Interesting article about seawater chemistry

[bblumberg]

A multinational study overturns a 130-year old assumption about seawater chemistry

There's more to seawater than salt. Ocean chemistry is a complex mixture of particles, ions and nutrients. And for over a century, scientists believed that certain ion ratios held relatively constant over space and time.

Interesting. Now I'm curious about what the exact Cal and mg levels are in the different tested places and depths...

Here's the actual paper. I'm too tired to look at it right now, but the data seems to be publicly available:

Global variability in seawater Mg:Ca and Sr:Ca ratios in the modern ocean

Seawater elemental composition, namely Mg:Ca and Sr:Ca ratios are widely used in marine sciences. Our new single-laboratory global dataset, combined with past data of seawater Mg:Ca and Sr:Ca ratios, suggests that modern ocean variability is significant across different environments, being...

I'm more than willing to assume it probably scales with the currents though....

I just wish the data wasnt in micomoles too bad it wasnt ppm. Those scientists and their micromoles! Dont they know reefkeeping is everything? Jk

μM .....

jokes aside, parts per million just translates to mg/L, which does require some stoichiometry, but that's not hard once you get it down. Quite frankly, I wish that the world would just pick a system and stick with it. Too much dKH this, and ppm that. I just want everything in moles, since that's what we're taught in high school....
