Probing the submerged caves of Bermuda with Trident

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.”

Fun Science FRIEDay – The Emperor of all Maladies

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.

What the hell is the DC Metro’s “climate change will increase shark bites” ad talking about? An investigation

January 14, 2020January 14, 2020 David Shiffman

Blogging, Climate change

Ever since I moved to Washington, DC last summer, I’ve been fascinated by an ad campaign for the DC Metro. The premise of the campaign is simple: taking public transit reduces your carbon footprint compared with driving yourself. It highlights various negative consequences of climate change, and points out how riding the Metro can help fight them.

Many of these ads highlight well-known consequences of climate change:

Others highlight less well-known consequences of climate change, but are still on solid scientific ground:

But one ad in particular has been perplexing me for months:

We want to give you an ROV!

Open Science, Science

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 … Read More “We want to give you an ROV!” »

The next generation of low-cost, open-source oceanographic instruments is here! Meet the OpenCTD rev 2!

January 7, 2020January 7, 2020 Andrew Thaler 1 Comment

Oceanography for Everyone, Open Science, Science

Four generations of OpenCTD. Left to Right: Prototype 2, which went through sea trials in Lake Superior, rev 1, rev 1 in the smaller form factor (this one was deployed in Alaska), and OpenCTD rev 2.

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.

Shark Week 2019 reviews and thoughts

Popular Culture, Reviews and Interviews, Science

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:”

Rankings appear in no particular order, if you care about the order the shows actually aired in please see this Discovery press release.

10 sharks that mattered in the 2010’s

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.

Blogging

Every scientist I work with spends most of the day communicating, whether that’s preparing grants, manuscripts, theses, outreach talks, emails to colleagues/students… the list goes on. However, most of these outlets share fairly strict formatting rules. Grants comes with pages of guidelines. Talks have defined who I am, what I did, found, next, thank you slide. While this sterile approach is arguably fundamental to science’s critical tenant of replication, it makes for terrible communication.

Hello, world of Southern Fried Science.

The Field School team restrains a blacktip shark for a quick work-up during a female-scientist-led trip with the amazing non-profit Terranaut Club.

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.
