I’d like to introduce you to a new series I’ve been working on called “Conservation Conversations”. Each discussion, which will take place first on twitter, will focus on a particular marine conservation issue. I will then Storify and share selected responses here on the blog, allowing the conversation to continue. The first conservation conversation focused on sustainable seafood. A new paper showed that many fisheries scientists and conservationists believe that the Marine Stewardship Council’s “sustainable seafood” certification process is too lenient, a topic I’ve written about before. I wanted to know how my twitter followers decide what seafood is sustainable. I also asked whether they choose to avoid seafood entirely or focus on sustainable seafood. Continue reading Conservation Conversations: Sustainable Seafood We actually watched an Oceanic White-tip take several lunges at the ROV Isis on her way down. Sadly, she was only visible on the umbilical camera (a low-res upward facing camera we use to watch the status of the ROV’s tether), which we don’t record.  Where did that shark come from? The anemones around Beebe weren’t quite this colorful, but they were still fantastic.  A colorful anemone from the Beebe Vent Field.  One very accurate depiction of Rimicaris hybisae.
One of the great traditions among deep-sea scientists is the shrinking of polystyrene cups by sending them down to our research sites. Polystyrene (or Styrofoam) is mostly empty space. When sent to the bottom of the sea, the massive pressure (an additional atmosphere for every 10 meters depths) squeezes the air out of these empty spaces reducing the cups–or, in some more dramatic examples, mannequin heads and prop skulls a la Hamlet–to a fraction of their former size. With a little bit of creative doodling during down time, we end up with a nice illustration of this physical phenomenon that is undoubtedly an insufficient gift for our loved ones, of whom we’ve abandoned to spend 30+ days mucking about on a boat*. Fortunately, on my last expedition, I had the wherewithal to get before and after photographs of each cup the went over the side. So, for your enjoyment, for the next few weeks I’ll be posting some of my favorite shrunken cups. Enjoy!  Welcome to the Cayman Abyss! *Though, it could be worse. Rumor has it one group of researchers was so confident in their ability to deploy and recover remote deep-sea landers, that they all affixed their wedding rings to the deepest rig before sending it over. Fortunately, it returned, rings unscathed.
No, I don’t mean that there’s only one species of giant squid, Architeuthis dux, as was recently revealed by marine science rising star Inger Winkelmann, although it’s true. I mean that there is only one individual Archituethis dux, her name must naturally be Ducky, and, for the last 3 decades, she’s been messing with us. Let us review the evidence: Continue reading World’s only giant squid pulls off greatest prank in history
For each term, I’ve provided a definition from a scientific paper or technical report whenever possible. I have also provided some additional explanation in my own words, and some assistance from familiar memes. Whenever possible, I’ve linked to blog posts, articles, or websites that provide even more information. Most of these terms are broadly applicable to fisheries management policy, but some are specific to shark fisheries. It is not my intention with this post to strongly advocate for or against any specific policy (I do plenty of that with other posts), but to make sure everyone is speaking the same language. Continue reading 15 important shark conservation and management terms explained with memes

 The Sea Leveler, an open source, arduino-powered, water level gauge that measures activity on twitter. Two weeks ago, a machine was left on the “free” table at my lab that surprised me–a beautiful stainless steel mechanical water level gauge, on of those old ones with a flywheel in the back that drives the mechanism. Seeing this made me realize that there must be thousands of old scientific devices rusting away in laboratories across the country, obsolete but too well-build to just be thrown out. Then, I thought, there must be some way to take these old tools, some of them elegant, hand crafted works of industrial art, and give them a second life. For Science Online Oceans, I proposed a section on “Hacking the Ocean” developing low-cost, DIY instrumentation to make oceanography accessible to a broader community, but could that work the other way? Can we harness that same maker mentality to take abandoned scientific instrumentation and turn them into tools for education and outreach, or create art through instrumentation? So I built the Sea Leveler.
