Conservation research in submarine caves is among the
clearest and most compelling use-cases for a small observation-class ROV like
Trident, which is why, last week, we delivered the very first ROV for Good
Sofar Ocean Trident to Dr. Leocadio Blanco-Bercial at the Bermuda Institute of
Ocean Sciences to study the hidden biodiversity in Bermuda’s Anchialine Caves.
Dr. Blanco-Bercial is a marine biologist who studies the
diversity and evolution in invertebrates, especially those in marine cave
ecosystems. Bermuda is home to a network of anchialine caves (caves connected
to the sea through underwater passageways) which are home to a diverse array of
rare and ancient arthropod lineages, many of which are unique to Bermuda. These
species are under threat from land development and other human activities.
“From the science standpoint,” says Dr. Blanco-Bercial, “the Trident will give us
independence from specialized divers availability, and will simplify the
logistics associated with the sampling process – the Trident is easy to carry
even by a single person – and sampling attachments and other gear is easily
transportable by another colleague.”
The Emperor of all Maladies is how Siddhartha Mukherjee, an Indian-born American physician and oncologist, aptly described cancer. Cancer, this scourge of mankind going back as far as 4,600 years ago when it was identified by the Egyptian physician Imhotep (the first in recorded history). Cancer takes one of the most successful traits of complex eukaryotes, cell division, and weaponizes it in unchecked cellular growth; some even consider cancer to be a more evolved form of cell division. This ailment has plagued humanity, and baffled physicians for centuries as they attempt to tackle the seemingly impossible, discover a cure for cancer.
If you have access to a small, observation-class remotely operated vehicle to explore the ocean, where would you go? Would you use it to discover something new about marine ecosystems? Would you give students the opportunity to journey beneath the waves and learn about their local waterways? Would you hunt for lost lobster traps, track ocean plastic, deliver sensor payloads down into the mesophotic zone, or identify and protect critical spawning habitats?
Or would you undertake an expedition so novel that it has yet to be conceived?
Conservation X Labs in collaboration with Schmidt Marine Technologies and Sofar Ocean is delivering 20 Sofar Ocean Trident ROVs to researchers (both formal and informal), educators, citizen scientists, and ocean conservationist to help further projects to study, understand, or protect the marine environment, with a broad focus on marine conservation. Grant recipients will receive a Trident ROV with all the fixings!
Sofar Ocean Trident represents the next-generation of underwater drone. It is an out-of-the-box solution for ocean stakeholders that can perform many of the same functions of major research ROVs for a fraction of the cost and with no specialized training. Small enough to be stored in carry-on baggage, the ROV is extremely portable and has been deployed from vessels ranging in size from small kayaks to ocean-class research vessels to Polynesian voyaging canoes. Trident is fast, with simple controls. It is rated to 100m. The vehicle provides live video footage to the pilot through a kevlar-reinforced tether which can also serve as a recovery line. It has a series of ventral M3 mounting points that allow users to affix a variety of sensors, collectors, and payloads to expand its utility. It is one of the few consumer accessible vehicles capable of performing scientific research, documentary observation, conservation monitoring, and exploration from the surface of the ocean down into the mesophotic zone.
The application is simple and streamlined to get you out exploring the ocean.
In 2013, Kersey Sturdivant and I embarked upon a quixotic quest to create an open-source CTD — the core tool of all oceanographic research that measures the baseline parameters of salinity, temperature, and depth. We weren’t engineers; neither of us had any formal training in electronics or sensing. And, full confession, we weren’t (and still aren’t) even oceanographers! What we were were post-doc marine ecologists working with tight budgets who saw a desperate need among our peers and colleagues for low-cost alternatives to insurmountably expensive equipment. And we had ties to the growing Maker and DIY electronics movements: Kersey through his work developing Wormcam and me through my involvement with OpenROV.
We had no idea what we were getting ourselves into.
Seven years and five iterations later, we are releasing the long anticipated OpenCTD rev 2 as well as the comprehensive Construction and Operation Manual! OpenCTD rev 2 builds on over half a decade of iteration and testing, consultation with oceanographers, engineers, developers, and makers around the world, extensive coastal and sea trials, and a series of workshops designed to test and validate the assembly process.
I wasn’t able to watch live this year, but I DVR-ed all 18 specials and watched them eventually! Here are my reviews, ratings, and thoughts. I did not watch the feature-length movie, which they claim is the first fictional entertainment content they’ve ever produced… causing me to stare in megalodon. Overall, this was not a strong year for science, facts, or diversity (of either sharks or shark researchers).
As a reminder, I grade on the following aspects of a show: is there actual science or natural history educational content / is there made up nonsense, are actual credentialed experts with relevant expertise featured or are they self-proclaimed “shark experts” who say wrong nonsense all the time, what species are featured (with bonus points for species we rarely or never see), and do they feature diverse experts or just the same white men (reminder: my field is more than 50% women)? It’s not a perfect rubric, but it’s better than this actual system for ranking shark news introduced this year in “sharks gone wild 2:”
Just when you thought it was safe to read another decade-in-review listicle…
As the 2010’s come to an end, it’s a time to reflect on the often-problematic decade that was as we plan for a hopeful future. I am a sucker for year-in-review and decade-in-review listicles, and was devastated to learn that no one had yet written a decade-in-review listicle for sharks! Please enjoy my official, scientific list of the most important science, conservation, and pop culture sharks from the past decade.
I’m Catherine—if we’re being official about it, Dr.
Catherine Macdonald—and I’m the newest contributing writer around here. Before
we get into science, I thought it might be helpful to get better acquainted.
[The following is a transcript from a talk I gave at the 2019 Minerals, Materials, and Society Symposium at the University of Delaware in August, 2019. It has been lightly edited for clarity.]
Good afternoon and thank you all for
coming. I want to change tracks for a bit and scan the horizon to think about
what the future of exploration and monitoring in the high seas might look like
because ocean and conservation technology is in the midst of an evolutionary
shift in who has access to the tools necessary to observe the deep ocean.
This is the Area. Areas Beyond National
Jurisdiction, International Waters, the High Seas, the Outlaw Ocean. It’s the
portion of the ocean that falls outside of national EEZs and is held in trust
by the UN under the Convention on the Law of the Sea as the Common Heritage of
Humankind. It covers 64% of the ocean and nearly half of the total surface of
the Earth. It’s also the region in which most major deep-sea mining ventures
intend to operate.
Today, there are more robots exploring the ocean than ever before. From autonomous ocean-crossing gliders to massive industrial remotely operated vehicles to new tools for science and exploration that open new windows into the abyss, underwater robots are giving people a change to experience the ocean like never before. The fastest growing sector of this new robotic frontier? Small, recreational, observation class ROVs.
Reprinted below are the explicit guidelines proposed in the paper.
1. Education. Central to any mitigation strategy involving diverse stakeholders, ranging from professional to recreational, is user education. The following are critical to establishing a responsible user community: Ensuring all potential microROV users 1) not only understand the laws and regulations for wildlife viewing that apply to the jurisdiction in which they are operating, but understand why those regulations are in place; and, most importantly, 2) have internalized a stewardship ethic that motivates them to respect the rationale behind those regulations even when operating in regions where those regulations are not enforced. This is most effective when it occurs at point-of-sale or registration of the microROV. Thus, while the additional four guidelines relate to the user, this first one relates to the manufacturer. To most effectively convey the potential harm that microROVs could pose to marine mammals, the manufacturers are best positioned to educate their user base by providing informational material with each microROV sale.
