Floating Our Boat

In a sign that the current maintenance period for the research vessel Atlantis is almost completed, yard workers at the Mares Island Naval Ship Yard recently flooded the drydock where they were working on the ship. Work will continue at a nearby pier until mid-March, when Atlantis and the human-occupied submersible Alvin will continue their regular schedule of research operations.
