I can only talk about rocks...

Today, most of what I did consisted of understanding the cartographic symbology of symmetrical and asymmetrical anticlines and monoclines.

I'm afraid that's as exciting as it gets.

As it happens, Nomad, you don't only write about rocks, you write brilliant personal-experience diaries about your life in Jo'burg. ;)

What looks like a nice example of abstract art to  brighten a dark evening for most of us, while Nomad might understand the accompanying text :-)

turbulence-s



Visualized Turbulence (Image 2) The distribution of vorticity in developing Mach 1 turbulence, as computed with the PPM gas dynamics code on the TeraGrid cluster at the National Center for Supercomputing Applications (NCSA) in 2003 using a computational grid of over 8 billion cells. This series of images shows the vorticity as it evolves through the transition of fully developed turbulence. The vorticity, which measures the amount of shear in the flow, highlights thin surface-like regions in the flow across which the flow speed changes very rapidly. Later in the development of the turbulence, these sheets of vorticity roll up to form a large number of vortex tubes or filaments, which, especially given the high flow speeds here, are somewhat akin to tornadoes.

(I Am Not A Material Scientist)

But I was reminded of:

[minstrels] Big Whorls Have Little Whorls -- Lewis F. Richardson

Big whorls have little whorls
That feed on their velocity,
And little whorls have lesser whorls
And so on to viscosity.

I posted a history of that poem here.

But you kinda knew that. Nice bubble verse BTW.

At least a glaring error gets you commenting. Still travelling?

At least rocks have a life...

On a serious note, an alike proposal has been made by one of the more controversial professors (Schuiling) of my former university. Last year, if I recall, he went to Turkey to see how feasible it would be to create peridotite pebble beaches - beaches and saline water would be a good spot to enhance chemical weathering. Don't know how that ended, but I'll find out during my Christmas break - a friend of mine came along. Schuiling's name pops up here and there on the web.

Limestone was laid down in shallow seas, at least partly as a product of the life cycle of plankton. The shells of the dead plankton and other marine life fall to the sea floor, and, under the right conditions, get converted to limestone.  This process was likely a major factor in the long term reduction of the amount of atmospheric CO2.  

But the process is neither simple nor straightforward. This is why "seeding" the ocean with iron oxide to cause a plankton bloom is an uncertain longtime means of capturing CO2.  Limestone deposits are often found in alteration with shale deposits.  That would seem to indicate that the process turns on and off.  That, in turn, might enable some insight into how to cultivate this process on a geologic scale.

Perhaps the melting of polar ice caps will result in the creation of new shallow seas which will turn this process back on.  That solution is likely to be rather slow from a human perspective, but that might not matter---in the long run.  Nomad should be able to amplify and/or correct this comment.

As the Dutch said while fighting the Spanish: "It is not necessary to have hope in order to persevere."
