Occupation Cinematographer, producer, aerial pilot

Diver Since 1969

PADI and HSA Instructor 20-plus years

Started in TV Production 1978

We protect what we love; through the Census of Marine Life, this cinematographer showed us 2,000 new reasons to care

Rick Morris has been invested in the ocean as long as he can remember. But the highlight was his three years as the cinematographer for the Census of Marine Life, which eventually documented more than 5,000 new species overall.

Tell us about the Census of Marine Life.

Working with 2,700 researchers from 80 different countries on a 10-year project to assess the diversity, distribution and abundance of all the creatures in the world’s oceans was mind-boggling. How can we regulate and preserve our oceans if we don’t know what’s in them? There has to be a baseline. During my tenure on the project nearly 2,000 new species were discovered, and more than 5,000 during the 10 years.

What was your biggest challenge?

Five weeks filming in the Arctic, where you pull all your gear across the frozen ocean on a sled with a rope around your waist, about 500 pounds of gear. When you get to the dive site, ¾ of a mile away, you hand-cut your entry triangle, and in two-person teams tethered together, you dive and collect specimens under the ice for up to 45 minutes in 28 degree water. Having conquered the Arctic, I know I can handle any challenge in life.

What are you working on now?

Sustainability has been the key and my focus. I am currently working on a project on goliath grouper aggregations off the coast of Florida, and a film on an amazing couple from New Jersey who started a shark conservation and diving operation in the Caribbean.

How can everyday divers help further your work?

Attend shows and festivals where our films are shown and watch our work on line. Contributions to nonprofits can really make the difference in the final product we create. No one has put it better than 2012 Sea Hero of the Year Jill Heinerth: “We are water.” Without healthy aquatic environments, the human species will perish. If we band together now we can affect change. My job is to make it real for everyone.

Each Sea Hero receives an Oris Aquis Date watch valued at $1,595. At the end of the year, a panel of judges selects a Sea Hero of the Year, who receives a $5,000 cash award from Oris to further his or her work. Go to scubadiving.com/seaheroes to nominate a Sea Hero today.

Champion freediver Estrella Navarro.

The first annual “Big Blue” international freediving competition is scheduled for November 1-9, 2015.

Event organizer and Mexican national record holder, Estrella Navarro (in cooperation with AIDA Mexico and Cressi), is offering the competition to give athletes from around the world the opportunity to test their freediving limits in the beautiful, deep waters off Isla Espíritu Santo, Baja, Mexico.

“The Big Blue will feature five days of competition, one day of swimming with whale sharks, and a conference to promote ocean conservation,” says Navarro. “The visibility in November is the best of the year — you can see up to 30 meters [98 feet]! Plus we are giving each athlete the flexibility of choosing between constant weight (CWT), constant no-fins, and free immersion (FIM) for every dive — the choice is theirs!“

Inaugural attendees will include Guillaume Néry, Alexey Molchanov, and Carlos Coste.

Navarro recently broke three freediving records for her country of Mexico in one breath during this year’s Caribbean Cup in Roatan, Honduras, on June 2, 2015.

November/December 2015 Sea Hero: Kurt Lieber

KURT LIEBER

Ocean Defenders Alliance Founder Kurt Lieber

Patrick Strattner

Occupation Founder/executive director, Ocean Defenders Alliance

Diver Since Mid-1970s

Helped Establish California’s MPA network, which protects 16 percent of state waters, nearly 10 percent in no-take zones

Founded in 2000 amongst friends, Ocean Defenders Alliance now connects hundreds of divers and “deck volunteers” in its mission to protect California’s ocean treasures, especially from the deadly effects of ghost nets, equipment lost or abandoned by fishermen. For his efforts, founder and executive director Kurt Lieber is our November/December Sea Hero.

You have been involved in a lot of projects with Ocean Defenders Alliance — which has been the most meaningful to you, and why?

I started this organization in the year 2000, with some friends. Through the years, Ocean Defenders Alliance (ODA) has turned into a dynamic union, and we’ve had over 200 divers and hundreds more deck volunteers go out with us on various projects. In 2013, I contacted the people at the Channel Islands National Marine Sanctuary (CINMS) to see if they would allow us to go into the sanctuaries and start removing ghost gear there. This area is a national marine sanctuary, national park and marine-protected area. As such, its biological importance — and sensitivity — is without question. After a lengthy qualification process, we were given a scientific collecting permit. We are the only all-volunteer group with this permit that I know of. That means a lot to me.

What is the biggest challenge you have faced in your fight against ghost nets and marine debris in general?

When I first started ODA, I couldn’t find anyone who knew about the damage that was being done by ghost gear. The Internet still wasn’t a tool widely used to gather or share information. So, I had a difficult time convincing the general public that this was a serious issue; marine debris is a good but dismaying example of the old saying “out of sight, out of mind” as far as public consciousness goes. Fast forward 15 years, and the tide is changing. There is now a great source of scientific information available that informs people with a lot of statistics. One that absolutely makes me cringe is that NOAA estimates that 330,000 whales, dolphins, seals, sea lions and turtles die in ghost gear every year. The problem is that every year, the commercial fishing industry loses a staggering amount of gear (i.e., lines, nets, and traps). Consequently, our work is never done.

What’s been your most satisfying moment?

The vast majority of nets we locate and remove are made out of synthetic material, like nylon or mono-filament line. Scientists have estimated that nylon nets will last 650 years in the oceans. A net that is in the water for that long does no one any good. Animals are dying continuously, needlessly, and divers are losing what we all want to see alive, FISH! The fishing community loses as well because of decreased populations. To date we have removed approximately 21,000 pounds of these deadly nets. One of my most satisfying moments was pulling together a fantastic group of volunteers, and together we removed about 1,000 pounds of gill net from just one location. That does not sound like a lot, but think about that for a moment. What would a 1,000-pound pile of fishing line look like? Well, that is what some of these deadly derelict nets are made out of; it can be a huge, and hugely harmful, collection!

Tell us a little bit about what you are working on now?

It is a really exciting time for us right now. Not only are we continuing to clean more of California’s coastal waters, such as in the CINMS, we are also in the midst of establishing a new base in ODA in Hawai’i. As awareness expands through the dive community, we are getting a lot of interest from different areas of the U.S. that are inquiring about creating ODA bases all over the country — and we know that ALL coastal waters need the kind of service we provide. The Seattle/Portland area is looking promising for a future base as well.

How can divers and Scuba Diving‘s readers help further your work?

As anyone who has ever owned or been around a boat knows: Things are always needing maintenance, repair or replacement! We have the manpower and know-how, but we are constantly working to keep our boats running well and fueled up. So, to keep us at sea doing what we do best, donations are very welcomed. Another option is to start a removal project in areas where your readers come across debris. And I don’t mean only ghost gear. Plastics are a huge plague that we have got to address if we want to future generations to enjoy the wide variety of life forms that the oceans historically have supported. Want to know what the oceans looked like before the invention of the steam engine? Read The Unnatural History of the Sea by Callum Roberts for a good dose of reality. In other words: Get educated and get involved! If this problem is going to be solved, we are the ones who are going to have to make it happen.

What’s next for you and Ocean Defenders?

We purchased a new (used) boat late last year, and we’ve been working on upgrades and repairs ever since. It is currently berthed in San Pedro, California. As soon as we are finished with this phase, we’ll be moving the boat up to the Channels Islands Harbor, and resume our removal projects in the Channel Islands.

What would you do with the $5,000 Oris award if selected for Sea Hero of the Year?

If I am selected for this honor, I will put the money directly into our boat in order to launch additional debris-removal expeditions. I have recently received reports of several marine debris sites throughout Southern California that urgently need our removal expertise. This award would allow us to travel further from our home port and get to sites we haven’t been able to reach because of the high costs of fuel, oil and boat maintenance.

Is there anything we did not ask that you would like readers to know about? Tell us what’s important to you!

I’ve been diving since the mid ’70 s, and have seen a drastic decline in biodiversity, water quality and wildlife sightings and interactions. Having witnessed this loss first hand is what drives me to do what I can, in my lifetime, to defend ocean life and habitats. Over the last 15 years or so, I have seen what marine-protected areas (MPAs) can do to help marine species bounce back. I was heavily involved in the state of California’s decision to create MPAs up and down our coast. While the scientists recommended that 30 percent of our waters be set aside as no-fishing zones, when all was said and done, we ended up with 16 percent of our state waters having some kind of protection, and only 9.4 percent of that is no-take. A far cry from what the science dictated for species’ survival. But it is a start. I would love to see our no-take areas expanded, not just in California but throughout the world. The effort we are putting into aquaculture as a “work around” for our diminished fish populations is like putting Band-Aids on a cancer patient. We must attack the root cause, which in this case is the threat to wildlife species and habitats caused by overfishing. Nature has proven time after time that she can heal herself if we leave her alone. MPAs are one of the few real remedies for our dying oceans.

Lastly, I want to leave readers with hope. Each of you reading this can make a difference; you must simply choose to become involved. You can educate yourself and others. You already possess the power to influence things for the better through your votes, your buying decisions, what you eat and where you invest your time and resources. All you have to do is join our alliance and be an Ocean Defender!

Seahorse Tail is Inspiration for Robotic Arm

What does a seahorse tail have to do with the original “flying machine,” Velcro and surfboards that are more maneuverable? The inventors of all three — Orville and Wilbur Wright, George de Mestral and Frank Fish, respectively — were inspired by nature (see Bioinspiration at the bottom).They were practicing biomimicry,a field of science that looks for innovative solutions to human problems by emulating nature.

In 2013, researchers at the Jacobs School of Engineering at UC San Diego were looking for something in nature that was flexible and resilient, in the hope that it could lead to better-designed robotic arms. The challenge for engineers: how to make a robot safe when working around “soft” humans, such as when a bot assists a physician during surgery or hands off a tool to a factory worker.

The researchers zeroed in on seahorses and their square, segmented tails.

“The tail is the seahorse’s lifeline” because it allows the animal to anchor itself to corals or seaweed and hide from predators, said Michael Porter, at the time a Ph.D. student at UC San Diego and now an assistant professor at Clemson University. “But no one has looked at the seahorse’s tail as a source of armor.”

The seahorse’s tail protects it from its main predators — wading birds, crabs and turtles, which all are capable of delivering crushing bites — by enabling the seahorse to lock onto plants such as seaweed. Porter knew its square plates make the seahorse’s tail stiffer, stronger and more resistant to strain — all at the same time. Usually, says Porter, strengthening any one of these characteristics will weaken at least one of the others.

After moving to Clemson, Porter assembled a team to take the question a step further. Researchers used a 3-D printer to build models of the seahorse’s tail and a set of rounded plates to see which worked better. Then they tried to destroy them. They bent, twisted, compressed and crushed the 3-D versions (see the illustrations above).

“New technologies like 3-D printing allow us to mimic biological designs but also build hypothetical models of designs not found in nature,” says Porter. “We can then test them against each other to find inspiration for new applications.”

Porter says engineers could design a similar structure to make flexible robotic arms, which could be used in medical devices, underwater exploration, and unmanned bomb detection and detonation.

Detailed findings were published in the journal Science in July.

BIOINSPIRATION: SCIENCE IMITATING NATURE

Brandi Mueller

Bioinspiration, the practice of science imitating nature, is leading us into the future — one tail at a time.

Studying pigeons in flight wobbling from side to side helped the Wright Brothers solve the “flying problem” — how to control an aircraft and enable sustained flight.

If your BC employs a Velcro cummerbund, you have George de Mestral to thank. After a hunting trip in 1941, the Swiss engineer’s dog and clothing were covered in burs. Using a microscope, Mestral saw multiple hooks on the burs that attached to fur and socks. After experimenting, Mestral invented the hook-and-loop Velcro fastener.

And the better-performing surfboard? Frank Fish, a biology professor in Pennsylvania, wondered about the warty ridges called tubercles on humpback whale fins. Fish found that the bumps have a purpose: They reduce drag and noise, increase speed and boost power; today, they’re found on Fluid Earth surfboards.

Children's Book: Sea Turtle Rescue

Eric Douglas

Check out the latest book by Eric Douglas!

Sea Turtle Rescue and Other Stories now available!

Eric Douglas — author of Scuba Diving‘s Lessons for Life columns and a number of books — has just released a collection of chapter stories for young readers from kindergarten to third grade. Sea Turtle Rescue and Other Stories includes four full-length chapter books in a single package. The stories follow Jayne and Marie, along with their friend Monique and Javier around their home on the Outer Banks of North Carolina as they learn about the ocean, history, science, sea turtles and sharks.

“When my girls were young, after reading innumerable Magic Treehouse books with them, I decided to write them their very own chapter books to read. The first story was Sea Turtle Rescue and sea turtles still hold a special place for us today. Over the years, I wrote three more stories,” Douglas said.

Three stories in the collection were published as part of the Newspapers in Education program, making them available in serial form for kids from all over the country to learn about the ocean. They were published in places as far apart as Bermuda and Iowa.

“These stories are great for kids (or grandkids) interested in the ocean. The two main characters are young girls, but boys like the stories as well. My step-nephews tell me how much they like the stories all the time.”

Sea Turtle Rescue and Other Stories is available in softcover for $10 and in ebook format for $5.99. The ebook is available through Kindle, Nook and most other ebook retailers.

You can find out more, or read reviews from Sea Turtle Rescue and Swimming with Sharks on his website at www.booksbyeric.com.

Description
Two young girls move to the Outer Banks of North Carolina and learn about the ocean and life on the coast. There are four early chapter books in this collection, written for readers six- to nine-years-old. The stories are exciting but also include information on science, the ocean and history.

Sea Turtle Rescue is an ocean story about protecting sea turtles. When an injured sea turtle shows up near their home on the Outer Banks of North Carolina, Jayne and Marie, along with their friends Javier and Monique, search the beach to find the turtle’s nest and protect it from danger. They know the time is getting short and if they don’t find it soon, the eggs might not get a chance to hatch.

Fight for Fort Hatteras is a history story about the civil war. Jayne and Marie take a school trip to visit the site of a Civil War battle near their home on the Outer Banks. Marie wanders off and finds herself in the middle of the battle and afraid she may never see her family again.

Hurricane! is a science story on hurricanes hitting the coast. Jayne and Marie are faced with Hurricane Erin bearing down on their seaside town. Do they evacuate or stay with their father and protect the aquarium?

Swimming with Sharks is an ocean story about sharks and their value. Jayne and Marie love the ocean and enjoy spending time out on the water with their parents. For them, sharks are beautiful creatures, not something to be feared. But an up close and personal encounter makes Marie think twice.
