“…A ''frontal HAB'' between Pearl River discharge water and the South China Sea water was observed in the northern South China Sea (Tang et al, 2003b). In the present observation, algal bloom occurred and moved along with the frontal waters between the Luanhe River discharge plume and the coastal current (Fig.…”

“…In the South China Sea, occurrences of HABs are closely related to water temperature, especially in the waters adjacent to Daya Bay [37] [38]. Relevant studies showed that when approaching the power station, the water temperature increases and could create conditions favorable for algal growth [6] [36].…”

The increase of water temperature, due to thermal discharges from two nuclear power stations, was one of the most significant environmental changes since 1982 in the Daya Bay, located in the north of the South China Sea. This study investigates the long-term (1982-2012) environmental changes in Daya Bay in response to the increase of water temperature, via comprehensively interpreting and analyzing both satellite and in situ observations along with previous data. The results show that: 1) salinity, dissolved oxygen (DO), chemical oxygen demand (COD) and nutrients had been enhanced after the thermal discharges started in 1994; 2) the concentration of Chl-a increased while the net-phytoplankton abundance decreased; 3) diversity of the phytoplankton community had decreased; 4) fishery production had declined; and 5) frequency of Harmful Algal Bloom occurrence had increased. Satellite images show clearly that a thermal plume from the power stations extended toward the interior of Daya Bay, and that surface temperature of the seawater increased as one approached the power stations. The analysis suggests that the thermal water discharged from the two power stations was a driver of the ecosystem's change in Daya Bay. Several factors, including nutrients, salinity, DO, and COD, varied according to the increase of water temperature. These factors affected the water quality, Chl-a, and phytoplankton in the short term and impaired aquatic organisms and the whole ecosystem in the long term.

“…Third, nutrient-rich water from Yangtze River meets with the warm water from Taiwan Strait to form a convergence zone that is usually favorable for the phytoplankton growth and HAB occurrences (Tang et al, 2003;Zhou et al, 2003).…”

“…Harmful Algal blooms (HABs) are a serious marine problem and have increased in frequency, intensity, and geographic extent worldwide; this increase is not only a threat to marine aquaculture throughout the world but also a threat to human health (Anderson, 1997;Tang et al, 2003Tang et al, , 2004aTang et al, , 2005. The first documented HAB event in China was caused by Noctiluca scintillans and Skeletonema costatum in Zhejiang coastal waters in 1933.…”

The occurrences of harmful algal blooms (HABs), in terms of frequency and area in the Chinese coastal waters, have been increasing since 1980s and caused considerable economic losses. In the present study, we have analyzed spatial and seasonal characteristics of HAB events in the southern Yellow Sea and East China Sea along Chinese coast from 1933 to 2004. With a total 435 HAB records, the most frequent HAB occurrence area (FHA) is off the Yangtze River mouth and another two FHA areas are located south of the Yangtze River estuary along about isobaths of 30-60 m coastal water in the East China Sea.
