This paper and associated software implement the
Thermodynamic Equation Of Seawater – 2010 (TEOS-10) in Excel for an
efficient estimation of Absolute Salinity (SA), Conservative Temperature
(Θ), and derived thermodynamic properties of seawater – potential
density (σΘ), in situ density (ρSA,Θ,p), and sound speed (c). Vertical profile template plots
for these parameters are included as is an SA–Θ diagram
template, which includes plotting of the density field (computation
of user-selected σΘ lines is included). Absolute Salinity
can be directly measured with the aid of a densimeter (IOC, SCOR and IAPSO,
2010: p. 82), but in TEOS-10 its estimation relies on the interpolation of data
from casts of seawater from the world ocean (IOC, SCOR and IAPSO, 2010), and
the Excel workbook introduced here (TEOS-10 Excel, available at
https://doi.org/10.5281/zenodo.4748829) includes a subset of the TEOS-10
look-up tables necessary for this estimation, namely the Absolute Salinity Anomaly [deltaSA_ref] and the Absolute Salinity Anomaly Ratio
[SAAR_ref] look-up tables. As the user simply needs to paste
new data into the spreadsheet to automatically compute the oceanographic
parameters referred above, t...
