TEOS-10 Software: Use It Or Lose It

Where Will We 'B'

I. It Bears/Bares Repeating

 Over the years I have pointed out that Dredd Blog uses the TEOS-10 software library for calculations based on the World Ocean Database (WOD) data (e.g. Golden 23 Zones Meet TEOS-10, 2017; The World According To Measurements - 10, 2018; On Thermal Expansion & Thermal Contraction - 42, 2019; On Thermal Expansion & Thermal Contraction - 44, 2020).

I have also pointed out that the TEOS-10 is historically based on the work of Josiah Gibbs (e.g. The World According To Measurements - 12In Search Of Ocean Heat - 5).

I have not been shy about how important the work of Gibbs was and is:

"Listening to Gibbs, who is perhaps the most influential historical voice in ocean thermodynamics (encapsulated in TEOS-10) would also help:

"Albert Einstein called him 'the greatest mind in American history.' Gibbs’s studies of thermodynamics and discoveries in statistical mechanics paved the way for many of Einstein’s later discoveries."
(American Physical Society). Especially since "encapsulated" means:
"TEOS-10 is based on a Gibbs function formulation from which all thermodynamic properties of seawater (density, enthalpy, entropy sound speed, etc.) can be derived in a thermodynamically consistent manner."
(Thermodynamic Equation Of Seawater - 2010, emphasis added). Or they can continue to flop around like the scientists who forgot about gravity in the ocean realm, as pointed out by Woodward 1888; scientists who therefore could not figure out some major variations in sea level change (NASA Busts The Ghost)."

(In Search Of Ocean Heat - 5). TEOS-10 is a tool, not a toy.

II. Be Modern

The modern TEOS-10 software toolbox, however, is the result of the work of live scientists, and if you use it please follow their request: "If you use the GSW Oceanographic Toolbox we ask that you include a reference to ...

'McDougall and Barker (2011), whose full citation is:
McDougall, T.J. and P.M. Barker, 2011: Getting started with TEOS-10 and the Gibbs Seawater (GSW) Oceanographic Toolbox, 28pp., SCOR/IAPSO WG127, ISBN 978-0-646-55621-5'"

(TEOS-10 Software). The TEOS-10 website supports that software library with a comprehensive explanation of the underlying oceanographic concepts involved (The Gibbs SeaWater ... Oceanographic Toolbox of TEOS-10).

The main gist of the requirement to use high-energy, high-speed computer software libraries is the quantity of data.

III. Get Up To Speed

I have pointed out that Dredd Blog uses ~5.5 billion in situ measurements to generate graphs and other data for users to peruse (WOD Update). 

Processing one measurement per second would take 91,666,666.67 minutes, which is 1,527,777.78 hours, which is 63,657.41 days, which is ~174.3 years.

Take the Dredd Blog advice and use a computer (mine processes this data in a few seconds).

IV. Use It Already

Use TEOS-10 and a worthy computer or lose touch with the world according to measurements.

Don't be like 'laid back Francois' in the video below, or the seaports will already be under meters of water before you complete your white-board calculations (Seaports With Sea Level Change, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12).
