The structure of the cross-shelf flow has been of interest to coastal oceanographers for decades because it determines the depth at which upwelled water originates. This project will test a new idea that differences in stratification determine whether the upwelled water comes from bottom boundary layers (under weak stratification) or from interior depths (under strong stratification). Analysis of existing datasets and numerical models will be used to test and further develop this idea. This project has important implications to other coastal oceanographers interested in the transport of nutrients, larvae or geochemical materials.

几十年来，跨大陆架流的结构一直是沿海海洋学家感兴趣的问题，因为它决定了涌升水起源的深度。该项目将测试一个新的想法，即分层的差异决定了涌上水是来自底部边界层（弱分层下）还是来自内部深处（强分层下）。对现有数据集和数值模型的分析将用于测试和进一步发展这一想法。该项目对其他对营养物、幼体或地球化学物质的运输感兴趣的沿海海洋学家具有重要意义。
