Join us for a live chat with artist Lily Simonson aboard the Exploration Vessel Nautilus, which is studying an active volcano beneath the Caribbean Sea. A painter and educator from Los Angeles, Simonson is fascinated by the otherworldly animals of the deep sea, especially those that live around the superheated waters gushing from cracks on undersea volcanoes. She’ll tell us what it's like for an artist to collaborate with scientists at sea and what strange invertebrates she hopes to document.

We Make the Treasure by Paul Ramirez Jonas June 19, 2014–January 2015 Location: Exploratorium Pier 15 Admission: Free The second installment in the Over the Water series of large-scale, commissioned artworks. Explore the value of objects lost and recovered, above and below the water line, at We Make the Treasure, the second installment in our Over the Water series of large-scale commissioned artworks. By traversing layers of present-day experience and forgotten history, we invite you to investigate the visible and invisible forces that make something a treasure. Ephemeral, pulsing lines of air bubbles break the surface of the water between Piers 15 and 17, suggesting the ghostly outline of the Beeswing, a schooner that sank on February 17, 1863, as it returned to San Francisco from Monterey. Near the bubbling wreck is a rowboat loaded with mysterious cargo. Visitors are invited to interact with the imagined treasure of the Beeswing by using a crane to find and exchange a haul comprised of coin-sized objects of indeterminate value. We Make the Treasure is curated by the Exploratorium’s Center for Art & Inquiry in collaboration with the Studio for Public Space. Nato Thompson, chief curator of Creative Time in New York, served as advising curator.
