Mystery In The Sea Of Okhotsk

Whatever happened in the sea of Okhotsk, the area most conspicuously “free” now from polar ice when compared to 30 years ago?

Of the 400,000-odd sq km missing from the average, 300,000 concern the sea of Okhotsk, and 100,000 the sea of Barents.

In any case, anomalies are overrated as a tool to understand what happens at the Poles. For example the Arctic Basin anomaly is zero, simply because there is only so much ice cover possible for it. If the average is 100%, even the coldest year will never show a positive anomaly…

  1. There is a report on the web that assesses the oil pollution levels in the Sea of Okhotsk and finds them negligible. This is a shame as otherwise it would provide a neat bit of evidence supporting the Kriegesmarine theory of GW. Oil pollution smooths the sea surface. Fewer waves break, less spray, fewer CCNs, less cloud, more insolation. Smoother surfaces mean lower albedo but also lower emissivity, so in northerly latitudes more heat is retained at night. One wonders who wrote the report.

    For anyone with an unemployed grad student it might be worth while setting them to checking the relationship between offshore oil drilling and ice loss in Barents, Okhotsk and Chukchi/Beaufort.

  2. The map and accompanying graphs from Cryosphere Today to which you refer being particularly unhelpful, I just googled “Arctic ice coverage” in an unsuccessful attempt to find a useful satellite image I’d recently been looking at which showed open water within the Arctic circle, but solid ice way down the American seaboard, and which led me to wonder whether the lovely spaghetti graphs produced by the Danes, Norwegians and Coloradans referred only to the area within the Arctic circle, or to the whole Northern Hemisphere. Since albedo is being quoted everywhere as a possible source of positive feedback, it seemed important to know. Any anwers?
    The search brought me back to Cryosphere Today and their homepage. They have a number of images to click on, with enticing labels, such as:

    1) The 40Mb animation at the left shows the recent dramatic loss of multiyear sea ice

    2) View the updated high resolution animation of this year’s [sic] sea ice retreat (01/01/2007 – 09/23/2007).[…] it illustrates nicely the temporal evolution of this year’s [re-sic] sea ice [i.e. from winter to summer]

    3) Peruse an archive of map displays of the atmospheric and radiative climatic conditions leading up to the record setting Northern Hemisphere sea ice minimum of 2007 [i.e. not including the almost back to normal 2008 minimum]

    I’m sure the scientific data on offer is above reproach, but as to the accompanying blurb, I’ve seen better from my Nigerian financial advisers
