Wave induced flow and sediment transport are dominant processes on the spatial and temporal scales of benthic organism behavior, feeding and growth. The responses of marine benthic organisms to waves have been investigated via coupled field and laboratory observations and tests of "null-effect" hypotheses. It has been determined that both sediment microorganisms and macrofaunal consumers can respond to oscillatory flow and sediment transport on short time scales. Using field and laboratory experimentation, the effects of oscillatory flows on the feeding biology of intertidal and shelf invertebrates will be studied. Many of the experimental tests will utilize a uniquely constructed oscillatory water tunnel, which have future benefits in the study of the adaptations of benthic animals to their physical environments.

波浪诱导的水流和泥沙输移是底栖生物行为、摄食和生长的时空尺度上的主导过程。通过野外和实验室的耦合观测和“零效应”假设的检验，研究了海洋底栖生物对波浪的响应。已经确定，沉积物微生物和大型动物消费者都可以在短时间尺度上对振荡水流和泥沙输移做出响应。通过野外和实验室实验，研究了振荡流对潮间带和陆架无脊椎动物摄食生物学的影响。许多实验测试将利用一种独特的振荡水洞，这在研究底栖动物对其物理环境的适应方面有未来的好处。
