U.S.-U.K. Cooperative Research: Seasonal Gyres in the Coastal Ocean

9413299加文：这个为期两年的奖项支持由特拉华大学的理查德·W·加文和威尔士大学海洋科学学院的A·E·希尔领导的两个研究小组在沿海海洋学方面的美英合作研究。这项研究的目的是利用自由漂流浮标直接观测每年春夏形成的陆架海斜压涡旋(或螺旋)的流态。这些涡旋是在地形凹陷中由凹陷浅边缘和深中心之间不同数量的潮汐混合而产生的。虽然季节性斜压涡旋是一种新发现的现象，但似乎对沿海水域污染物的扩散、浮游幼虫的滞留和陆架海洋环流的性质具有重要的生态后果。研究人员将对苏格兰海岸外的季节性斜压涡旋进行联合实地观测，然后对观测数据进行一系列建模研究。英国将在RRS挑战者号科考船上提供航行时间。通过结合两个研究小组的模拟能力和观测资源，特别是在卫星跟踪的漂浮物中，研究人员将获得大陆架海洋环流的最佳覆盖范围和分辨率。

9413299 Garvine This two-year award supports U.S.-U.K. cooperative research in coastal oceanography between two research teams led by Richard W. Garvine, University of Delaware, and A.E. Hill at the School of Ocean Sciences, University of Wales. The objective of the research is to directly observe, using free-drifting buoys, the flow regime of baroclinic gyres (or spirals) in shelf seas which form in spring/summer each year. These gyres are produced in topographical depressions by differing amounts of tidal mixing between the shallow edges and deep center of the depressions. Though a newly discovered phenomenon, seasonal baroclinic gyres appear to have important ecological consequences for dispersal of contaminants in coastal waters, on retention of planktonic larvae, and on the nature of shelf sea circulation. The researchers will conduct joint field observations of seasonal baroclinic gyres off the coast of Scotland and then apply a series of modeling studies to the observational data. The United Kingdom will provide ship time on the research vessel RRS Challenger. By combining the modeling capabilities and observational resources of the two research groups, especially in satellite-tracked drifters, the researchers will obtain optimal coverage and resolution of shelf sea circulation.
