Long Term Characterization of the Tidal Band Internal Wave Climate on the Central California Coast

0220566 Winant利用矿产管理署圣巴巴拉海峡-圣玛丽亚盆地研究的10年数据，PI将描述当地的内部潮汐制度。拟议研究的主要目标将是确定加州中部地区潮汐带运动的结构，计算与内部潮汐相关的能量学，并确定可能的耗散和混合点。将根据当地平均流量和层结的年周期，编制和评估主要内部潮汐特性的年平均时间序列。将确定平均流场、层结和气象中的间歇性事件对内部潮汐结构的影响。将查明厄尔尼诺现象和其他由气象和海洋条件引起的年际变化所对应的年平均周期的偏差。利用这项研究产生的信息，将有可能定量评估研究地理区域和美国西部类似的沿海陆架地区内潮汐对水质和资源管理问题的影响。

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.
