Have you ever wanted to hunt for meteorites in the Great Lakes using underwater robots? Yes? Well, guess what? Now you can! Join along with the ROV Meteorite Hunt on OpenExplorer!
If the Great Lakes are a little too chilly for you, maybe consider joining SFS Super Fan Joey Meier and his students at Polk State on their journey to Guadalupe!

Dear John: Farming and technology in the near future.

March 29, 2017March 29, 2017 Andrew Thaler

Popular Culture

I wrote this story a couple of years ago and have been trying to find a home for it ever since. As the issue of proprietary software’s relationship to agricultural technology is back in the news, I figure it’s time to stop shopping this short science fiction story around and put it in front of a real audience. For some real-world background reading, see:

DEAR JOHN.

It started with the tractor. Or, rather, it stopped with the tractor. John Willis climbed down from the cabin of his dead machine and removed the cowling. Everything looked fine. The diesel engine shined, its green accents still brilliant.

After years trading his skill with a wrench and a soldering iron for access to his neighbors’ equipment, he finally owned a tractor of his own. The latest model, too. Not ostentatious, but with just enough comforts to make up for the last ten years. The tractor was new, bought debt-free through the Farm Act and a decade of careful planning and backbreaking labor. Expensive, but built to last.

Except it didn’t last. For the third time in an hour, the engine seized, the wheels locked, the console went dead. Willis sighed. He had acres to till and he wasn’t in the mood to spend a day stripping the engine, hunting for some tiny defect. He could send it to the service yard, but he couldn’t afford to wait for an authorized repair. The quote alone would set him back a week.

He couldn’t afford another late planting. Not this year.

He started the tractor. It roared back to life, the engine purred but the console beeped and flashed with panic, a thousand different alarms. The manual, a massive, multi-gigabyte document, was sitting on his work computer, back in the barn. For whatever reason, he couldn’t get it to download to his field tablet. He put the tractor in gear and continued down the field.

Fifteen minutes later, the tractor was dead again.

Well, he thought to himself, at least there’s a rhythm to it. He limped down the rows in quarter-hour bursts.

Building the future with open hardware. Monday Morning Salvage: March 27, 2017

I spent the last week at the annual Gathering for Open Science Hardware in Santiago, Chile exploring the future of science and the open-source movement with one of the most impressive hardware developers, hackers, makers, and artists in the world. It’s my travel day, so this will necessarily be a short one.

Among the many things still blowing my mind? 3D printing in steel using a MIG welder. So simple, so clever, so brilliantly implemented. See the paper below.

Scientists deploy satellite tags on rarely studied sawsharks for the first time

March 23, 2017March 23, 2017 David Shiffman

Science

An Australian research expedition has successfully deployed three satellite telemetry tags on sawsharks for the first time! These rarely-seen sharks have a toothy rostrum similar to a sawfish, but are true sharks while sawfish are rays. Sawshark rostrums also have sensory barbels, unlike the rostrums of sawfish. “This is actually a good example of convergent evolution where two distantly related species have adaptations that have converged to be very similar in looks and (purportedly) function,”said professor Jane Williamson, the head of the Marine Ecology Group at Macquarie University and the leader of this expedition. “Sawsharks probably use their rostrum in a similar manner to sawfish: as a tool for sensing and capturing prey, and possibly for self-defense.”

The poetry of Derek Walcott.

Nobel laureate, poet, and perhaps the finest English-language writer of any generation, died this weekend. His poetry, particularly the epic poem Omeros, which draws upon the themes of Homer’s Iliad and Odyssey to tell the story of colonization, imperialism, slavery, and humanity’;s relationship to the sea over more than 8000 lines.
If you’re new to the poetry of Derek Walcott, The Sea is History is a great place to start and the New York Times published a short selection of his poetry: The Pages of the Sea.

Please don’t ride sharks, and other great tips from the new guide to responsible shark diving

March 12, 2017March 13, 2017 David Shiffman

Conservation, Science

Shark wildlife tourism* is a growing marine industry with big implications for shark conservation. While there are many competing definitions, generally shark wildlife tourism refers to SCUBA dive operators who offer trips that guarantee that you’ll see sharks, often through the use of bait or chum to attract sharks to the divers. This has become a contentious issue in marine science and conservation circles. That’s why last week’s news that WWF, Project AWARE, and the Manta Trust released the first-ever guide to responsible shark and ray tourism best practices is so welcome. This thorough and well-researched guide guide is designed for dive operators who want to minimize their potential harm to sharks and rays while maximizing the potential conservation benefits of shark wildlife tourism.

The call of the Chthulucene ?

March 9, 2017March 9, 2017 Chris Parsons 1 Comment

Climate change

We are currently in the Holocene epoch, and many of us have heard about calls to name the current era (from the industrial revolution) the Anthropocene (which dates back to at least the industrial revolution, if not before): a period when humans change the essential nature of the planet through their activities (primarily via the production of greenhouse gases).

But what comes after the Anthropocene? Some sort of Mad Max style wasteland perhaps?

Donna Haraway (2015) proposed that there will be a new epoch, the “Chthulucene” where refugees from environmental disaster (both human and non-human) will come together .
