The Pacific Marine Environmental Laboratory (PMEL) conducts global and regional oceanographic research in support of the National Oceanic Atmospheric Administration’s (NOAA’s) three mission areas: (1) understanding predicting changes climate, weather, oceans, coasts; (2) sharing that knowledge with others; (3) conserving managing coastal marine ecosystems resources. Since its establishment 1973, PMEL’s work has ranged from pole to across ocean. lab’s examined ocean structure function physical, chemical, biological realms, informed supported development US policy these areas.

Abstract The powerful eruption of Hunga volcano (15‐January‐2022) excavated ∼6.3 km 3 pre‐existing material, leaving behind an 855 m deep crater. scientific and humanitarian response to this event was challenging due the remote location, safety concerns, COVID‐19 pandemic restrictions. To investigate status ongoing eruptive/hydrothermal activity, study used, for first time, un‐crewed surface vessel operated remotely from >16,000 away make direct water column measurements within crater map its structure in detail. Intense turbidity oxidation‐reduction potential (ORP) anomalies located activity at sites on steep inside slopes near both remaining islands. Mid‐water acoustic reflectors indicated degassing, positive ORP suggested gas composition dominated by CO 2 . At least 75% rim is shallower than 100 m, so any exchange with surrounding ocean limited depths breaches (185 between islands 290 ENE side). This post‐eruption bathymetry results accumulation emission products There were no indications visible surface, which highlights limitations inherent biases associated relying discolored and/or atmospheric disturbances determine start/end dates submarine volcanoes. demonstrates value need add repeat hydrothermal plume bathymetric surveys our toolbox monitoring volcanoes, un‐crewed, vessels contribute significantly these efforts.
