Generally speaking, the higher the ratio of diatoms to diflagellate, the better the water quality should be
Seaweed, also known as phytoplankton, plays a very important role in marine ecosystems
Recently, a research team led by Professor Liu analyzed data from 2000 to 2017 including temperature, seawater nutrients and oxygen content
The team established a number of statistical models to analyze the relevant data and found that the growth of diatoms is not necessarily based on the improvement of water quality, but due to changes in the nutrient composition of the seawater of the Pearl River Estuary, including the rapid nitrate content caused by various human activities.
Although the amount of seaweed in high latitudes and offshore areas has been extensively studied, there are very few studies on highly urbanized subtropical areas such as the Pearl River Estuary and tropical coastal areas
Professor Liu said: "Red tides/algae blooms are a major environmental issue.
