Sea-Floor Sunday #4: Structural deformation revealed off the coast of California (repost)

November 18, 2007

Deadline. Quickly. Approaching.

No time for a new post…but, here’s a rerun from several months ago.

A great web resource if you are interested in marine science in California is SIMoN, which stands for Sanctuary Integrated Monitoring Network; it is a portal for all things related to the Monterey Bay National Marine Sanctuary. Much of the site involves the biological and habitat aspects (it is a sanctuary after all) but there is also great stuff regarding the geology and geomorphology of the area.

The image below (see page on SIMoN here for all the details) is from an area offshore of the central California near Half Moon Bay (just south of San Francisco and north of Santa Cruz). This area is called Mavericks and is a popular surfing spot.


What is most striking is how nicely the structural deformation of Pliocene sedimentary rocks is shown with this image. Movement on the San Gregorio fault (a wholly owned subsidiary of the San Andreas) has produced this folding and the layered nature of the strata has resulted in the differential erosion and alternating ridges and ‘valleys’ seen on the bathymetry.

And check out this little fly-over movie too (if movie is not embedded, go here).

    That’s very cool. (Especially for someone who has TA’d at Half Moon Bay!)

    So, when you’re done with the defense, you’ll come and post a big woo-hoo, right?

    I thought you’d like that image.

    I’m in the process of printing out the dissertation for the committee to read…my defense is still a couple weeks away. But, I am happy to be done writing (for now).

    Congratulations on having a complete draft! That’s worth celebrating, even if you know that the committee will have plenty of things that they want you to change.

    To a complete draft!

    *clinks glass*

    Well…almost a draft…I am still working on the intro to the whole thing…and the table of contents, list of figs, etc.

    but, i’ve started celebrating just a little with a nice glass of carmenere – *clink*

    You know that Word has a table-of-contents generator, don’t you? Using heading styles? It’s saved some of my thesis students some very painful editing when their first attempt didn’t conform to official institutional rules. And it works for lists of figures, too.

    I don’t know if I would be able to find it in Office 2007 for PC. I could probably figure out where it is on the most recent version for Mac.

    yeah…the ToC isn’t the problem…now, it’s trying to summarize three separate projects that are within a theme, but use very different data and address very different scales…so, trying to come up with an eloquent way to express that is escaping me…i’d actually rather work on the ToC right now, that’s more mechanical :)

    or, I’ll just drink another glass of wine

    Please don’t tell me you’re using Word…

    unfortunately, yes … i am not that enlightened when it comes to word processing options

    Carmenere is good stuff. It has an animal edge to it, and a flavor that reminds me of dried ancho chilies. Kind of an unshaven pinot noir, full of interest.

    A wholly owned subsidiary of the San Andreas – never heard a corporate analog like that to describe geology. It works… painfully… but it works.

    So who produces a good “carmenere”?

    I got into carmeneres working down in Chile…it is a popular varietal down there. I’m starting to see it more and more in the States now … the one you’ll see a lot (at least here in California) is Casillero del Diablo. It might not be the best of the best, but I like it and it’s relatively cheap ($8). I’m of the opinion that one rarely needs to spend more than $10-15 for a decent bottle of wine. Or, next time you treat yourself to a fancy dinner, see if they got one on the wine list.
