Notes on Vent Field Description:
McCarthy, K.T. et al. (2005): "Submarine hydrothermal venting occurs at Champagne Hot Springs in 1-5 m water along the submerged flank of the Plat Pays volcanic complex. The vent field extends approximately 40 m seaward and is 22 m at its maximum width, for a total area of 880 m2. Venting occurs along two east-west trending fissures in the lava rock, demonstrating possible structural control on vent locations and distribution."; "Temperatures of Champagne Hot Spring vent fluids at the point of discharge were between 41 and 71.4 C, while pH was between 5.95 and 6.15"; location from travel website, http://www.avirtualdominica.com/hotwater.cfm, accessed 28 May 2015: "Located about three miles south of Roseau, there is a large area just off the beach where vents allow bubbles of hot water into the sea. The spot is at the far end of a pebbly beach, about a mile south of the village of Pointe Michel."
