Ron Schott and I agree that there are a lot of great geobloggers out there who are worth your attention.

Ron, however, has made a list.

Check it out. You're unlikely to find that every writer on that list is to your taste, but you're quite likely to discover someone just right for you, who you didn't yet know existed.

Washing into the sea

Madagascar is falling apart geologically and biologically.

Today, Soichi Noguchi posted a gorgeous picture of the mouth of a river in Madagascar, pouring mud into the sea with a design like an abstract painting:

FIRE! Madagaskar. Almost like an oil painting. on Twitpic

Sadly, that mud is flowing off the hillsides with every rainstorm, every one of Madagascar's not-infrequent cyclone hits, and blows off with the wind. Deforestation began in Madagascar with the first European colonization, and the demand for exotic wood (or any wood, eventually), and continued as slopes were cleared for agriculture. Between the general population of Madagascar, with people simply trying to get enough to eat, and shelter, and work, and the corporations driving the agriculture, it will be amazing if Madagascar can keep from dying, biologically, before any sort of control or balance is found.

Pi Day at the Exploratorium, San Francisco

I love dorks



I'm trying to find a way to connect this to geography, and struggling beyond circular lines of latitude slicing up the earth. I welcome ideas - because I couldn't resist the post.

To drink forever alongside Odin

I can't always figure out where Geography ends. Does it include our atmosphere? I think so. Magnetosphere? Why not?



Of course, astronomy fascinates me, too.

At any rate, the auroras are clearly in the zone where astronomy and geography overlap.

Astrospace Now has a great podcast discussing folklore about the auroras.

I've only seen an aurora once, and it was an Aurora Australis. I was at only 32.7 degrees south latitude, in South Australia -- very far north to see them. They oscillated and shimmered like a bright green gossamer curtain. I hope to see the Aurora Borealis this coming spring, when I'll be in Alaska.

... but not as we know it


Mono lakeshore
Originally uploaded by marymactavish.
Felisa Wolfe-Simon, a geobiologist, thinks Mono Lake may host "...alien life forms, or 'weird life'." She is investigating whether, in the mud or water, there live microbes "whose biological make-up is so fundamentally different from that of any known life on Earth that it may provide proof of a shadow biosphere."

Wow.

I love the Mono Lake basin because it's stunning and fascinating.

The Sierra Nevada rise along its western side.

Panum Crater, to the south, is a small volcanic cone a few hundred years old. When you hike up into it, first you walk over crunchy pumice, then over pieces of obsidian that tinkle underfoot like broken glass, making the thought of a stumble slightly nerve-wracking.

I once saw a Long-tailed Jaeger in a freshwater pond just north of Mono Lake. It's a pelagic bird that was lost ... or interested. Many species of bird feed on the brine flies at the edge of the lake. Eighty-five percent of California Gulls (the species, not the geographically-placed) breed here.

And Mono Lake plays an important role in the history of the environmental movement, its healthy future being the impetus for the Mono Lake Committee, one of the most effective and inclusive grassroots environmental movements in California.

But now, the possibility of parallel evolution? arsenic-based life? Mono Lake just gets cooler.

At least the birds got a few extra mud-critters for lunch

This covers the first two-thirds or so of a tsunami surge cycle at Point Loma, in San Diego. A small tsunami sloshed around the entire Pacific Ocean on February 27, 2010, in response to an 8.8 earthquake in Chile.

As much as that this video is nearly ten minutes long, I wish it had been longer. I'm not sure I'd want it edited, either -- I like the everydayness of it, the way people are talking to each other, and their wonder at the water.

I'm working on a bigger post about Chile, which I'll post in 12 hours or so.

The Mimic Octopus


Mimic Octopus
Originally uploaded by Daniel, Daniel Kwok.
Like everyone, I sometimes have days on which I do little but watch octopus videos:



This species, the Indonesian mimic octopus, was just discovered twelve years ago. It is fabulous.



It's known to mimic at least 13 different animals or corals, some of them deadly poisonous, though scientists admit they don't always know what they're seeing.





They're lost due to habitat degradation, fishing bycatch, recently even the pet industry.



It saddens and sometimes horrifies me that we can be doing such damage to species that weren't identified by scientists until our current crop of high school students was first learning to read.



I don't eat octopus, and I do what I can to help protect its habitat and the creatures in it. Biodiversity is essential, no species is completely expendable, but octopuses are just too damned cool to lose.

Frankly, I'm a little disappointed

Matt Rosenberg pointed out on twitter that the Einstein geography quote I posted (which I'd found on a university's geography department homepage, so trusted without thinking) was debunked: ".... this quote was actually written by Duane F. Marble, Professor of Geography at Ohio State University." The rest of the story is at the link.

I'm a little disappointed. It would have been an awesome thing for Einstein to have said.

"As I mentioned, Mr.President, Grand Canyon is breathtaking!"

Soichi Niguchi is way up on my list of all time favorte astronauts, if for no reason other than his sheer delight in photographing the Earth.

Geography's hard, let's do physics

Wallpapering with rocks and dirt

A huge chunk of my time for the past couple of days has been spent reinstalling Windows. It turns out that one can save a lot of time doing it right the first time --who knew? But I have a cranky old laptop, and only moderate computer skills (and a life, with other things to do), so I've been stuck with my old Treo for internet use for awhile.

While I was looking for interesting replacement wallpaper (eagerly anticipating a switch either to a Mac or to Windows 7, so I can rotate wallpaper -- decisiveness isn't my forte, I'd rather rotate nice wallpaper than have to decide) I stumbled on this neat blog I'd never seen before:
Geological Musings in the Taconic Mountains and today's relevant post, Geology Desktop Images.

I haven't yet poked around on it (still setting up my laptop) but will as soon as I've truly up and running.

Massive, impressive, slow-moving rockslide in Italy



Found at Rockglacier via Callan Bentley and Chris Rowan (or Mountain Beltway and Highly Allochtonous)

I don't speak Italian, but I imagine he's saying, "Holy cow, it's flowing like lumpy pudding!" Anyone have other details?

Snowing on blog ideas, or something

The internet is filling up with time-lapse snow photos from the east coast!



(Details on click through.)

I've got a whole list of geographile-seeds on my desktop here, and one hard post I'm working on, I want to explain the difference between climate and weather, and how climate change (or even global warming, gasp) could explain heavy-snow winters. I'm also working on the geography of the setting of one of my favorite book series, and exploring the relationship between HAARP and the Haiti quake - or the lack thereof.

What do you want to read about?

I love David Attenborough almost as much as I love sloths

snowpocalypse

The east coast of the United States is waking up to a world of snow today, after a record-breaking snowstorm.

A couple of people have posted a link to this image on twitter:



There have been no credits for it, nor precise locations, from what I can find. I'd love more information, both for credit and geographic specificity, if you know of any.

Sakurajima blowing ash

This post will be dated eventually, but at least right this minute, I can see ash erupting heavily out of the summit of Sakurajima on the live webcam: link here, in English, more languages available with clicky things at top right.

Sakurajima is a composite volcano, and used to form an island in a caldera, but in the past century, eruptive growth has joined it to the mainland.

Manzanita mandala


Manzanita
Originally uploaded by robherr.
I've written before about how much I love manzanita.

I want to learn to discern the various California species, but Pete Veilleux over at East Bay Wilds, who really knows his local native stuff, says it's a difficult task.

Among my classes this term are a couple or three that focus on local natural history. That should help.

Martin pointed out this gorgeous circle of manzanita leaves from Rob Herr, at Flickr. (He granted me permission to use the photo, it's not in the creative commons realm.)

The leaves are so beautiful and special. They're sclerophyllic, tough and a little leathery, to survive the hot, dry summers of their western habitats. The leaves chemically change soil to make it harder for competing plants to grow. And the colors, oh: they start so delicately green, and toughen to a darker green, turn reddish, then before they're gone, it's as if they self-immolate, without flames, they just dry and blacken. (They sometimes fall off before this stage, too, but it's weird, like someone's lit them.)

Their angle on the plant maximizes sun exposure when the sun is less direct and drying, in the morning and late afternoon, but minimizes it at midday, conserving moisture.

I love manzanita. Later, I'll write about the fire ecology around it and chaparral, and its magical bark, and what I want to do with the wood.

Howard Zinn, RIP - and he will

"We don't have to wait for some grand utopian future. The future is an infinite succession of presents, and to live now as we think human beings should live, in defiance of all that is bad around us, is itself a marvelous victory." -- Howard Zinn, August 24, 1922 – January 27, 2010

Howard Zinn was a great historian. I encountered him in high school, and if he did nothing else for me, he encouraged me not to take everything my textbooks said as the whole truth and end of the story, but to ask questions and think beyond curriculum. I've applied that to most of what I've read in academia and the media in the decades since.
