It is a surprisingly difficult talk to edit through the imagery produced by Remotely Operated Vehicle SuBastian. The dives on the hydrothermal systems of the Mata Volcanic Group have been exciting: both visually and contextually stunning. The landscape is so unfamiliar – so pristine and spectacular – that viewers might find themselves lacking any reference … Continued
“It is hard to pick the most exciting things that we’ve learned on this expedition, because we have learned so much!” Highlights include a diversity of volcanic styles, distinctive sites, traces of past activity throughout the volcanoes individual formations, and much more. Watch the wrap up video for the #UnderWaterFire expedition to see, discover, and … Continued
The swell seems invisible, but is clearly revealed by Falkor’s rocking and rolling. It represents no challenge for the experienced crew and by the end of the day, ROV SuBastian is safely back on the aft deck after twelve hours of exploring the sea bottom. While the cloudscape glows a beautiful purple and orange tint, … Continued

Often, the hidden side of science happens in the lab after the research cruises are finished and we haul our samples/data back to the lab. The hard work that occurs on the ship is just the beginning of the research we do. At the University of Hawaii SOEST Isotope Lab, we specialize in measuring the … Continued
Scientists used to think the deep sea would be like a desert: devoid of life. No sunlight could reach through these depths, and without photosynthesis, how could organisms grow or feed? Take a look at some of the 4K highlights and hear #UnderwaterFire Deep Sea Biologist Dr. Walter Cho explain why that assumption was incorrect … Continued
We’re making dives with ROV SuBastian in the NE Lau Basin, located between Fiji and Samoa in the waters of Tonga, but you might be wondering where all these volcanoes are. Here’s a map showing the various areas we’ve been diving in, covering the wide diversity of volcanism within this small area. On the right edge … Continued
On the #UnderwaterFire expedition, researchers are solving volcano related puzzles, piecing together the history of several close – and related – submarine volcanoes. The Mata Volcano group is a one-of-a-kind natural laboratory from which we can learn a huge amount about some of our planet’s fundamental processes: magmatism and volcanism. Take a look at some … Continued
On ROV SuBastian’s Dive S93 we visited West Mata volcano, where we know multiple eruptions have occurred over the last decade from before-and-after bathymetric surveys. These eruption sites are scattered all over the volcano – some near the summit and others low on the flanks. One of our main goals on this expedition has been to explore many … Continued
