    Re: Nansen question
    From: George Huxtable
    Date: 2009 Dec 11, 12:00 -0000

    A follow-up to my earlier posting, which attempted to answer Apache Runner's
    question about the origin of the Ekman theory of wind drift.
    
    I suggested that Nansen's publication "Some results of the Norwegian Arctic
    Expredition 1893-96" might be productive, but a look in Abebooks tells me
    that slim volume is just reprinted from an item in the Journal of the Royal
    Geographical Society, presumably for 1897. So that may be findable in an
    academic library.
    
    But I've also discovered that the results were gathered into a series of (at
    least) 6 volumes, "The Norwegian North Polar Expedition 1893-1896 Scientific
    Results Vol 1", etc, edited by Nansen (presumably in English). These were
    reprinted by Greenwood Press, New York, around 1970, so should be available
    in libraries. And I see that Ekman made at least one contribution to that
    series (on "Dead-water", in vol 3).
    
    I remember learning about the Ekman theory, in an oceanography course in the
    early 1950s (and being a bit sceptical).

    | Yes, it was on the Fram expedition of 1893-96, , when Nansen made the
    | observation sthat led to the Ekman spiral, according to "The Oceans",
    | Sverdup, Johnson, and Fleming (1942), page 492.
    |
    | I have the two volumes of Nansen's "Furthest North", but a very-quick scan
    | from the index has only led to passages which seem to imply that ice was
    | drifting straight downwind, not at an angle. But Nansen says that further
    | publications will follow with the scientific details. He later published
    | which might be
    | productive, but I don't know it.

    || Does anyone know the original publication of Nansen's work that led to
    the
    || Eckman theory of currents?
    ||
    || As I recall, he noticed that icebergs moved at some angle (30-40 degrees)
    || with respect to the direction that the wind was blowing them and deduced
    || that it was due to the combination of the wind and the Coriolis effect.
    || That observation was the basis of the Eckman theory.   I'm curious about
    | the
    || expedition this was sighted on.    I think it was the famous Polar drift
    | of
    || the Fram, but I'm not sure.   I don't recall seeing it written in
    Furthest
    || North (quite a tale, too), so I'm assuming it was a scientific
    | publication.
    ||
    || Anyone know?
