2012 Annual Report - Jesus College - University of Cambridge

42 MEMOIR I Jesus College Annual Report 2012
reveal that he was dismayed to see that
something must have gone wrong with the
calibrations; my ozone values were just too
low. They picked up to some extent as the
summer advanced but the values were still
lower, and the overall seasonal variation was
different, from that observed in Spitzbergen
at similar latitude in the north.
Observations in the following few years at
Halley Bay confirmed that, in October in
particular, the values are abnormally low.
You heard it first here. We had to wait until
the 1980s before the full global picture
appeared, showing the ‘ozone hole’
expanding from Antarctica, and later, a
similar process beginning in the Arctic.
The expedition achieved all the objects set
out in the RS plans, on time, and without
loss or damage to persons or goods; 90%
of the credit for this goes to David
Tottan alongside the fast ice
Dalgliesh and much of the remainder to
George Lush.
There were to be two relief ships bringing
in the main party of 20 men in January 1957:
their stores were on the faithful Tottan
with Lief Jacobsen but the personnel were on
the MV Magga Dan (on its maiden voyage),
along with the main party of the Trans-
Antarctic Expedition and their stores.
Our loyalties were with the Tottan so we were
pleased that she arrived first, but pleased also
to have the Danish cuisine for the voyage
home, arriving in the pool of London in
March 1957.
In 1959 I came to the Polar Institute in
Cambridge. During the following 14 years
I made four visits for glaciological
explorations in the Arctic and three more
in the Antarctic – but no more overwintering.
