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.

包括“波浪暴露”的水运动是一个重要的 具有波浪冲刷岩石海岸的特点。 虽然生物 暴露的后果已经被深入研究， 暴露影响生物学特性的详细机制 过程受到的关注较少。 在这里，建议研究 水运动的一个重要而又鲜为人知的方面， 底栖的幼虫在近岸区域的迁移 生活在海浪冲刷的岩石海岸上。 以下问题 问：1. 幼虫是如何受到流动的影响， 毫米到厘米 这些流动可能具有重要的 释放以及保留和解决的后果 的幼虫。 2. 什么是可预测的，更大规模的流动运输 是什么水流把它们带回来的 3. 有哪些 幼虫运输的方向和时间进程 近岸？ 4. 幼虫的行为如何影响它们的 交通工具？ 实验将在波浪扫过的岩石上进行， 位于中加州海岸。
