基于FerryBox的渤海海峡水质低成本长期自动监测
Long-term and low-cost automatic monitoring of water qual-ity in the Bohai Strait using FerryBox
摘要
Abstract
FerryBox is an automated, real-time aquatic ecosystem monitoring system that has many advantages such as multiple parameters, low maintenance, low cost, wide monitoring coverage, and strong sustainability. The Fer-ryBox that was installed in a cargo ship that frequently shuttled between Yantai and Dalian from October 2015 to July 2016 achieved a ten-month low-cost water quality automatic monitoring of the Bohai Strait. The monitoring results showed that the spatial and temporal distribution of water environmental factors between the northern and southern Bohai Strait had significant differences. While the surface turbidity and surface pH in the southern Bohai Strait were higher than that in the central and northern sea area in autumn, the surface temperature, surface salinity, and surface turbidity of the northern Bohai Strait were higher than that in the southern sea area in winter; in addition, the chlorophyll-a concentration of the central and southern Bohai Strait was higher than that of the northern sea area after the beginning of spring. Monsoon, warm current of the Yellow Sea, and the Bohai Sea circulation were the main reasons for the differences in the water environmental factors distribution in the Bohai Strait. The monitoring results of the nutrients in the Bohai Strait in the spring and summer of 2016 showed that the temporal and spatial distribution of nutrients in the Bohai strait had obvious seasonal and regional characteristics. The nutrient content was high in early spring and late summer in the temporal variation, and the nutrient content of both sides of the Bohai Strait was higher than that of the central sea area in the spatial distribution. Decomposition of particles in a submarine, cold water mass, algae reproduction, surface runoff, and the Bohai Sea circulation were the important factors that affected the temporal and spatial distribution of nutrients in the Bohai Strait during spring and summer. The nutrients that limited the phyto-plankton growth were silicon and phosphorus in spring and solely phosphorus in summer.关键词
