Noise disrupts interdependencies in the web of life
While it is easier to evaluate specific impacts of a stimulus on specific animals, we know that nature is not just a catalog of individual species; rather it is a fabric of interdependent organisms living in interconnected physical habitats.
This point is punctuated in a recent paper on the Proceedings of the Royal Society that evaluates the noise impacts of gas well fields on the pollination and dispersal of piñon pine seedlings in New Mexico.
Gas wells use compressors which can be really noisy. The paper examines how the noise of a compressor field impacts hummingbirds that pollinate the piñons, and blue jays that disperse the piñon seeds. They found that the number of piñon seedlings were one quarter the density in the noisy compressor area than in quiet areas. This would indicate that the hummingbirds are not bothered by the noise, but the jays are.
This negative seed dispersal condition is further amplified by the fact that mice that eat the seeds are also not bothered by the noise, so that while there is no negative impact on pollination, the seeds that are produced are eaten by mice rather than distributed by jays.
This is an example of how noise disrupts a simple set of relationships between three species of vertebrates, and how the disruption impacts one species of tree.
We know quite a bit about terrestrial interdependencies because we spend most of our time “on the ground.” But we can be sure that the ocean is full of equally important interdependencies which we have yet to discover.
This adds yet another dimension we should consider as we roll unmitigated noise sources into the ocean.

National Ocean Policy released today for public review!
Today the National Ocean Council released their Draft Implementation Plan for a National Ocean Policy. This is fabulous news because the US has never had a comprehensive ocean management plan, we have just been tangled in a web of agencies each “managing” their own areas of concern – regional fisheries councils, Department of Transportation, Minerals Management, US Navy, the Coast Guard, State and Tribal agencies, the Energy Department, Marine Mammal Commission, etc., etc., etc….
The urgent call for a comprehensive ocean management plan went out almost a decade ago in 2002 with the Pew Ocean Commission report. A bit over a year later the call was again made by the US Commission on Ocean Policy. The importance of the reports lead Congress to craft complimentary ocean policy acts with Senator Barbara Boxer’s “National Ocean Protection Act” (NOPA 2005) and Rep. Sam Farr’s “Oceans 21” (2006).
The Bush administration wasn’t really big on conservation bills so while Oceans 21 was passed in the House, NOPA didn’t get out of committee. Thus it was with considerable delight for me when the newly elected Obama Administration ushered in an Interagency Task Force to come up with a comprehensive National Ocean Policy. The document released today was a product of the taskforce’s work – including hearing thousands of public comments, and reading thousands of written recommendations.
I have not yet had a chance to dig in and read the draft, but the stated objective of reconciling all national ocean interests to “be considered collectively and managed comprehensively and collaboratively” sounds like a breath of fresh air. It will be easier to assure environmental compliance, and much easier for ocean industries and other stakeholders to tailor their activities under a single comprehensive policy rather than having to appeal an array of uncoordinated regulatory agencies for approvals on their various enterprises.
What is not to like about reconciling and streamlining ocean policy? Unfortunately you will need to brace yourself for the clamor, hue, and cry of the Oilmen and their minions who will bellow about a “job-killing government power grab.” They prefer the tattered regulatory fabric that has made possible the offshore dead zones, regional fisheries crashes, the disappearing wetlands, and yes, the Deepwater Horizon oil spill.
It’s easier for big industry to game a system that is a confused mess of conflicting fiefdoms. A coordinated interagency ocean policy is more efficient, more sensible, and will be easier to drive toward a sustainable set of complimentary policies – something apparently the Oilmen don’t want.
We’ll review the document and let you know how we can all support the implementation of this long-awaited sea change in US National ocean management.
