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 […]

Workshop Report: Southern Hydrate Gordon Conference

This report summarizes discussions from a mini-workshop held after the Gordon Research Conference (GRC) on Natural Gas Hydrates March 4-5, 2016. The workshop was focused on opportunities presented by the Ocean Observatories Initiative (OOI) Cabled Array at Southern Hydrate Ridge. Further information on the conference can be found on the conference website. Download the full […]

[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 […]

[OOI in the News] EOS – Ocean Observatories Initiative Expands Coastal Ocean Research

(From EOS, 97) By Robinson W. Fulweiler, Glen Gawakiewicz, and Kristen A. Davis The coastal ocean provides critical services that yield both ecological and economic benefits. Its dynamic nature, however, makes it a most challenging environment to study. Recently, a better understanding of the coupled physical, chemical, geological, and biological processes that characterize the coastal […]

Satellite imagery shows the exchange of warm core ring water (red) with the colder continental shelf waters (blue). Satellite imagery, however, could not help scientists determine the underlying process for the warm water intrusion; instead they used data from ocean robots or “gliders” recently installed off the coast of Massachusetts. The scientists have dubbed the events “Pinocchio’s Nose Intrusions” (PNI) because the warm intruding water continues to ‘grow’ for hundreds of miles, moving in the opposite direction from the northward movement of the Gulf Stream.

Gulf Stream Ring Water Intrudes onto Continental Shelf Like “Pinocchio’s Nose”

Ocean robots installed off the coast of Massachusetts have helped scientists understand a previously unknown process by which warm Gulf Stream water and colder waters of the continental shelf exchange. The process occurs when offshore waters, originating in the tropics, intrude onto the Mid-Atlantic Bight shelf and meet the waters originating in regions near the […]
