This RAPID project is to deploy instrumentation to study the behavior of the Gulf Stream at the region where it detaches from the continental margin. Instrument deployments will be leveraged by ongoing activities in the area, as part of the Ocean Observatories Initiative's Pioneer array, near the shelf break north of Cape Hatteras. Likewise, these deployments will provide complementary information to that obtained from the Pioneer array. The RAPID project will involve students at different stages in college and graduate school.This one-year RAPID grant is to deploy two inverted echo sounders (CPIEs, with current meters and pressure sensors) over the continental slope north of Cape Hatteras, where the Gulf Stream separates from the continental margin. Instruments will be installed at depths of 1000 m during a period of 4 years. Deployments will take place in June 2024 with ships of opportunity and adjacent to the new location of the Coastal Pioneer Array. Data will be sent to shore via satellite link and shared via a Zenodo repository. Information from these deployments will complement continental shelf data from the Pioneer array, and will be used to study multi-scale (in time) processes associated with Gulf Stream separation from the continental margin. As Broader Impacts, the CPIEs measurements will help in quantification of exchange processes between the shelf and the open ocean. The project will include two undergraduate and two graduate students.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteriaThis award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

这个快速项目是部署仪器，以研究墨西哥湾流在其从大陆边缘分离的区域的行为。该地区正在进行的活动将利用仪器部署，作为海洋观测站倡议先锋阵列的一部分，靠近哈特拉斯角以北的大陆架断裂。同样，这些部署将为从先锋阵列获得的信息提供补充信息。RAPID项目将涉及大学和研究生院不同阶段的学生，这项为期一年的RAPID赠款将在哈特拉斯角以北的大陆坡部署两个反向回声测深仪（带有流速计和压力传感器），墨西哥湾流在那里与大陆边分离。 仪器将在4年内安装在1000米的深度。部署将于2024年6月进行，并将与机会舰一起在沿海先锋阵列的新位置附近进行。数据将通过卫星链路发送到海岸，并通过Zenodo储存库共享。这些部署的信息将补充先锋阵列的大陆架数据，并将用于研究与湾流从大陆边分离有关的多尺度（时间）过程。作为更广泛的影响，CPIEs测量将有助于量化大陆架和公海之间的交换过程。该项目将包括两名本科生和两名研究生。该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。该奖项反映了NSF的法定使命，并已被认为是值得通过使用基金会的智力价值和更广泛的影响审查标准进行评估的支持。
