Collins 9811035 Repeated measurements will be conducted to study the effect of the 1997/98 El Nino event on the hydrography and velocity fields off Central California. The observations will enhance the temporal coverage of quarterly cruises (1/98, 5/98, 7/98 and 11/98) funded by the Naval Postgraduate School and the Naval Oceanographic Office to monthly in the spring and bi-monthly in the summer. The main objectives of the work are to determine whether the observed warming of the surface waters is due to onshore advection of fresh water or poleward flow of saltier water and whether the oceanographic response is locally or remotely forced. The proposed measurements would complement similar projects scheduled to occupy off-shore transects from Baja California to Washington State. The CalCOFI (California Cooperative Oceanic Fisheries) line #67 that the PI proposes to sample in the Spring/Summer of 1998 has been extensively sampled since 1949 which would provide an accurate description of the climatology of the eastern boundary current system as well as comparisons of the oceanic response for the most recent El Ninos. The processed data will be made available on a web page for use by other scientists.

柯林斯9811035将进行重复测量，以研究1997/98年厄尔尼诺事件对加州中部海域水文和速度场的影响。 这些观测将扩大由海军研究生院和海军海洋学办公室资助的季度巡航（1998年1月、1998年5月、1998年7月和1998年11月）的时间范围，使之在春季每月一次，在夏季每两个月一次。 这项工作的主要目标是确定观测到的表层沃茨变暖是由于淡水向岸平流还是咸水向极流动，以及海洋学的反应是本地还是远程强迫的。拟议的测量将补充计划占用从下加利福尼亚到华盛顿州的离岸样带的类似项目。PI提议在1998年春季/夏季采样的CalCOFI（加州合作海洋渔业）#67线自1949年以来已进行了广泛采样，这将提供东部边界流系统气候学的准确描述以及海洋的比较最近厄尔尼诺现象的反应。处理后的数据将在网页上公布，供其他科学家使用。
