Is the Alvin submersible still being used?

The U.S. Navy's ALVIN (DSV-2) is still on loan to the Woods Hole Oceanographic institute, and was refitted in 2011. She began shallow diving operations in 2012, and is expected to be back at full depth capability by 2015.

ALVIN is no spring chicken though, and a possible replacement has been in the works for some time. However, given budget constraints, that'll likely get put on the back burner.
