Recovery of the UMCES MUDBED Surface Buoy

该浮标于2009年作为nsf资助的多学科底栖生物交换动力学（MUDBED）项目的一部分部署，作为水下粒子沉降相机系统和基于实时单元的数据传输到ftp服务器之间的表面连接。水下传感器组件于2009年8月被打捞上来。2010年4月底曾试图回收海面浮标，但由于计划回收系统的重要元件被切断，以及在恶劣的风潮条件下站位困难，未能成功。海面浮标必须在2010年回收。从科学设备的角度来看，浮标及其附带的太阳能电池板和光电数据/电力电缆是未来海洋野外项目的宝贵资源。这项提议中最重要的方面是避免对航行的潜在危险。链条和/或连接环不可避免地会因腐蚀或磨损而失效，并使浮标脱落，此时它将大幅度摆动（如果只有一条链条断裂）或随潮汐自由漂浮。

The PIs have requested a RAPID award to recover a surface buoy 2-point anchored in the middle reaches of the York River, VA. The buoy was deployed in 2009 as part of the NSF-funded Multi- Disciplinary Benthic Exchange Dynamics (MUDBED) project, as the surface link between an underwater particle settling camera system and real-time cell-based data transmittal to an ftp server.The underwater sensor package was recovered in August 2009. An attempt was made to recover the surface buoy at the end of April 2010, which failed because important elements of the planned recovery system had been cut and because of station-keeping difficulties under difficult wind and tide conditions. The surface buoy must be recovered during 2010.. From a scientific equipment perspective, the buoy with its attached solar panels and electro-optical data/power cable are valuable resources for future oceanographic field programs. The most important aspect of this proposed effort is avoiding potential hazards to navigation. The chain and/or connecting shackles will inevitably fail through corrosion or wear and allow the buoy to become detached, at which time it will swing widely (if only one chain breaks) or float free with the tide.
