The variability of ice distribution in the Nordic Seas is considered for the period 1966-1988. The average maximum extension is found to be nearly constant for the whole area, except for the Iceland Sea where there is a reduction of about 33%. The average minimum extension shows a reduction between 13% and 40%, except for the Greenland Sea where the changes are insignificant. The largest reductions in the minimum extension ...
Upper winds were measured by Rawin (SCR658) using a separate unmodulated 400 mc transmitter attached to the sounding balloon. The first ascent was made on 15 March 1950, and daily ascents commenced on 1 April 1950 and continued until 10 January 1952, when 626 upper wind measurements had been completed. A much better idea of the air circulation over the Antarctic has been gained from the investigations carried out during ...
