“…We expect that thermal discharge may affect the species composition of phytoplankton communities between the outlet and intake regions, as reported by Poornima et al (2005) and Chuang et al (2009). Similarly, Li et al (2011) found that the contribution of diatoms and dinoflagellates to the total phytoplankton population showed significant correlation with temperature, negative for diatoms, while positive for dinoflagellates.…”

“…Patrick (1969) reported that the dominant diatom genera, Nitzschia, Navicula, and Achnanthes, in the periphyton of the outlet region were similar to those of freshwater periphyton that were tolerant to high temperatures. By contrast, the diatoms, Mastogloia, Diploneis, Cocconeis, and Epithemia, did not tolerate high temperatures and were absent from the outlet region but occurred only in the intake region of NPP II (Chuang et al 2009). Similar phenomena were also noted by the present study.…”

“…Although we did not have sufficient temperature data on the NPP outlet, temperature records for NPP II outlet and intake during 2001 -2003 were available from two previous studies. Chuang et al (2009) measured the outlet and intake seawater temperature for NPP II trimonthly and found that the average temperature in the outlet was usually 8 -11°C higher than that in the intake. Shiah et al (2006) reported a difference of about 10°C between the outlet (higher) and intake (lower) waters of this power plant.…”

“…Shiah et al (2005) explored planktonic and ecosystem responses to thermal effluents from NPP II and suggested that the phytoplankton were more vulnerable than heterotrophs to thermal stress in temperature manipulation experiments. Similarly, chlorination caused a greater reduction in phytoplankton productivity than in periphyton productivity compared to elevated seawater temperatures near NPP II (Chuang et al 2009). The present study was carried out in the coastal waters off NNP I and NNP II in northern Taiwan.…”

“…The potential impact of thermal discharge from a coastal power plant cooling system on marine organisms and their ecosystem has been studied extensively in the last decades, e.g., bacteria (Choi et al 2002;Shiah et al 2006), phytoplankton (Martínez-Arroyo et al 2000;Poornima et al 2006;Chuang et al 2009), zooplankton (Yang et al 2002;Jiang et al 2009), crab (Suresh et al 1995), fish (Teixeira et al 2009), and sedentary organisms (Lardicci et al 1999;Teixeira et al 2009). Most recent impact studies on phytoplankton focused mainly on the effects of elevated seawater temperature and residual chlorine on the biomass and productivity Rajadurai et al 2005;Chuang et al 2009). Li et al (2011) reported that the nuclear power plant thermal discharge in the subtropical Daya Bay in China strongly influenced the phytoplankton community.…”

This study investigates the seasonal and spatial differences in phytoplankton communities in the coastal waters off two nuclear power plants in northern Taiwan in 2009. We identified 144 phytoplankton taxa in our samples, including 127 diatoms, 16 dinoflagellates, and one cyanobacteria. Four diatoms, namely, Thalassionema nitzschioides (T. nitzschioides), Pseudo-nitzschia delicatissima (P. delicatissima), Paralia sulcate (P. sulcata), and Chaetoceros curvisetus (C. curvisetus) and one dinoflagellate Prorocentrum micans (P. micans) were predominant during the study period. Clear seasonal and spatial differences in phytoplankton abundance and species composition were evident in the study area. Generally, a higher mean phytoplankton abundance was observed in the waters off the First Nuclear Power Plant (NPP I) than at the Second Nuclear Power Plant (NPP II). The phytoplankton abundance was usually high in the coastal waters during warm periods and in the offshore waters in winter. The phytoplankton species composition was different in the NPP intake and outlet. An abundant phytoplankton increase in the outlet was frequently detected, probably due to the difference in phytoplankton species suitability to thermal stress. Our results suggest that thermal discharge may affect the phytoplankton communities by altering its species composition within a restricted area close to the NPP. This study provides basic knowledge on phytoplankton distribution patterns, essential information required to further understand the ecological impact caused by thermal effluents.

Net ecosystem exchange (NEE) of tidal brackish wetlands in urban areas is largely unknown, albeit it is an important ecosystem service. High carbon dioxide (CO 2 ) uptake of estuaries can potentially be achieved by creating conditions that foster CO 2 uptake and sequestration. Thus, this study sought to assess NEE in a mesohaline tidal urban wetland that has been restored and determine the biophysical drivers of NEE in order to investigate uptake strength and drivers thereof. Beginning in 2009, NEE was measured using the eddy covariance technique in a restored urban estuarine wetland. Maximum NEE rates observed were À30 μmol m À2 s À1 under high light conditions in the summer. Monthly mean NEE showed this ecosystem to be a CO 2 source in the winter, but a CO 2 sink in summer. Conditional Granger causality showed the influence of net radiation on half daily to biweekly timescales on NEE and the influence of water level at half daily time scales. The overall productivity of this wetland is within the expected range of tidal brackish marshes and it was a sink for atmospheric CO 2 in two out of the 3 years of this study and had a continued increase over the study period.
