South Pacific Convergence Zone (SPCZ) Solomon Islands and Vanuatu sediment core age models

DOI

Sediment core age model data from South Pacific Convergence Zone sediment cores collected from five freshwater lakes on Tetepare and Rendova Islands in Solomon Islands, and Thion Island in Vanuatu. Age models allow for 500-to-1000-year records of pre-instrumental precipitation variability in the western portion of the SPCZ based on the hydrogen isotope composition of the dinoflagellate biomarker dinosterol. Age models are from 6 cores from 5 lakes: Harai Lake #1, Barora Pond, Lake Tavara, Red Lake, and White Lake (cores Rendova_SHAR1UC2, Tetepare_SBARUC2, Tetepare_SBARUC3, Tetepare_STAVUC4, Thion_VTRUC3, Thion_VTRUC2). Magnetic susceptibility data from 2 cores Tetepare_SBARUC2 and Tetepare_SBARUC3 allowed alignment of radiocarbon dates for the most complete age model to apply to this Barora pond site.
