MacCready0099058A three-pronged field effort is proposed to study the generation, release, and dissipation of tidally generated sidewall eddies in a fjord. The deep (stratified) water adjacent to the headland at which the eddy is generated precludes immediate dissipation by bottom friction. Laboratory experiments suggest that the long lifetime of the eddy promotes different characteristic flow fields than observed in shallower environments. This hypothesis will be tested.

MacCready 0099058A三管齐下的现场工作，提出了研究潮汐产生的侧壁涡在峡湾中的产生，释放和消散。 靠近岬角的深水（分层）阻止了底摩擦力的立即消散，在岬角处产生涡流。 实验室实验表明，长寿命的涡流促进不同的特征流场比在较浅的环境中观察到的。 这一假设将得到检验。
