Ten years ago, I launched a strange little project called Drown Your Town. The premise behind Drown Your Town was simple: I created a little macro in Google Maps that allowed you to superimpose a floodwater layer on top of 3D renders of communities. It was a quick and dirty way to demonstrate sea level rise in an era where those kinds of bespoke models were hard to generate. With #DrownYourTown, anyone, anywhere could simulate sea level rise in their own back yard.
It wasn’t originally going to be an outreach tool. I was writing a science fiction novel about life in a post-climate change world and needed an easy way to visualize places in the stories might look like. The book is still available, on Amazon, along with two other novellasthat I wrote, though I warn you, none of them are very good (in my defense, it was the high water mark for self-publishing ebooks and I was still trying to figuring out what my post-academic career would be).
One year ago today, my book “Why Sharks Matter: A Deep Dive with the World’s Most Misunderstood Predator” was released. Science moves (relatively) rapidly and changes often, with new discoveries every day, and the conservation landscape is similar. This means that it is impossible for anything written about these topics at a discrete moment in time to remain accurate forever.
So, in the interest of accountability, in the interest of continuing to make my book useful for public education about shark science and conservation even as the science and policy landscape changes, and in the interest of keeping notes for myself for any future updated versions of the book, I have been keeping track of things that I wrote at the time that are no longer true, or weren’t quite right at the time. (Please note that some of these facts and figures were already out of date at the time the book was pubished, but that was well after the final text was turned in).
Hi, it’s me, Andrew. And right now I’m crowdfunding an effort to develop an environmental baseline for microplastics in the deep sea using a historic sample archive. You can read more about it here: We need to know more about microplastics in the deep sea.
What is Experiment? Experiment is a crowdfunding platform that connects scientists with small-scale funders. It allows people to discover, fund, and disseminate scientific research and it is especially good at funding small pilot studies that are difficult to fund through traditional grant-making agencies but could lead to much more significant funding down the road. And right now, they have a campaign to fund ocean research.
Costa Rica lacks extended time series of oceanographic data. To address this issue, our goal is to deploy and maintain an array of smart mooring devices that will provide real-time data of temperature, waves and wind. We aim to describe how these variables associate to coastal erosion/coral bleaching in the Caribbean and coastal upwelling/ENSO coupling in the Pacific. Our mission is to provide open-access data to improve management of Marine Protected Areas and blue economy projects.
The deep sea is enriched with metals and amazing life forms. Electroactive microbes can get energy from metals, creating conditions that could sustain high animal diversity in the abyss. With genomic data to expand a large, public diversity dataset, we can use multi-omics and phylogenetics to reveal the electrobiogeochemical basis of biodiversity maintenance. It is urgent to know the role that metals play in such eco-evolutionary mechanisms before they are removed by the deep-sea mining rush.
Direct air capture (DAC) of CO2 is a technology for low-cost and scalable carbon dioxide removal (CDR). These systems will collect and concentrate CO2 from around 400ppm to approximately 20% CO2 by volume. The use of ocean based mineralization and enhanced weathering processes present a huge opportunity for gigaton sequestration of CO2. This project will explore low-cost sensors to quantify the mineralization and reaction rate of CO2 in a simulated ocean environment.
Trinidad and Tobago is home to many species of skates and rays but exactly how many and their locations are still unknown. There is a lack of knowledge on skate and ray biodiversity, life-history and ecology, however at least a third are thought to be on the IUCN Red List of Threatened Species. They are commonly caught as bycatch, and increasingly being kept for commercial sale. It is important to close these gaps in support of conservation and management.
“People think we are debating if this (deep sea mining) should happen or not, and that’s gone. It’s happening.”

One of the interesting things about deep-sea mining is that most of the people involved in the industry are environmentally motivated: the folks leading the charge for deep-sea mining and the folks urging caution have much more shared environmental values than coverage of the deep-sea mining negotiations would suggest. Which is why this quote caught me off-guard. Though an unapologetic proponent for the potential of deep-sea mining, Barron is usually much more diplomatic in his media statements. To declare that the debate is done seems reckless.
The deep-sea mining debate is most certainly not “gone”. It is, at the moment, more fiercely discussed that at any previous point in the industry’s 50 year history. While mining contractors have overcome significant political and technological hurdles to reach a point where they are on the cusp of the first commercial trials, the call for a moratorium on the development of the industry has more support, both within the International Seabed Authority, and without, than ever before. The invocation of the 2-year-trigger in 2021 jumpstarted the debate and forced the ISA to meet a deadline for finalization of the Mining Code, the legal structure that will determine when and how mining will proceed in the high seas.
Most of the plastic that enters our oceans in unaccounted for. While large, charismatic macroplastics float on or just beneath the surface, making for dramatic scenes of vast swaths of garbage littering the sea, the bulk of the plastic in the ocean exists as tiny particles of degraded plastics that sink to the bottom, enter food chains, and accumulate not just in the ecosystem, but within the tissue of marine animals.
If you’ve been following along with my adventures across social media, you may have seen that I recently inherited a massive collection of biological specimens from the deep sea. In addition to all the samples from my PhD work, I now have an archive that covers hydrothermal vents and methane seeps around the world collected over the last 20 years. This unique archive of biological samples provides a once-in-a-generation opportunity to establish a baseline for microplastic accumulation in hydrothermal vent and methane seep species.
My objective is to establish a baseline for microplastic accumulation in deep-sea macrofauna from hydrothermal vents and methane seeps. This baseline will allow us to address key questions about the accumulation of microplastics in the deep sea.
Do microplastics accumulate in species that derive their food from the chemical energy in the plume of a hydrothermal vent? Does microplastic accumulation differ among non-chemosynthetic species associated with vents and seeps? Do patterns of microplastic accumulation vary among distinct deep-sea ecosystems and the general abyssal plane?
Over the next few weeks, I’ll be sharing with you some of the weird and wonderful creatures that are part of this collection, including, of course, the iconic Giant Deep-sea Isopod (don’t worry, this particular specimen is staying on display).

Hey, Andrew, don’t you have a Patreon? Yes, yes I do. And I realize it’s super confusing to have two different fundraising platforms running simultaneously. Patreon supports this website, OpenCTD development, and my other weird projects. Experiment will be used to fund this microplastics study, exclusively. And, just to make things more confusing, everything I raise from Patreon this month will also go toward the Experiment microplastic project.
President Biden unveiled the nation’s first climate action plan specifically targeting ocean health. The Ocean Climate Action Plan advance several key climate initiatives, including providing 40% of federal investment benefits relating to climate change to disadvantaged communities; producing 30 gigawatts of energy from offshore wind by 2030; conserving at least 30% of U.S. lands and waters by 2030; and achieving zero emissions from international shipping no later than 2050. It’s a huge step forward and possibly one of the most consequential pieces of ocean policy since the Guano Islands Act.
Biden also announced plans to expand the Pacific Remote Islands Marine Monument, this would dramatically increase the proportion of protected oceans in US waters and get us closer to the 30 by 30 goal. The call also includes potentially renaming the Monument and several of the islands to recognize the history and heritage of Pacific islanders rather than the legacy of imperialism and colonization.
No word yet on the expansion of the Marianas Trench Marine National Monument.
This month, delegations from around the world agreed upon a treaty to protect biodiversity beyond national jurisdiction — ocean life beyond the limit of any country’s borders. The High Seas Treaty represents the culmination of over 2 decades of debate and negotiation. Once adopted, it establishes a framework for the protection and equitable sharing of marine genetic resources — animals and their DNA; promotes the implementation of marine protected areas in the high seas; and creates a scientific and technical body to review environmental impact assessments for ocean activities beyond borders.
Two years ago, I set out on a little mission: to build an off-grid solar array that would power my woodshop. This array needed to charge all my cordless batteries, but also drive my table saw, miter saw, circular saw, and the big router on my slab flattening jig. But there was a catch. The entire system could cost no more than one American Recovery Act stimulus check.
It worked. I beat the heck out of that set up and, other than in the dead of winter when it was too cold for the battery, it could handle most everything I threw at it, pretty well. It wasn’t perfect, and it had some issues with overdrawing, but the safety stops I put in place ensured that when I did push it too hard, it shut itself down rather than compromising components. There were limits, though, as I added bigger tools like a bench planer and started hogging through much tougher stock, I began to run into more and more issues.
So here we are, 2 years later, with all the upgrades and modifications that I made to my off-grid workshop to keep things running hard.
In the Last of Us, the most gruesome live-action adaptation of a video game about people being turned into fungus since 1993’s Super Mario Bros, a mutated species of Cordyceps destroys society by converting humans into mindless, sporulating mushroom people.
Cordyceps, a fungus that most commonly parasitizes ants, is real. It really does hijack its host’s nervous system, alter its behavior, and turn it into a spore-producing zombie. The outcome is strangely beautiful.
Though the current darling of gritty, realistic, science-based zombie fiction, Cordyceps is such a lightweight in the world of brain-breaking parasites that tech bros brew it into their adaptogenic coffee.
If you want to meet a truly unsettling zombie-making parasite, allow me to introduce you to Sacculina.
Sacculina is a genus of barnacle that parasitizes crabs. While most parasitic barnacles are perfectly happy growing on the carapace of a crab, Sacculina takes this partnership to the extreme.
Female Sacculina larvae drift through the ocean, until they encounter a crab. The larva then settles on the crab and searches for a joint in the crab’s carapace. Once it finds a gap in the arthropod’s armor, it transforms into a kentrogon, a specialized phase of the barnacle life cycle that possess a stylet–an organic syringe-like structure–which allows Sacculina to inject itself into the crab, and not much else. At this point, the hard shell attached to the crab’s carapace falls off and the barnacle continues to grown within its host.
Four years ago, I took over the Deep-sea Mining Observer from my predecessor, Arlo Hemphill. Conceived by the Pew Charitable Trust in 2016, The DSM Observer was created to be an online trade journal for the emerging industry as the International Seabed Authority navigated through the creation of an Exploitation Code for Seabed Minerals in the Area. Originally envisioned to run for two years, we continued to cover and report on critical developments into 2022.
After six years, the Deep-sea Mining Observer is coming to close.
