The PIs have requested a Small Grant for Exploratory Research (SGER) to mount a recovery cruise for the mooring and sensor systems of the Real Time Offshore Seismic Station (RTOSS) that was deployed on the Kick?em Jenny volcano just north of Grenada in May of 2007. This system suspiciously ceased operation 8 days after a successful deployment, and subsequently was parted from its surface buoy. The RTOSS system ceased operation as a result of an apparent coincident failure of the radio modem, the control link and ARGOS telemetry. Among the possible causes of this failure are flooding of the buoy well and collision with a vessel causing damage to antennas that were attached to the centrally located mast. Without recovering the subsurface portion the PI?s can only speculate about what may have happenedBroader ImpactsThe mooring design seeks to address a difficult problem with moorings requiring real time telemetry from bottom founded equipment and had undergone a successful preparatory test deployment

PIS申请了探索性研究小额赠款(SGER)，为2007年5月部署在格林纳达北部Kick？em Jenny火山的实时近海地震台(RTOSS)的系泊和传感器系统进行回收巡航。该系统在成功部署8天后可疑地停止运行，随后与其水面浮标分离。由于无线电调制解调器、控制链路和Argos遥测明显同时发生故障，RTOSS系统停止运行。造成这一故障的可能原因包括浮标井被淹，以及与船只相撞，损坏了安装在中央位置的桅杆上的天线。如果不能找回海底部分，皮？S只能推测可能发生了什么。桥式冲击系泊设计旨在解决系泊设备需要从底部建立的设备进行实时遥测的难题，并已成功地进行了预备测试部署
