A simple and effective algorithm to retrieve total suspended matter from GOCI data in Hangzhou Bay, China.

Summary: Hangzhou Bay in China is famous for its muddy, turbulent waters. Strong tides and river currents constantly stir up sediment, making the water extremely cloudy. This "Total Suspended Matter" (TSM) changes so fast that it is difficult to monitor using standard methods. Researchers have developed a new, simple, and effective computer formula (algorithm) that uses data from the GOCI satellite—a "camera" in space that watches the ocean. This new method allows scientists to accurately map these extreme sediment levels from space, helping to better understand the health and movement of the bay's waters without needing a boat for every measurement.
