Robot heading for Antarctic dive

The mysteries of the Antarctic deep will be probed by a new vessel capable of plunging 6.5km (four miles) down.

Isis, the UK’s first deep-diving remotely operated vehicle (ROV), will be combing the sea-bed in the region in its inaugural science mission.

Researchers hope to uncover more about the effects of glaciers on the ocean floor, and also find out about the animals that inhabit these waters. …

Professor Paul Tyler, a deep-sea biologist at NOC, will use Isis to survey the sea creatures of Marguerite Bay.

“I’m interested in the effects of glaciers on the sea-bed and how this affects the fauna – the animals. I’m also interested in how the animal life in Antarctica changes as one goes deeper and deeper into the water,” Professor Tyler said.

“Using the real-time imagery from the ROV, we will be able to look at what is happening as it happens, helping us to answer questions such as why some creatures exist at one depth and not another.

“We are hoping to see a whole bunch of large creatures such as star fish, sea cucumbers, sea fans, sea pens, etc, that inhabit the deep shelf slope and abyssal depths.”

He added: “Essentially no-one has explored Antarctica using a ROV at these depths.”

  1. Deep sea ‘Alvin’ designer Froehlich dies

    By GREGG AAMOT, Associated Press Writer Wed May 23, 8:17 PM ET

    MINNEAPOLIS – Harold E. Froehlich, who designed a deep-sea vessel used to explore the wreckage of the Titanic and search for ocean life forms, has died, his family said Wednesday. He was 84.

    He had cancer and died May 19 at a suburban hospital, his family said.

    Froehlich was named project manager for the vessel, named Alvin, in 1962 when the Navy and the Woods Hole Oceanographic Institute gave General Mills a contract to build a small, deep-diving submarine. Two years earlier, he had helped build a mechanical arm for the Navy-owned bathyscaph Trieste, which once descended more than 35,000 feet.

    Alvin — nicknamed after Allyn Vine of the Oceanographic Institute — could reach depths of more than 14,000 feet. In 1966, it was used to find a hydrogen bomb that was lost after a U.S. military plane crashed off the Spanish coast. Later, scientist Robert D. Ballard found giant tube worms and other then-undiscovered life 7,000 feet underwater off the Galapagos Islands.

    In 1986, Ballard used Alvin to explore and photograph the Titanic, which rested more than 12,000 feet underwater in the North Atlantic.

    Alvin has made more than 4,100 dives, according to the Woods Hole Oceanographic Institute.

    Though Alvin was his best-known project, Froehlich worked on many others during his career, such as high-altitude balloons and, after joining 3M Co., surgical equipment such as skin staplers, his wife, Avanelle Froehlich, recalled Wednesday.

    Asked what he was most interested in, she said: “I think anything that he could puzzle out and make work. And, of course, his family.”

    Harold Edward Froehlich was born July 13, 1922, in Minneapolis and was a Navy signalman during World War II.

    He retired from 3M in 1989.
