Geohistorical records indicate no impact of the Deepwater Horizon oil spill on oyster body size

Abstract: Documentation of the near- and long-term effects of the Deepwater Horizon (DWH) oil spill, one of the largest environmental disasters in US history, is still ongoing. We used a novel before-after-control-impact analysis to test the hypothesis that average body size of intertidal populations of the eastern oyster (Crassostrea virginica) inhabiting impacted areas in Louisiana decreased due to increased stress/mortality related to the oil spill. Time-averaged death assemblages of oysters were used to establish a … Show more

“…I and C were varied using empirical estimates of the proportional change in control and impact sites in the before period versus the after period, pI and pC, respectively, sampled from 47 ecological datasets (I= λ·pI-1;C= λ·pC-1; Table ). A list of the published datasets used to calculate empirical estimates in this study are provided in the Data sources section (Burge et al, ; Dietl & Durham, ; Moland et al, ; Sepúlveda & Valdivia, ; Williams, Miller, Bright, & Cameron, ; see also Appendix ).…”

“…In response to the need for more rigorous impact assessments, many government agencies have initiated long‐term monitoring programs (Field et al 2007, Fancy et al 2009). Using such monitoring data, a before‐after‐control‐impact (BACI) statistical design (Stewart‐Oaten et al 1986, Underwood 1992, 1994), comparing affected sites with unaffected sites before and after an event, can help test for impacts such as occurred after the 2010 Deepwater Horizon spill (Dietl and Durham 2016, Lauritsen et al 2017). Recent simulation studies have reemphasized the advantages of BACI over alternative approaches such as before‐after, control‐impact and randomized control trials (Christie et al 2019).…”

“…Thus, intertidal reefs may respond to and recover from anthropogenic stressors such as oil spills very differently than do subtidal reefs. This difference may explain why Dietl & Durham (2016) found that the average size of living and dead oysters did not differ between oiled and unoiled intertidal reefs. Yet, Powers et al (2017b, this Theme Section) found that impacts of oiling resulted in the reduction of oyster habitat by up to 77% in areas that experienced heavy oiling.…”
