The post-oil spill Gulf of Mexico

As some of you probably remember, there was an oil spill in the Gulf of Mexico last year. You can be forgiven for not remembering it, as our news media hasn’t been talking about it very much lately. In fact, if your only source of oil spill news was the mainstream media, you probably think that the Gulf is doing great! A little over a year ago, CNN ran a story about how the BP oil well that caused the spill was “effectively dead” and was “no longer a threat to the Gulf”. CNBC (and many others) ran stories about how 75 percent of the oil from the spill was gone from the Gulf. Bloomberg reported that the Gulf would recovery completely by 2012. London’s Telegraph celebrated a dramatic recovery after only one year. Whew… things aren’t as bad as we feared, and the Gulf has almost totally recovered! Or has it?

10 misrepresentations about climate change

Science

Few scientific fields generate as much controversy as climate change. Misunderstandings, misrepresentations, and outright lies are common. While environmentalists rightly criticize anti-global warming activists for not being truthful, neither side is innocent. Presented here are five common misrepresentations from both sides and the truth about those issues.

Thorny skate protection: NAFO falls short

September 26, 2011 David Shiffman

Conservation, Science

Last week, I previewed the annual NAFO meeting. Two elasmobranch conservation measures (reducing the Total Allowable Catch for thorny skates to the level that the scientific council recommended and requiring fishermen to report the species of the sharks they catch) were to be discussed. That meeting is now concluded, and the results, while not … Read More “Thorny skate protection: NAFO falls short” »

For this week’s edition of Shark Science Monday, check out this video of a presentation I gave at the 2nd International Marine Conservation Congress last May. My talk focused on how social media technology can benefit (and has already benefited) the shark conservation movement. It was part of a symposium organized by the IUCN Shark Specialist … Read More “Shark Science Monday: WhySharksMatter discusses social media and shark conservation” »

All eyes on Halifax: Will fishery managers follow scientific recommendations to protect the thorny skate?

September 19, 2011September 19, 2011 David Shiffman

Conservation, Science

Later today, the annual meeting of the Northwest Atlantic Fisheries Organization (NAFO) begins in Halifax, Nova Scotia. The marine conservation world should pay close attention. NAFO made history in 2004 by becoming the first regional fisheries management organization to set a shared quota for a shark, skate, or ray fishery, but the future of that legacy is in question.

Proposed fishery increase could harm critically endangered thorny skates

September 15, 2011 David Shiffman 14 Comments

Conservation, Science

In response to new analyses estimating that greater numbers of some skate species can be safely fished, the National Marine Fisheries Service has proposed an “emergency” increase in the catch limit for the Northeast Skate Complex Fishery. While its good news that some skate populations may be doing well enough to support increased fishing, this doesn’t tell the whole story of the Northeast Skate Complex.

Book review: Discoveries of the Census of Marine Life

September 14, 2011September 14, 2011 David Shiffman 1 Comment

Science

The Census of Marine Life is undoubtedly one of the most amazing scientific collaborative efforts of all time. All told, thousands of scientists from more than 80 countries participated in the decade-long project. They discovered thousands of new species, published thousands of papers, created and perfected new research techniques, and added countless datapoints to important databases- many of which are free and accessible online. The story of the COML is nothing short of incredible, and it is told wonderfully in the new book “Discoveries of the Census of Marine Life: Making Ocean Life Count.”
