Coastal Upwelling Along the Western Americas: Past, Presentand Future

9633173 vanGreen 该奖项将支持PI访问墨西哥和智利同事的差旅费，以建立监测痕量金属（特别是Cd）的安排，作为沿海沃茨上升流变化的指标。当地学生将每月从沿海沿着选定的地点收集水样，并将其邮寄到PI的实验室进行分析。镉已被证明反映了营养物质的可用性，并被纳入底栖有孔虫的外壳。水样将提供一个基线，以确定每个地点与上升流有关的生产的季节性和年际周期;底栖有孔虫的年代沉积物样品将提供过去几千年上升流变化的记录。

9633173 vanGreen This award will support travel costs for the PI to visit colleagues in Mexico and Chile to set up arrangements for monitoring of trace metals (in particular Cd) as indicators of upwelling variations in coastal waters. Local students will collect monthly samples of water from selected sites along the coast and mail them to the PI's lab for analysis. Cd has been shown to reflect the availability of nutrients, and is incorporated in the shells of benthic foraminifera. The water samples will provide a baseline to determine the seasonal and interannual cycle of upwelling-related production at each site; dated sediment sample of the benthic foraminifera will then provide a record of upwelling variability over the past few thousand years.
