164 DISCUSSION ON INTERPRETATION OF ICE
thing new. Everyone thought that the amount
of open water between ice floes depended on
how much ice there was pushing the floes to-
gether. This is so. There is also the question of
the sub-marine contours.
Another correlation they have found is that
between tidal movements and small fractures
in ice, particularly ice which is fast to the shore.
Another is that between the shape of puddles —
which you have seen very well in Dr Teleki's
pictures — and the sub-ice profiles, that is to say
the countours of the underside of the ice.
All these are very interesting points which I
have not seen developed in any of our western
literature, and I should like to hear from the
Russians about it. We have only got one general
paper from which I have derived this informa-
tion. We have not the real observations on which
the writer of the general paper based his re-
marks. I should like to get them, I hope I shall.
One final point on the subject of ice obser-
vation from artificial satellites, I would like to
point out that there have been a little more
impetus given to this question at the recent
meetings at Cambridge of the Special Committee
of Arctic Research who have passed a resolution
urging authorities using weather satellites to try
to get high altitude pictures of ice distribution
out of them. This is a helpful thing which could
lead to interesting information from them.
Capt RAGNAR THoRÉN: Time is up, and I
should like to say that discussion will go on on
Professor Telekis paper in Room 381 on
Wednesday.
I should like to take this opportunity of
thanking all the speakers in this Session for their
keen interest and co-operation. The meeting
stands adjourned.
