van der Zander I, Rubin K H, Zierenberg R A, Voight J R, von Damm K, McClain J, 2004. 210Po-210Pb dating and U-series disequilibria of a young basaltic flow at 10° 44' N EPR. Eos, Trans Amer Geophys Union, 85(47): abstract B13A-0178.

Divers in the submersible Alvin discovered an extremely fresh lava flow in an unexpected location at 10 degrees 44 minutes North 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.
