Notes on Vent Field Description:
2015 ROV Doc Ricketts Dive 744 in Tamayo Transform near southern end of Alarcon Rise; spreading rate is given here for the Alarcon Rise step in Bird (2003) plate model; MBARI website, accessed 11 May 2015, http://www.mbari.org/expeditions/GOC15/Leg5/April8.html: "there are some differences between our observations and a typical cold seep that suggest our clams are benefiting instead from very low-temperature hydrothermal venting driven by still hot volcanic rocks.", " this may be the first low temperature hydrothermal seep from a transform"; note that this database entry may ultimately be determined to be a hydrothermal seep or cold seep
