Water movements comprising "wave exposure" are an important characteristic of wave-swept rocky shores. Although biological sconsequenses of exposure have been intensively studied, the detailed mechanism through which exposure affects biological processes has received less attention. Here it is proposed to study one important and little understood aspect of water motion, the transport in the nearshore region of the larvae of bottom-dwelling species on wave-swept, rocky coasts. The following questions are asked: 1. How are larvae affected by flow on a scale of millimeters to centimeters? These flows may have important consequences for the release as well as the retention and settlement of larvae. 2. What predictable, larger-scale flows transport larvae offshore, and what flows bring them back? 3. What are the direction(s) and time course(s) of larval transport in the nearshore? 4. How do the behaviors of larvae affect their transport? Experiments will be conducted on the wave-swept, rocky coast of Central California.

包含“波浪暴露”的水运动是波浪冲刷岩石海岸的一个重要特征。虽然暴露的生物学后果已得到深入研究，但暴露影响生物过程的详细机制却受到较少关注。在这里，我们提出研究水运动的一个重要而鲜为人知的方面，即在波浪冲刷的岩石海岸上的底栖物种的幼虫在近岸地区的运输。问以下问题：1。在毫米到厘米的尺度上，水流对幼虫有什么影响？这些水流可能对幼虫的释放、滞留和沉降产生重要影响。2. 哪些可预测的、更大规模的水流将幼虫运至近海，哪些水流又将它们带回来？3. 幼虫在近岸的运输方向和时间路线是什么？4. 幼虫的行为如何影响它们的运输？实验将在加州中部被海浪冲刷的岩石海岸进行。
