GLOBEC Long-term Observation Program in the Marine Ecosystem of the Northern California CurrentBoth temporal and alongshore spatial variability are significant in all regions of the California Coastal Study (CCS). Alongshore differences can occur as a result of alongshore gradients in wind stress; changing bottom topography (in particular canyons and banks) and coastline irregularities; and buoyant inflow from rivers (in particular the Columbia River and the Strait of Juan de Fuca). As part of the GLOBEC NEP study, the specific objectives of this project are:1) to provide data on alongshore and temporal variability in the coastal ocean nearshore environment of the Pacific Northwest region on scales of hours to several years and2) in conjunction with other GLOBEC investigators, to determine dominant factors controlling alongshore and temporal variability in ocean water properties and currents.To fulfill these objectives the PIs will maintain moored arrays to measure currents and water properties at two locations, one off southern Oregon (Coos Bay); the other off the central Washington coast (Grays Harbor). With the addition of these two arrays, the GLOBEC field study will include an alongshore time series array sufficient to define large scale alongshore water property gradients and responses to forcing mechanisms. These installations will continue an already two year long time series at each site. In addition, an earlier 5 year time series (the longest on the West Coast shelf north of Point Conception) is available at the Coos Bay site. Thus, by the end of this project, the Coos Bay site would include 11 record years, the Washington site, six years. The data obtained will provide vital information to modeling studies of this area over the next decade.

在加利福尼亚海岸研究（CCS）的所有区域中，时间和沿岸空间变异都是显著的。由于风应力的沿岸梯度，可能会出现沿岸差异；改变底部地形（特别是峡谷和河岸）和不规则的海岸线；以及来自河流（特别是哥伦比亚河和胡安德富卡海峡）的浮力流入。作为GLOBEC NEP研究的一部分，该项目的具体目标是：1)提供太平洋西北地区沿海海洋近岸环境的沿岸和时间变化数据，以小时到几年为尺度；2)与其他GLOBEC研究人员合作，确定控制海水性质和洋流的沿岸和时间变化的主要因素。为了实现这些目标，pi将在两个地点维护系泊阵列，以测量电流和水的性质，一个在俄勒冈州南部（库斯湾）；另一个位于华盛顿中部海岸（格雷斯港）。有了这两个阵列，GLOBEC的现场研究将包括一个岸上时间序列阵列，足以定义大范围的沿岸水属性梯度和对强迫机制的响应。这些装置将继续在每个地点进行长达两年的时间序列。此外，在库斯湾站点可以获得更早的5年时间序列（在概念点以北的西海岸大陆架上最长）。因此，到这个项目结束时，库斯湾遗址将包括11年的记录，华盛顿遗址，6年。获得的数据将为未来十年该地区的建模研究提供重要信息。
