Abstract
Site U1550 is located within the axial graben of the northern Guaymas Basin spreading segment (Figures F1, F2). This site was established very close to Deep Sea Drilling Project (DSDP) Site 481 to take advantage of the known presence, depth, and characteristics of sills and indurated sediments at Site 481 (Shipboard Scientific Party, 1982), and to clarify its stratigraphy by redrilling it with improved coring tools and sampling approaches. Substantially improved recovery was expected relative to Site 481, leading to increased sampling resolution of downhole changes and enabling the use of modern microbiological approaches. The fault-bounded setting of Site U1550 provides the potential for high-flux fluid circulation in response to sill intrusion, leading to swift cooling and potentially enhanced alteration due to the rapid removal of dissolved phases and gases. The primary objectives for Site U1550 were to characterize the physical, chemical, and microbial responses to sill intrusion into sediments at a high-flux end-member location.
