Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Northern EPR at 10.7°N
A temperature probe from the submersible vehicle Alvin collects data at a low-temperature hydrothermal vent located in a collapse structure in the East Pacific Rise area. The maximum temperatures reached only 9.5°C. This lava flow was erupted within only a few weeks to a few months of this November 2003 expedition. The flow was covered by bacterial mats, had large amounts of bacterial floc issuing from diffuse vents, and was sparsely populated by small animals. Photo courtesy J.R.

Divers in the submersible Alvin discovered an extremely fresh lava flow in an unexpected location at 10°44'N on the East Pacific Rise during an expedition in November 2003. The young flow was covered by bacterial mats, had large amounts of bacterial floc ("snow-blowers") issuing from diffuse vents, and was sparsely populated by small animals. Uranium-series dating indicated that the eruption had taken place within a time window only a few months to weeks prior to the observations. This segment of the East Pacific Rise, located just north of the Clipperton Transform Fault, is an area with an estimated low magma production rate.
