Stellwagen Bank, outlined in red, is located only 25 nautical miles from Boston and three nautical miles from Gloucester and Provincetown.

Located at the mouth of Massachusetts Bay, only 25 nautical miles from Boston and three nautical miles from Gloucester and Provincetown, lies Stellwagen Bank, an underwater plateau that is home to a wide variety of marine life and is one of New England’s special ocean places. Stellwagen has been known for its highly productive fishing grounds since the early 1600s, and it is one of the few remaining hotspots of the Atlantic wolffish, a bottom-dwelling fish with a distinctive mouth full of sharp and wayward teeth that is facing extinction in the United States. However, because of its heavily-trafficked location and desirable biological abundance, Stellwagen has been faced with a multitude of human-induced pressures, leaving its ecosystems at risk. Species such as the wolffish, along with commercial species such as cod, are threatened when modern fishing gear is dragged along the bottom of the ocean, leveling the seafloor and destroying habitat features like biogenic depressions, burrows, nooks or small caves that allow fish to hide to catch prey, avoid predators, and protect their eggs.

In 1992 Stellwagen Bank was designated as a National Marine Sanctuary, which  meant that some harmful activities (including sand and gravel mining, drilling for oil and natural gas, and discharging pollutants) were prohibited – but all fishing activities were allowed to continue. In 1998, however, an amendment to the groundfish fishery management plan established a closed area in the Gulf of Maine (the Western Gulf of Maine Closure, or WGOMC) that overlaps Stellwagen and prohibits the use of particularly destructive bottom-tending fishing gear within its boundaries. (Recreational fishing and less-destructive commercial fishing are still allowed within the closure.) The idea behind this closure is that if gear that destroys the sea bottom is kept out, ocean wildlife and features on the seafloor will have the chance to rebuild and a rebuilt thriving benthic habitat will mean healthier fish stocks.

If the WGOMC has this desired effect, it will be important not only for the marine life within its boundaries, but also as an indication that this strategy should be replicated in other areas in need of protecting and rebuilding ocean communities and associated managed species. A recent NOAA National Marine Sanctuaries report compares protected areas within the WGOMC with areas of initially similar habitat type outside the WGOMC for the period 1998-2005 to see if the closure was indeed having a positive effect. What do the results say? Overall, the study’s findings indicate that the fish and wildlife inside the WGOMC closure area are recovering from impacts of destructive fishing gear. However, the report cautions that the seafloor community is changing over time and may not attain a stable state (in theories of ecology, ecosystems change over time until they reach a final, stable phase). Still, the WGOMC is recognized as an important area for conserving biodiversity, and the report concludes that the use of closures remains a valuable tool for maintaining ocean habitat. While this certainly indicates that further study of the WGOMC is needed and that recovery is not complete, it also supports the case for protecting vulnerable underwater habitats in order to allow our healthy ocean ecosystems to grow and thrive.

On August 21st, the Thai based energy company PTTEP announced that a “crude oil gas leak incident occurred” in the Timor Sea about 155 miles northwest of Western Australia.  The energy company’s press released continued that “the size of the spill is not known.  Aproximately 40 barrels of oil were discharged from the wellhead in the initial incident.”  In the ensuing month, it has become clear that this oil spill is much more serious than initially thought:

1. As of September 25th, photos from NASA satellites document that the oil slicks and sheen from the spill covered 9,870 square miles, an area even bigger than the state of Vermont.  Part of the oil sheen has been moving perilously close to the Cartier Island Marine Reserve.
2. According to conservative estimates by the World Wildlife Fund, the rig has been leaking 400 barrels a day — over 14,000 barrels since late August.  That equates to about 600,000 gallons of oil.
3. When the spill was first reported, the government of Australia predicted it would take 7 weeks to clean up.   Already, it has been 5 weeks and the spill isn’t contained.

This devastating spill may be a world away but US ocean waters, including Georges Bank and the rest of the Gulf of Maine, are also at risk because they no longer are protected from the devastating impacts of oil and gas extraction. As a parting gift before leaving office, President Bush lifted the Presidential Moratorium on drilling for oil and natural gas on the Outer Continental Shelf that had been in place since 1990.  On September 30, 2008, Congress followed suit and lifted a longstanding legislative ban on offshore oil and gas leasing as part of a large government operations appropriations bill.  As a result, important habitat in the Gulf of Maine, including Georges Bank — one of the world’s premier fishing grounds — is at risk of industrial scale fossil fuel energy development.

As the Saudi oil fields are tapped out, there is increased pressure to drill in remote areas of the ocean.  For example, at the beginning of September, BP announced a “giant oil discovery” 35,055 feet below the Gulf of Mexico seafloor, which itself is already 4,132 feet below the surface of the ocean.  In an ironic twist of fate, just as the ocean is beginning to bear the brunt of the impacts of climate change (see my earlier blog post on ocean acidification), oil companies are stepping up efforts to locate and drill for oil and gas under the seafloor.

Clearly we need energy — but how do we design a sustainable, climate neutral ocean energy solution that will not put important marine wildlife, habitat and ecosystems at risk? As Greg Watson, then a VP at the Mass Technology Collaborative, noted, New England (and Massachusetts in particular) is “the ‘Saudi Arabia of Wind.’” Of course, we need to responsibly tap this renewable resource — we can’t build wind farms wholesale across the region just because there is a lot of wind on the ocean.  Rather, we need to engage in a thorough marine spatial planning process whereby different human uses and ecological resources are identified and mapped and responsible renewable energy development is sited in a way that doesn’t create unreasonable impacts on those activities or natural resources.  Massachusetts is in the process of doing just that — and has released the first in the nation Draft Ocean Management Plan.  In Maine, the governor appointed an Ocean Energy Task Force to evaluate how to develop offshore renewable energy.  Rhode Island is working on an Ocean Special Area Management Plan (SAMP) in part to promote offshore renewable energy development.  Finally, at the federal level, President Obama issued an Executive Memorandum calling for a national ocean policy and marine spatial planning  framework.  CLF is working on all of these issues.

Imagine if all of Vermont were covered in an oil spill.  Well it has been over a month and an equally large spill in the Timor Sea hasn’t been contained.  Oil and gas drilling is still a risky business and, thanks to former President Bush and Congress, these projects are allowable in US ocean waters.  A concerted effort is needed to make oil and gas drilling old news.  We need to usher in a new era of responsible, climate friendly, renewable ocean energy development.  Help CLF make this a reality!
