Terray An observational study of the vertical structure of currents and turbulence in the ocean mixed layer will conducted at two off the New England Coast. Special emphasis will be put on the near surface region that is strongly influenced by surface waves through breaking and Langmuir circulation. This project relates to the more general question of the coupling between the atmosphere and the ocean by providing a link between surface fluxes and the mixed layer interior in a region that is poorly characterized. The two fields experiments will be conducted during winter when the water column is approximately unstratified. One deployment will be on the New England Shelf under conditions of well-developed waves, whereas the second deployment will be in a large bay and will focus on strongly forced, fetch-limited waves.

将在新英格兰海岸外的两个地点对海洋混合层中海流和湍流的垂直结构进行观测研究。特别强调将放在近地表区域，强烈影响表面波通过打破和朗缪尔环流。该项目涉及大气与海洋之间耦合的更一般性问题，在一个特征不明确的区域提供表面通量与混合层内部之间的联系。这两个领域的实验将在冬季进行时，水柱近似不分层。 第一次部署将在波浪发育良好的条件下在新英格兰大陆架上进行，而第二次部署将在一个大海湾中进行，并将重点放在强强迫、取量有限的波浪上。
