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.

Underwater Fire: Studying the Submarine Volcanoes of Tonga

Why are the researchers searching for submarine volcanoes here? What do they hope to discover? How will they be searching?

We Probably Should Have Waterproofed That: Terrestrial Volcanism

Yesterday we were investigating marine volcanism via underwater fumaroles, and today we’re exploring the terrestrial side of Dominica! Scott Brame, a professor at Clemson University, took us to some of the most interesting geological features this volcanic island has to offer.

Lauren and the giant pumice

The submarine volcanism Chapman Conference is at an end, and by all means it was a success. We had 102 scientists from 13 countries, including 27 students, attend. Submarine volcanologists got to talk to subaerial volcanologists. We saw cool videos of scientists pouring lava over water and ice. We went on a field trip and saw seals and dolphins. We talked about lots and lots of volcanoes (I stopped counting at 27).

Animals of the Tasman Peninsula

On Wednesday, we took a field trip to the Tasman Peninsula to see some of Tasmania’s native animals in their natural habitat. Our first stop was the Tasmanian Devil Unzoo. According to the owners, the unzoo is the complete opposite of a zoo. Instead of displaying animals in cages and enclosures, the unzoo allows visitors to interact with animals (both wild and resident) in their natural environment. There are few enclosures and mostly open space where animals are free to come and go as they please.

Hobart, Day 1

I really knew next to nothing about Tasmania before this trip was planned. I didn’t even know if it was officially part of Australia (it is). I thought it was basically unexplored wilderness with kangaroos hopping around everywhere. But that is not the case. Tasmania actually has cities and suburbs and it looks pretty much like everywhere else.

Exploring underwater volcanoes from down under

Yesterday, I arrived in Hobart, the capital of Tasmania, after a dizzying 30-hour trip from Washington, DC. I exchanged the frigid cold of the US East Coast for the warm 70-degree weather of this tiny island off the coast of Australia. It’s by far the furthest south I have ever been. What am I doing here? I’m attending the AGU Chapman Conference on submarine volcanism that will take place next week. At this point you may be wondering: what’s a Chapman Conference? And what the heck is submarine volcanism?
