The Open CTD Project
Two weeks ago, we launched Oceanography for Everyone–The OpenCTD, a crowdfunding project to develop a low-cost, open-source CTD. After a few days hunting around for the best sealants, I put the prototype (name pending, suggestions welcome) through its first soak test. The results were… mixed. I left the CTD soaking for 12 hours (with hardware removed) … Read More “OpenCTD first soak test” »

The upcoming Joint Meeting of Ichthyologists and Herpetologists will include a research symposium focusing on the biology and conservation of durophagous (shell-eating) stingrays. Organized by Dr.’s Matt Ajemian (Texas A&M University Corpus Christi) and Julie Neer (Southeast Data Assessment and Review), this symposium aims to gather together the world’s experts on these ecologically important and poorly … Read More “#RaysTheRoof : Research symposium will focus on the biology and conservation of stingrays” »

The Open CTD Project
Last Friday we launched Oceanography for Everyone–The OpenCTD, a crowdfunding project to develop a low-cost, open-source CTD. This project won’t succeed without your help. To demonstrate how valuable a device like the OpenCTD is, for the next several weeks I’ll be presenting various projects that could be accomplished with access to low-cost CTD’s. First up … Read More “What can we do with an OpenCTD – high resolution hurricane monitoring” »
Science, The Open CTD Project
Head over to our Rockethub Page for more information! Conductivity, temperature, and depth (CTD). With these three measurements, marine scientists can unlock ocean patterns hidden beneath the waves. The ocean is not uniform, it its filled with swirling eddies, temperature boundaries, layers of high and low salinity, changing densities, and many other physical characteristics. To … Read More “Oceanography for Everyone – Help us build a CTD!” »
Science
Earlier this week, Fox News commentator and all-around terrific guy* Erick Erickson, while discussing a recent Pew Study that revealed that women were the sole breadwinners in 40% of US households that contain children, had this to say:
“I’m so used to liberals telling conservatives that they’re anti-science. But liberals who defend this and say it is not a bad thing are very anti-science. When you look at biology—when you look at the natural world—the roles of a male and a female in society and in other animals, the male typically is the dominant role. The female, it’s not antithesis, or it’s not competing, it’s a complementary role.”
I’m not sure where Erickson got his science education from, but it’s pretty clear he should have spent a little more time shopping around on the free market, because he sure is wrong. How wrong? I managed to assemble this list of 10 marine species with dwarf, parasitic, or otherwise reduced males (including an entire female-only class) while waiting for my toast**. So have a seat and let me show you how much weirder and more wonderful the world is than Erickson’s Disney-esque misinterpretation of biology.
1. Anglerfish
The deep-sea Anglerfish is among the most common examples of parasitic males in the marine world. Anglerfish comprise a variety of taxa in the order Lophiiformes. Almost all (females) possess a specialized appendage that acts as a lure to attract unwary prey. Life in the deep sea is rough–even though it is the largest and most diverse ecosystem on Earth, biomass is fairly low–so finding a mate is a struggle for these slow swimming fishes. The solution: carry your partner with you.
Male anglerfish are tiny, often less than 5% the size of the female, but they possess powerful olfactory receptors, allowing them to seek out females. Once a mate is located, the male anglerfish latches on to her abdomen, fuses his circulatory system with hers, and is then slowly digested until there’s nothing left but a sac of gonads surrounded by basic life-supporting tissues. Female anglerfish are not monogamous, either. At any given time she could be covered by a half-dozen parasitic males. Kinky.

This week, Animal Planet aired “Mermaids: The New Evidence” the second fake documentary in their series about mermaids. After complaining about the ridiculous show and the associated devastating effects on science literacy*, we decided to watch the re-air together and live-tweet it. The goal was to get real scientific information into the twitter conversation associated with the show. The Storify of our contributions to the discussion is below.
* Lots of people think that the admittedly fake documentary is real. Search the twitter hashtag #Mermaids and you’ll see literally hundreds of examples of this. These are not included in the Storify in the interest of not being cruel to strangers.

Tonight from 8-11 P.M. EST, Animal Planet is re-airing both fake mermaid documentaries, “Mermaids: The Body Found” and “Mermaids: the New Evidence”. We’re going to watch them. We’re going to live-tweet our thoughts using the show’s existing hashtag, #Mermaids. We’re going to systematically point out everything factually incorrect about mermaids (or anything having to do … Read More “Mock the Doc: Watch both fake Mermaids documentaries tonight and mock them on twitter with us!” »
Conservation
Earlier today, the Marine Conservation Institute and Mission Blue released SeaStates, the first ever national ranking of how well different U.S. states and territories protect their ocean resources. The full report is available online and is an important read, but can be summarized in 5 words: “Most states aren’t doing enough”.
The gold standard for the protection of marine resources is no-take marine reserves, areas of the ocean where no fishing or oil/gas extraction is permitted. Decades of research on marine reserves worldwide have shown that they usually have more fish, bigger fish, and more species of fish than environmentally similar areas (often adjacent to the reserve border) where fishing is allowed. In other words, when you don’t kill fish, more of them are alive.
