Ocean Radar - Rottnest shelf site - Sea water velocity - Delayed mode

The Rottnest Shelf (ROT) HF ocean radar system covers an area which includes Rottnest Island and the Perth Canyon to the north-west. The Perth Canyon has the highest marine biodiversity in the region with whale and fish aggregations, and high primary and secondary productions which are controlled by the physical oceanographic processes. Combined with the dynamics of the Perth Canyon is the dominant Leeuwin Current which produces a wake on the leeward side of Rottnest Island. This is a topographically induced up-welling and associated primary and secondary productivity. The region is influ...罗特内斯特陆架（Rottnest Shelf，ROT）高频（HF）海洋雷达系统的覆盖区域包含罗特内斯特岛以及西北方向的珀斯峡谷。珀斯峡谷是该区域海洋生物多样性最高的区域，存在鲸类与鱼类集群现象，其较高的初级与次级生产力受物理海洋过程调控。与珀斯峡谷的动力特征相伴的是占据主导地位的勒温洋流（Leeuwin Current），该洋流会在罗特内斯特岛的背风侧形成尾流。该尾流属于地形诱导上升流，并伴随相应的初级与次级生产力。该区域受
