Ox Bow Lake Formation, As Seen By the Google Earth Time Machine

timothy posted about a year and a half ago | from the enhance-enhance-enhance dept.

Earth 50

djl4570 writes with a link to this "excellent study in the gradual change of geographic features as a river meander becomes an ox bow lake when the river current cuts through the meander. The same Google Earth feature can be used to view changes in urban and suburban geography. The historical data is a work in progress. The region I looked at only has images going back to 1993. Other regions will have a different mix and depth of data."

Happy Sunday from the Golden Girls! (-1)

Anonymous Coward | about a year and a half ago | (#40727657)

Thank you for being a friend
Traveled down the road and back again
Your heart is true, you're a pal and a cosmonaut.

And if you threw a party
Invited everyone you ever knew
You would see the biggest gift would be from me
And the card attached would say, thank you for being a friend.

...to high school geography!

This'll be a nice refresher, it was over 20 years ago and I don't remember a lot of it.

You can't remember due to of your love of paste.

Tastecicles (1153671) | about a year and a half ago | (#40728017)

um... nope, we used pens and paper notebooks.

This article should be fairly significant for me, as I live right on the neck of a meander of a major river.

I've plotted a graph of all the ox bow lake formations found using Google Maps, and guess what? Not one formed before 1993. What happened in 1993? That's right, CO2 levels hit 350ppm. Coincidence? I think not. We need to save our ox bows, donate today.

I don't know. I've been watching the moderation go from +1 to +2, then back down to +1, then back up....6 points spent on moderation so far. I wouldn't exactly call that a forum slide, but time will tell, I guess.

And besides, it's only a theory until evidence proves otherwise. What do you think I'm doing here? Looking for evidence.

Re:global warming-Testing (1)

Anonymous Coward | about a year and a half ago | (#40728179)

A "forum slide", as discussed in the document, can't happen on /.; it relies on typical vbulletin/phpbb/etc. software with independent non-branching threads, which are sorted by the time of the last post in the thread. /. has articles always sorted by the article's time, and posts within an article are sorted first by parent, with sibling posts further sorted by time and/or moderation score.

Re:global warming-Testing (0)

Anonymous Coward | about a year and a half ago | (#40728373)

With the new(ish) "Full/Abbrev./Hidden" settings, it would be fairly easy to bury something with a low moderation score and given the offtopic nature of the post, it's easy to mod to into oblivion (and keep it there) too.

The whole thing seems silly to me, though. For every forum, there is an anti-forum where the opposite moderations occur. Some form of groupthink seems the most likely culprit to me for perceived slights. No need to drag initialed agencies into it.

Re:global warming-Testing (0)

Anonymous Coward | about a year and a half ago | (#40730637)

There will always be some people who take moderation super seriously and browse at -1, sorted by post time. This is slashdot, after all.

And thanks for giving us examples of Rule #4 and Rule #5.

Re:global warming-Testing (1)

robthebloke (1308483) | about a year and a half ago | (#40728891)

Rule #4: Thou shalt not post a link to dancing hamsters on thou'st geocities page.
Rule #5: Thou shouldst use Altavista search, for it is the finest search engine there is.

Or have you hipsters been trying to instagram the original rules or something?

Re:global warming-Testing (0)

Anonymous Coward | about a year and a half ago | (#40728485)

Spamming, posting off topic, and trolling. These are the reasons these posts get modded down. It's not mind control, group control, group think, or whatever idiotic conspiracy you think it is. It's you being a shitty poster. Just accept it. Own up to it. Either post better or stop posting and move on with your life.

I realize not everyone cares a whole lot about web design; but who the heck puts black text on a dark blue background and doesn't immediately notice it's awful for reading?

Aliens. Or the Welsh. The Welsh are a bunch of cunts.

Apparently a Texan geology student.

He probably hasn't even noticed that it is hard to read. The twitter generation doesn't bother to read their post anymore.

Re:My eyes, they hurts (1)

Anonymous Coward | about a year and a half ago | (#40727915)

I make sites just like this on purpose to troll the friends that I do have who are web designers. Only takes a few minutes with a wordpress install and some themes, then I just customize them to have horrible text/bg color combos such as black/brown, red/orange, etc

Owner of the blog here. I follow the sources of my traffic back to their origins and I'm sorry the text bothered you. I've fixed it. However, your witty remark comes with a price. You owe me your eyeballs.

You can view that in the cinema right now.

Scratch
Full disclosure: I was in the movie

In the Science museum in Paris they have a wall with a crack that was closed when the museum was opened. They move the walls apart over the years by the same distance that Europe and America drift apart. There was quite a wide crack when I was there many years ago. By now you must be able to walk through it quite easily.

Whuh...? WTF does a film about hip-hop [imdb.com] have to do with plate tectonics?

Re:Wait a few million years (4, Informative)

Zontar The Mindless (9002) | about a year and a half ago | (#40727981)

Over the course of your lifetime, Europe and America will have drifted about 20 feet further apart.

(Best estimate seems to be 5-10 cm/yr [uc.edu]. Split the difference and multiply by 75 years; that's about 5.6 metres.)

Is that an American car length or a European car length?

US 70s oldsmobile. I think the conversion in PI*USOlds=Eurocars...i may bo off by a factor of 2 though.

Re:Wait a few million years (1)

Anonymous Coward | about a year and a half ago | (#40729733)

Plate motions world-wide range from under 1cm/year to about 14 cm/year maximum at the present time. Across the Atlantic it depends upon where you measure the spreading, because along any plate boundary the rates of motion will inevitably vary (it's a feature of motion on a spheroid), but the Mid-Atlantic Spreading Ridge is generally a fairly slow spreading ridge. 1 to 4 cm/yr relative spreading rate is typical. Between North America and Europe is probably 2-3 cm/yr, depending on which path you measure across.

images going back to 1993? (0)

Anonymous Coward | about a year and a half ago | (#40728171)

The first image in TFA is an aerial photograph from 1945. Google Earth incorporates some maps from a long time ago: "... Google superimposed old woodblock prints of maps from 18th and 19th century Japan over Japan today." http://en.wikipedia.org/wiki/Google_Earth [wikipedia.org]

The amount of information incorporated into Google Earth is mind boggling.

Google Earth Time Machine? (0)

Anonymous Coward | about a year and a half ago | (#40728501)

I was skeptical until I saw the first image was from 1944. Wow, I hope you guys at Google patented this one.

Ox Bow Lake Formation as SHOWN by Google Earth. It's a simulation, folks.

Map view doesn't show the cut-through (2)

IcyHando'Death (239387) | about a year and a half ago | (#40729047)

The blog provides the coordinates, 2915'34.29"N 09534'08.85"W, so you can view the formation on Google maps. If you check it out in map view [google.ca], it still shows the original river bend with no cut-through.

Emergence (1)

BonThomme (239873) | about a year and a half ago | (#40729853)

Ox Bow Lakes blew my mind in junior high. I didn't realize it at the time, but it was my first introduction to emergence, long before anyone was talking about emergence.

Billabong for our "Down Under" friends (3, Informative)

Red Storm (4772) | about a year and a half ago | (#40730407)

Just in case our "Upside down" compatriots in Australia are confused about an Ox-Bow lake, you would know them as a Billabong, yes body of water that the Swagman boiled his billy by and ultimately jumped into is real...
