Particulate Organic Carbon and Suspended Particle Size Spectra in the Southern Taiwan Strait during Summer

Abstract

本论文研究台湾海峡南部颗粒有机碳(POC)、总悬浮颗粒物(TSM)、颗粒氮(PN)及颗粒物体积浓度的时间和空间分布,捕捉对上升流事件的逐日响应,分析夏季航次POC与TSM和叶绿素a(Chl-a)之间的关系及其变化规律,分析悬浮颗粒物粒径谱中Sheldon谱图和正态化谱图的特征,探讨将现场激光粒度仪作为POC赋存生态系统结构的高分辨率现场探测方法的可能性。 根据2004年夏季、2005年夏季和2006年夏季三个航次观测数据,表层POC含量的分布表现出近岸高、远岸低的特点,POC浓度的剖面分布存在由表层到底层逐渐降低、中层出现高值后再降低和下层出现了高值的三种类型,表层和次表层POC含量的高值区...The temporal and spatial distributions of particulate organic carbon (POC), total suspended matter (TSM) , particulate nitrogen (PN) and particle volume concentration were studied in the southern Taiwan Strait. The day-to-day concentrations of POC and TSM were observed in upwelling area. The relationship and variety regulation among POC, TSM and Chl-a, and character of Sheldon size spectra and nor...学位:理学硕士院系专业:海洋与环境学院环境科学与工程系_环境科学学号:20043402
