Radial Symmetry – the poetry of Katherine Larson

What is it about the ocean that inspires otherwise precise and stoic scientists to cast off the shackles of structured, rigorously defined scientific language and swim, instead, through a sea of verse and meter. You can find examples littered across the internet, from Kevin Zelnio’s song lyrics featured in the Open Lab, to my own pedestrian attempts at Hardtack and Sardines. Of course, some poets rise above our amateur attempts and merge a deep understanding of the natural world with a precise eye for beauty, bringing both together in a sea of verse which stirs the soul and challenges the intellect. That is exactly what Katherine Larson has done with her first book of science-inspired poetry: Radial Symmetry.

It may seem a strange book for a marine science blog to review, but Larson, a molecular biologist by training, has captured a the spirit of scientific inquiry and the ocean in a way that few other mediums can. Her poetry evokes the thrill of discovery as well as frustration. How many practicing scientists can’t relate to Love at thirty-two degrees, a poem that begins by observing the branchial hearts of a squid, when she announces:

U.S. Ocean Policy Takes a (Small) Step Forward

Earlier today, the National Ocean Council released a new Implementation Plan for the National Policy for the Stewardship of the Ocean, Our Coasts, and the Great Lakes. We asked our colleague Morgan Gopnik, formerly a senior advisor to the U.S. Commission on Ocean Policy, to summarize this new plan.

Today marks a momentous and long-awaited milestone for true ocean policy geeks: at noon the National Ocean Council released a draft Implementation Plan for the National Policy for the Stewardship of the Ocean, Our Coasts, and the Great Lakes! If this announcement makes you yawn, you are not alone. But wait! This new Plan could be truly significant for anyone who cares about ocean ecosystems and resources or coastal communities. Let me explain.

As most readers of Southern Fried Science probably know, the last decade has produced many depressing stories about declines in ocean health: overharvested fish stocks, waning biodiversity, “dead zones,” invasive species, oil spills, etc. It has also produced a number of studies and high-level Commission reports suggesting solutions to these problems, most notably the U.S. Commission on Ocean Policy’s “Ocean Blueprint for the 21^st Century,” released in September 2004. (Full disclosure: I served as Senior Advisor to the Commission.) The Blueprint provided lots of recommendations (212 in all) about controlling pollution, managing fisheries, protecting shorelines, and addressing other specific problems. But its major theme and most significant contribution was to emphasize the need to fundamentally change our approach to ocean management and governance.

Aquaculture in North Carolina: NC State’s Marine Aquaculture Research Center

This year we’re starting a new series highlighting the many faces of aquaculture in eastern North Carolina. From research facilities to new species under domestication to large facilities to feed the masses, there’s a lot going on in the state’s low-lying coast. Periodically, we’ll visit one and bring you pictures and stories from the operation. Stay tuned for more.

Tucked on the banks of Sleepy Creek between the two small towns of Marshallberg and Smyrna, NC, a world of new aquaculture ideas grows – NC State’s Marine Aquaculture Research Center. A single building with large tanks behind emerged from the landscape as we drove down the dirt farm road that connects the property to the main road. Originally planned as a three-building complex, recent budget cuts felt throughout the state have made the operation smaller – but no less important. The facility houses projects for anyone with an idea for how to forward aquaculture in the 21st century – be they local researchers, students, or people already in the industry. The two major projects happening during our visit are a comparison of hybrid and striped bass feeding efficiencies at a variety of temperatures and continuing development of a waste-management strategy for tank effluent water. There was also a red porgy mating effort and mud minnow spawning setup.

Get marine conservation into the national political conversation with Americans Elect!

Conservation

In response to the partisan gridlock in Washington DC, a group called Americans Elect hopes to “open up the political process”. This organization, founded by heavy hitters from both parties, is using the internet to allow anyone registered to vote in the United States, regardless of political affiliation, to nominate candidates for President of the United States. An online convention in June, which every registered Americans Elect user can participate in, will determine the nominee. who will be on official ballots in every state alongside Barack Obama and the Republican nominee (probably Romney but we’ll see).

Additionally, any registered Americans Elect user can propose a question. The top questions, as voted on by all other Americans Elect users, will have to be answered by any potential candidate. These top questions, and the Americans Elect candidates’ responses to them, will undoubtedly attract national media coverage. Presently, most of the top questions are about the economy and foreign policy. None focus on the oceans.

I have submitted a series of marine conservation questions, and I need your help to get them enough votes to earn them “top question” status and get marine conservation into the national political conversation! If you are registered to vote in the United States, please consider registering for Americans Elect and voting for these questions.

New app: Learn about great white sharks while supporting research

January 11, 2012 David Shiffman 4 Comments

Science

Earlier today, the Marine Conservation Science Institute launched a new iPhone and iPad app focusing on great white sharks. The app, called Expedition White Shark , includes numerous features that let users learn more about these amazing animals.

A game (called “Shark Life”) lets you learn about the life history of great white sharks by controlling a virtual baby great white. Users explore the marine environment near Southern California white eating fish and avoiding threats like gillnets and pollution.

A “news” interface lets you keep up to date on some of the latest exciting discoveries the Marine CSI team makes, and you can learn more about great whites from the “facts” tab. The app also includes numerous photos and videos of great whites and the research team in action.The coolest feature this app contains, however, is the ability to track satellite-tagged great whites.

Updates from the Deep: New and Noteworthy in Hydrothermal Vent Research

From hairy-chested yeti crabs to the deepest known fields, hydrothermal vents have been enjoying a bit of science celebrity in the last few weeks. Beneath the headlines, there has been an eruption of vent-related research published in the scientific literature and some exciting new expeditions just left port.

The Discovery of New Deep-Sea Hydrothermal Vent Communities in the Southern Ocean and Implications for Biogeography

The exhaustive author list on this paper reads like a who’s who in hydrothermal vent biogeography. This is the paper that introduced “the Hoff” crab to the world, but the findings are far more significant. Hydrothermal vent systems are sorted into biogeographic provinces, with different regions supporting different communities. The iconic giant tube worms dominate the eastern Pacific, while the western Pacific (prominently featured in Deep Fried Sea) plays host to fist sized snails, and the Atlantic features shrimp as its dominant species. There are several missing gaps in our understanding of how these qualitatively different communities are connected – the Southern Ocean, the south Atlantic, the Indian Ocean, and the Cayman Trough, among others. Filling in these gaps in our knowledge can help us understand the history and evolution of hydrothermal vent ecosystems.

Bipartisan Fisheries Policy: A Worldwide First

According to the Washington Post, the US has overcome bipartisan politicking long enough to enact amendments to the Magnusen-Stevens Act that puts all fishery stocks into management – not just those threatened by overfishing. In practice, that means each stock has an absolute maximum catch limit for 2012. Perhaps the most resounding success of this policy is that it actually addresses scientific criticism of current management (covered fairly well by MAST) that implementing catch limits for one species just shifts fishing effort to other species – which then must have yet another species-specific policy put in place after overfishing occurs. Implementing fishery management plans for all fishery species at once eliminates the by-the-seat-of-your-pants feeling that previous US management conjures.

Last week, a team of 10 Australian scientists announced that they had found the world’s first “shark hybrids”, offspring of individuals from two different shark species which had interbred. During a routine survey of Australian marine life, 57 sharks were found that physically resembled one species of shark, but had genetic markers inconsistent with that species. Subsequent genetic investigation revealed that these 57 animals were hybrids between common blacktip sharks (Carcharhinus limbatus) and Australian blacktip sharks (C. tilstoni).

Some of these hybrids were “F1″, meaning that one parents was a common blacktip and one was an Australian blacktip. Others were “B+”(backcrossed), which means that one parent was a common blacktip/Australian blacktip hybrid, and the other was a “purebreed” of one of those two species. According to the study’s lead author, Dr. Jess Morgan of the University of Queensland, “our genetic marker tells us that these hybrids are ‘at least’ F1, and that these animals are reproductively viable and can produce an F2…the hybrids may be generations past F2 but the existing genetic markers can’t distinguish how many generations past the second cross have occurred.”

Fishing on Your Phone: Apps for the Ocean-Savvy

In recent months, I’ve been hearing snippets of conversation about the use of smartphones for lots of things involving fish: guiding seafood choices, fishing identification, even reporting to the state. Most are free, some cost money, and there’s a bunch that haven’t reached the Android market yet (so no review from me). Feel free to add your own reviews, and iPhone users out there – add to the sketch of a review here. Here’s the results of my app playing:

The Green Seafood Guide

by Lificious Software, cost: free

Start by browsing a list of “highly recommended”, “good choices”, or “to avoid” for either seafood or sushi – or search for a particular species in the search bar. Either the lists or your search results will link you to the appropriate information sheet on the Monterey Bay Aquarium website. The Aquarium facts sheets aren’t exactly smart-phone friendly, so the text comes up small, but it’s manageable. The search left something to be desired, as a search for “clams” offered me just the farmed variety and routed me directly to these fact sheets rather than telling me the basics firts. The app itself is fairly streamlined and straightforward, with just one basic home screen that also boasts a button “What should I eat today”, that from what I can tell provides a random suggestion from the “highly recommended” seafood list. I’m guessing this is an alternative interface to the Monterey Bay Aquarium’s more clunky app. Overall, it’s no more helpful than the card the Aquarium puts out, but less easy to lose and offers links to more information should you feel so compelled.

Kakapo: The world’s largest parrot and the birth of active conservation

January 4, 2012 David Shiffman 8 Comments

Our world is facing a biodiversity crisis so severe that many scientists have labeled it as the sixth great mass extinction in Earth’s history. Conservation efforts to date have focused on endangered species and “biodiversity hotspots” , relatively small areas with large numbers of species. Most of these hotspots are in areas you’d expect them to be, places like coral reefs and tropical rain forests. One surprising biodiversity hotspot is New Zealand.

Though New Zealand is best known for it’s two largest islands, the country has over 700 islands larger than one hectare. Additionally, New Zealand is isolated- hundreds of miles of Pacific ocean separate it from Australia, and it’s farther still from Asia or South America. Similar to the Galapagos, this isolation has led to an extremely high rate of “endemic” species, plants and animals that are native to an area and aren’t found anywhere else on Earth.

New Zealand is particularly famous for its unique birds. You may have heard of the kiwi, a word which has become slang for a New Zealander*, but this nation is also known as the “seabird capital of the world“. In total, there are more than 60 endemic bird species found there.
