Potential Temporal and Spatial Trends of Oceanographic Conditions with the Bloom of <i<Ulva Prolifera</i< in the West of the Southern Yellow Sea

Based on National Oceanic and Atmospheric Administration/Advanced Very High-Resolution Radiometer (NOAA/AVHRR) remote sensing and Cross-Calibrated Multi-Platform (CCMP) wind field data from 2007 to 2019, oceanographic conditions are analysed, respectively, in the Source Area (SA) and Typical Bloom Area (TBA) of <i<Ulva prolifera</i< (<i<U. prolifera</i<) in the west of the Southern Yellow Sea (SYS) using Sea Surface Temperature (SST), Suspended Sediment Concentration (SSC) and Wind Speed over the years. The results indicate that the annual maximum SST Difference (SSTD) between <i<U. prolifera</i< SA and TBA is strongly consistent with the intensity of <i<U. prolifera</i<, and a high SST Warming Rate (WR) from May to July may constrain the <i<U. prolifera</i< blooms. The Taiwan Warm Current (TWC), crossing Yangtze River Estuary northward from March to April, leads to SST increasing in the SA and becomes a key trigger for the growth of <i<U. prolifera</i< in the early period. The amount of <i<U. prolifera</i< may decrease in the early period because of the lower light intensity with high SSC and turbidity in SA. The summer monsoon is one of determinants for the spread of <i<U. prolifera</i<, and the distribution of <i<U. prolifera</i< reaches its highest point with a higher mean wind speed in the TBA.
