Summary: Site U1527 (proposed Site NWC-1A) is located on the rim of the NW Caldera wall of Brothers volcano at a water depth of 1464 m. Drilling targeted what was considered to be either the margin of an older, modified seawater hydrothermal upflow zone and/or a recharge zone to the currently active discharge areas several hundred meters northwest and southeast of the drill site, respectively. A key objective of Expedition 376 was to quantify the mechanisms and extent of fluid-rock interaction and the consequences for mass transfer of metals into the ocean in both seawater-influenced and magmatically influenced hydrothermal systems in the caldera of Brothers volcano. Hence, the main objective of Site U1527 was to drill through the margin of the inferred upflow zone of a Type I (modified seawater) hydrothermal system.
