| Abstract: |
| From November 24 to 26, 2014, a red tide event occurred in the offshore water off the Hailing Island located at the western Guangdong coast. The red tide appeared as pink strips distributed within 3 km in the offshore water and extended for about 10 km along the shoreline. during the flood tide, the pink seawater rushed to the beach with breaking waves, forming foam strips on the beach. Guangdong Province Key Laboratory for Coastal Ocean Variation and disaster Prediction Technologies, Guangdong Ocean University, emergently responded to the event and organized three-dimensional observations from the air, onboard and on beach. The preliminary analyses of the cruise data and water samples indicate that the event was induced by nontoxic Noctiluca scintillans, of which the concentration reaches as high as 4 200 cells/L near the surface and 2 600 cells/L at the bottom. |

| 2014年11月24日至26日, 粤西沿岸海陵岛近岸海域发生一次赤潮事件. 赤潮在近岸3 km范围内呈红色条带状分布, 沿岸绵延约10 km. 涨潮时, 红色海水随浪冲向岸边, 在沙滩上形成红色泡沫条带. 广东海洋大学的广东省近海海洋变化与灾害预警重点实验室应急对此次赤潮事件进行了岸边、海上和空中的三维观测. 现场观测和水样的初步分析显示: 此次赤潮是由无毒的夜光藻(Noctiluca scintillans)引起, 其最大浓度在海表和海底分别达到4200 cells/L和2600 cells/L. |
