The relationship between depth and age in the North Pacific Ocean by John Hillier, A.B. Watts

“…Using a thermal conductivity, k, of 3.138 mW m−2 as previous studies, however, gives a plate of similar thickness (i.e., thermal thickness, L, of ∼115 km) but one which is unreasonably hot (i.e., temperature at the base of the plate, Tb, of 1522 °C) and inexpansive (i.e., coefficient of thermal expansion, α, of 2.57×10−5 °C−1). …”
