SGER: Physical Oceanographic Conditions off Central California in 1998

将进行重复测量来研究1997/98年厄尔尼诺事件对加利福尼亚中部海域的水文和速度场的影响。由海军研究生院和海军海洋学办公室资助的季度巡航（1/ 98,5 / 98,7 /98和11/98）的时间覆盖范围将扩大到春季每月一次，夏季双月一次。这项工作的主要目的是确定观测到的地表水变暖是由于淡水在岸平流还是咸水向极地流动造成的，以及海洋学的反应是局地的还是远距离的强迫。拟议的测量将补充计划占用从下加利福尼亚州到华盛顿州的近海横断面的类似项目。自1949年以来，PI提议在1998年春夏取样的CalCOFI（加州海洋合作渔业）线#67已被广泛取样，这将提供对东部边界流系统气气学的准确描述，以及对最近厄尔尼诺现象的海洋响应的比较。处理后的数据将在一个网页上提供给其他科学家使用。

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.
