7 Appendix C - Calculated Parameters

The AML-3 instrument has the ability to calculate certain parameters depending on your sensor
configuration. Below is a table outlining the parameters that can be calculated.

Parameter

Required Sensors

Equation

Range

Salinity

C, T, P

Practical Salinity Scale 1978

0 - 90 PSU

1

Salinity (from SV)

SV, T, P

AML

0 - 90 PSU

Density

C,T, P

TEOS10

0 - 2000 kg/m

3

Density (from SV)

SV,T, P

TEOS10

0 - 2000 kg/m

3

Sound Velocity*

C,T, P

Chen & Millero

0 - 3000 m/s

Depth

P

UNESCO

-20 - 12000 m

C - conductivity, T- temperature, SV - sound velocity, P- pressure

1 - Instrument will report 0-90 PSU, however PSS-78 equation is valid only from 2-50 PSU.

*Calculated salinity must be enabled for the calculated Sound Velocity to operate correctly
