Enter temperature and salinity to find density σt.
Enter temperature, salinity and pressure to find in-situ density σStp.
|Note: 10 kPa = 1 dbar is close to the pressure increase that corresponds to a depth increase of 1 m.
Entering a pressure value equal to the depth in metres will give an approximate result.
Add 1000 to the result to obtain density in kg m-3.
Temperature uses IPTS-68, salinity uses PSS-78; see reference.
