    About time - Antarctica
    From: Bruce J. Pennino
    Date: 2012 Mar 5, 10:50 -0500
    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.
