The Alvin is a research sub that has achieved explorations of famous shipwrecks such as the Japanese Shinkai and the Titanic. Being capable of handling 15,000 feet descent has made the Alvin research sub the deepest-diving sub of the world.
The 36,000 pounds Alvin research submarine functions in the same manner as other subs. This means that the research ship needs humongous support ships to house people, motors, and electronics.
The four-hour floor time of the Alvin research sub is probably its only downside. It’s because of the battery technology limitations. This, in turn, results in an incredible inefficiency for scientists to gather the seafloors data.
Yet, this is not the end of the story for the Alvin research sub. Plans are underway to upgrade maneuverability and sample-collecting systems of the research sub.
Renovating the Alvin research sub depends on available funds. Woods Hole, the navy institution responsible for the Alvin research sub is dependent on NASA’s budget to get things going.
To date, the Alvin research sub still needs another upgrade to enable a dive of up to 21,000 feet. 10-hour dives have become the norm for the research sub today. This is a vast improvement from the limited four-hour capability of the research sub in the past decade.
