Abstract : Observations made in and along the shores of the Connecticut River, near Hanover, New Hampshire, showed that the water temperature decreased from +14C on 23 October to +3.5 degrees on 21 November 1968. The river froze over on 10 December 1968 and the ice water cover midriver was 9 to 11 in. thick on 16 January 1969. The water temperature beneath the ice sheet decreased from 2.3C to 0C just below the surface between 4 and 18 December 1968 and remained so down to a 15-ft depth until observations ended on 22 January 1969. These persistent near-freezing temperatures in the river were attributed to mixing caused by the constant flow of water beneath the ice sheet. (Author)
