Just finished reading The Storied Ice by Joan
Boothe. A very good overview book about all major explorations
of Antarctica; many references.
Anyway, Antarctica explorers had a longitude
problem. In 1926-27 the Discovery "was the first vessel in these waters capable
of receiving Greenwich time signals directly, and her men used the signals to
check longitudinal positions on the maps." Only Deception Island was
properly located.
Also,as the early explorers headed south ,they
measured water depth for various reasons. How did they measure depths of several
thousand feet with a drifting ship, angle of cable,
flexibility(springiness)?
Boothe gives a brief overview of Cook's
explorations....she says he was an extraordinary man.
