Summary: Site U1531 (proposed alternate Site LC-1A) is located on the saddle between the Lower and Upper Cones of Brothers volcano at 34°52.7767'S, 179°04.2241'E about 380 m northeast of Seismic Line Bro-3 at a water depth of 1355 m. This site likely sits between the margins of the upflow zones of both the Upper and Lower Cones because no detectable magnetic low was measured in this area. The Lower Cone hydrothermal vent field includes vents that discharge the most Fe- and Mg-rich fluids sampled at Brothers volcano to date, although venting at the saddle was not found. The main objective at Site U1531 was to drill and core to ∼300 meters below seafloor (mbsf) to sample the various volcanic cycles that constructed the Lower Cone and to intersect the marginal upflow zone of hydrothermal fluids.
