Abstract

The primary production (PP) by phytoplankton in marine ecosystems is essential for carbon cycling and fueling food webs. Hence, estimating the PP in the territorial sea of each country is a necessary step to achieving carbon neutrality. To estimate the PP in the territorial sea of the Republic of Korea from 2005 to 2021, we analyzed various physiochemical parameters, such as sea surface temperature (SST), Secchi depth, and concentrations of chlorophyll-a and nutrients in the seas of five regions, including the East Sea, West Sea, western South Sea, eastern South Sea, and the waters off Jeju Island. During the 17-year study period, the SST tended to increase, while the nutrient concentrations declined, except in the Jeju area. Overall, the PP did not show a specific temporal trend, but daily PP in the western South Sea was the highest among the five regions. Moreover, the maximum PP in the Korean territorial waters (76,450 km2 ) was estimated at 11,227 Gg C y-1, which accounts for 0.03% of the global PP. The results may give insights into a better understanding of the PP, further resource utilization, and environmental sustainability in the studied region.

大韩民国领海浮游植物的初级生产

海洋生态系统中浮游植物的初级生产(PP)对碳循环和食物网至关重要。因此，估算每个国家领海的PP是实现碳中和的必要步骤。为了估算2005 - 2021年韩国领海PP，我们分析了东海、西海、南海西部、南海东部和济州岛海域5个区域的海表温度、Secchi深度、叶绿素-a浓度和营养物浓度等理化参数。在17年的研究期间，除济州地区外，海温呈上升趋势，而营养物浓度呈下降趋势。总体而言，南海西部的日PP在5个区域中最高，但没有表现出特定的时间趋势。此外，韩国领海(76,450 km2)的最大PP估计为11,227 Gg C y-1，占全球PP的0.03%。这一结果可能有助于更好地了解研究区域的PP，进一步的资源利用和环境可持续性。
