I’m following the polar sailing expedition by Norwegian Børge Ousland and crew. As they head for a first possible encounter with ice in the Northeast passage through the Yugorsky Strait (the Kara Strait is currently closed by ice) they are well prepared.

Not all boats are as well prepared it seems. CBS News has reported the concerns of the Canadian Coastguard that the Arctic and the Northwest Passage in particular is becoming an attractive adventure for boats that are often ill-equipped and inadequately prepared for the dangers. Rescue by a coast guard ship is very expensive.
“Last summer, the crew of a 12-metre sailboat radioed that they were in danger of being crushed by ice. They wanted the icebreaker right away. The closest icebreaker was two days of sailing from them,” he said. “Finally the ice broke up and they could escape.” Full story here:
A summary of boats attempting the NW Passage in 2009 can be found on Explorers Web –this included the 40-foot Silent Sound, whose trip OpenExpedition.com was part-sponsored by the WWF.
It’s not just whether the ice melt is sufficient to allow passage of boats, ice moves in response to weather. One of last year’s successful passages describes it well:
“That evening’s ice chart was amazing: there was a clear lead on the east side of Peel Sound, which ran all the way down to and past King William Island. The next morning we headed off. [...] What the charts showed to be ice-free was now before us slowly turning into two-tenths coverage. It very quickly worked its way up to nine-tenths. As quickly as it filled in front of us, it came in behind us, blocking any retreat to the north. [...] The next morning we walked out onto the ice and took stock of our predicament [...] Where we were once a mile and a half off the beach, we were now only half a mile off and the pressure of ice building up to our west was slowly pushing us towards the rocks.”
They pushed their way out despite risking damage – five hours to get three miles off before they once again became firmly stuck. The next morning the GPS showed they had drifted seven miles with the ice overnight and several hours later they were back in clear water. They were fortunate (full story here).
Attempts this year include one using a RIB (rigid inflatable boat) and powered by bioethanol, two men in 17.5 foot open boats, and (my favourite) a solo voyage by Captain Tommy D Cook, in the “Cap’n Lem“. He is an experienced sailor and Master mariner and, unintentionally, quite a philosopher; his blog is a delight.

Meanwhile, according to a report in the Daily Telegraph, helped by ice-free water, archaeologists using sonar images have located the British ship that was sent to search for two lost vessels that were part of Sir John Franklin’s ill-fated 1845 Royal Navy expedition to discover the Northwest Passage (the website of former Canadian IceBreaker Polar Prince carries a good summary of the Franklin Expedition and the modern-day search for remains of the ill-fated ship). HMS Investigator was deployed in 1850 with a 66-man crew, but was eventually abandoned after being locked in the grip of Arctic ice for two winters.
“The first successful trip through the passage was recorded more than 50 years later by the Norwegian sailing and fishing boat Gjoa, captained by Roald Amundsen. It took the 21-metre vessel three years to travel east to west through the passage, wintering twice at Gjoa Haven and at King Point. The next craft to make the trip was the Royal Canadian Mounted Police wooden auxiliary schooner St-Roch, which made the first west-to-east transit of the passage from 1940 to 1942, wintering at Walker Bay and Pasley Bay. The same boat made the third successful trip through the passage and the first done in one season, in 1944. There were only five transits of the passage in the 1950s, 10 in the 1960s — nine of them in 1969 — but there were almost 70 in the 1990s. The most crossings in a single year were recorded in 2009, when 23 boats, two of them yachts, made the passage. That record is expected to be broken this year.” (CBS)
The Northwest Passage is not yet open this year. This year’s seasonal outlook for North American Arctic Waters (from Environment Canada here) reports low levels of old ice in key areas of the passage but predicts:
“…the lack of old ice in the northern portions of M’Clure Strait and Viscount Melville Sound coupled with the thinner than normal first-year ice measured in the Western Arctic will allow for the thicker multi-year ice to leave the Archipelago area and move southward into the Northwest Passage.”
Now if you’d asked me I’d have suggested 2007 as a year of minimum ice in the NW Passage, but apparently it was 1998 (graph below). Interesting that the maximum coverage is less than 30%, and that there is no real pattern to the last 30 years.
