Description:From June to August 2018, the eruption of the Kilauea volcano on the island of Hawai‘i injected millions of cubic meters of molten lava into the nutrient-poor waters of the North Pacific Subtropical Gyre. The lava-impacted seawater was characterized by high concentrations of metals and nutrients that stimulated phytoplankton growth, resulting in an extensive plume of chlorophyll a that was detectable by satellite. Samples for particulate metabolites were collected from different stations surrounding the lava flowing into the ocean to see how marine microorganisms respond to exogenous inputs of nutrients and metals.
