Monitoring Variation in Sea Surface Temperature in the Nakdong River Estuary, Korea, Using Multiple Satellite Images. Journal of Coastal Research. Special Issue No. 90, pp. 183-189. http://dx.doi.org/10.2112/SI90-022.1. Click Sea surface temperatures (SSTs) of the coastal waters around Nakdong River, Korea, were analyzed using data from August during 2001~2017 from Landsat (a and b taken on 7 August 2015 and 25 August 2016, respectively) and from (c) annual and (d) monthly data of the Moderate Resolution Imaging Spectroradiometer (MODIS) during 2000~2018. SST data derived from Landsat and MODIS images were verified using in-situ data (Points 1-4 in Figure a). SST values derived from MODIS data were consistent with the in-situ data (R2 = 0.63), whereas Landsat-derived SST values were moderately correlated with in-situ data (R2 = 0.44). The mean annual SST over 18 years was 21.7 °C. The coldest temperatures were recorded in 2001, and the warmest were recorded in 2016. SSTs were higher during the summer than in the winter, mainly because of higher air temperatures in summer. Across all years, March was the coldest month, with a mean SST of 14.4 °C, whereas August was the warmest month at 28 °C. Continue rading...
