We want to give you an ROV!

Posted on January 13, 2020 by Andrew David Thaler

Sofar Ocean Trident — *What will you explore?*

If you have access to a small, observation-class remotely operated vehicle to explore the ocean, where would you go? Would you use it to discover something new about marine ecosystems? Would you give students the opportunity to journey beneath the waves and learn about their local waterways? Would you hunt for lost lobster traps, track ocean plastic, deliver sensor payloads down into the mesophotic zone, or identify and protect critical spawning habitats?

Or would you undertake an expedition so novel that it has yet to be conceived?

Conservation X Labs in collaboration with Schmidt Marine Technologies and Sofar Ocean is delivering 20 Sofar Ocean Trident ROVs to researchers (both formal and informal), educators, citizen scientists, and ocean conservationist to help further projects to study, understand, or protect the marine environment, with a broad focus on marine conservation. Grant recipients will receive a Trident ROV with all the fixings!

Sofar Ocean Trident represents the next-generation of underwater drone. It is an out-of-the-box solution for ocean stakeholders that can perform many of the same functions of major research ROVs for a fraction of the cost and with no specialized training. Small enough to be stored in carry-on baggage, the ROV is extremely portable and has been deployed from vessels ranging in size from small kayaks to ocean-class research vessels to Polynesian voyaging canoes. Trident is fast, with simple controls. It is rated to 100m. The vehicle provides live video footage to the pilot through a kevlar-reinforced tether which can also serve as a recovery line. It has a series of ventral M3 mounting points that allow users to affix a variety of sensors, collectors, and payloads to expand its utility. It is one of the few consumer accessible vehicles capable of performing scientific research, documentary observation, conservation monitoring, and exploration from the surface of the ocean down into the mesophotic zone.

The application is simple and streamlined to get you out exploring the ocean.

Apply today and let’s discover the ocean together!

The next generation of low-cost, open-source oceanographic instruments is here! Meet the OpenCTD rev 2!

Posted on January 7, 2020 by Andrew David Thaler

Four generations of OpenCTD. Left to Right: Prototype 2, which went through sea trials in Lake Superior, rev 1, rev 1 in the smaller form factor (this one was deployed in Alaska), and OpenCTD rev 2.

In 2013, Kersey Sturdivant and I embarked upon a quixotic quest to create an open-source CTD — the core tool of all oceanographic research that measures the baseline parameters of salinity, temperature, and depth. We weren’t engineers; neither of us had any formal training in electronics or sensing. And, full confession, we weren’t (and still aren’t) even oceanographers! What we were were post-doc marine ecologists working with tight budgets who saw a desperate need among our peers and colleagues for low-cost alternatives to insurmountably expensive equipment. And we had ties to the growing Maker and DIY electronics movements: Kersey through his work developing Wormcam and me through my involvement with OpenROV.

We had no idea what we were getting ourselves into.

Seven years and five iterations later, we are releasing the long anticipated OpenCTD rev 2 as well as the comprehensive Construction and Operation Manual! OpenCTD rev 2 builds on over half a decade of iteration and testing, consultation with oceanographers, engineers, developers, and makers around the world, extensive coastal and sea trials, and a series of workshops designed to test and validate the assembly process.

Get into the spirit of Adventure: 10 Expeditions to follow in 2019

Posted on December 26, 2018 by Andrew David Thaler

The Aquarius Project: The First Student-Driven Underwater Meteorite Hunt

Pirates! Robots! Meteors! A team of plucky teenage explorers! If this doesn’t end up as a feature film, I’ll eat my red watch cap.

On Monday, February 6, 2017 a meteorite dropped out of space and dropped right into Lake Michigan. Since then, a team of young explorers sponsored by the Shedd Aquarium and the Adler Planetarium have been combing the lake for the lost meteorite. Catch up with this epic adventure through their podcast and on OpenExplorer. The search continues into 2019.

Iceland’s Shallow Hydrothermal Vents

Not all hydrothermal vents emerge in the deep sea. Of the coast of Iceland, shallow water vent spew forth their hydrothermal plumes in the shallows, where small underwater robots can easy access. You’d think we’d know more about them than their deep ocean counterparts but we actually know less.

Iceland’s Shallow Hydrothermal Vents hopes to fill in some of our understanding of these weird and wonderful ecosystems.

Search for Slave Shipwrecks

On a hot summer day in the murky waters of the man-made Millbrook Quarry in Northern Virginia, a group of about 25 people outfitted in scuba gear take turns going down to a depth of 30 feet, testing their compass reading skills, flooding their masks and practicing emergency ascents without air. The sight is not so unusual since Millbrook is the main training and certification site for scuba divers in the DC/Maryland/Virginia area and often hosts such groups. What might give folks pause, however, is that upon closer look they may notice that all 25 of the divers are African American. And if they chat with this unexpected bunch, they might also find that a majority are certified and qualified to search for, document and help excavate slave trade shipwrecks.
Search for Slave Shipwrecks

Divers with Purpose and the Slave Wrecks Project will be traveling across Africa and the Caribbean documenting the stories of underwater archaeologists working to preserve the history of the Atlantic slave trade buried at sea.

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

Posted on October 26, 2018 by Andrew David Thaler

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

Posted on September 20, 2018 by Andrew David Thaler

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.

Posted on July 24, 2018 by Andrew David Thaler

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

Posted on August 4, 2017 by Chris Parsons

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

Posted on July 14, 2017 by Amy Freitag

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

Posted on May 20, 2017 by Amy Freitag

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)

Posted on December 2, 2016 by Kersey Sturdivant

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!
