An interesting geothermal energy prospect in the Vienna Basin…and its connection to oil and gas
In effect, the hydrogeothermal project is doing just what oil and gas exploration does–looking for and extracting desirable fluids in the subsurface. In this case, the desirable fluid is hot and readily flowing water…

Submarine Volcanoes of Tonga: What is the point?
An unrelenting love for discovery drives the scientists’ quest. Dr. Chadwick smiles when he says, “I love the thrill of figuring something out for the first time, like looking at a landscape and interpreting how it was formed.”

Underwater Fire – Week 2 Video
“On these expeditions, I always have to remind myself that what we are seeing on the video screen or computer monitor is not somewhere else – it is right under our feet!”

New Views of the Seafloor
The finer detail in the Sentry bathymetric maps allows us to see much smaller features like eruptive vents, volcanic craters, lava flows of different ages and textures, faults, fissures, and landslides, and if we are lucky, even hydrothermal vents.

Where there is smoke…
The chemistry of seawater around volcanoes is different from that of the rest of the ocean. When the team runs into these differences over a volcano, they are most likely from a hydrothermal source.

Fire Meets Water
Like a domino effect, several things happen to seawater when it comes in contact with a volcano.

What is so interesting about submarine volcanoes?
Jagged piles of molten rock, sulfurous smoke, exploding gaseous emissions, shifting landscapes, otherworldly creatures, scalding acidic fluids, swirling plumes of volcanic gasses and particles, and crushing pressure of the overlying sea: what is not to like about active submarine volcanoes?

Our first discovery!
Immediately after we collected the new bathymetric survey over West Mata, we gridded it and made a comparison to the last survey in March 2016. To our delight, two areas with large depth changes jumped out of the comparison.

Underwater Fire: A Changing Landscape
West Mata is a Restless Volcano. West Mata Seamount is one of only two submarine volcanoes in the world where an active eruption has been directly observed on the seafloor.
