The FAZAR study area is affected be the presence of the Azores Current and Mediterranean Water (MW). Although the MW core has been mapped as far north as 50 degrees N off the ridge; the northern boundary Of the MW within the MAR in the FAZAR study area exists as a strong front south of the Azores platform. This front is most likely caused by the shallower ridge crest becoming a physical barrier to the MW. The Lucky Strike segment lies within this front and, as a result, has complicated hydrography which can obscure hydrothermal temperature and salinity anomalies.
