Autonomous Underwater Vehicle Measurements of Arctic Change due to Atlantic Inflow

该项目将开发一种用于北极浮冰下的自主水下航行器（AUV）。AUV将配备海洋仪器，用于沿着选定的水深等高线收集数据。该仪器将通过融化冰层的吊舱发送数据包，并通过卫星将数据遥测到基站。大部分开发费用由国家海洋学伙伴计划承担。该项目是对用这笔资金开发的整套仪器进行概念验证测试。该测量系统的科学应用是收集数据，研究大西洋暖层侵入北极造成北极环流的根本变化，并可能与更大的北极变暖有关。AUV将提供一种在浮冰下远程和快速收集数据的方法，而其他系统需要人工干预，在非常危险的环境中需要更大的后勤成本和风险。

This project will develop an Autonomous Underwater Vehicle (AUV) for use under the Arctic pack ice. The AUV will be equipped with oceanographic instruments that will be used to collect data along a chosen bathymetric contour. The instrument will send up data packages in a pod that melts through the ice and telemeters the data through a satellite to a base station. Most of the development costs have been borne by National Oceanographic Partnerships Program. This project serves as a proof-of-concept testing of the instrument package developed with that funding. The scientific application of the measurement system is to collect data to study the warm Atlantic layer incursion into the Arctic that has caused a fundamental change in Arctic circulation and may be linked to a larger Arctic warming. The AUV will provide a means for collecting data remotely and quickly under the pack ice where other systems require human intervention at a much greater logistical cost and risk in a very hazardous environment.
