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.

Axial Seamount seafloor-mapping expedition
September 4, 2019 – The R/V Rachel Carson just returned from a successful 18-day mapping expedition at Axial Seamount, off the coast of Oregon.

Northern 2016 Expedition
From July 26 to August 16, 2016, MBARI researchers used the R/V Western Flyer and the remotely operated vehicle Doc Ricketts to study underwater volcanoes off the coast of Oregon and Washington. They documented their expedition in stunning photos and daily blog entries.

MBARI researchers help map and scout for hydrothermal vents in Gulf of California
Nov 1, 2018 – Building on their 2015 expedition, MBARI researchers will be mapping the Pescadero Basin and searching for hydrothermal vents.
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.
