Detection and Trackign the Green and Golden-tide in the eastern Yellow Sea using Multi-Satellite Sensors

Abstract

Blooms of the floating green-tide in the Yellow Sea occurred every year since 2007. Recently, massive golden-tide caused by floating brown macroalgal Sargassum also founded. Green-tide species was identified to be the Ulva linza-prolifera complex, and golden-tide species was identified as Sargassum horneri. Floating macroalgae patches continuously moved by surface current and wind, direct investigation based on cruise alone is limited to understanding their wide distribution and movement. Recently, there have been attempts to trace the evolution and transport of macroalgal blooms using various satellite imageries. However, compared with the western Yellow Sea, there is a lack of research on the distribution and transport of floating macroalgal bloom in the eastern Yellow Sea. Therefore, aim of this research is to find the origin, distribution and transport route of floating macroalgal patches in the eastern Yellow Sea using multi-satellite sensors. Massive green-tide was found in the eastern Yellow Sea for the first time in 2008, and the satellite image traced back shows that it originated from the western Yellow Sea. In 2009 and 2011, large mass of green-tide also found in the eastern Yellow Sea, and its largest scale of any green-tide has been found in 2011. Floating green-tide in the eastern Yellow Sea had different route and scales each year but all macroalgal patches were supplied from the western Yellow Sea.
