Observing ocean-atmosphere interaction from the poles to the tropics with an AutoNaut autonomous surface vehicle

该项目将使用令人兴奋的新型波浪推进自动水面车辆AutoNaut(将被命名为Caravela)，该车辆于2017年订购，最近交付。它的购买资金来自欧洲研究理事会授予主要监管人凯伦·海伍德的高级赠款指南针。它将是一种独特的运载工具，专门设计用于携带和部署海豹滑翔机。博士生的学习是及时的，因为通过从一开始就参与，学生将有机会与项目调查人员、研究人员和技术人员一起学习车辆和传感器的操作和使用。这将给学生一种独立和新奇的感觉，以及团队合作能力。显然，开发一项新技术存在一些风险，但该项目是用后备计划设计的。UEA与总部位于奇切斯特的中小企业AutoNaut Ltd发展了良好的工作关系。我们正在共同设计和测试用于将Seaglider携带和部署到AutoNaut通过COMPASS项目为我们建造的远程环境的新型机制。此外，我们是目前由AutoNaut有限公司牵头的一个创新英国项目的联合调查员，该项目在罗兰·冯·格拉索海冰室测试AutoNaut的防冰涂层和坚固性。该项目将建立在这两项计划的基础上，并加强我们的合作，为学生提供参与海洋业务的独特机会，并了解如何应对工程挑战。Caravela将于2019年底在英国水域进行试验，我们预计学生将参与这些试验，学习车辆的操作、部署和驾驶，以及对传感器和数据质量的评估。我们的第一次科学试验是在2020年1月至2月，利用副主管本·韦伯的邀请，参加一个重大的欧洲项目Eurec4a。Eurec4a是一项海空互动活动，包括飞机、船只和陆基活动。作为对该项目的一项贡献，我们将从巴巴多斯发射Caravela，她将前往研究区域，在那里她将部署剖面海滑器。实地行动结束后，海滑艇将被其中一艘船找回，卡拉维拉将利用自己的波浪动力返回巴巴多斯。部署Seaglider和Caravela将使我们能够量化大气通量对上层海洋边界层发展的影响。学生的第二个实地活动将是2021年初在南极部署AutoNaut，要么是结合国家科学研究中心资助的Tarsan项目(国际Thwaites冰川合作的一部分)在阿蒙森海，要么是结合国家科学研究中心资助的短笛项目(国家科学研究中心计划玫瑰的一部分)在韦德尔海。首席主管凯伦·海伍德是这两个项目的PI。这些项目包括部署自动车辆来研究海洋、大气和海冰之间的相互作用。该学生将加入COAS，这是一个卓越的大气和海洋科学中心。他们将成为UEA滑翔机科学小组的一部分，该小组以合作的形式运作，所有学生都参与滑翔机的部署、试验和驾驶，作为他们训练的一部分。

This project will use the exciting new wave-propelled autonomous surface vehicle AutoNaut (to be named Caravela), ordered in 2017 and recently delivered. Its purchase was funded through the European Research Council Advanced Grant COMPASS awarded to primary supervisor Karen Heywood. It is to be a unique vehicle, specially designed to carry, and deploy, a Seaglider. The PhD studentship is timely because, by being involved from the beginning, the student will have the opportunity to learn the operation and use of the vehicle and sensors alongside the project investigators, researchers and technicians. This will give the student a sense of independence and novelty, together with teamwork skills. Obviously there are some risks with the development of a new technique, but the project has been designed with backup plans.UEA has developed a good working relationship with AutoNaut Ltd, an SME based in Chichester. Together we are designing and testing the novel mechanisms for carrying and deploying the Seaglider into remote environments that AutoNaut are building for us through the COMPASS project. In addition, we are Co-Investigators of a current Innovate UK funded project, led by AutoNaut Ltd, trialling anti-icing coatings and testing robustness for AutoNaut in the Roland von Glasow Sea Ice Chamber. This studentship will build upon both initiatives and strengthen our collaborations, offering a unique opportunity to the student to be involved with a marine business and see how engineering challenges are addressed.Caravela will be trialled in late 2019 in UK waters and we anticipate that the student will participate in these trials, learning about operation, deployment and piloting of the vehicle, together with assessment of the sensors and data quality. Our first science trial is January-February 2020, taking advantage of an invitation to co-supervisor Ben Webber to participate in a major European project Eurec4a. Eurec4a is an air-sea interaction campaign, with aircraft, ships and land-based activities. As a contribution to the project, we will launch Caravela from Barbados, and she will travel to the study region, where she will deploy the profiling Seaglider. After the field campaign, the Seaglider will be recovered by one of the ships and Caravela will return to Barbados under her own wave-power. Deploying a Seaglider in conjunction with Caravela will enable us to quantify the impact of atmospheric fluxes on the development of the upper ocean boundary layer.The student's second field campaign will be a deployment of AutoNaut in early 2021 in the Antarctic, either in the Amundsen Sea in conjunction with the NERC-funded TARSAN project (part of the International Thwaites Glacier Collaboration) or in the Weddell Sea in conjunction with the NERC-funded PICCOLO project (part of the NERC programme RoSES). Primary supervisor Karen Heywood is the PI of both projects. These projects involve deployments of autonomous vehicles to investigate the interactions between ocean, atmosphere and sea ice.The student will join COAS, a centre of excellence in atmospheric and oceanographic science. They will be part of the UEA Glider Science group, that operates as a cooperative with all students being involved in glider deployments, trials and piloting as part of their training.
