Gliders in the Gulf Stream

The overarching goal of this project is to collect high resolution transects across the Gulf Stream. Though the speed of the Gulf Stream greatly exceeds the speed of a glider, gliders can be flown across the current as they are advected downstream. Missions prior to 2015 were conducted downstream (northeast) of Cape Hatteras, primarily between Cape Cod and Bermuda; missions since 2015 begin in Miami, FL and are planned to end on the New England continental shelf. During a typical 100-day mission between Miami and Cape Cod, a single glider completes 6-10 crossings of the Gulf Stream, returning approximately 800 profiles to the shallower of the sea floor or 1000 m. The current operational goal is to maintain at least one glider in the Gulf Stream at all times. Additional plots of these data are available at http://gliders.whoi.edu.

本项目的总体目标为收集跨越墨西哥湾流的超高分辨率横断面数据。尽管墨西哥湾流的流速远超水下滑翔机的速度，但水下滑翔机仍能随水流下游前进。2015年之前的任务主要在哈特拉斯角东北方向进行，主要位于科德角和百慕大之间；自2015年起，任务始于佛罗里达州的迈阿密，计划在东北大陆架结束。在典型的100天任务中，从迈阿密到科德角，单一水下滑翔机完成6-10次墨西哥湾流的穿越，返回大约800个海床较浅或1000米深处的剖面。当前的操作目标是始终保持至少一架水下滑翔机在墨西哥湾流中。这些数据的附加图可以在http://gliders.whoi.edu获取。
