Submarine Ring of Fire 2012: Northeast Lau Basin is the latest in a series of expeditions to explore the submarine volcanoes of the Western Pacific. Our primary objective will be to explore and to characterize the unique ecosystems in the Northeast Lau Basin through examination of their geology, chemistry, and macro- and micro- biology.

We are going to see a variety of submarine volcanism on this expedition, everything from old sediment-covered lava flows to (maybe) an actual underwater eruption spewing plumes of sulfurous gas, ash and perhaps even flowing lava.

The seafloor of the Northeast Lau Basin is one the most volcanically active areas known to scientists. Magma from deep within the crust upwells to the seafloor to form long ridges and symmetrical volcanoes. Cooling of the magma creates seafloor hot springs (hydrothermal vents), which construct mineral deposits, nurture unique biological communities, alter deep-sea circulation patterns, and profoundly influence ocean chemistry and biology.

One of the most astonishing features of hydrothermal vents is the unusually high biomass and fast growth rates of microbes that grow on and around the vents. The biomass is extremely high because of the chemical energy present in hydrothermal fluids.

Natural products chemists have begun to evaluate recently discovered deep-sea vent organisms as a source of small molecule natural products with medicinally-relevant properties. For this exploratory expedition, we will rely on studies of the biology and water chemistry of the targeted vent fields to plan our collections.
