"Underwater" library music c.1969

Via the Toys and Techniques blog, Franco Potenza's "Vita e lavoro nell'acqua" ("Life and work in the water"), c.1969, is a beautiful example of library music meant to accompany underwater-themed visuals. In the media business, library music is music that's usually owned outright by a company and then licensed to customers who use it as soundtracks for TV shows, radio programs, and industrial films. There's still a wealth of amazing vintage library music warping away on vinyl in warehouses, basements, thrift stores, and record shops around the globe awaiting rediscovery by intrepid crate-diggers.

Scientists unearth ancient water in Virginia

Researchers taking a core sample of sediment beneath Cape Charles, Virginia, found something surprising sandwiched between the layers of mud and ooze. Locked inside a rocky layer 5000 feet down, they discovered water — water from the early Cretaceous period. Read the rest

The Great Sahara Sea

In the 1870s, a French geographer proposed digging a canal from the Mediterranean to flood a low-lying part of the Sahara Desert. He pitched it as good for business and good for local environments, writes Ron Miller at i09. But I can't help but think of Plagues and Pleasures of the Salton Sea — a documentary about the development, culture, and slow, ongoing destruction of a salty, inland sea that accidentally formed in southern California in the first part of the 20th century.

Drowning without a sound

Drowning, in real life, doesn't look or sound the way it does on TV. It's not loud. It's not thrashy. And it can happen just a few feet away from you without you even noticing. At Slate, Mario Vittone explains the Instinctive Drowning Response — a physiological knee-jerk reaction that pretty much prevents all the signs and signals most of us look for in order to identify a person in the water who needs help.

More evidence linking fracking wastewater disposal to earthquakes

Here at BoingBoing, we've talked before about the fact that earthquakes can be triggered by things humans do — everything from building particularly large reservoir to, most likely, injecting wastewater from fracking operations into underground wells. After a 5.7 earthquake hit Oklahoma in 2011, researchers there began gathering evidence that is making the link between rumbling earth and oil-and-gas discovery a lot stronger. At Mother Jones, Michael Behar has a story about this research and and how it is (and isn't) affecting the industry. Read the rest

An appreciation of the Sawfish, one of Earth's most threatened fish

"The earliest sawfishes likely arose in the shallow Tethys Sea, that ocean surrounded by the ancient continents of Godwanda and Laurasia, during the Cretaceous period at least 60 million years ago," writes Dr. M. at Deep Sea News.

These "sole survivors of an ancient bloodline" now number only seven species which roam the muddy bottoms of coastal areas, bays and estuaries. 

All sawfishes can move easily between fresh and saltwater and often venture deep upstream into rivers. The sawfish lifestyle puts this both their size and saw near humans.  All seven species are considered critically endangered by the IUCN.  As much as we have impacted them, sawfish have also greatly influenced our culture.

And now, they're one of the most threatened species on our planet. Thanks, humans!

The art and science of searching for water

The United States Geological Survey has an interesting FAQ report on dowsing — the practice of attempting to locate underground water with divining rods. It's got some interesting history and comparisons between dowsing and modern hydrology. The part on evidence for and against dowsing, though, is pretty sparse. If you want more on that, The Skeptic's Dictionary has some deeper analysis. The basic gist — what little research there has been suggests the successes of dowsing aren't any better than chance. (Via an interesting piece by Mary Brock at Skepchick about dowsing in the wine industry.) Read the rest

Clean rivers: A 20th/21st century miracle

I was born in 1981 and, because of that, I largely missed the part of American history where our rivers were so polluted that they did things like, you know, catch fire. But it happened. And, all things considered, it didn't happen that long ago. The newspaper clippings above are from a 1952 fire on Ohio's Cuyahoga river. Between 1868 and 1969 that river burned at least 13 times.

That's something worth remembering — not just that we once let our waterways get that trashed, but also the fact that we've gone a long way towards fixing it. We took 200 years of accumulating sewage and industrial degradation and cleaned it up in the span of a single generation. At Slate, James Salzman writes about that reversal of environmental fortune, a shift so pronounced — and so dependent upon a functioning government in which a diverse spectrum of politicians recognize the importance of investing in our country's future — that it seems damned-near impossible today.

... discharging raw sewage and pollution into our harbors and rivers has been common practice for most of the nation’s history, with devastating results. By the late 1960s, Lake Erie had become so polluted that Time magazine described it as dead. Bacteria levels in the Hudson River were 170 times above the safe limit. I can attest to the state of the Charles River in Boston. While sailing in the 1970s, I capsized and had to be treated by a dermatologist for rashes caused by contact with the germ-laden waters.

Canadian Conservative govt guts protections for 99+% of waterways, spare handful of lakes with high-cost cottages

The wild rivers above California

Atmospheric rivers are meteorological phenomenon that we humans only discovered in 1998 and which supply about 30-to-50 percent of California's annual precipitation. In the NOAA satellite image above, the atmospheric river is visible as a thin yellow arm, reaching out from the Pacific to touch California. Or, more evocatively, reaching out to slap California silly with a gushing downpour.

An atmospheric river is a narrow conveyor belt of vapor about a mile high that extends thousands of miles from out at sea and can carry as much water as 15 Mississippi Rivers. It strikes as a series of storms that arrive for days or weeks on end. Each storm can dump inches of rain or feet of snow.

The real scare, however, is that truly massive atmospheric rivers that cause catastrophic flooding seem to hit the state about once every 200 years, according to evidence recently pieced together (and described in the article noted above). The last megaflood was in 1861; rains arrived for 43 days, obliterating Sacramento and bankrupting the state.

As you might guess, climate change is also involved. Evidence suggests that warming global temperatures could increase the frequency of atmospheric rivers. That, combined with the 200-year event expected soon and the fact we're learning so much much more about these storms, means that you should expect to hear the phrase "atmospheric river" more often.

Scientific American has two interesting stories on the phenomenon right now. The first, which I quote from above, is a blog post by Mark Fischetti. Read the rest

A "not insignificant" defense of gleeful scientists

Just a few minutes ago, researchers with NASA's MESSENGER mission announced the publication of data that strongly suggests the poles of Mercury contain significant quantities of frozen water.

On the one hand, this is not exactly new news. The possibility of water on Mercury has been a topic of research for something like 20 years. And scientific discoveries tend to move in little mincing steps, not giant leaps, so there have been lots of previous announcements about evidence supporting the hypothesis of water of Mercury — including very similar announcements from the MESSENGER team in December 2011 and March 2012. Your life will not change in any significant way because there is frozen water on Mercury. You probably won't even make a note to tell your children where you were the day NASA announced that ice most likely existed there.

But that doesn't mean this news isn't damned exciting. And it doesn't mean that the scientists involved shouldn't be giddy about it. We are, after all, talking about a mission that sent a spacecraft into orbit around another planet and has quite likely found frozen water sitting on a landscape that is hot enough to melt lead. What's more, they think that ice is covered in places by a thin layer of some coal or tar-like organic material. That is huge news. It's going to change textbooks. And because the scientists think both the ice and the organic material got to Mercury via collisions with asteroids and comets, it's going to be an important part of our ongoing efforts to understand how life begins on planets like Earth.
