- Analysis of the physical factors affecting the inflow of Sargassum horneri into adjacent seas of Jeju Island using particle tracking experiment
- Abstract
- Massive Sargassum horneri (Turner) C. Agardh was found in the south-western coasts of the Korean Peninsula (KP) and around Jeju Island in 2015 and had caused enormous damage to fishing and aquaculture industries. The drifting S. horneri in the East China Sea (ECS)/Yellow Sea (YS) was sometimes detected by satellite images from Geostationary Ocean Color Imager (GOCI), but it is not well known its origin, inflow path, and physical factors affecting the inflow. This study investigates the origin and detail inflow path of S. horneri into the adjacent seas of Jeju Island and what the physical factors influence the inflow through a series of particle tracking numerical experiment.
Numerical results reveal that S. horneri found in the western seas of Jeju Island originated from two regions of China, the south of the Shandong Peninsula from December to early January and the Jiangsu province from late January to mid-February. S. horneri in the northern part of Jeju Island Island originated from the north of the Shandong Peninsula in early December and was moved by winter monsoon and tidal residual current. S. horneri in the southern part of Jeju Island originated from the southern coast of China below 33oN from December to January and was moved along the Kuroshio Current. It is also found that the magnitude of northwesterly winds in the YS in December is a main factor that determines the annual amount of S. horneri inflow toward Jeju Island, indicating that it can be used as a potential predictor of S. horneri inflow.
