Fisheries governance and sustainability
An interesting new paper by a group at Dalhousie University compares several key aspects of fisheries management with a measure of the probability that fisheries are sustainable. The authors conclude that “policy transparency” is more strongly related to sustainability than scientific robustness, implementation capability, or the extent of subsidies, overcapacity, and foreign fishing. The measure …

CONTINUE READINGThe end of the Exxon Valdez legal saga?
Rick earlier posted about the 20th anniversary of the Exxon Valdez oil spill. This week, the Ninth Circuit may finally have brought the litigation that followed that spill to a close. You may recall that last year the U.S. Supreme Court heard Exxon’s challenge to the punitive damages award against it, which had been set …

CONTINUE READINGNational ocean policy under construction
President Obama today proclaimed June 2009 to be National Oceans Month, a time to “celebrate these vast spaces and the myriad ways they sustain life.” The proclamation calls on “all Americans to learn more about the oceans and what can be done to conserve them.” Beyond that symbolic move, Obama took an important step toward …

CONTINUE READINGAcid oceans coming to a beach, and theater, near you
Global warming has gotten so much attention lately that the public has largely overlooked another, independent consequence of rising CO2 concentrations: acidic oceans. As discussed by Dan earlier this year, for many years the oceans have been silently absorbing CO2 and thereby buffering against even higher atmospheric GHG levels, staving off more warming — but with potentially devastating consequences …

CONTINUE READINGSave the Tuna!
Amid concerns about the possible exhaustion of tuna stocks, Science reports on a positive step: Representatives of Western Pacific island nations last week put the finishing touches on a series of bold new measures aimed at saving the world’s last great tuna stocks. Last May, the group decided to bar fishing in two huge pockets …

CONTINUE READINGGlobal warming winners? (oceans edition)
By now it is widely recognized that ocean warming and acidification caused by rising CO2 levels will adversely affect many organisms, especially those that depend on calcium carbonate shells. But there may be winners as well. Rebecca Gooding and a group from the University of British Columbia report in the Proceedings of the National Academy …

CONTINUE READINGSharing the catch
According to Science Insider (subscription required), NOAA Administrator Jane Lubchenco has endorsed broader use of a “catch shares” approach to allocating the available catch in commercial fisheries. The shares strategy (also referred to as “individual transferable quotas” or “limited access privileges”) gives individual participants in the fishery a permanent and transferable right to a set …

CONTINUE READINGSea level falling in places — but change still problematic
This morning’s New York Times has this story by Cornelia Dean describing the changes global warming is bringing to Juneau, Alaska. While sea level is rising relative to coast lines in many parts of the world as ocean waters warm and expand, the opposite is happening in and around Juneau. As the region’s glaciers recede, …

CONTINUE READINGA framework for offshore renewable energy
Cymie posted here about the hearings Interior recently held in on both coasts on offshore energy development of all stripes. True to the President’s commitment to making renewable energy development a priority, shortly after those hearings Interior’s Minerals Management Service finalized regulations governing renewable energy development on the outer continental shelf. The regulations, developed under …

CONTINUE READINGIs an ocean acidification TMDL on the (distant) horizon?
In January, Dan posted on the problem of ocean acidification and Sean noted that a lawsuit by the Center for Biological Diversity had convinced EPA to look into the possible application of the Clean Water Act. Now EPA has issued a call for interested parties to submit information as it considers whether to tighten its …
