Submarine volcanism cruise logs
The Submarine Volcanism group has traveled to the NE Pacific, the Gulf of California, off the California coast, Hawaii, the Lau Basin, and the south Pacific (Lau Basin, Pacific-Antarctic Ridge and Southern East Pacific Rise) to study mid-ocean spreading ridges, seamounts, and hot spot volcanoes, and continental margin processes. From each of our cruises we have posted daily cruise logs to share our experiences at sea.
New study challenges prevailing theory about how deep-sea vents are colonized
Jul 24, 2017 – Despite their close proximity, two recently discovered hydrothermal vent fields in the Gulf of California host very different animal communities. This finding contradicts a common scientific assumption that neighboring vents will share similar animal communities.
MBARI’s seafloor maps provide new information about 2015 eruption at Axial Seamount
Dec 15, 2016 - Axial Seamount, a large underwater volcano off of the Oregon coast, is one of the most active volcanoes in the world, having last erupted in 2015. At the Fall 2016 meeting of the American Geophysical Union, MBARI researchers unveiled a new seafloor map that reveals previously undocumented lava flows from the 2015 eruption.
MBARI researchers discover deepest known high-temperature hydrothermal vents in Pacific Ocean
Jun 2, 2015 – In spring 2015, MBARI researchers discovered a large, previously unknown field of hydrothermal vents in the Gulf of California, about 150 kilometers (100 miles) east of La Paz, Mexico.
