Over 15 years of ocean science and conservation online
If you’re coming over from CollegeScholarships.org to check out some of David Shiffman’s work before voting for the 2011 Blogging Scholarship, welcome! Here are a selection of some of David’s influential, informative, and award-winning posts.
If you’ve never been to Southern Fried Science before and want to get an idea of who this Shiffman bloke is and what he’s about (hint: it has something to do with sharks), check out his two bench-mark posts:
A few weeks ago, I wrote about a proposed shark cull in Western Australia and asked for your help to oppose it. By the end of the Support Our Sharks anti-cull campaign, the petition had almost 19,000 signatures from dedicated shark conservationists from around the world, including many of our readers. After some initial anti-shark … Read More “Cull canceled: victory for the sharks of Western Australia!” »
Manta rays are true gentle giants; though they can grow more than 20 feet wide from wingtip to wingtip, they eat only plankton. Swimming with these animals is a rare thrill for SCUBA divers, and manta-viewing ecotourism is worth over $100 million each year. Like many species of sharks, manta rays grow slowly and reproduce … Read More “Threatened gentle giants: both species of manta ray added to the IUCN Red List” »
#SciFund is a month-and-a-half long initiative to raise funds for a variety of scientific research projects. Project leaders post a project description and an appeal for funds, and members of the public are invited to make small donations to projects that they deem worthy. Donations come with rewards such as access to project logs, images from … Read More “#SciFund Challenge: Saving Hawaii’s Coral Reefs” »
Yesterday, the Atlantic States Marine Fisheries Council voted to reduce the catch of Menhaden by as much as 37%. Menhaden, often referred to as the “most important fish in the sea” have been declining precipitously over the last several decades, due largely to the Menhaden reduction industry, which is now supported by a single company. Several graphs have been produced recently to illustrate this decline, including this incredibly informative illustration. Despite this attention, most of these reports have missed the big picture. Amy and myself have been thinking quite a bit about shifting baselines recently, and Menhaden represent what may be the most extreme example of this phenomenon.
The population of Menhaden along the eastern seaboard crashed in 1879 a full century earlier than the decline documented here. In it’s heyday, the menhaden industry was catching seven hundred million fish annually. Last years harvest was barely 450 million. These numbers belie a massive ecologic change. While the historic menhaden industry was based north of Cape Cod, our current menhaden production focusses on the mid-Atlantic seaboard and is slowly moving south, chasing the remaining fish. The population that today has finally received protection is a remnant of the once massive foundation of the pelagic ecosystem.
Reprinted below is our original article, the Menhaden of History.
As Halloween welcomed the world’s seven billionth person, there has been renewed interest in meeting the food, shelter, and water needs of a large and growing global population. One recent article in the Washington Post (10/30/11) attempted to make 7 billion a tangible number that kids can wrap their minds around by describing 7 billion M&M’s filling three Olympic-sized swimming pools. While I think this is a useful exercise, when thinking about 7 billion people, not all people can be counted equally. In terms of resource use, each of the over 300 million United States citizens are like bloated, entitled M&M’s squeezing their smaller brethren out of the pool.

This weekend I assembled a small team of marine and environmental scientists, including a molecular ecologist, a human geographer with experience in environmental justice, a political ecologist with experience in common-pool resource theory, and a veteran of the US Commission on Ocean Policy with extensive experience in marine spatial planning, to test out the new expansion for Settlers of Catan, Catan: Oilsprings. Settlers of Catan is a popular and expansive board game that focuses on resource management, development, and trading. Oilsprings is designed to add an element of “Tragedy of the Commons” to the game by introducing a new resource, oil, which allows rapid development, but at a cost that affects all players.

Our friends from the fantastic ocean acidification documentary A Sea Change are working on an important new project. It’s called “Shored Up“, and it’s all about sea level rise and the strategies that coastal communities are using to try and keep their beaches.
One issue in particular, beach renourishment, has major environmental implications that aren’t often considered. Sand provides critical habitat for organisms other than tourists, and not all sand is the same: it differs in grain size, chemical composition, and other variables. Organisms that are adapted to one type of sand, such as beach-dwelling crabs and snails, often struggle to survive in another that’s dumped in huge quantities in their habitat. Additionally, the ecosystem where the sand comes from is often greatly disturbed by the huge sand-collecting dredges.
The movie doesn’t just focus on renourishment, however:

In an attempt to garner attention and raise awareness regarding the problematic use of orcas and other marine mammals in captivity for entertainment, PETA, an animal rights group, has sued Sea World, a corporation that builds and manages aquariums and marine parks. Opposition to Sea World’s brand of entertainment-driven aquariums is nothing new, but this fresh lawsuit adds a novel twist to the boilerplate “intelligent animals don’t belong in captivity” – PETA is suing Sea World for violating these oceanic dolphin’s constitutional rights under the 13th amendment.
The 13th amendment to the United States Constitution explicitly outlaws slavery or involuntary captivity:
One of the main themes of the Republican Presidential primary campaign has been that government regulations- specifically, regulations designed to protect the environment and public health from industrial pollution- is damaging to the economy. Nearly all of the Republican Presidential candidates have expressed this view: Rick Perry wants to “lock the doors and turn off the lights” at EPA headquarters, Michelle Bachmann thinks it should be called the “job-killing organization of America“, and both Newt Gingrich and Herman Cain want to abolish the agency entirely.
Is there any truth to the idea that environmental regulations cost jobs and are slowing the economic recovery? On it’s face, the idea makes sense. A business has a finite amount of money, and the more money they have to spend on complying with environmental regulations, the less money they can spend on hiring workers. If a business has to pay for new technology to reduce the amount of pollution their manufacturing process produces, the money spent on that technology is money that can’t be spent on new workers. The real question, though, is not whether there are costs to environmental regulations- there obviously are, and they can sometimes be quite high to particular industries. The real question is whether the benefits of these environmental regulations outweigh the costs.
