海岬、岛屿和珊瑚礁产生复杂的三维二次流，导致物理和生物前沿。这些珊瑚礁和岬角附近的混合和扩散过程与公海中的这些过程有很大不同，为公海开发的经典对流扩散模型在海岸附近无效。地形产生的锋影响沉积物的分布，它们聚集了水媒卵、幼虫和浮游生物。这种聚集影响到底栖生物组合和中上层二级和三级捕食者的分布和密度。
Headlands, islands, and reefs generate complex three-dimensional secondary flows that result in physical and biological fronts. Mixing and diffusion processes near these reefs and headlands are quite different from these processes in the open sea, and classical advection-diffusion models that were developed for the open sea are not valid near shore. Topographically generated fronts affect the distribution of sediments, and they aggregate waterborne eggs, larvae, and plankton. This aggregation influences the distribution and density of benthic assemblages and of pelagic secondary and tertiary predators.
