Me thunk the Manhattan was built as a bog standard oil tanker - but did have an icebreaker
bow fitted for the voyage.
Dedicated icebreakers in addition to the strengthened bow also have a specialist hull design which the Manhattan did not (to move the broken ice away from vulnerable propellers / rudders etc. )and lots of welly in the engines
There are modern "double acting tankers" available since the 1990's which use a stern first approach to ice breaking (yes really!) and forward pointing for open water

Thanks, you're right.

Manhattan* 's route began in August 1969 on the east coast of North America and transited the passage from east to west via the Baffin Sea and Viscount Melville Sound. The master of Manhattan was Captain Roger A. Steward. Heavy sea ice blocked the way through M'Clure Strait, so a more southerly route through Prince of Wales Strait and south of Banks Island was used. A single, token barrel of crude oil was loaded at Prudhoe Bay and then the ship went back. She was escorted by the Canadian Coast Guard icebreaker CCGS John A. Macdonald. At various times during the expedition, Manhattan was supported by the icebreakers CCGS Louis S. St-Laurent, USCGC Staten Island, and USCGC Northwind.

Page is still a , tho'

But, for some reason he omits to mention that, while the passage is today described as 'fully navigable' in 1969 it was only traversible using the Manhattan - the biggest icebreaker in the world, an

Fourth lowest minimum in the satellite era, as I predicted, hailed a 'recovery' in some quarters ...

Some more context on the fourth-lowest-on-record ice figure might also be provided by recent research showing that the arctic ice cap has staged a remarkable recovery in recent years.

writes Lewis Page at El Reg. He also points out that

There still weren't any ice-scanner satellites during the summer minimum of 1969, when the 100,000-ton supertanker Manhattan - at the time the largest merchant vessel on the US registry - transited the Northwest Passage. The M'Clure strait was blocked then, too, just as it is this year, but the Manhattan got through via a route south of Banks Island. It sounds as though ice conditions that summer may not have been too dissimilar to this year.

But, for some reason he omits to mention that, while the passage is today described as 'fully navigable' in 1969 it was only traversible using the Manhattan - the biggest icebreaker in the world, and she was accompanied by 4 other super-ice-breakers, which one might have thought was relevant, in an article on sea-ice. Gotta love the Reg!

How would you explain that with the lack of pirates in the Artic ?

They have galleons not ice-breakers. HTH

More science pseudo bollux

Fake bollux? Is that truth?

[BrilloPad]

It has (probably) hit bottom, 1.8 million km2 below the average minimum.

More science pseudo bollux. No-one has any idea what is going on.

The only things one can be sure of are death, the sun rising and so called scientists(the new priests) spouting nonsense to get attention.

This post applies to AGW acceptors and deniers.

Arctic sea ice approaching normal

I'm pre-empting your "report" that the sea ice in the Arctic has increased by 12km^2.

Do you seriously believe that this is the only glacier to calve, or that sublimation is not a massive factor ?

Greenland's Jakobshavn Glacier sheds big ice chunk - BBC News


...of course, this is fictitious because in 1983 there was one hot day in Northern Ireland, which proves all the scientists wrong.
Also the calving has increased the amount of ocean ice for a while (what was once considered land ice is now sea ice), which I'm sure will be reported by some as further proof that the scientists are wrong.

Dropping like the Shanghai Composite.
