Water Flow in Seagrass Ecosystems - Hydrodynamic environment of seagrass meadows

The hydrodynamic environment within the seagrass canopy of Amphibolis griffithii, Posidonia australis, Posidonia sinuosa and mixed Posidonia beds was studied, and compared with a bare sand site (See thumbnail). Electronic current meters developed by the author (Chapter 2 of thesis) was used to measure water velocity profiles.
In addition, the hydrodynamic regimes of sheltered and exposed Posidonia sinuosa sites were studied, as well as sediment size fraction distribution within a dense Posidonia sinuosa meadow. These studies were undertaken in Shoalwater Bay located south of Perth, Western Australia.

本研究针对格里菲思两栖草（Amphibolis griffithii）、澳洲波喜荡草（Posidonia australis）、波叶波喜荡草（Posidonia sinuosa）以及混生波喜荡草床的海草冠层内水动力环境展开调查，并与裸沙站位进行对照（详见缩略图）。本研究采用作者自研的电子海流计（参见论文第二章）测量流速剖面。此外，本研究还调查了遮蔽型与开阔型波叶波喜荡草站位的水动力状况，以及密生波叶波喜荡草甸内的沉积物粒级分布。所有研究工作均在西澳大利亚州珀斯以南的肖尔沃特湾（Shoalwater Bay）开展。
