    Dear George,
    I am using few hours before my departure
    to reply your interesting messages this morning.

    Now I understand what you are saying about conditions
    giving anomalous (reversed) dip.
    (I would still like to better understand the physics of this
    phenomenon). Next time I observe from a beach in Kielerforde,
    I will record the temperature of air and water.

    It seems very interesting to me, if true, that such things can
    distort the dip by 3'.5

    Alex
