US-GLOBEC: Satellite-Derived Estimates of Mixing Across Sea Surface Temperature Fronts in the Georges Bank Region

乔治浅滩是一个大型海底浅滩，位于马萨诸塞州科德角东南部，将缅因州湾与北大西洋西部隔开。 潮汐混合锋（TNF）形成沿着点的轨迹，其中热诱导浮力输入等于潮汐混合诱导浮力去除，分离垂直充分混合的沃茨分层的沃茨。 乔治海岸前缘和附近的陆架/陆坡前缘（SSF）的位置可以使用海表温度（SST）锋来确定，现在可以使用自动化方法从卫星获得的SST图像中绘制。 作为Georges Bank GLOBEC第三阶段项目的一部分，我们将利用覆盖Georges Bank、缅因州湾、西斯科舍大陆架和附近斜坡地区的每日无云AVHRR卫星图像，实时并在万维网上向研究船和合作者提供SST锋面位置。 我们将保持一个非常大的数据档案，其中包括近实时获取和处理的所有原始AVHRR SST图像，以及相应的SST锋面位置图像和数据，研究船和合作调查人员可通过高速拨号电话线和万维网查阅这些图像和数据。

Georges Bank is a large submarine bank located southeast of Cape Cod, Massachusetts, separating the Gulf of Maine from the western North Atlantic. A tidal mixing front (TNF) forms along the loci of points where the thermally-induced buoyancy input is equal to the tidal mixing-induced buoyancy removal, separating vertically well-mixed waters from stratified waters. Locations of the Georges Bank TMF and nearby shelf/slope front (SSF) can be determined using sea surface temperature (SST) fronts, which can now be mapped from satellite derived SST images using automated methods. As part of the Georges Bank GLOBEC Phase III project we will provide SST frontal positions to research vessels and collaborators, in real-time and on the World Wide Web, using daily cloud-cleared AVHRR satellite images which cover Georges Bank, the Gulf of Maine, the western Scotian shelf and nearby slope regions. We will maintain a very large data archive, containing all raw AVHRR SST images, acquired and processed in near real-time, together with corresponding SST frontal location images and data, which is accessible to research vessels and collaborating investigators over high-speed dial-in telephone lines and the World Wide Web.
