International Ocean Discovery Program (IODP) Site U1488 is located atop the southern part of the Eauripik Rise at 02°02.59ʹN, 141°45.29ʹE in 2604 m water depth. Site U1488 is situated on the Eauripik Rise, within the Caroline Basin north of Papua New Guinea. Site U1488 is located ~2° north of the Equator and is thus suitable for reconstructing the hydrographic history of the WPWP. The comparatively low sedimentation rate at this site, typical of open-ocean environments, will be used along with the record from Site U1490 to reconstruct the evolution of the WPWP since the late Miocene. At 2600 m below sea level (mbsl) the site is bathed by modified Upper Circumpolar Deepwater and therefore will be useful to monitor past changes in this water mass. High-resolution interstitial water sampling at this site will be used for geochemical reconstructions of the deep Pacific water mass (δ18O, salinity, and seawater chemistry) during the Last Glacial Maximum (LGM).
