Double the trouble — a poem about double-diffusive mixing in the ocean

On my blog’s fourth Birthday (!!!), it’s time to try something new. How about some celebratory oceanographic poetry? Obviously the topic has to be my oceanic pet process, double-diffusive mixing

 

Double the trouble

Heat mixes by molecules bumping
into each other and clunking
momentum transfers
so fast it all blurs
the warmer the faster they’r’all jumping

A different story for salts
where ions — through not their own faults!
must change their location
which leads to palpation
resembling a fairly slow waltz

Now heat and salt mix simultaneous
-ly without ‘ny extra extraneous
stirring or shaking
fish swimming, waves breaking,
which leads to effects miscellaneous

The ones I like best are salt finger:
structures that form and then linger,
tricking unsuspicious
oc’nographers vicious
-ly into assuming not threat to the thinker

This process includ’d in simulations
leads to much better foundations
of climate prediction
that is my conviction
you can read here* about the causations

Not only the currents o’the ocean
that consequently change their motion
but also biology
chemistry, geology
and last, not least, atmospheric transpos’tion

To sum up, this double diffusion,
those fingers that are no illusion
when climate has changed
the ocean’s been deranged
def’nitly deserve an inclusion :-)

 

 

Happy Birthday, my little blog! :-)
