Abstract: High Standing Islands (HSIs) experience extremely rapid physical and chemical weathering, resulting in large inputs of both sediments and solutes into the ocean. This can impact the global carbon cycle by the rapid burial of organic C and precipitation of calcium carbonate in the oceans. This poster will provide a progress report on a study of the role of uplift and erosion rates of various regions in Taiwan and its effect on the CO2 and C consumption rates of the area. Taiwan sits on top of a highly active convergent plate boundary between the Eurasian and Philippine Sea Plate, which is the cause of the intense uplift that creates the orogenic mountains that make up the island. The plate margin has uplift rates >10mm/yr and contains erosional features dominated by mass-wasting. The island also contains three of the nine rivers in the world which have average sediment concentrations >10g/l (Milliman and Syvitski,1992). Soil samples from locations on the island subjected to a range of uplift rates will be analyzed for carbon (C), carbonate (CO3), and particle size in order to determine whether variations in soil residence times can impact chemical weathering and CO2sequestration. I expect there to be a higher amount of CO2and C consumption on the island than most anywhere on Earth due to the readily weathered surfaces that result from the rapid uplift and fast erosion rates of the island.
