Entitled “Submarine Volcanoes: Crucibles of New Seafloor Deposits,” his lecture is free and open to the public.
According to Carey, three quarters of the Earth’s volcanic activity occurs deep beneath the sea, where it builds the foundation of the ocean floor and creates new volcanic islands. Heat from this volcanism produces hydrothermal systems where exotic biological communities occur and where the concentration of precious metals form economically important mineral deposits.
“Recent explorations of submarine volcanoes in the Mediterranean Sea have provided important information about the formation of valuable new mineral deposits on the seafloor,” said Carey. “Utilization of these resources requires a careful balance between protecting unique ecosystems and extracting material for commercial development.”
Carey’s research focuses on the study of explosive volcanism at convergent plate boundaries. He conducts simulations of explosive eruption processes, studies the petrology and physical properties of magmas involved in explosive volcanism, and examines the origin and characteristics of marine volcaniclastic sediments. His recent research projects include studies of the Santorini/Kolumbo volcano in Greece, submarine volcanoes in the Strait of Sicily, and the Kick’em Jenny volcano in the West Indies, which he visited in September.
He earned a bachelor’s degree in geology from the University of Massachusetts and a doctorate in geological oceanography at the URI Graduate School of Oceanography.
Carey’s lecture is sponsored by the Friends of Oceanography and the Graduate School of Oceanography. A reception will follow the lecture.
