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
