Everything Tangier is utterly fascinating right now: Angry messages to the Trump-supporting mayor of Tangier Island illustrate a need to listen, not to shout.
I’m still just dumbfounded by this: Did a Glowing Sea Creature Help Push the U.S. Into the Vietnam War? In other words, Ocean Literacy could save us all from annihilation.
I really hope you’re not sick of hagfish yet. Because Hagfish!

Best headline, ever: Sea Spiders Pump Blood With Their Guts, Not Their Hearts.

The EPA is seeking public input on the new administrations approach to environmental regulations. They are required to seek public input. They are required to respond to public input. Go tell them how you feel. Public comments close May 15. Here’s the docket with instructions on how to comment: Evaluation of Existing Regulations.

Titanic Tourism. Like this article: To Visit Titanic Firsthand, New York Banker Dives Deep Into Wallet. I have thoughts. Oh so many thoughts.

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!

Building robots in Papua New Guinea: update from #ROV2PNG

The view from our morning commute between Nusa and Nago.

Hello from the warm, sunny island of Nago, home of the National Fisheries College field station and staging ground for Marine Ecology via Remote Observation, part of the Marine Science Short Course. My team and I arrived in Port Morseby on Friday, where we met with Jamie on her way home and and caught up with my former student, now lecturer at UPNG, Freddie Alei, who joins us for the next week of class. Another day of travel brought us to the shores of Nusa Island. We had our first chance to meet the students on Sunday, during a walk around the local beach, followed by an afternoon flying Independent Lee, one of our demonstration robots, from the Fisheries’ jetty. It was a nice warm up for an intensive week of robotics and marine ecology.

There are two major components to the #ROV2PNG portion of the Marine Science Short Course. The first, and most visible, is the construction and operation of the OpenROV, an open-source underwater robot that is incredibly adaptable and expandable. Over the last three days, students have learned how to solder, weld acrylic, test electronics, use epoxy resins, and work together to assemble the chassis, endcaps, battery tubes, motors, and brain of the robot. Excitement is mounting as we approach the moment when we can power up the ROVs for the first time.

The next era of ocean exploration begins in Papua New Guinea

In 1946, Jacques Yves Cousteau and Émile Gagnan released the Aqualung, forever changing the way humans interact with the oceans. No longer tethered to the surface, entombed in thick, restrictive helmets, we could dive deeper, stay down longer, and explore the dark places snorkelers and free divers feared to fin. The Aqualung opened up the ocean to an entirely new cohort. Ocean exploration, once the domain of well-resourced scientists, career explorers, and the wealthy elite, was now within the reach of the global middle class.

Buoyed by the Aqualung, Marine Science exploded. Marine life could be studied alive and in situ. Behavior could be observed rather than inferred from the stressed and shredded samples of a trawl. The ranks of marine biologists, oceanographers, and explores swelled to numbers that began to gradually approach the relative significance of the ocean to the living world.

We’re just getting started.

Marine science is on the brink of the greatest sea change since JYC and Gagnan introduced the Aqualung to the world.

OpenROV is changing the way we think about ocean outreach and citizen science

Conservation

The SS Tahoe, once the only means of travel across Lake Tahoe, lies in 150 meters of icy, alpine water, scuttled after she outlived her usefulness. The remote lake presents an extreme technical challenge for divers and the wreck has spent her afterlife relatively undisturbed. Only a few dive teams have ever visited her.

Naturally, she makes the perfect target to test out the new, deeper-diving OpenROV.
