As anthropogenic warming continues it is important to assess responses in the climate from the climatologically significant West Pacific Warm Pool (WPWP). The warm waters in the WPWP modulate atmospheric convection and rainfall including in the rainfall band known as the South Pacific Convergence Zone (SPCZ). However, these interactions are not fully understood. This study aims to investigate whether corals from the Lau Lagoon seascape, Malaita Province, Solomon Islands, within the WPWP/SPCZ region can be used to extend WPWP/SPCZ climate records and thereby improve understanding of these climate ‘cogs’. Two modern coral samples that span up to twelve years of climate data from the north and south of Lau Lagoon were used to reconstruct present-day variability of the climate and test if the corals are accurate recorders of the local and regional climate. The coral samples were analysed for Sr/Ca to investigate the corals’ potential to record SST variations, luminescence for run-off ....
