Ocean Sound

Highlights:

First CO2 gas flow estimate from a submarine volcano:
Using hydrophone records of volcanic explosion sounds and melt inclusion data, Vents scientists were able to estimate the yearly amount of carbon dioxide gas emitted from a submarine volcano. The results, published in the journal G-cubed (pdf), show that the 500 m deep volcano NW Rota-1 (located in the Mariana Island group) expels ~0.4 Tgrams of CO2 per year, or roughly 1% of the global CO2 contribution from subaerial arc volcanoes.

Precursors to Eruption at Axial Seamount Found:
NOAA Vents scientists recently published papers in the journal Nature Geoscience that show, for the first time, that precursory signals were recorded by seafloor instruments before an undersea volcanic eruption at Axial Seamount in 2011. Such signals could be used to issue long-term and short-term forecasts of future eruptions at the site

Undersea hydrophones captured the sounds of the March 11 Mw 9.0 earthquake that shook Japan and sent a tsunami wave across the Pacific Ocean.  The hydrophones recorded the seismic and acoustic arrivals of the earthquake, known as P- and T-waves respectively.
