0220566 Winant Using 10 years of data from the Mineral Management Service's Santa Barbara Channel-Santa Maria Basin study, the PIs will characterize the local internal tide regime. The major objectives of the proposed study will be to identify the structure of tidal band motions in the central California region, calculate the energetics associated with the internal tide, and identify possible dissipation and mixing sites. Mean annual time series of the key internal tide properties will be developed and assessed in terms of the annual cycles of the local mean flow and stratification. The influence of intermittent events in the mean flow field, stratification and meteorology on the internal tide structure will be identified. Aberrations from the mean annual cycles corresponding to El Nino and other interannual induced changes in meteorology and ocean conditions will be identified. With the information generated by this study, it will be possible to quantitatively assess the effects of internal tides on water quality and resource management issues in the geographical region of study and in similar coastal shelf regions of the western United States.

0220566 Winant 使用矿物管理服务局圣巴巴拉海峡-圣玛丽亚盆地研究 10 年的数据，PI 将描述当地内潮汐状况的特征。 拟议研究的主要目标是确定加利福尼亚州中部地区潮汐带运动的结构，计算与内潮汐相关的能量，并确定可能的消散和混合地点。将根据当地平均流量和分层的年周期来开发和评估关键内潮汐特性的平均年时间序列。将识别平均流场、层结和气象中的间歇性事件对内潮结构的影响。将确定与厄尔尼诺现象和其他年际引起的气象和海洋条件变化相对应的平均年周期的偏差。利用本研究产生的信息，将有可能定量评估内潮对研究地理区域和美国西部类似沿海陆架区域的水质和资源管理问题的影响。
