Discovery of a Great Hammerhead Nursery

Happy Shark Week (if you celebrate), and I’m so excited to share our newly published open access paper about our research on juvenile great hammerheads (Sphyrna mokarran) with you! (It’s been hard to keep this one to ourselves).

Great hammerheads are an iconic shark species which have undergone significant population declines globally. In 2019, they were assessed as Critically Endangered by the IUCN Red List, which reported overfishing as the greatest threat to their survival. Great hammerheads are known to make incredible long-range migrations and cross state and international boundaries, making them challenging to protect as adults. Little is known about where they are born or where they spend their early years of their life, although there have been scattered reports of juveniles from the Gulf of Mexico, the Florida Keys, and one report from Georgia.

Identifying habitats that are important to juvenile sharks matters because young sharks are often the most vulnerable individuals in a population, and their survival is vital to the future of their species. Many juvenile sharks spend time in “nursery areas”—places where they are less likely to be eaten by predators, or where food resources are abundant. They then expand their ranges as they age, covering more distance as they grow larger. Identifying nurseries has long been a conservation priority for managers and scientists. After several years of research, our team has collected the first scientific evidence of a nursery area for great hammerhead sharks on the Atlantic coast of the United States—within sight of the skyline of Miami, Florida.

There’s a three-part established test for an area to be identified as a shark nursery: 1) Juvenile sharks are more commonly encountered in that habitat than elsewhere; 2) they remain in the area for extended periods; and 3) The area is used repeatedly over years. Our results demonstrate that this area definitely meets two of these criteria, with preliminary evidence that it also meets the third. We’ve found the same habitat may be a nursery area for several other shark species too, including scalloped hammerheads, another Critically Endangered species!

A decade of failures in Science Communication.

Eleven years is a long life for a science blog. Southern Fried Science was born in 2008, when the main writers were all graduate students. Over the last decade the online landscape has changed. Science Communication changed with it, adapting and evolving to meet an ever-shifting ecosystem. Looking back on the last decade and thinking about the next, it’s becoming easier to see where we went wrong. It’s not quite as easy to determine what we need to correct the course.

This is not a scientific assessment, this is my own personal observations from the last decade of running Southern Fried Science, from teaching Social Media for Environmental Communications for the last 7 years, from working with Upwell, one of the most dynamic and visionary ocean NGOs ever conceived, from helping build and launch multiple online platforms, dozens of novel programs, and hundreds of outreach campaigns, and from spending a lot of time since November 2016 reflecting on what we’ve done wrong.

That Hideous Deficit

Do we really need another 200 words on how bad the deficit model is and why it needs to die?

Apparently, yes.

The basic premise: that science perception and policy is shaped by an information deficit and that if we just make good science education content and spread it, we can combat the spread of misinformation, people will learn, and everything will get better.

It doesn’t work. It never worked. And it ignores the reality that misinformation is manufactured for political and financial gain, with tremendous incentives and, often, far better funding than science outreach campaigns. But beyond that, multiple studies have shown that, when confronted with information that challenges their fundamental world view, people don’t throw out their worldview, they reject the science, creating a more entrenched and intractable audience.

30 Earth Month Heroes

Earth Month Heroes Narrissa Spies, Edz Villagomez, Sylvia Earle, and Charlotte Vick.

Earth Day is April 22, which makes next month Earth Month.

I’d like to invite you to participate in a Twitter hashtag campaign for the entire month.  The purpose of this campaign is to bring some attention and praise to the people who are doing great conservation work.  I’m calling the campaign #30EarthMonthHeroes.

Participation is easy.  Starting on April 1, post a tweet about someone who you think is doing great work to protect the Earth or the Ocean, either someone you know or someone you would like to know. Say something nice, upload a photo, link to a story or a video, tag them, and use the hashtag #30EarthMonthHeroes. 

Each subsequent day, thread one additional tweet about someone you admire.  It’s important to thread your tweets, so that by the time you get to April 30, you will have one single long thread.  If you thread them properly, throughout the month, as readers find your tweets they will be able to easily scroll up and down to find the people that you’ve been tweeting about.  If this works the way I hope it will, even the people who find your tweets as late as April 30, will still be scrolling back to your tweets from April 1. 

If all goes according to plan, we reach new audiences on a large scale and greatly impact the conversation about conservation, while building a twitter following for ourselves, as well as the people who we call out as Earth Month Heroes. Plus it’s nice to hear from your colleagues when you are doing a good job.

It’s really that simple. 

This is meant to be voluntary and fun, and it’s a chance to say thanks to the people in our line of work who dedicate their lives to making the world a better place – so no pressure!

If you have any questions, please ask them in the comments section and I will try to answer them.

How do I thread my tweets?

Ask Twitter.

Does my Ocean Month Hero need to be on Twitter?

If you are picking 30 people that inspire you, chances are one or more are not going to be on Twitter.  Don’t let that stop you from recognizing them!  If you can’t tag them, you could try adding a link to their website or to something they wrote.

Does my Ocean Month Hero need to be alive today?

Again, you should recognize whoever you want.  I’ll be shocked if Rob Stewart and Ruth Gates don’t get a few mentions (I’m going to mention Rob, whose final film Sharkwater: Extinction comes out on Amazon Prime on April 22), and won’t be surprised if the likes of Henry David Thoreau or Rachel Carson pop up.

What if I need to miss a day?  Or a week?

That’s fine.  The idea is to post one Ocean Month Hero per day, but if you can’t post over the weekend, post three on Monday.  And if you only get to 14 over the course of the month, those 14 people will still be happy to be recognized by you.

Canada announced new marine protected area standards. Here’s how science and conservation professionals reacted.

Recently, the Canadian government released the Final Report of the National Advisory Panel on Marine Protected Area Standards. This report is a set of guidelines and goals for the creation of new marine protected areas in Canada, and comes as Canada is hoping to greatly increase the number and quality of MPAs. I reached out to MPA experts and environmental nonprofits to ask what they think.

Barndoor skates, once a textbook example of overfishing, have recovered enough to allow fishing

Barndoor skates were once thought to be so overfished that a highly-publicized paper from 1998 noted that they had been “driven to near extinction without anyone noticing.” One of the largest skates, barndoor skates can reach over 5 feet in wingspan, which is large enough that their diet includes small sharks like spiny dogfish; for a skate, that’s about as close as it gets to charismatic megafauna!

Recently, NOAA Fisheries announced that Barndoor skate populations off the Northeastern United States had finally recovered enough that fishing for them could resume. This move comes after a 2009 NOAA Fisheries report showed that the species had begun to recover enough that they could be removed from the species of concern list, though they remained protected at the time. “This is good news,” Mike Ruccio, a Supervisory Fishery Policy Analyst for NOAA Fisheries Greater Atlantic Regional Fisheries Office, told me. “Rebuilding overfished stocks is one of the cornerstones of the US domestic policy on fisheries.”

How many nuclear weapons are at the bottom of the sea. An (almost certainly incomplete) census of broken arrows over water.

What’s the weirdest think you’ve found in the ocean?

Several week ago, we tackled this question while discussing the incredible shrinking cups the deep-sea scientists like to decorate and send into the wine-dark deep. While toilets and spam cans and beer bottles make for good headlines and shocking images of how extensive human impacts are on the deep sea, those are far from the strangest objects to grace the sea floor.

By most reasonable metrics, that honor has to go to the many nuclear weapons and nuclear weapon components that have been lost at sea over the last 70 years. While a few high-profile incidents have received tremendous coverage, most incidents remain largely shrouded in secrecy, with only sparse reports available. Which brings us to a question that’s been lodged in my brain for the last month: just how many nuclear weapons are sitting at the bottom of the sea?

A Mark-43 nuclear bomb. One of these is at the bottom of the sea.

A Mark-43 nuclear bomb. One of these is at the bottom of the sea.

This, of course, does not include the many, many, many times the United States has intentionally tested nuclear weapons throughout the Pacific, often while forcibly relocating local communities away for their now-test-site homes or, occasionally, not. This also doesn’t include the rare lost nuclear submarine, who’s payloads and whether or not they carried nuclear ordinance are mostly still classified. And, of course, it doesn’t include the Soviets or any other non-US nuclear nation.

For the most part, the 1950s and 60s were a hell of a time for losing track of nuclear weapons. By the time the 70s rolled around we had decide that maybe we should be a bit more careful with these things. But by then, we had accidentally dropped at least ten nukes into the ocean in eight different incidents. And we had lost one in a Carolina swamp. And we had almost accidentally nuked Greenland.

Who the heck thought these things were a good idea?

In South Louisiana, Seafood Means Hope

This blog post and photo slideshow was created during OCEANDOTCOMM, an ocean science communication event, and supported by the Louisiana Universities Marine Consortium (LUMCON) The theme of OCEANDOTCOMM was Coastal Optimism. Photos were contributed by our lead photographer, Rafeed Hussain/Ocean Conservancy, with additions from other OCEANDOTCOMM attendees, including Melissa Miller, Samantha Oester, Susan Von Thun, Solomon David, Rebecca Helm, and Alexander Havens.

In many ways, South Louisiana is seafood- a trip here isn’t complete without eating some gumbo, oysters, or crawfish. Only one state (Alaska) lands more seafood than Louisiana’s 1.2 billion pounds a year (as of 2016). As of 2008, one in 70 jobs in the whole state is tied to fishing or related industries. According to the Louisiana Seafood Marketing and Promotion Board, “when you choose Louisiana seafood, you’re ensuring that your purchase benefits an American community and a way of life.”

When we visited Terrebonne Parish, home to nearly 20 percent of all commercial fishing license holders in Louisiana, we found that fishing means more to the people of this community than food and jobs. Here in South Louisiana, fishing is a vital part of the vibrant local culture and community pride. In a region that’s been devastated by hurricanes and oil spills, fishing is also a source of something more important: hope.

Below, you’ll hear what fishing means to South Louisiana’s fishing communities through the voices of a former shrimper, the owner of a grocery store that has served the town of Chauvin for more than a century, and representatives of a local Native American tribe. You’ll also get a glimpse into this beautiful part of the world through a photo slideshow. Together, this paints a picture of communities that have overcome unimaginable struggle, but still look forward to the future, in no small part because of the riches of the sea.

The most shocking, insightful ocean conservation solutions, as presented by a poorly-built Twitter bot.

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.

A new kind of robot to save the ocean!

It’s the Ocean Conservation Bot!

@OceanCon_Bot creates new an novel ocean conservation solutions by drawing from a vast and deep archive of randomly generate ocean jargon. @OceanCon_Bot is currently capable of generating 3.2 quadrillion potential ocean conservation solutions. @OceanCon_Bot is incapable of determining whether a solution is good, bad, gibberish, or really, really gibberish.

@OceanCon_Bot is parody, obviously. Mostly.


Hey Team Ocean! Southern Fried Science is entirely supported by contributions from our readers. Head over to Patreon to help keep our servers running an fund new and novel ocean outreach projects. Even a dollar or two a month will go a long way towards keeping our website online and producing the high-quality marine science and conservation content you love. And also let’s me dedicate a few hours to making weird twitter bots.
