I made a ridiculous Glowing Wall Mount for my OpenROV Trident!

Because OpenROV Trident is a work of art and should be displayed as such when not on deployment. This was my first big design project using the Glowforge and integrating LED strips

If you have a Trident, you can download the plans and bill of materials right here: OpenROV Trident Glowing Wall Mount.

More importantly, if you don’t have a Trident, allow me to direct you to the SEE Initiative. OpenROV and National Geographic are giving away 1000 free Tridents to scientists, educators, and explorers. Apply today and let’s have an adventure together!

The rise of low-cost ROVs and community submersibles

The following appeared this Monday on the DSM Observer, the only trade journal committed to covering all aspects of the emerging deep-sea mining industry. Though written for the deep-sea mining community, the subject is broadly relevant to a host of ocean industries, so we reprint it below.

As a community, we discuss mining, management, and monitoring, as well as the regulations that shape them, in terms of governments, major corporations, and research institutions. The deep-sea mining community is small and the complexities of working at abyssal depths engenders collaboration, cooperation, and, in the case of exploitation, compromise. While there are many stakeholders potentially affected by deep-sea mining, only a small proportion of them will ever directly engage with the deep seafloor.

A few extremely wealthy individuals have access to private submersibles and ROVs and have on occasion made them available for research and exploration, but they are the exception. The tools necessary to reach the depths of a hydrothermal vent or polymetallic nodule field are simply too expensive.

That may soon change.

I built a head-mounted LiDAR array that lets you see the world like a dolphin via vibrations sent through your jaw.

I’m Andrew Thaler and I build weird things.

Last month, while traveling to Kuching for Make for the Planet Borneo, I had an idea for the next strange ocean education project: what if we could use bone-conducting headphones to “see” the world like a dolphin might through echolocation?

Bone-conducting headphones use speakers or tiny motors to send vibrations directly into the bone of you skull. This works surprisingly well for listening to music or amplifying voices without obstructing the ear. The first time you try it, it’s an odd experience. Though you hear the sound just fine, it doesn’t feel like it’s coming through your ears. Bone conduction has been used for a while now in hearing aids as well as military- and industrial-grade communications systems, but the tech has recently cropped up in sports headphones for people who want to listen to music and podcasts on a run without tuning out the rest of the world. Rather than anchoring to the skull, the sports headphones sit just in front of the ear, where your lower jaw meets your skull.

This is not entirely unlike how dolphins (and at least 65 species of toothed whales) detect sound.  Read More

Desert island discs – the marine conservation edition

In the UK, there is a famous and long-running radio show called Desert Island Discs. On this show celebrities are asked to imagine that they are marooned on a desert island, but they have rescued 10 discs (mp3s I suppose these days…) of songs that they have rescued from their sinking ship to keep them company on the desert island.

My chum – marine mammal scientist and general ocean hero – Asha De Vos recently asked for a list of key papers in marine conservation that she could pass onto students working on marine conservation issues in Sri Lanka. So I decided to write up my top ten “desert island” marine conservation papers that I think have been influential, and that all marine conservation students should read.

So after much pondering, this is my list:

Measuring the Cultural Value of Oysters

Most people from oyster-producing regions like the Chesapeake can attest to the fact that oysters are important the the social fabric of the community. In many towns that date back to the colonial era, oyster shells literally line Main Street and form the foundation of the town. In others, they form the basis of a modern-day bar scene boasting of “merroir” of the oysters alongside terroir of the wine. When the ecosystem around these kinds of places changes (think warming waters, acidified waters, introduced species who also love oysters), the resource underpinning this aspect of culture and heritage can be threatened. What does that mean for the humans so connected to the briny bivalve?

What Google Searches Tell Us About The Ocean… and Us

I recently discovered that Google Trends is a thing. Specifically, that they aggregate their search data and make it publicly available. Which is awesome. People Google much more honestly than they interact with others in person, more honestly than they answer surveys, and more honestly than they behave in a world where politics is important. So what people Google is insight into what people are curious about, where online outreach can have the most potential impact, and what is on the top of people’s brains at particular times. It tells us something about regionalisms, and seasonality of thought. I encourage everyone to play around with their data, for work or for play.

Here’s a couple of examples of things you can learn. Let’s start with the basics. Which states, over the last 12 months, have searched for “ocean” the most?

Fun Science FRIEDay – Water to Wine? Close, CO2 to Alcohol (ethanol)

Science brings us many wonderful things (honestly if you enjoy the benefits of the modern era, go out and hug a scientist). One of humanities age old desires is the ability to convert something invaluable, or a nuisance, into something desirable. The old midas touch if you will. Recently some scientist stumbled onto the process of converting CO2, a primary culprit of anthropogenic climate change, into alcohol… though not the kind you drink, the kind that humanity could use as fuel.

Producing fuel from CO2 is huge because it lets us take a nuisance compound, and converts it into a productive one. This was accomplished by scientists at Oak Ridge National Laboratory in Tennessee by using common materials (copper and carbon), but arranging them with nanotechnology. The researchers were attempting to find a series of chemical reactions that could turn CO2 into a useful fuel, such as ethanol. They figured they would go from CO2 to methanol, and then work out the logistics of going from methanol to ethanol, when they realized the first step in their process managed to do it all by itself. Science for the win!

Fun Science FRIEDay – Visualize the Seafloor

Happy FSF! As some of you may know (and for those who don’t), I study the bottom of the ocean, and I do so primarily using innovative technology to image the seafloor (e.g., Wormcam). The interesting work I’ve conducted has resulted in me having the opportunity to present my work to a larger lay audience, in the form of a TEDx presentation.

I am giving my TED talk with my good buddy and colleague Steve Sabo.  In our talk, “A Picture is Worth a Thousand Worms”, Steve & I will illustrate the significance of the ocean floor through advancements in underwater camera technology and data visualization, making complex science more accessible for everyone.

Ocean Outreach in an Evolving Online Ecosystem: Exploration wants to be shared

This is the transcript of the keynote I delivered at the Fourth International Marine Conservation Congress in St. John’s, Newfoundland. It has been lightly modified for flow.

Read Act II: Transforming the Narrative.

Now I want to shift gears and look towards the future, where we’re going, and what tools are available to help us get there. Because the future of ocean outreach, and really the future of ocean conservation, comes down to this one concept: “Exploration wants to be shared”.

The online ocean ecosystem is full of platforms–preexisting tools that allow us to produce, share, broadcast, enhance, and manage our outreach campaigns. Not just the obvious ones like Twitter and Facebook, but more niche tools like Slack, github, Ushahidi, medium, and yes, even PokemonGo, or if you want something a bit more serious, consider R as something that’s not just a statistics package, but a way to share your own software and data with the scientific community.

Fun Science FRIEDay – Open-Acess Science for the Masses

The oceans belong to all of us. With this simple statement in mind, the Oceanography for Everyone (OfE) project was launched with the goal of making ocean science more accessible. One of the biggest hurdles in conducting ocean science is instrumentation costs, and 4 years ago the OfE team began trying to make one of the most basic ocean science tools, the CTD (a water quality sensor that measures Conductivity-Temperature-Depth), cheaper… much, much cheaper!
