Abstract
(type = abstract)
The western Pacific warm pool (WPWP) is an important regulator of global climate, and the relationship between variations in the physical oceanography within the WPWP and global climate remain poorly understood. High-resolution seismic data provides an opportunity to study the past and make inferences into how ocean dynamics have changed through time. 2D high-resolution multi-channel seismic grids were collected during cruise 1313 of the R/V Roger Revelle in September 2013, in preparation for future drilling by IODP Exp. 363. This study focuses on seismic grid WP2 collected during that cruise on the northern limb of the WPWP on the northern Eauripik Rise. Of the ~500 m thick seismically imaged sediment in the ~ 10 x 15 km survey grid at WP2, there is an ~100 m thick package of buried migrating sediment waves oriented NE-SW with amplitudes of 10-30 m, and wavelengths of 1-2 km. Sedimentation rates derived from piston cores taken on the Revelle cruise 1313, combined with biostratigraphy at DSDP Site 62 (450 km south of WP2 on Eauripik Rise) provided age estimates on sediment wave horizons. The oldest waves at WP2 (~ 14 Ma; 350 mbsf) migrate north and increase in amplitude upsection until a key horizon (horizon i) is reached at ~240 mbsf. At this depth, wave migration stops throughout the grid, and previously increasing wave heights begin to decrease upsection in the southern lines. This shift from strong, long-term current-controlled sedimentation to deposition with no sediment transport occurs at ~10 Ma. Potential correlation with other middle Miocene reflectors in the equatorial Pacific as well as offshore NW Australia imply that the formation of sediment waves from ~10-14 Ma could be associated with the permanent glaciation of Antarctica at 13.8 Ma. Abyssal sediment waves are direct indicators of circulation in the deep sea, and changes in circulation indicated by changes in sediment wave geometry can be associated with climatic fluctuations. Although a localized feature, the sediment waves at WP2 can provide interpretation into how deep water flow has changed through time in this region and how these events correlate to regional and global climatic events.
