EAGER: Evaluating the efficacy of the DSV-2 Alvin in scientific operations via a scientific verification cruise (SVC)

HOV Alvin进行了大修和升级，自2010年12月起停止使用。升级包括：一个更大的人员范围，增加了两个视窗，能够潜入6500米深的水深；改进了照明和成像能力；改进了指挥和控制系统；以及增加了科学有效载荷能力。这辆车正在接受海军、海军海洋系统司令部(NAVSEA)的认证。在通过认证后，科学界将很重要地了解车辆在科学支持能力方面的变化意味着什么，特别是底部时间、与外部传感器和设备的集成、地面速度、机械手的灵活性、视频质量等。该奖项为科学验证邮轮提供资金。阿尔文用户的一个经验团队将在10-12潜水计划中验证车辆目前的能力，之后将向未来的阿尔文用户提供一份报告。计划中的潜水评估包括：*对深海和海底进行直接观测，最深可达4500米；*高清静止和视频成像/观测记录；*对海底和上覆水柱进行系统测绘/勘测(使用适当的传感器)；*在海底和上覆水柱收集材料和生物量(使用适当的取样器)；*在海底放置/回收仪器和着陆器；*在工作地点之间提供科学上有用的过渡时间；*对区域/生境/生物体进行系统勘探。潜水目标包括：圣地亚哥海槽；德尔玛甲烷渗漏；OMZ海底；拉霍拉峡谷；圣莫尼卡化石海；圣莫尼卡丘陵北部；以及推定的热液喷发(帕洛斯韦尔德斯)。邮轮期间计划进行人员转移，以容纳尽可能多的不同参与者。

HOV Alvin has undergone a major overhaul and upgrade, and has been out of service since December, 2010. The upgrades include: a larger personnel sphere with two additional viewports, which will be capable of diving to 6500m water depth; improved lighting and imaging capability; improved command and control systems; and, an increased science payload capacity. The vehicle is undergoing reinstatement of certification by the Navy, Naval Sea Systems Command (NAVSEA). Following certification, it will be important for the science community to understand what the changes to the vehicle mean in terms of science support capability, especially bottom time, integration with external sensors and equipment, speed over ground, agility of manipulators, video quality, etc.This award provides funding for a Science Verification Cruise. A team of experience Alvin users will validate the present capabilities of the vehicle in a 10-12 dive program, after which a report will be made available to future Alvin users. Planned dive assessments include:* Direct observations of the deep ocean and seafloor to depths of up to 4500 m;* HD still and video imaging/documentation of observations;* Systematic mapping/surveys of seabed and overlying water column (with appropriate sensors);* Collection of materials and biomass at the seafloor and in the overlying water column (with appropriate samplers);* Placement/recovery of instruments and landers at the seafloor;* Efficient Transit time that is scientifically useful between work sites;* Systematic exploration of regions/habitats/organisms.Targets dives include: San Diego Trough; Del Mar Methane Seep; OMZ bottom; La Jolla Canyon; Santa Monica Fossil seep; Santa Monica Mounds North; and, Putative hydrothermal venting (Palos Verdes). Personnel transfers are planned during the cruise in order to accommodate as many diverse participants as possible.
