Axial Seamount Earthquake Catalog
by William Wilcock

New Community Tool – Near Real Time Earthquake Catalog

A new Community Tool, created by Dr. William Wilcock of the University of Washington, in collaboration with Drs. Maya Tolstoy and Felix Waldhauser of Lamont Doherty Earth Observatory at Columbia University, provides near-real time documentation of earthquakes on the Axial Seamount using OOI seismometer data. The OOI Cabled Array spans the Juan de Fuca tectonic […]

The HD camera (orange triangular frame) images the 14 ft-tall actively venting hot spring deposit ‘Mushroom’ located within the caldera for Axial Seamount. The vent rests on an old lava flow. Radiating cracks in the  flow are filled with white bacterial mats and small tube worms, marking sites of diffusely flowing fluids that issue from the fractures in the basalt. The 3-D temperature array in the background encloses a tube worm bush, sending 24 temperature measurements live to shore every second. Photo Credit: NSF-OOI/UW/CSSF; Dive R1730; V14

Axial Seamount Hydrothermal Vent Time-Lapse Videos

Undergraduate students at Rutgers University have used still frames extracted from the HD Video camera (CAMHD) to compile time-lapse videos of the hydrothermal vent, under the direction of the OOI Data Team. There are 7 biological scenes of interest, captured during the pan/zoom routine of each video. The students are helping produce metadata by time-stamping […]

[Science Highlight] Two years of Pioneer Gliders: A track line view

In July, the OOI CGSN operations team completed another “refresh” of the Pioneer glider fleet. The nominal lifetime for OOI coastal gliders (battery limited) is 90 days. The fleet is refreshed by recovery of exhausted gliders and deployment of refurbished gliders with fresh batteries. The Coastal Pioneer Array is designed to have 6 Coastal Gliders […]
