Port construction at McArthur River Mine in the western Gulf of Carpentaria, Australia, required the dredging of an access channel through a prolific seagrass community. A 4 km by 60 m channel dredged to 5 m depth removed 18.95ha of intertidal and shallow subtidal seagrass. Dredge spoil was pumped onshore to settle in multiple ponds before the decant water returned to the gulf. Quantitative surveys of the seagrass community surrounding the channel using a Before After Control Impact Repeated measures (BACIR) experiment were conducted to investigate the effect of the channel construction on the seagrass community.

航道疏浚对澳大利亚卡奔塔利亚湾海草群落的影响

澳大利亚卡奔塔利亚湾西部麦克阿瑟河矿的港口建设需要疏浚一条穿过丰富的海草群落的通道。一条 4 km x 60 m 的航道疏浚至 5 m 深，清除了 18.95 公顷的潮间带和浅潮下海草。在倾析水返回海湾之前，疏浚弃土被泵送到岸上，沉淀在多个池塘中。采用控制前后影响重复测量（BACIR）实验对航道周围的海草群落进行定量调查，以研究航道建设对海草群落的影响。
