Conservation, Technology, and the Future of the Seafloor: My 2023 science year in review.

Conservation, Technology, and the Future of the Seafloor: My 2023 science year in review.
Academic life, Science

2023 felt like a year where I was just treading water. I barreled through it so fast that I barely registered everything that we accomplishes (and just how much is left to finish). This was a kludge year for me, with lots of small projects instead of one, big, overarching project. Onwards! Deep-sea Mining remains … Read More “Conservation, Technology, and the Future of the Seafloor: My 2023 science year in review.” »

Community Oceanography with low-cost, open-source CTDs

Posted on September 23, 2022 By Andrew Thaler
Oceanography for Everyone

On September 14, 2022, I gave a talk on community oceanography and the OpenCTD for the AtlantOS Ocean Hour “Democratizing ocean observations through low-cost technologies” workshop. Below is the transcript from that talk.

Good morning and thank you for inviting me.

Access to the tools of science is not equitable, and nowhere is this inequality of access more pronounced than in the ocean sciences, where all but a few entities have the capital to mount major oceanographic research campaigns. I come from the world of deep-sea ecology, where budgets can quickly climb into the tens of millions of dollars. But even small-scale coastal research can be stymied by the need for vessels, equipment, and instruments, access to which is often controlled by research institutions.

As the need to understand the dramatic changes happening both at the surface and beneath the waves accelerates, barriers to access that precludes the participation of the full breadth of ocean stakeholders erodes our potential to understand, anticipate, and mitigate those changes.

One of the missions of my post-Academic career has been to make the tools of ocean science more accessible to more people. I believe that the ocean belongs to everyone and that the tools to study the ocean should be available to anyone with the curiosity and motivation to pursue that inquiry.

Chief among those tools is the workhorse of oceanography, the CTD.

Getting your kids started in conservation technology: a quick guide for parents who have no idea where to begin.

Getting your kids started in conservation technology: a quick guide for parents who have no idea where to begin.
Education

Southern Fried Science has been a bit dormant for the last year, so first, a re-introduction:

I’m Andrew Thaler, I’m an ocean scientist, and I make weird tech things.

Ten years ago I inherited an old mechanical tide gauge from a lab cleanout. For some bizarre reason, I thought: what if, instead of tracking the rising and falling tides in the Beaufort Inlet, it tracked the waxing and waning of conversations about sea level rise on Twitter. And thus, the Sea Leveler was born. 

Meet Sea Leveler: the open source water level gauge that wants you to talk about #sealevelrise

In a lot of ways, the Sea Leveler was the precursor of things to come. It was exhaustively documented and released as an open-source project on GitHub. It merged the digital with the physical, creating an object that allowed you to connect an online conversation to the real-world environment through repurposed technology. It was weird. And it was fun. 

The Sea Leveler itself was passed on to a good friend and champion of ocean outreach, but its legacy lives on in the plethora of projects to follow: Drown Your Town, Dolphin Vision, the reStepper, Turtle Borg, and, of course, the OpenCTD.

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

Posted on January 7, 2020January 7, 2020 By Andrew Thaler 1 Comment on The next generation of low-cost, open-source oceanographic instruments is here! Meet the OpenCTD rev 2!
Oceanography for Everyone, Open Science, Science
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. 

The very first OpenCTD prototype.

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.

Emerging technologies for exploration and independent monitoring of seafloor extraction in Areas Beyond National Jurisdiction

Posted on September 3, 2019September 3, 2019 By Andrew Thaler
Conservation, Exploration, Science

[The following is a transcript from a talk I gave at the 2019 Minerals, Materials, and Society Symposium at the University of Delaware in August, 2019. It has been lightly edited for clarity.]

Good afternoon and thank you all for coming. I want to change tracks for a bit and scan the horizon to think about what the future of exploration and monitoring in the high seas might look like because ocean and conservation technology is in the midst of an evolutionary shift in who has access to the tools necessary to observe the deep ocean.

This is the Area. Areas Beyond National Jurisdiction, International Waters, the High Seas, the Outlaw Ocean. It’s the portion of the ocean that falls outside of national EEZs and is held in trust by the UN under the Convention on the Law of the Sea as the Common Heritage of Humankind. It covers 64% of the ocean and nearly half of the total surface of the Earth. It’s also the region in which most major deep-sea mining ventures intend to operate.
