wAbstract
@We have performed the first known semicontinuous monitoring of
particulate organic carbon (POC) fluxes and dissolved Si concentrations
delivered to the ocean during a typhoon. Sampling of the Choshui
River in Taiwan during Typhoon Mindulle in 2004 revealed a POC
flux of 5.00~105 t associated with a sediment flux
of 61 Mt during a 96 h period. The linkage of high amounts of
POC with sediment concentrations capable of generating a hyperpycnal
plume upon reaching the ocean provides the first known evidence
for the rapid delivery and burial of POC from the terrestrial
system. These fluxes, when combined with storm-derived CO2 consumption of 1.65~108 mol from
silicate weathering, elucidate the important role of these tropical
cyclone events on small mountainous rivers as a global sink of
CO2.
