A #scipoem on upwelling of tropical OMZ waters in a warmer climate

“Simulated reduction in upwelling of tropical oxygen minimum waters in a warmer climate”*

Let’s pick apart this article’s title,
inaccessible to most people out there.
Even though we know it as vital
to communicate clearly, be able to share,
what goes on in iv’ry towers detrital,
to whom it is relevant, as well as where.
Since taxpayers pay for us, science and all,
we need to inform them without any brawl.

“Sim’lated” just means a model predicts.
“Warmer climate”, then, is scientists’ code
for “some time in the future”, but nothing fix.
Which means if we continue down this road
of putting more CO2 in the mix
“upwelling”, whatever that is, will be slowed.
“Upwelling” means that waters from the deep
up to the surface of the ocean creep.

“Tropical” means “going on in the tropic’”.
“Oxygen minimum waters” contain
low levels of oxygen, which are a topic
of discussion in the science domain,
because if levels sink down to “hypoxic”,
almost no life in the sea can remain.
Fate of dead animals and plants, in the end,
does on the oxygen levels depend.

Dependent on oxygen, chemicals form,
that can change climate as does CO2,
if they reach the atmosphere in a storm
or just by “upwelling”, out of the blue,
they make that further the climate will warm.
Therefore, it’s nice to know that the brew
of “oxygen minimum waters” will leach
more slowly to continents’ western beach’.

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! :-)
