Phytoplankton blooms can be an important source of autochthonous chromophoric dissolved organic matter (CDOM) in surface oceans.	表层海水中有色溶解有机物 (CDOM) 的一个重要自生来源是浮游植物的藻华。
Here we report the first detection and optical characterization of CDOM produced during a Dictyocha fibula bloom occurring in the western central Bohai Sea in mid-summer 2019.	2019年仲夏，我们在渤海中部偏西的海域观测到一次小等刺硅鞭藻的藻华，对于本次藻华释放的 CDOM 及其光学性质，我们首次进行了报导。
The mean CDOM absorption coefficient at 330 nm (aCDOM(330)) in the surface water of the bloom area (3.16 ± 0.48 m-1) was 2.5 times higher than that of the adjacent bloom-absent area (1.26 ± 0.34 m-1).	在藻华区的表层海水中，CDOM 在 330 nm 处的吸光系(aCDOM(330)) 平均值为 3.16 ± 0.48 m-1，该值是在临近的背景区内观测平均值 (1.26 ± 0.34 m-1) 的 2.5 倍。
The aCDOM(330) increased exponentially to a maximum with increasing chlorophyll a and cell abundance of D. fibula, indicating a steady state was reached between production and consumption of CDOM.	吸光系数 aCDOM(330) 随叶绿素 a 和小等刺硅鞭藻细胞丰度的增加而呈指数方式升高，直到升至一个最高值，此时 CDOM 的产生和消耗达到动态平衡。
The biological index (BIX) of the fluorescent DOM (FDOM) showed little variation between bloom and background areas.	荧光 DOM (FDOM) 的生源指数 (BIX) 在藻华区与背景区内都变化甚微。
The combination of these observations points to an extensive production of autochthonous CDOM by D. fibula in the bloom area.	这些观测结果表明，藻华区内的小等刺硅鞭藻释放了大量的自生源 CDOM。
Mass budgeting indicates that the CDOM source from D. fibula (aCDOM(330): 1.98 ± 0.48 m-1) accounted for 63% of the CDOM stock in the bloom area.	根据质量守恒原理计算得出，小等刺硅鞭藻产生的 CDOM (1.98±0.48 m-1)占藻华区 CDOM 总量的 63%。
The spectral slope coefficients over 275–295 nm (S275–295) in the bloom area (range: 0.0228–0.0241 nm-1; mean: 0.0235 nm-1) were substantially lower than those in the bloom-absent area (range: 0.0240–0.0311 nm-1; mean: 0.0271 nm-1), suggesting a high-molecular-weight nature of the D. fibula-derived CDOM.	藻华区 CDOM 在 275 nm-295 nm 波段的光谱斜率（S275–295) 的测量值 (范围：0.0228-0.0241 nm-1；平均值：0.0235 nm-1) 远低于背景区的值 (范围：0.0240-0.0311 nm-1；平均值：0.0271 nm-1)，这表明小等刺硅鞭藻产生的 CDOM 具有较高的分子量。
The freshly produced CDOM contained two humic-like FDOM components and one protein-like FDOM component, and the three FDOM components were depleted in fresh CDOM relative to their counterparts in CDOM within the background area.	新产生的 CDOM 包含三种 FDOM 组分，其中两种属于类腐殖质，一种属于类蛋白质；这三种 FDOM 组分的含量低于其在背景区内 CDOM 中的含量。
Owing to the episodic nature of algal bloom-driven CDOM production, future attention should be paid to accelerated biogeochemical cycles (e.g., spiked oceanic trace gas emission) associated with CDOM photochemistry during algal blooms which can be easily missed for pre-scheduled field surveys.	藻华的爆发是随机的，藻华释放的 CDOM 亦然；而出海调查都是提前规划好的，不一定恰好遇见每一次藻华。
