Over 15 years of ocean science and conservation online
We interrupt our regularly scheduled marine science and conservation discussions and frequent Aquaman adulation to bring you this important announcement: “My legs creak as I climb the stairs to our meeting room. I lean against the wall to steady myself. I could have taken the elevator, saved myself the pain, but I need to heal. … Read More “Who are “The Lucky Ones”?” »
Long-time readers know that I am a dedicated fan of the one true king of Atlantis, Arthur Curry–Aquaman. Since his reboot in DC Comic’s New 52 series, Aquaman has risen above the Justice League pantheon, casually crushing his critics with humor, style, and pure, aquatic power. My original plan was to review the marine science in Aquaman, but, since the Trench, our hero has spent relatively little time in the sea. We can forgive that. Between protecting his old gang, the Others, from arch-nemesis Black Manta, and saving the surface dwellers while reclaiming his crown in Throne of Atlantis, Mr. Curry has been quite busy.
Now, with Aquaman #17, it looks like things are about to change.
So, this is pretty much my all time favorite piece of comic book art. I love that so many invertebrates get starring roles–colossal squid, octopuses, crustaceans of all sorts. I love that whales are relegated to the background, dolphins are barely more than shadows, and elasmobranchs other than sharks are prominently featured. Artists Paul Pelletier and Art Thebert did a fantastic job creating an ocean biodiversity tableau that shuns the Wyland-esque tropes characteristic of the genre. This is a tough, gritty Aquaman. His ocean is not all sunsets and dolphins.
This also settles the longstanding debate about Aquaman’s telepathy. Aquaman talks to fish. Whether they talk back is a different story.
Right now, delegates from 178 countries are meeting in Bangkok, Thailand to discuss a variety of conservation proposals. At the 16th CITES Conference of the Parties, among many other worthy topics, delegates will be debating a record-number of shark and ray proposals. These include iconic species like hammerhead sharks (3 species) and manta rays (2 species), as well as oceanic whitetip sharks, porbeagle sharks, and three species of freshwater stingray.
In addition to a record-number of shark and ray proposals, this year’s Conference of the Parties also has a record-number of attendees live-tweeting the meeting.Those of you who follow me on twitter know that I’ve been re-tweeting lots of information about CITES and these shark conservation proposals. In case you want to get the information directly from the source, I’ve prepared a guide to following along with the meeting on twitter.
1) Follow #CITES . Though this hashtag isn’t exclusively focused on sharks (and isn’t exclusively in English), there’s a lot of good information being shared.
2) Follow #Cites4Sharks . Also use this hashtag if you’re sharing any relevant links or information.
3) Follow the 13 accounts I’ve highlighted below (and let me know in the comments if you have suggestions for any accounts I should add to the list):

I have a few important updates to share about ScienceOnline Oceans! For those of you who haven’t yet heard, ScienceOnline Oceans is a conference (affiliated with the NC-based ScienceOnline) that will explore how marine scientists and conservationists can use the internet for collaboration, education and outreach. The meeting will take place October 11-13th at the University of Miami (Miami, FL), and will include an expert panel discussion on current ocean conservation issues, a day of conference-style programming, and a day of field trips allowing attendees to explore south Florida’s marine environment. Scientists who want to learn more about collaboration and outreach applications of the internet are welcome, as are science communicators who want to learn more about ocean issues.
1) The Planning Wiki is now online, and will be until April 1st! If you have an idea for a session, now is the time to submit it! For those of you new to the ScienceOnline community, theplanning wiki can be thought of as similar to a traditional conference submission page, but there are three important differences:1) everyone can see what everyone else has submitted, 2) anyone can add to what anyone else has written (including questions, suggestions, etc.), and 3) the person who proposes a session can, but does not have to, actually run that session- you can simply suggest a topic that you’d like to see discussed and ask people to volunteer to run it (and you can also volunteer to help run sessions that others have suggested).
We are offering four kinds of sessions at ScienceOnline Oceans. Skills workshops (taught by a hands-on leader to help people learn a skill), panel discussions (3-4 experts on a topic sharing their expertise, possibly including time for audience questions at the end), directed discussions (led by 1 or 2 discussions leaders, primarily consisting of the audience asking questions of the discussion leaders), and facilitated conversations (unconference-style discussions, essentially discussions between audience members facilitated by 1 or 2 moderators, which can be a follow-up to a panel discussion or directed discussion). Here is the link to the planning wiki.

A new study* has estimated that the total number of sharks killed by fisheries each year is between 63 and 273 million, with a average of approximately 100 million.In an interview, lead author Dr. Boris Worm explains the importance of this estimate:
“This is by far the most comprehensive estimate of shark mortality yet,” he said, “because we consider all sources of mortality, from direct fishing, finning, and discard mortality. the estimate was derived by crunching numbers from almost 100 publications on the catches and mortality of sharks.”
Of all the numbers this team crunched, the most important thing to consider is whether the exploitation rate is greater than the rebound rate. In other words, is this level of exploitation more than the populations can recover from? Though many estimates and approximations went into calculating these figures, it seems quite clear that sharks are being harvested at an unsustainable rate.
At 7 AM EST on Monday, February 25, the ROV Isis rose from the depths of the Cayman Abyss, bringing to a close the 82nd cruise of the RRS James Cook. During JC82, we explored two recently discovered hydrothermal vents fields in the Cayman Trough: Von Damm, named for the late marine geochemist Karen Von Damm, and Beebe, named for the 20th century explorer William Beebe. By any measure, JC82 was a massive success. The samples and videos we’ll bring back will provide ecologists, geologists, and chemists with new insights into fundamental ocean systems for years. The images alone, some beautiful, some heart-breaking, have already inspired.
Since I last updated the blog on our adventures exploring the Cayman Trough, we’ve had a steady stream media coverage, most of which has been excellent, some of which has been… strange. It’s been fascinating watching the articles come out, seeing what different media outlets consider the story, and, most important to me, getting a chance to share our adventure with a wide audience. Now that the #DeepestVents cruise is officially over (and we’re in transit to yet another, equally exciting bolt on cruise to investigate submerged lava flows off the island of Montserrat), I thought it would be a good opportunity to reflect on the cruise, the story, and how the media shaped it.

Endangered species seem to be coming up around here more often than usual, mostly due to the potential state-level listing of great white sharks in California. This move has been resisted from some surprising corners, including researchers who are generally pro-shark conservation. The reasons why scientists might want to oppose an Endangered Species listing are laid out by Dr. Chris Lowe in an earlier post on this very blog, so I won’t reiterate all of them here. Surprisingly, I have yet to see any comments accusing Dr. Lowe of being a shill for the drift gillnet fishery.
There seems to a be a real sense among some conservation-minded folks that Endangered Species listing is something of a “holy grail” for species protection and recovery, and some petitioners would have you believe that anything less is unacceptable (and probably the result of corruption). However, the Endangered Species Act has a very specific process by which species receive protection, and a defined set of limitations. A lot of well-meaning people seem to have limited knowledge of this process and limitations. To do my little part to help fix this, this post will be a short primer on the Act and will show how a marine species has recently navigated the entire process for listing. With any luck, maybe this will result in one or two fewer misguided online petitions.

Online petitions have become a popular tool of the conservation movement. A well-written petition can be an important tool for helping to shape policy, particularly when used as part of a larger and well-organized lobbying and advocacy campaign. Many petitions, however, are so badly written as to be ineffective or even counterproductive when it comes to influencing real policy change. Even worse, they falsely perpetuate the idea that an activist has “done something” about the problem, which may prevent them from participating in a process that could result in real change.
In case you want to join the numerous activists who are filling my Facebook news feed and e-mail inbox with useless petitions, here is an easy 5 step guide for you to to follow, using examples from some real petitions I’ve been asked to sign.
A note on terminology: Petitions typically contain a few basic elements, which I term here “the problem”, “the target”, and “the solution”. The problem briefly describes the undesirable situation that the petition hopes to remedy. The target is who the petition is directed at. The solution is what should be done about the problem.

I’m Iris, and I used to blog over at From Alevin to Adult. An alevin is a newly-hatched salmon and, as you might guess, my current research is fairly salmon-centric. I’m studying factors that influence estuarine and early marine growth of salmon, and how growth links to overall survival.
Salmon are anadromous, meaning that they move between freshwater and saltwater at different stages of their lifecycle and, as such, they depend on a variety of habitats. Furthermore, salmon are often subject to intense size-selective mortality – meaning that a fish’s growth can determine whether or not it survives. Several studies have shown that the time spent and size gained in estuarine and early marine environments affect overall survival for salmon. Growth is largely determined by feeding success, and faster early marine growth has been associated with higher marine survival for salmon.
So, what could influence salmon feeding in these early life stages? Surely what they’re eating might play a role – where is their food, and how much food is there?
Environmental stressors may affect feeding. High temperature and low-oxygen waters can be inhospitable to salmon. This can physiologically affect the fish so that it does not get as much net energy from its prey, or it can prevent the fish from reaching its prey altogether.

Dr. Chris Lowe is a Professor of Marine Biology at California State University Long Beach, and is Director of the CSULB Shark Lab. He has studied California’s great white sharks for more than 10 years, and has written more than 75 peer-reviewed scientific publications. Dr. Lowe also serves on the Board of Directors for the American Elasmobranch Society, the world’s largest professional organization of shark scientists. The following guest post was also submitted as a public comment to the California Department of Fish and Wildlife.
Comments for consideration on the petition to list white shark as threatened or endangered species:
I am a Professor of Marine Biology and the Director of the CSULB Shark Lab at California State University Long Beach and have been conducting State and Federally permitted white shark research in California since 2002. In addition, as a professional and published shark scientist who has studied a variety of shark species around the world, including white sharks in California, I would like to take this opportunity to express my personal professional opinion in regards to the petition request and the science behind it.
