Recently published papers on Axial Seamount in the journal Nature Geoscience present, for the first time, precursory signals recorded by seafloor instruments before an undersea volcanic eruption.  NOAA and Oregon State University scientists Dr. Bill Chadwick and Dr. Bob Dziak suggest that such signals could be used to issue both long-term and short-term forecasts of future eruptions at the site.

A newly released report at Oceanography details the work of scientists and engineers with PMEL’s Cooperative Institute for Marine Resources Studies (CIMRS) to analyze the sound of iceberg A52 breaking apart in the Southern Ocean using underwater hydrophones. The authors concluded that sounds measured are significantly greater than anthropogenic noises and should therefore be considered as a major contributor to the overall ocean noise budget.
