英文摘要In Summer 2024, a dinoflagellate bloom broke out in the Bohai Sea along the north coast of Shandong peninsula. By approaches of morphological observation, pigment analysis and targeted gene sequencing, the bloom causative species was identified as dinoflagellate Takayama acrotrocha. The satellite imagery indicated that the bloom lasted from August 24 to September 8, and distributed mainly in the coastal waters extending from the Yellow River estuary to Yantai and Weihai, marking the northward expansion of this algal species along the coast of China. Analysis of key environmental factors revealed that intensified precipitation in the Shandong peninsula in Summer 2024 led to reduced sea surface salinity (SSS) in the northern coastal waters relative to the average level of 2019-2023, while unusual warming resulted in elevated sea surface temperature (SST) during the same period. Ultimately, the climate-driven conditions-increased runoff from the Yellow River, associated nutrient enrichment in the coastal waters, and high SST-collectively promoted the first T. acrotrocha bloom ever recorded in the Bohai Sea.
