鈥淨atar in the Arabian/Persian Gulf is one of the countries with the fastest economic growth and relies on seawater as its most important water source. The country鈥檚 fast development caused concerns about its coastal water quality because these waters are under the pressure of harmful algal blooms, ocean warming, hypoxia, and coastal pollution. The difficulty in monitoring water quality changes is due to the lack of sufficient field measurements across political boundaries. We overcome this challenge by using the state-of-the-art satellite remote sensing, which provided data for over two decades. We examined spatial/seasonal variations and assessed long-term trends of water-column chlorophyll concentration, turbidity, water clarity, temperature, and surface algae scums. While most of these water quality parameters showed no dramatic long-term trends, water temperature showed much higher warming rate than the adjacent seas such as the Arabian Sea and Red Sea. Whether such a trend will continue in the future to favor algal blooms requires a long-term monitoring program. We will continue to assess the coastal water quality around Qatar and the Arabian/Persian Gulf. Meanwhile, in near real-time with daily updates.鈥�
