It’s the final cup in our series. Posting these images has been a fun way to reminisce about our adventures in the Cayman Abyss and hopefully give you a small glimpse into the more whimsical side of deep-sea research. To finish of the series, here is my favorite cup: That’ll do, pig, that’ll do.

It’s true! There are no giant tube worms (Riftia pachyptila) at the Mid-Cayman Spreading Center (but there are smaller tube worms). What all this about?

I am pleased to announce the return of Blue Pints, our Google+ hangout discussion series ! Join us at 6:30 P.M. EST on Monday 4/29! The Southern Fried Scientist will be discussing the Sea Leveler and other DIY projects related to ocean instrumentation, and I’ll be talking about ScienceOnline Oceans! We’ll share the link to … Read More “Blue Pints returns Monday 4/29 at 6:30 P.M.” »

I’ll be around Morehead City this year for the Big Rock Blue Marlin Tournament, finally with some post-dissertation time on my hands – and decided to finish a project looking at shifting baselines. Part of this investigation is to find out what people think about trends in the tournament since its creation in 1957 – fish size, difficulty in catching one, etc. It’s a small project involving a one-page survey but I decided that since ethics are important, I would run the survey through an institutional review board anyway.
Problem is, since I am post-dissertation and this is an independent project, I no longer fit into any of the categories of people who should be reviewed by my institution’s IRB: student, faculty, research staff, or administrator. I’ve heard this complaint from other community groups hoping to deploy surveys or get volunteers to evaluate their experiences in citizen science, but this is the first time I’ve experienced it firsthand. So if one does desire ethical oversight outside of an academic institution, where does one turn? I have a few thoughts, not of them tested, but I’d like to see the world of ethics expand beyond its institutional boundaries to match the expanding scientific boundaries of public science.

We visited some truly majestic hydrothermal vents. What’s all this about, anyway?
I have exciting news about ScienceOnline Oceans to share! General registration will start in a little over two weeks. As this is a little different from traditional scientific conferences, I’d like to explain the process in some detail.
Registration
Registration will take place in four stages.
1) Session moderators and workshop leaders. If your proposal for a session or workshop at ScienceOnline Oceans has been accepted (more information on that soon), a spot is automatically reserved for you, and registration will be a separate process. Please DO NOT register through the regular process.
2) Open registration. Open registration will take place on Wednesday, May 8th. To accommodate people in different time zones, there will be two registration times: 9:00 a.m. EST and 2:00 P.M. EST. There are 50 available spots during each timeslot, and they are first come, first served. In the past, ScienceOnline open registration spots have filled up in as little as 5 minutes, so please be sure to be prompt!
3) Lottery. The remaining spots will be filled by lottery. If you do not get a spot during open registration, sign up for the lottery and we’ll get back to you soon to let you know if you got a spot! Please note that the lottery is for the opportunity to register, not for a free spot.
4) Waitlist. There is also a waitlist for those who don’t get a spot during open registration or the lottery. As additional spots become available due to cancellations, people will be accepted off the waitlist.

There’s some seriously cool geology down at the world’s deepest known hydrothermal vents. What’s this all about?

We’re going into the Cayman Abyss! What’s this all about?
Popular Culture, Science
Evolution is the most creative force on the planet. Everywhere we look, we find species with novel and phenomenal adaptations that put their comic book brethren to shame. In no ecosystem is this more apparent than in the vast and unfathomable ocean. Marine species, especially those in the deep sea, have evolved to survive in a environment that is completely alien to us. Several months ago, I unveiled “Five organisms with real super powers that rival their comic book counterparts“, but that was just the beginning. Without further adieu, I give you 5 more marine organisms that put their superhero counterparts to shame (and one bonus critter).
The blind shrimp with super senses
In the deep sea, eyes are not among the most useful sense organs. While many deep-sea species have extremely reduced eyes, some have abandoned these organs entirely. Rimicaris exoculata is a shrimp endemic to deep-sea hydrothermal vents in the mid-Atlantic that is completely eyeless. Its carapace is smooth, without even a hint of reduced, vestigial eyes. This, unfortunately, is a problem because Rimicaris exoculata is a farmer. The blind shrimp grows bacteria in its gill chamber, bacteria that can convert the chemical-rich hydrothermal vent fluid into food for the shrimp.
For lack of a more descriptive adjective, hydrothermal vents are hot. Some can exceed 400°C. Rimicaris exoculata needs to get close to this hot vent fluid to feed its crop of bacteria, but not so close as to become a hydrothermal hors d’oeuvre. And so, the blind shrimp evolved a completely new light-sensitive organ mounted on the top of its carapace–the rhodopsin-rich dorsal eyespot.
The dorsal eyespot of Rimicaris exoculata doesn’t “see” in the normal sense, there is still almost no light in the deep sea. Rather, this shrimp is adapted to detect the black body radiation emitted by the hydrothermal vent. For Rimicaris exoculata, the deep sea glows with the light of super-heated hydrothermal fluid, allowing it to both find food for its bacterial crop and avoid getting cooked itself.
It should be no surprise that Rimicaris exoculata is undoubtedly the favorite deep sea organism of another blind champion with super senses–Daredevil.
