates and the kinds of fats they contain, and how those factors respond to the ocean’s acid content.
