英文摘要Iron (Fe) is an essential micronutrient for the growth of marine phytoplankton and a key factor to affect marine primary productivity. Dissolved reactive iron (DRFe), one of the main components of dissolved Fe, is closely related to the absorption of marine organisms. In this paper, the variation characteristics of DRFe concentration at high tide and low tide were studied by continuous monitoring at Yellow Sea coast for 30 days. The effect of tidal action on DRFe concentration was analyzed, and the relationship between DRFe concentration and physicochemical parameters of seawater was further discussed. This study showed that the DRFe concentration at high tide was slightly higher than that at low tide, with a maximum concentration difference of 2.32 nmol/L and a minimum concentration difference of 0.44 nmol/L. The monthly variation of DRFe concentration was not significant in May, ranging from 4.06 to 8.34 nmol/L, with an average concentration of 5.70 nmol/L. DRFe concentrations were higher at the beginning of the month and then gradually declined. The increase of seawater temperature will promote the growth of phytoplankton and increase of chlorophyll a content, which will accelerate the consumption of DRFe.
中文摘要铁(Fe)是海洋浮游植物生长必需的微量元素,也是影响海洋初级生产力的关键因素。溶解活性态铁(DRFe)是溶解态Fe的主要组成之一,与海洋生物体的吸收密切相关。本文通过对黄海近岸海水30天定点连续分析监测,研究了黄海近岸海水中DRFe在高、低潮时的浓度变化特征,分析监测了潮汐作用对DRFe的影响,并探讨了DRFe与海水理化参数间的关系。研究表明:高潮时DRFe浓度略高于低潮,最大浓度差为2.32 nmol/L,最小浓度差为0.44 nmol/L;DRFe浓度月变化差异不大,其范围为4.06~8.34 nmol/L,平均浓度为5.70 nmol/L;5月初,DRFe浓度较高,随后逐渐下降;海水温度升高会促进浮游植物生长,致使Chl a含量增加,同时加速DRFe的消耗。
