海水变色 meaning in Chinese

discoloured water

Red tides or algal blooms are natural discolorations of seawater caused by the rapid multiplication of algae
红潮又称为藻华，是由于水藻突然迅速繁殖，而导致海水变色的自然现象。
" the high concentration of the red tide led to a discolouration of water but mariculturists confirmed that fishes in the fish culture zone are normal , " he said
他补充说：由于有高浓度的红潮细胞，因而引致海水变色，但养鱼户证实，区内养鱼均十分正常。
Red tide occurs randomly , with short duration and large incidence . airborne hyperspectral remote sensing technique can play an important role in red tide ' s monitoring . and the precondition is to acquire in situ spectral data of red tide , to grasp red tide ' s spectral characteristics by data processing and analysis and to set up spectral library of different dominant species of red tide
赤潮是海水中的浮游生物在一定条件下过度繁殖或聚集致使海水变色的一种生态异常现象，因其具有随机性、突发性、持续时间短、影响范围大等特点，客观上要求利用航空高光谱遥感技术对其进行监测；但首要的前提与基础性工作是大量获取赤潮水体的现场光谱数据，通过处理与分析，掌握其光谱特性，不断充实赤潮优势种类的光谱数据库。
