That ominous specter of death. The one certainty in life that we are all careening towards. But how much do we really understand about death? Medically death is defined as the moment the heart stops beating and cuts off blood to the brain. Within seconds after heart failure the brain’s cerebral cortex — the “thinking part” of the brain — slows down instantly and flatlines (meaning no brainwaves are visible on an electric monitor). This initiates a chain reaction of cellular processes that eventually results in the death of brain cells; as a result the brain’s functions also stop and can no longer keep the body alive. The big question is after the heart stops beating, and both heart and brain activity flatlines, how quickly does cognition or awareness fade? A relatively recent study suggests that consciousness continues even after death.
Alastair Harry is a fisheries science practitioner based in Perth, Australia. He assists in implementing ecosystem based fisheries management to support the sustainable use of wild-capture fish resources. He is a generalist and works across multiple areas including stock assessment, bycatch, and threatened species. He also holds an adjunct position at James Cook University and has a specific interest in the conservation and sustainable management of sharks and rays.
In August I published a review paper entitled Evidence for systemic age underestimation in shark and ray ageing studies. In it I suggest that many sharks and rays live considerably longer than is currently recognised. This increased life expectancy isn’t due to medical advancements or a more nutritious diet (or even better fisheries management), but rather the result of ageing error.

The OpenCTD and Oceanography for Everyone has been a five year journey from inception to first field-ready model and we’re just getting started. Building a community-driven project like this requires not just expertise (that we didn’t have when we started), passion, resources, it requires documentation. Extensive, detailed, thorough documentation. Documentation is what sets an open-science … Read More “Documentation is the beating heart of open-science hardware: Help make ours better!” »
We made a bot. It’s not a very good bot but it does prognosticate on novel ocean conservation solutions. @OceanCon_Bot has been running for almost a month and it’s produced some real gems. Solid, salt-of-the-earth, diamond-in-the-rough, gabbro-in-your-lab, bro, solutions. And these are among my favorites.
We definitely need to stop presenting those condescending academics, but why so down on transparency, @OceanCon_Bot?
Catalyze lionfish and address Caribbean extinction? I guess you can’t really do both.
Ok, it’s possible we created an evil ocean bot.

- The race to the bottom begins! Japan successfully undertakes large-scale deep-sea mineral extraction and Japan becomes the first nation to mine a deep-sea hydrothermal vent.

- Scientists spent a month terrifying guppies to prove that fish have personalities. Worth it just for the headline.
Sixteen hundred meters deep, off the coast of Okinawa, a new kind of mining just cut it’s teeth.
Earlier today, the Japan Times reported that a mining tool has successfully extracted zinc and other metals from a hydrothermal vent on the seafloor. There’s not much to go on yet. We don’t know if these were active or dormant vents (though dormant doesn’t mean biologically dead). We don’t know the specific location of the experimental mine site. And we don’t know the footprint of the ore prospect. But we do know that Japan has identified at least 6 potential mining sites within its exclusive economic zone and that plans are moving forward for a commercial mining venture in mid-2020. I’ve only found one report in English and from the look of things, there’s only a press release circulating right now, but I’m certain we’ll be hearing much more about this in the coming weeks.

We’re still watching to see what Nautilus Minerals does at Solwara 1 and how manganese nodule mining proposals in the Clarion Clipperton fracture zone are progressing but Japan’s mining efforts present a sea change in how to anticipate future deep-sea mining efforts. Private commercial ventures are dependent on the whims of the global commodities market and subject to national and international regulation. National efforts are driven by the need for resource independence. I was aware of Japan’s efforts, but didn’t realize that they were as close as they are to being ready for production.
For the last 10 years, we’ve been saying that deep-sea mining of hydrothermal vents is imminent. Well, it’s here.

It’s been over five years since Kersey Sturdivant and I launched Oceanography for Everyone – The OpenCTD, my first attempt at crowdfunding science. Over the years, that initial effort has grown into Oceanography for Everyone, a community of researchers, educators, and citizen scientists, and has created new open-source tools for open-source, open-science hardware. The OpenCTD is the finest oceanographic instrument that you can build in your own home for less than $300.
The crowdfunding campaign was a total disaster.
Since then, I’ve written several articles on how scientists can launch and managed crowdfunding campaigns:
- Can Crowdfunding Fill the Science Funding Gap?
- Setting Up Your Crowdfunding Campaign
- Managing a Successful Crowdfunding Campaign
…but I’ve never written explicitly about what we did wrong during that campaign and how it impacted our success. Now that the final reward from that campaign has been delivered (yes, five years later, talk about the eternally delayed crowdfunding campaign), it’s the right moment to look back and think about how everything went so wrong.
I went with lesser-known platforms. We launched the OpenCTD on RocketHub. At the time, RocketHub was hosting the #SciFund Challenge, a campaign to encourage scientists to launch science crowdfunding campaigns. Both the #SciFundChallenge and RocketHub were relatively small players in the nascent crowdfunding world. RocketHub doesn’t even appear to do crowdfunding anymore, they’ve pivoted to a “social network for entrepreneurs”. The old OpenCTD campaign page is long deprecated. #SciFund Challenge’s website hasn’t been updated in almost half a year.
Here’s the thing with crowdfunding, and especially crowdfunding in the early days: There are two dominant communities that you can rely on. There’s the community of people who want to support what you’re doing and there’s the community of people enamored with the idea of crowdfunding. Being a crowdfunding “investor” is a hobby in and of itself and many of the biggest donors are people who support dozens of different campaigns. So the larger and more popular the platform, the more crowdfunding enthusiasts you’ll attract. Heck, since backing the very first OpenROV, I’ve backed 23 other projects on Kickstarter, most recently Public Lab’s Balloon Mapping kits.
By going with RocketHub, I committed our campaign to a smaller potential audience. Considering Kickstarter was garnering huge press at the time, this was a near-fatal mistake.

Fog Horn (A Call to Action)
- The fight for our Marine National Monuments isn’t over. We now know of the contents of Zincke’s monument review memo, and it is not good. The DOI wants to see commercial fishing return to the Pacific Remote Islands and Rose Atoll Marine National Monuments. Longline fishing in these regions has historically been conducted by foreign fishing fleets which have been documented using slave labor. Many ecologists believe that maintaining these protected zones serve as a refuge that boost populations of many important commercial fish and improve the overall health of the fishery. Any change to monuments created under the Antiquities Act must be approved by congress. You’ve got a lot of reason to call you representatives this week, so why not add “I opposed the reintroduction of ecologically and economically destructive commercial fishing to the Pacific Remote Islands and Rose Atoll Marine National Monument.” to your script?

- Jellyfish sleep. Mind. Blown.
- Our Pacific Monuments are also extremely important scientific sites. Commercial fishing could jeopardize decades of research efforts in the remote Pacific. Scientists pan proposal to open pristine Pacific islands to fishing.
