Collaborations across the North Atlantic – Reflections on the 2017 Irminger Sea Regional Science Workshop

Late last year, more than 30 researchers from countries spanning the Atlantic met in Southampton, UK at the National Oceanography Centre to foster coordination of research efforts focused on the Irminger Sea region. Of central importance to the workshop was to bring in young investigators. “The Irminger Sea workshop provided me with an incredibly valuable […]

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 […]
