A Tracer Release Experiment in the Brazil Basin

Ledwell OCE-9906685 1996年在巴西盆地一个山谷上方约1000米和周围深海丘陵顶部上方500米的密度面上有目的地释放的示踪剂斑将在2000年重新取样，以显著扩大对底辟扩散率和水平扩散的直接测量。此外，还将部署几个剪切计浮子，以在空间上扩展1998年在释放示踪剂的山谷上方部署的单个海流计系泊所收集的内波剪切场的观测。

Ledwell OCE-9906685The tracer patch that was purposefully released in 1996 in the Brazil basin on a density surface about 1000 meters above one of the valleys, and 500 meters over the tops of the surrounding abyssal hills will be resampled In the year 2000nto significantly extend the direct measurements of diapycnal diffusivities and horizontal dispersion. In addition, several shearmeter floats will be deployed to spatially extend the observations of the internal wave shear field gathered with a single current meter mooring deployed in 1998 above the valley were the tracer was released.
