TEOS-10 Seawater Conductivity

Calculate TEOS-10 seawater conductivity from pressure, temperature and practical salinity.

Practical salinity is measured by comparing the sea water conductivity with a reference conductivity.

To convert pressure: 1 MPa = 100 dbar (deci bars) or 1 dbar = 1e4 Pa. To convert conductivity 1 S/m = 10 mS/cm.

CALCULATOR : TEOS-10 Seawater Conductivity From Pressure Temperature And Practical Salinity [FREE]   ±

Calculate TEOS-10 seawater electrical conductivity from temperature, pressure, and practical salinity.

Check electrical conductivity C = 4.359895 S/m for T = 15 C, P = 3 MPa, and SP = 35.5 parts per thousand.

To convert pressure: 1 MPa = 100 dbar (deci bars). To convert conductivity 1 S/m = 10 mS/cm.

Tool Input

  • T : Seawater Temperature
  • P : Seawater Pressure

Tool Output

  • C : Electrical Conductivity
CALCULATOR : TEOS-10 Seawater Hydrostatic Pressure From Water Depth [FREE]   ±

Calculate TEOS-10 seawater hydrostatic pressure from water depth or relative elevation.

The submerged pressure is calculated using Bernoulli's equation. Elevation is measured relative to an arbitrary datum (+ve up -ve down). Mean sea level (MSL) is often used as a datum. The water density is assumed constant. Changes in water density with water depth, salinity and temperature are ignored.

Tool Input

  • pletype : Pressure Type
    • Zlu : User Defined Submerged Elevation (+ve up -ve down)
    • wdu : User Defined Water Depth
    • Pu : User Defined Pressure
  • Zs : Surface Elevation (+ve up -ve down)
  • ρ : Seawater Density

Tool Output

  • P : Seawater Pressure
  • Zl : Submurged Elevation (+ve up -ve down)
  • wd : Water Depth
