Maps showing sampling stations in the coasts of Tongyeong (A region) and Yeongdeok (B region), Korea. The gray filled arrow is a general concept of the spread of red tides based on a particle-tracking model and satellite remote sensing reported by Onitsuka et al.6, Choi et al.32, and Kim et al.33. The date indicates the timing of red-tide warning in 2014. The red open-circled stations denote the center of the red-tide patches. The station maps were created using Ocean Data View software version 5.1.7. (Schlitzer, R., Ocean Data View, odv.awi.de, 2018) and modified using Adobe Illustrator CS6 software version 16.0.0.
