variableName: d18O

description: inferred seawater
basis: coral based d18Osw/SSS lags the precipitation by several months, "Thus, SSS may also be influenced by ocean advection in the nearby seas."

scope: climate
scope: climate
basis: Timor d18Osw shows higher SSS during the NW monsoon (September to February). The coral-based SSS record also confirms a delayed response of seawater freshening, which lags the wettest months by several months.

variableName: d18O
units: permil
description: carbonate
basis: d18O is influenced by multiple environmental parameters (i.e., SST, d18Osw, and SSS, the latter controlled by the P-E balance and oceanic advection) in the Indonesian region
