How do you get thousands of people interested in basic biological concepts? By teaching a course on some of the most fascinating animals on Earth – sharks and their relatives.
This is a particularly exciting time to be a shark scientist. An explosion of new research methods and technologies are leading to a surprising world of discovery. Our new course, free and open to anyone in the world, explores discoveries in many areas, including:

Six ways the new Old Spice ad violates the Marine Mammal Protection Act

February 15, 2016February 16, 2016 Andrew Thaler 9 Comments

Education

This is art. Maybe. Probably. Old Spice has taken it upon themselves to ask the all-important question: How many different violations of the Marine Mammal Protection act can we demonstrate in a single minute and fifteen second commercial? As it turns out, quite a few.

https://www.youtube.com/watch?v=5hteeecX1oQ

The Marine Mammal Protection Act expressly forbids the “taking” of marine mammals, a “take” being defined as:

“To harass, hunt, capture, collect, or kill, or attempt to harass, hunt, capture, collect, or kill any marine mammal. This includes, without limitation, any of the following:

the collection of dead animals, or parts thereof

the restraint or detention of a marine mammal, no matter how temporary

tagging a marine mammal

the negligent or intentional operation of an aircraft or vessel

the doing of any other negligent or intentional act which results in disturbing or molesting a marine mammal

feeding or attempting to feed a marine mammal in the wild.”

Broadly, this include any actions that may interfere with a marine mammal’s behavior or cause it undue stress. Fines can be… severe.

What is it about mercury? Thinking about chemicals in the public discourse

February 9, 2016February 9, 2016 Amy Freitag 1 Comment

Education, Science

All of the revelations about the lead in the water system of Flint, Michigan have made residents and curious neighbors alike wonder ‘haven’t we solved the lead problem’? There are thousands of well-established scientific studies; the sources and even many of the solutions are well-understood and frequently implemented. Not to say the problem’s gone, but we’ve wrapped are heads around it. So how is it possible that a new lead problem has surprisingly reared its ugly head? And more importantly, what does that mean for exposure to chemicals for which we’ve barely scratched the scientific surface?

The world of fisheries has its analog – mercury. We’ve all heard the recommendations for pregnant women and small children to avoid tilefish, swordfish, mackerel, and shark. We understand that it bioaccumulates in the food chain – and that as humans not exactly at the bottom, we’re susceptible. The dynamics of methylmercury (the poison variety) and elemental mercury are fairly well mapped out and we can identify areas of potential hazard where more methylmercury is likely to be naturally created. We’ve also stopped doing things like spraying mercury-based pesticides and covering our landscape and foodscape with the toxin. Kids have even stopped playing with ‘quicksilver’, it’s been removed from dental fillings and vaccines, and you should get rid of that mercury-based thermometer. Yet, if you scanned most people’s hair (the way we measure these things), there would be mercury present. And there’s still a host of ways they might have been exposed. But the better question is – if there’s still mercury in your body, what else is floating around in your system? And why do we focus on only the best-understood pathway of chemical exposure?

Scanning the Sea: How I create 3D printable ocean objects using a smartphone and free software.

November 7, 2015November 7, 2015 Andrew Thaler

Education

From simple sand dollars to life-sized hammerhead shark skulls, 3D printable ocean objects present an incredible opportunity for ocean outreach. Many commercial biological models are expensive, fragile, and often overkill for educators’ needs, where simple, robust, and easily replaceable anatomical models suffice. Over the last year, I’ve been honing my 3D printing skills, learning how to design 3D-printable objects, and mastering 3D scanning using free software and the now-ubiquitous smartphone. My designs, along with the open-source objects used for Oceanography for Everyone, can be found on my YouMagine profile (though Patreon supporters get early access to most prints).

Earlier this year, I wrote about how the ability to essentially photocopy a three dimensional object in a matter of hours revived my Ocean Optimism and opened up a whole new world of outreach possibilities. Since then, I’ve been working behind the scenes on some bigger projects that depend on 3D printing, one of which, Oceanography for Everyone launched last month. It’s a big ocean out there, and one person can’t possibly come close to producing a comprehensive collection of ocean objects. With several successful 3D scans under my belt, I think it’s time to share the process and invite the rest of the ocean-loving world join me in my efforts to scan the sea.

123D Catch, the software that powers it all.

Ocean Kickstarter of the Month: Meet Norman the Nurse Shark

October 6, 2015October 6, 2015 Andrew Thaler

Education, Science

In this book kids learn about sharks and the oceans as they travel with Norman on his adventure through the Bahamas.

Sharks4Kids First Book: Meet Norman the Nurse Shark

Sharks4Kids is an educational non-profit based in Florida that produces curricula and media designed to teach primary-school age kids about sharks and shark conservation. They also conduct Skype-in-lessons, classroom visits, field trips, and shark tagging camps. For their first Kickstarter campaign, they’re producing a book, targeted at elementary-school students.

Sharks matter, according to my co-author who uses the handle WhySharksMatter, and ocean outreach literature targeting younger students is often light on solid educational content. Online media is great, when available, but not everyone has reliable access to the internet. One of the campaign goals is to distribute this book to schools in the Bahamas, which is a major benefit to a region where persistent, high-bandwidth internet is not always a given.

Onward to the Ocean Kickstarter criteria!

1. Is it sound, reasonable, and informed by science? Sharks4Kids has a solid tract record producing entertaining and scientifically literate content that appeals to a younger audience. I have no doubt that Norman the Nurse Shark, though necessarily anthropomorphized, will provide fact-based, pseudoscience-free information about nurse sharks.

It’s been a big week for papers here at Southern Fried Science. This morning, Amy, myself, William (of Bomai Cruz fame), and Dominik and Erika of OpenROV published our guidelines on minimizing the potential for microROVs to act as invasive species vectors in Tropical Conservation Science. The abstract: Remotely operated vehicles (ROVs) present a potential risk … Read More “Keeping your robot invasions under control.” »

Ocean Kickstarter of the Month: The OpenROV Trident

The future of ocean exploration is here.

OpenROV Trident – An Underwater Drone for Everyone by OpenROV

I’ve been watching, exploring, and working with the folks at OpenROV since their last Kickstarter, way back in 2012. Today they announce the launch of Trident, the next generation underwater vehicle, and one of the most capable microROVs that I’ve ever seen. I had the rare pleasure to join them in Lake Tahoe this May to test fly one of the earliest prototypes, and it surpassed all of my expectations.

You don’t need to hear me sing the praises of one of the most important emergent technologies in marine science and conservation. The rise of affordable, capable, portable underwater robots will fundamentally change the way we think about exploring the ocean and monitoring ocean health.

Onward to the Ocean Kickstarter criteria!

1. Is it sound, reasonable, and informed by science? You bet. OpenROV have been building underwater vehicles for upwards of four years. I use their robots in my research and education programs. The first peer-reviewed publication using OpenROV as a research platform will be coming out at the end of the month.

How to NOT get ahead in advertising – what many conservation NGOs are doing wrong

August 17, 2015August 17, 2015 Chris Parsons

Conservation, Education

This year’s International Congress for Conservation Biology had a special double symposium on conservation marketing. What is conservation marketing I hear you ask? Well it’s using the tried and tested techniques from the advertising field, behind which there is a significant amount of research, to increase public awareness and especially change public behavior to aid conservation. Conservation marketing is already being used by several NGOs and initiatives – RARE for example. The Society for Conservation Biology has recently set up a working group for Conservation Marketing and Engagement* as it’s believed that this technique could help highlight many endangered species and highlight important conservation issues.

In this symposium myself and several colleagues had a presentation on why the advertising campaigns of conservation NGOs are doing things wrong – specifically these campaigns are often geared towards fundraising, telling members and especially donors what a great job they’re doing, launching surveys or petitions that do little to help conservation, oh and more fund- raising. The general public has a dire understanding of the need for biodiversity conservation or endangered species, and instead of increasing awareness and getting the public to change their behavior to act in a more pro-conservation manner, NGOs are instead concentrating on …hey did I mention fund-raising?!

As the result of many requests for copies of the presentation slides, I’ve decided to make them available for Southern Fried Science. Most of the slides are self explanatory. Feel free to copy and steal memes you like and count up the number of geeky references ….

A 3D-printable, drone and ROV-mountable, water sampler

August 10, 2015August 11, 2015 Andrew Thaler 2 Comments

Education, Open Science, Science

The Niskin bottle, a seemingly simple tube designed to take water samples at discrete depths, is one of the most important tools of oceanography. Coupled with a CTD, an array of Niskin bottles fit into the rosette, a Voltron-esque amalgamation of everything an oceanographer needs to profile the ocean. Niskin bottles are neither cheap nor particularly easy to use. A commercial rosette requires a decent-sized winch to launch and recover, which means you need a vessel and a crew to deploy. For Rogue Ecologist and citizen scientists, getting a high-quality, discrete water sample is a perpetual challenge. With tools like the OpenROV and the soon-to-be-completed EcoDrone, I wanted a Niskin bottle that was light weight and capable of being mounted on both underwater robots and quadcopters with ease.

Until now.

After a few months of brainstorming and planning, I sat down this Friday and began building a 3D printable Niskin bottle that could be hand deployed or mounted on an OpenROV or drone. While this version is designed around a 1.25 inch acrylic tube, the trigger mechanism can be expanded to fit any size pipe. The trigger is driven by a waterproof servo developed by the good folks over at OpenROV. Everything else can either be purchased off-the-shelf or printed on you home 3D printer. Later this month, I’ll be taking my prototypes out on the RV Blue Heron for field testing in Lake Superior.

Print your own Mighty Megalodon Tooth for #SharkWeek (or #JacquesWeek)

July 7, 2015 Andrew Thaler

Education

Carcharocles megalodon is the largest shark that ever lived. It roamed the oceans from 15 to 2.5 million years ago. Its teeth can be found at fossil beds around the world, but especially in Yorktown and Pungo River formations in the coastal Eastern United States. Megalodon teeth are incredibly useful teaching tools, allowing educators to convey just how massive these animals were and open up discussions about evolution, extinction, and ecology while instilling a sense of wonder.

Now you can print your own piece of prehistory with this 3D printable Megalodon tooth!
