ScienceOnline Oceans update: Registration information and costs

Posted on By David Shiffman

sciooceansI 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.

Five more marine organisms that put their superhero counterparts to shame

Posted on By Andrew Thaler
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

Rimicaris exoculata – http://eol.org/data_objects/13231836

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.

Arduino Project Log: Building the Sea Leveler Part 1 – Hardware

The Open CTD Project

The Sea Leveler.
The Sea Leveler.

Two weeks ago, I announced my latest Hacking the Ocean project, an open-source, Arduino-powered water level meter that monitors the frequency of tweets containing the hashtag #sealevelrise. Since launch, the Sea Leveler has had some bugs and received some good press.  Now that I’ve had some time to monitor its performance and work the bugs out of its code, it is finally time for the promised “how to build the Sea Leveler” post.

This project was much more involved than my Arduino build and significantly more rewarding. The Sea Leveler was a challenge on multiple fronts, from learning to make the Arduino talk to twitter to physically modifying the water level meter. As I noted in my first project log, I have very little programming experience, and the major goal of this build was to level up my C++ skills. I’m very happy with the results, both technical and aesthetic.

For simplicity, I’m going to break this into two posts, one for hardware and one for software.

Conservation Conversations: Sustainable Seafood

Posted on By David Shiffman

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.

Surviving Grad School: Credit Cards, Reimbursement, and International Travel

Posted on By Andrew Thaler

headshot-thalerSMALLReimbursements and International Travel

Graduate school comes with several financial challenges that require planning and careful attention to details. Chief among these challenges are the two big wallet busters: university reimbursements and international travel. Often these two combine to form a deadly, money sucking hydra. You will inevitably need to pay for something – airline tickets, hotels, fuel, equipment, contractors – out of your personal funds, and then file for reimbursement with your university. Depending on how efficient your finance office is, it could take anywhere from four days to several months for your reimbursement to be issued. If you paid with a credit card, during this time you’re paying interest on those charges.

International travel adds another layer to the mix.  Most credit card companies will charge a foreign transaction fee (often 3%), there’s a high degree of variability regarding which networks are accepted where, and many nations have adopted EMV chips (a feature few US cards have) for added security. Whether it’s for a field season or a major scientific conference, you will probably have to make at least one big international trip. If you haven’t planned ahead, you may find yourself stuck with little or no functional currency, and end up leaning heavily on cash advances, travelers checks, or other high fee alternatives.

You should use a credit card to pay for reimbursable expenses, especially travel, if for no other reason than you need money in your bank account for things like food and shelter. If you’ve read my previous post–Credit, why it matters, how to build it, and how to use it–then this should seem familiar. I’m talking about your tank, with some particular caveats for international travel. If you’ve planned ahead and paid attention to the details, you can carry an extra balance for several months without incurring any additional fees.
