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
