- Alvin is the world’s longest-operating deep sea submersible. It was launched in 1964 and has made more than 4,700 dives, along the way participating in some of the most iconic discoveries in the deep ocean. Throughout 2011, 2012 and into 2013, Alvin received a comprehensive overhaul and upgrade funded by the National Science Foundation that greatly expanded its capabilities and will eventually put almost the entire ocean floor within its reach.
The upgrade is taking place in two stages. After Stage 1 was completed in 2013, Alvin boasted several new improvements, including:
• A new, larger personnel sphere with an ergonomic interior designed to improve comfort on long dives
• Five viewports (instead of three) to improve visibility and provide overlapping fields of view for the pilot and two observers
• New lighting and high-definition imaging systems
• New syntactic foam providing buoyancy
• Improved command and control system
Several of these and other improvements to the sub have been designed to withstand descents to 6,500 meters-the remainder will be upgraded later. As a result, Alvin will initially maintain its current depth rating of 4,500 meters. In Stage 2, the entire sub will be upgraded to 6,500 meters depth. In addition, new batteries will be introduced to enable the submersible to stay at depth longer, giving scientists more time to work in unexplored parts of the ocean and putting 98 percent of the seafloor within their reach.

Seems like quite the upgrade! Welcome home, Alvin.
Dream job
This lovely white submarine has been upgraded ( grown up ) every year. Now this lovely submarine became more fat and chubby than ever before...
