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.

Hov Alvin经历了重大改革和升级，自2010年12月以来一直停止使用。升级包括：一个较大的人事领域，具有两个额外的视口，可以潜入6500m的水深；提高照明和成像能力；改进的命令和控制系统；而且，科学有效载荷能力提高。 该车辆正在恢复海军海上系统司令部（NAVSEA）的认证。 经过认证后，对于科学界而言，了解车辆的变化在科学支持能力方面的意义将非常重要，尤其是底部时间，与外部传感器和设备的集成，地面速度，操纵器的敏捷性，视频质量等。该奖项为科学验证巡游提供了资金。 Alvin用户的一支经验团队将在10-12的潜水计划中验证车辆的当前功能，然后将向未来的Alvin用户提供报告。 计划的潜水评估包括：*直接观察深海和海底的深度，最高4500 m；* HD静止以及观察结果的视频成像/文档；*海底的系统映射/上上面的水柱（与适当的传感器）（适当的传感器）；海底；*工作地点之间科学有用的有效运输时间；*对区域/栖息地/生物体的系统探索。潜水包括：圣地亚哥槽； Del Mar甲烷渗水； OMZ底部；拉霍亚峡谷；圣莫尼卡化石渗水；圣莫尼卡北部丘陵；并且，假定的热液排气（palos verdes）。 计划在巡航过程中进行人员转移，以适应尽可能多的不同参与者。
