MAR DEL PLATA, Argentina — An Argentine submarine found deep on the ocean floor a year after it vanished with 44 people on board may rest there despite pleas from family members of the crew, who hope for a salvage operation that experts say would be costly and unlikely to yield new information.

Experts say the salvage operation appears to be feasible. But the financially struggling administration of President Mauricio Macri is not eager to pay for it despite pressure from families who want to recover the bodies of their loved ones.

For now, the only official in a position to order the vessel to be lifted quickly does not seem in a hurry to do so.

Marta Yáñez, the federal judge who is in charge of the investigation into the sinking of the submarine, the San Juan, is working with experts to review 67,000 photographs and videos of the submarine and its surroundings to determine what exactly happened to the vessel.
