“…2). The maximum water temperatures in the summer off the Wando coast were low compared with those off the Tongyeong coast, which is well known for oyster culturing, and this temperature difference might be attributed to a strong tidal front around Jindo island (Jung 2001;Moon et al 2006;Oh et al 2008). Precipitation can influence the success of oysters (Calvo et al 1999;Soletchnik et al 2007), and the input of freshwater can increase PP in coastal waters by the input of land-driven nutrient into the coastal region (Choi et al 1997).…”

To establish a comprehensive management strategy, as part of the optimization of cultural practice for an oyster rack culture system, we used a numerical model to estimate the primary production in the waters on the eastern coast of Wando island, South Korea. The estimated primary production ranged from 17.12 to 1052.55 mgC m −2 day −1 (204.22 ± 224.75 mgC m −2 day −1 in average). Except for the times of peak phytoplankton blooms, the estimated primary production (PP) was consistently under 200 mgC m −2 day −1 , which is more similar to the value of PP measured off the western coast of South Korea than the southern coast. No clear relationship was observed between nitrogen content and rainfall with the exception of heavy rainfall events, indicating that precipitation might not be the main source of nutrients in these waters. No clear influence was observed from Doam tidal discharge, located 24 km north from these waters due to main tide comes in this area from the channel between Gunwe-myeon in Wando island and Pukpyeong-myeon in Haenam-gun. Because of the shallow water depth and strong tidal current, resuspension of sediments, which causes an input of nitrogen into the system, could be easily caused by even mild wind and the infrequent passing of ships. Microscopic examination of the phytoplankton composition showed additional contribution of benthic species such as Paralia sulcata into the waters, which increase the productivity of oyster farms in the waters. The availability of nitrate and phosphate for primary production was temporarily limited throughout most of the spring and autumn blooming season.

“…In summer, the water temperature, salinity, and dissolved oxygen are 15. 19°C-24.97°C, 32.41-34.04 psu, and 7.40-9.14 mg/L, respectively (Oh et al, 2008). The area southwest of Nohwado, which is located to the southwest of Wando, is a littoral zone in a tidal flat along a 12-mdeep channel flowing northwest-southeast between Bogildo and Nohwado ( Fig.…”

“…우리나라 연안에서 발생하는 냉수대는 남서 연안 해역의 경우 주로 조석에 의해 발생하며 (Oh et al, 2008), 동해 남부 연안 해역 에서는 남서풍에 의해 냉수대가 발생한다 (Kim et al, 2010). 냉수 대는 주변보다 급격하게 낮아진 수온으로 인해 어류를 포함하는 다양한 해양 생물에 영향을 미치며, 특히 저수온과 함께 표층으로 공급된 영양염(nutrients)은 식물플랑크톤 군집에도 크게 영향을 미 친다 (Herrera and Escribano, 2006).…”

냉수대 발생 전·후의 해양 환경과 식물플랑크톤 군집 구조 및 크기를 파악을 위해 여름철 빈번하게 냉수대가 발 생되는 동해 남부 해역(울산 정자~부산일광In order to understand environment condition and phytoplankton community before and after coastal upwelling, the influences of upwelling events on phytoplankton community were studied at 18 stations located the Southern part of East Sea, Korea from May to August 2013. The surface water masses showed low temperature and high salinity due to upwelling events at coastal stations (A1, B1, C1). Correlation between temperature and nutrients (DIP, p<0.01; DIN, p<0.01; silicate, p<0.01) was significantly negative. This result could be explained that nutrients were supplied to surface water by the upwelling of bottom water. Phytoplankton communities were composed of 186 species. Phytoplankton abundance were relatively high in May (C1, 726×103 cells L
