Abstract:
      A soil circulation occurs in the south of Cheju Island in the spring. Nutrients and its influence on chlorophyll a (Chl a) around the circulations were studied from April 9 to May 6, 2007. Spring bloom with elevated concentrations of Chl a was observed during the investigation. High concentrations of phosphate, nitrate and silicate at 0.6, 12, and 8 mmol/m3, respectively, were detected. A low water temperature prevented the growth of phytoplankton. Chl a concentrations in the study area might be strongly associated with the high silicate concentration.
中文摘要:
      在春季济舟岛南部呈现出泥沙环流。围绕环流区域,本研究关注2007年4月9日至5月6日营养盐及其对叶绿素a浓度的影响。在研究期间,随着研究区域叶绿素a浓度的提高,观测到显著的春季水华现象。高浓度的磷酸盐、硝酸盐和硅酸盐含量分别达0.6、12及8 mmol/m3。同时,低水温阻止了浮游植物的生长,而叶绿素a浓度的分布可能与相应的硅酸盐浓度有关。
