We propose to test a hypothesis explaining that settlement and onshore transport rates of some Southern California nearshore invertebrates should decrease in El Ni¹o conditions. Species affected would be those depending on internal motions for onshore transport. The hypothesis links thermocline structure, larval vertical distribution, and onshore transport. To test the hypothesis' predictions, we propose a monitoring program off Southern California and Northern Baja California. The observational program includes (a) three cruises for assessing larval distribution, (b) weekly monitoring of barnacle settlement at four nearshore locations spread along 100 km of coastline, and (c) temperature monitoring with nearshore moorings at the same locations.

我们建议测试一个假设，解释解决和岸上运输率的一些南加州近岸无脊椎动物应减少厄尔尼诺条件。 受影响的物种将是那些依靠内部运动向岸上迁移的物种。 该假说将温跃层结构、幼虫垂直分布和向岸迁移联系起来。为了检验假设的预测，我们提出了一个监测计划关闭南加州和北方下加利福尼亚。 观测方案包括（a）三次评估幼虫分布的航行，（B）每周监测沿着100公里海岸线分布的四个近岸地点的藤壶定居情况，（c）在相同地点用近岸系泊装置监测温度。
