Yes I heard of the Signy extra winter. From my memory the guy had done 2 winters at Halley and was dropped off at Signy to do some work. The ice closed in and he was not able to be picked up to head north. During my time there was always talk fo double pay if you had to do a 3rd winter...... Pitty it was not true. Keep up the good work.
Wintered at Rothera 92,93. And wintered at Halley 94. Now live and work Turkey looking after privat yachts.
