Notes on Vent Field Description:
plume not detected by German et al. (1994); May 1989 earthquake swarm on the Reykjanes Ridge at 59 44'N, 29 32'W (location later refined to 59 57'N, 29 45'W); Crane et al. (1997): "A high backscatter possible ‘lava flow’ was discovered at 59 49'N, 29 41'W.", "the region of high-backscatter remains unsampled because it lay underneath the nadir of the processed SeaMARC tracks used to plan the submersible survey."
Notes Relevant to Biology:
Year and How Discovered (if active, visual confirmation is listed first):
1992 submersible Mir did not find vents
