“…Particularly under conditions of climate change and coastal urbanization, the importance of monitoring Water Surface Temperature (WST) cannot be understated, as many aspects of estuarine management and restoration are dependent on good, spatially referenced, WST data (Preston, 2004). The temperature of shallow estuaries fluctuate widely between summer and winter, but the spatial pattern of this oscillation is complex (Cowan & Boynton, 1996;Kaushal et al, 2010;Paaijmans et al, 2008) due to tidal cycles, freshwater discharge patterns, and industrial use of water during power generation (Demars & Manson, 2013;Takeshige, Takahashi, Nakata, & Kimura, 2013;Tan & Cherkauer, 2013). These multiple influences on water temperature operate across a range of temporal and spatial scales, suggesting that an ideal monitoring network must be both spatially dense and extensive, and operate continuously over time.…”

“…However, in situ measurement is expensive and time consuming to deploy over large water bodies. Thermal infrared water leaving radiance acquired from remote sensing sensors has been successfully employed to retrieve WST (Alcântara et al, 2010;Handcock et al, 2006;Hedger et al, 2007;Politi, Cutler, & Rowan, 2012;Takeshige et al, 2013;Tan & Cherkauer, 2013), however, in coastal systems the large pixel sizes of most sensors with appropriate temporal resolution is too large to effectively study near-shore spatial and temporal patterns. In recent years, there have been several applications of Landsat-class data to coastal WST, which significantly reduces the impact of shoreline contamination on the analysis of WST (Fisher & Mustard, 2004;Hook et al, 2004;Lamaro, Mariñelarena, Torrusio, & Sala, 2013;Sobrino, Jimenez-Munoz, & Paolini, 2004;Wloczyk, Richter, Borg, & Neubert, 2006).…”

“…3). In addition, Takeshige et al (2013a) reported that the wind speed in Omura Bay has tended to decrease in recent years in response to the lowering of the East Asian monsoon index. This weakened wind speed may also contribute to more stagnant conditions in this bay, resulting in the development of oxygen-restricted water.…”

Variations in the fish community structure in Omura Bay, an enclosed bay in the East China Sea, were investigated using long-term fishery landing data over the past five decades . We confirmed that the fish community structure in Omura Bay showed three conspicuous regimes during the study period. Anchovies dominated in the pelagic domain with abundant and various demersal fish species in the first phase (1965)(1966)(1967)(1968)(1969)(1970)(1971)(1972)(1973)(1974)(1975)(1976)(1977)(1978). Demersal fish declined remarkably with the dominance of sardines in the pelagic domain during the second phase (1979)(1980)(1981)(1982)(1983)(1984)(1985)(1986)(1987), and the fish community was simplified with the return of anchovies and no recovery of demersal fish in the third phase (1988)(1989)(1990)(1991)(1992)(1993)(1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004)(2005)(2006). These changes were significantly related with periodic largescale climate changes and cumulative regional-scale human impacts. The replacement of sardine/anchovy caused by a climate regime shift in the North Pacific contributed to the fish community regime shifts in Omura Bay. Moreover, habitat degradation such as depletion of dissolved oxygen combined with climate-induced changes in food web systems resulted in a rapid reduction in demersal fish. Contraction of the habitat volume due to an increase in oxygen-restricted water simplified the fish community structure and eventually reduced fishery landings in Omura Bay. These findings demonstrate that long-term fish community responses to largescale climate changes and regional-scale human impacts can be observed in a coastal enclosed bay, providing useful information for fisheries management in areas with climate and human-induced changes.

The climatology and linear trend of seasonal water temperature and heat budget in a semienclosed sea connected to the Kuroshio region (Seto Inland Sea: SIS) are investigated by constructing and analyzing a gridded data set of water temperature, salinity, and air‐sea heat fluxes. In the SIS, winter‐time water temperature and ocean heat content (OHC) showed a significant increasing trend while those in summer‐time exhibited no significant change. By analyzing the heat budget between the tendency of ocean heat content ∂OHC/∂t and air‐sea net heat flux Qnet, the driving factor of the winter‐time warming trend in the SIS was identified as autumn Qnet, while the unchanged summer‐time OHC is mainly due to decreased spring‐time oceanic heat transport to the SIS from the Kuroshio region. In addition, we showed that the decreased spring‐time heat transport could have been induced by upwelling due to wind curl and wind speed in the shelf‐slope region, heat transport by the Kuroshio south of Shikoku Island, and freshwater input to the SIS from rivers. The importance of both oceanic and atmospheric forcing mechanisms for explaining variation in the water temperature in coastal areas is demonstrated.
