520 The tropical Pacific plays a critical role in modern
climate and ocean dynamics, prompting numerous proxy-based
reconstructions of its behaviour on geologic timescales.
Here, changes in the fluvial delivery of terrestrial
matter to the Indonesian Seas are reconstructed for the
last glacial-interglacial transition using abundances of n
-alkanes in six sediment cores along a N-S transect. At
all of the core sites, the flux of n-alkanes is higher
during the Last Glacial Maximum than during the current
interglacial; a signal postulated to be primarily driven
by the deglacial rise in sea level. In contrast, shorter-
term variability is discussed in terms of changing
precipitation regimes. Other factors possibly influencing
the riverine delivery of n-alkanes to the ocean are also
considered, including variable discharge associated with
changing frequencies of intense storm events, variable
rates of erosion and deposition, and variations in local
plant biomass
