| Recent studies illustrate that climate change may enhance the frequency and strength of typhoon. But the impact of a typhoon on carbonate parameters is still unclear. On the Northeast Pacific Ocean, a region usually affected by tropical cyclones, we surveyed the Southern East China Sea (SECS) and collected dissolved inorganic carbon (DIC) and total alkalinity (TA) water samples. In particular, one leg of this cruise (from July 6th to 9th 2018) is right before the Typhoon Maria (July 10th to July 11th 2018) and the other leg is right after this Typhoon (July 13th to 17th 2018). The preliminary results displayed an upwelling at waters off the northeastern Taiwan. In surface waters, higher DIC concentrations were observed at this upwelling region than those values in the rest area before typhoon. Furthermore, these surface DIC concentrations were largely increased after this typhoon. The implication of this typhoon will be discussed in this poster. |
