Calculation for salinity
Salinity (% wt.)= 1.76958Tm-4.2384*10 -2 Tm 2 + 5.2778*10 -4 Tm 3 (Potter et al.,1978)
Salinity (% wt.)= 1.78Tm - 0.0442Tm 2 + 0.000557Tm 3 (Bodnar, 1993)
Calculation for isochores (Zhang and Frantz, 1987)
P=A 1 +A 2 T
A 1 =6.100·10 3 +(2.385·10 1 a 1 )T h (2.855·10 3 +a 2 )T 2 h (a 3 T h +a 4 T 2 h )m
A 2 =a 1 +a 2 T h +9.888·10 6 T 2 h +(a 3 +a 4 T h )m
