Ecology Admits Science "Is Not There" to Claim Oyster Deaths
Published:2014-10-29 Column
Ecology Admits Science "Is Not There" to Claim Oyster Deaths As Governor Inslee prepares to release his climate policy, ocean acidification has become his central argument for cutting carbon emissions. In August, the New York Times printed a profile of the Governor, noting, "Billions of baby oysters in the Pacific inlets here are dying and Gov. Jay Inslee of Washington is busy spreading the bad news." Now, the Department of Ecology says the science simply "is not there" to back up those claims, adding "we do not yet know how Pacific Ocean conditions would affect Puget Sound or coastal bays." We noted this in a blog last month. As the Governor was claiming widespread oyster death due to acidification, the Department of Ecology (DOE) was simultaneously arguing in court that there is no "conclusive evidence that Washington’s coastal aquatic life in the natural environment are being impaired by ocean acidification." Two weeks after our blog, Ecology Director Maia Bellon responded, writing on DOE's blog ECOconnect that "Ocean Acidification is real," saying quotes from Ecology's legal filing were "misinterpreted." She added, "Billions of oyster larvae have died over this past decade at Pacific Northwest hatcheries, and reproduction of wild Pacific oysters at Willapa Bay has declined." Naturally, we asked how the comments had been "misinterpreted." Mindy Roberts, a scientist who is leading DOE's ocean acidification research in Puget Sound offered to answer our questions. Put another way, acidification could be impacting wildlife but not pass the legal threshold necessary for additional protection. So, I asked what evidence there was for evidence of harm, even if it did not meet the legal threshold. Ecology candidly admitted they simply do not have any evidence. They made this point in several ways. Further, the harm to oyster larvae occurred in a nursery, not the natural environment. Finally, the study itself warned, as Ms. Roberts put it, "data gaps preclude extrapolation" to other areas. Second, Ecology is guiding an effort to improve monitoring in Puget Sound because there simply isn't enough research or data. Conclusions, made by others, about impacts to oysters in Puget Sound, therefore, are premature, citing NOAA's conclusion that it "is premature to conclude that acidification is responsible for the recent oyster failures.” Finally, with regard to the coast and Willapa Bay specifically, Ms. Roberts said that while she was not doing research there, when it comes to claiming wild oysters are being harmed due to acidification, "the research isn't there." That, however, is at odds with the claim made by Ecology Director Maia Bellon, who specifically claimed "reproduction of wild Pacific oysters at Willapa Bay has declined." Ms. Roberts said to her knowledge the only research on impact to oysters in the area was the Barton study, which was in Oregon nurseries, not Washington waters. That stands in stark contrast to the claims of the Governor, the Director of Ecology and others. For example: • In a New York Times interview, Governor Inslee said "It used to be the canary in the coal mine. Now it’s the oyster in the half shell. You can’t overstate what this means to Washington.” The Governor went on to claim that a company moved its operations out of Washington to Hawaii due to acidification impacts. Ecology's scientists, however, say there is literally no evidence to support the claim that oysters are being harmed by acidification in Washington waters. Acidification certainly is worth looking at and with competent and curious scientists leading the effort, I am hopeful and interested to see the results of Ecology's new monitoring program. The political leadership, however, often sees scientific uncertainty as a barrier to implementing their chosen policy path. They substitute attitude for science, declaring affirmatively "Ocean acidification is real," and claim "billions of oyster larvae have died" even if there simply isn't the data to make those claims in Puget Sound. Not only does that make for bad policy, it sends a message to agency scientists about the results they should produce. Knowing that the agency director has boldly declared that acidification is harming oyster larvae, there is not so subtle pressure on the scientists to find evidence that backs up that claim. There is a clear contradiction between the political messages from the Governor and Director and the science of ocean acidification. The question is whether the Governor and Director will conform to the science or whether they will make the science conform to their politics.
