FigurJ! 4.3. Bathymetric map (1975) of Mirror Lake, West Thornton, Grafton county, New
Hampshire. Contour intervals in meters.
Table 4.5. Equations for linear and volumetric expansion of ice:
Linear expansion:
1, = 1.,(1 + at)
where I, = length a t t-c, 10 = length at ouc, a = coefficient of linear expansion. a nd 1 = temperature in C.
Volume expansion:
v, = Vo(l + (it)
where V = volume at tUC and O°C, and fJ = coefficient of volumetric expansion.
