Cruise ship stranded in Antarctic with 122 on board
Admiral Daniel Martin told local television a nearby passenger ship was on its way to the stricken Panamanian-flagged vessel, called the Ushuaia after the Tierra del Fuego port from which it sailed in Argentina on Sunday.
He said none of the boat's passengers had been injured.
"We've received information from the captain of the Ushuaia that the boat is grounded ... with a minimal amount of water coming in and some fuel loss," Martin said.
He said the ship lay some 186 miles (300 km) southwest of Argentina's Marambio military base on the Antarctic Peninsula.
Cruise travel has grown in Antarctica in recent years, with tourists paying thousands of dollars to see towering icebergs, seals, whales and penguins.
A year ago, more than 150 crew and passengers, many of them elderly, escaped unhurt in a dramatic rescue after their cruise ship hit ice off Antarctica and sank.
The ship is operated by Antarpply Expeditions, based in Ushuaia.
