碩士 / 國立中山大學 / 海洋科學系研究所 / 104 / Suspended particulate matter in coastal water includes abiotic (mineral) and biotic particles,and terrestrial and marine particles which can be defined by its composition. Mineral particles are composed of mineral material derived from the weathering of crustal material, and are mainly consist of quratz and other primary aluminosilicate minerals. The biogenic component is generated in situ or externally by biological process, and includes microorganisms, plankton, fecal matter and marine and terrestrial plant debris.
Mineral and biogenic particles can not be easily separated during sampling, so Al, which was regarding as a tracer of terrestrial lithogenic particles, is usedto calculate the percentages of mineral/biogenic contribution in suspended particles. In order to understand the contribution of marine or terrestrial sources, particulate organic carbon (POC), C/N ratio, chlorophyll aand phaeopigment a, were determined in size-fractionated coastal particles to characterized various sources of particles in coastal seawaters off Taiwan. Seasonal variation was accessed with samples collected on May and Octocber, 2012.
In this study, I found that the concentrations of suspended particulate matter (SPM), chlorophyll a and phaeopigment a in wet season are hgher than in dry season. Besides, there is no significant seasonal variation in the concentrations of Al.
A significant portion of suspended particles in coastal waters surrounding Taiwan are composed of marine particles, except for those stations near high discharge and suspended particulate matter in May 2012, which are composed of predominantly terrestrial particles.
