Image Of the Day repeat caption:
The human-occupied submersible Alvin surfaces from a mission to the seafloor in a photo taken circa 1967 three years after the sub was first built. Two crewmen known as swimmers assist in the sub's recovery, as other crew members watch from Lulu, Alvin's first tender ship. Since those early years, Alvin has been upgraded many times, taking on different appearances as new components and engineering designs are added. Alvin got a major upgrade in 2014, adding a new titanium personnel sphere. Additional upcoming improvements will complete the requirements for Alvin to increase its diving capacity from 4,500 to 6,500 metersdeep enough to provide access to 98 percent of the seafloor.

A photo, circa 1967, shows the research submersible Alvin with two support swimmers, as crew watch from Lulu, Alvin's first tender ship. WHOI still operates the U.S. Navy-owned Deep Submergence Vehicle (DSV) Alvin for the oceanographic research community. Built in 1964, the little white sub has more than 4,200 dives (as deep as 4,500 meters) and many "firsts" to its credit, including exploring hydrothermal vents, surveying the sunken RMS Titanic, and collecting new deep-sea species. Now, Alvin enters the next phase: the sub will have a new titanium personnel sphere and enhanced research capabilities.
