Sentinel-2的胶州湾水体透明度遥感反演

Using a variety of observation data from satellite and BGC-Argo, this work investigates the influence of Typhoon Hagibis on ecological responses of the upper ocean in the Northwest Pacific Ocean. Measurements of chlorophyll-a concentration and sea surface temperature from Himawari-8 associated with Typhoon Hagibis were analyzed. The results show that the chlorophyll-a concentration along the typhoon track increased within 2-3 days after its transit, and the maximum value reached 0.3 mg/m3 or even higher while the sea surface temperature responded until 4-5 days later, with seawater cooling by 0.17-0.3°C. The observations of BGC-Argo demonstrate that Ekman pumping phenomenon may have occurred during the passage of Typhoon Hagibis, which induced the vertical transportation of deeper seawater to the upper and surface ocean, resulting in the increase of chlorophyll-a concentration, the decrease of temperature in mixed layer along the typhoon path.
