3D rendering of Axial Base
A variety of geophysical sensors are deployed at the base of Axial Seamount to monitor seismic events on the Juan de Fuca plate.
3D rendering of Axial Caldera
Axial Seamount is the most magmatically robust volcano on the Juan de Fuca Ridge spreading center. It hosts numerous active hydrothermal fields and abundant sites of diffuse flow.

The cabled geophysical array at the Central Caldera Site is focused on measuring the inflation and deflation of the volcano, earthquakes, and the movement of of molten lava within the core of the volcano. Bathymetric data are from D. Clague and D. Caress, MBARI. Image Credit: University of Washington.

During Jason Dive J2-980, the remnants of multiple lava lakes from the April 2011 eruption of Axial Seamount were encountered. The bathtub rings mark the progressive lowering of the "lake". Credit: UW/OOI-NSF/WHOI; J2-980; V17.

Tubeworms with red plumes grow on the side of an odd basalt formation formed as part of a fossilized lava lake at the summit of Axial Seamount in 2011. Depth is ~1500 m. UW/OOI-NSF/WHOI; J2-980; V17.

This science pod was cut loose from the Axial Base Shallow Profiler mooring on Sunday morning and was throughly cleaned by an eager group of students. The growth visible on the pod comes after just one year in the water, and since many of the instruments on the pod require unobstructed intake lines for sampling, the pods must be replaced yearly.

The Cabled Array high power and bandwidth fiber optic cables extend from coastal to blue water environments, that include the Cascadia Subduction Zone and the largest volcano off of the Washington-Oregon coast, Axial Seamount. The ~ 900 km of cable provides two-way communications and data flow at the speed of light to 140 instruments and 2900 m-tall moorings with instrumented profilers that have been operational since 2015.
