“…Despite the limitations of N:C, its potential value as a tool for biomonitoring pollution events has been recognized in field and mesocosm studies (Marcotte & Coull 1974, Fricke et al 1981, Amjad & Gray 1983, Gee et al 1985, Sandulli & Giudici 1989, Kennicutt et al 1996, Sutherland et al 2007, Wang et al 2011, Riera et al 2012). More recently, and arguably more relevant to the present study, the N:C has worked well to classify impacts of drilling activities in the Gulf of Mexico (Montagna & Harper 1996).…”

“…This survey design was used because transects extending in radial patterns from the source of contamination and the statistical analysis of such designs have been used successfully in prior studies (e.g. Kennicutt et al 1996). Sediment samples were collected using an Ocean Scientific International multicorer, which takes 12 simultaneous cores from a single deployment at each station.…”

The Deepwater Horizon (DWH) blowout and oil spill of 2010 released an estimated 4.9 million barrels of oil into the Gulf of Mexico. Spill-related contaminants that sank to the seafloor pose risks to benthic fauna living within bottom substrates that are unable to avoid exposure due to their relatively sedentary existence. Metazoan meiofauna are abundant and diverse members of deep-sea soft-sediment communities and play important roles in ecosystem function. We investigated the deep-sea metazoan meiofauna community response to the DWH blowout and oil spill at 66 stations ranging from <1 km to nearly 200 km from the Mississippi Canyon Block 252 wellhead. Metazoan meiofauna abundance, diversity, and the nematode to copepod ratio (N:C) varied significantly across impact zones. Nematode dominance increased significantly with increasing impacts, and N:C spiked near the wellhead. Conversely, major taxonomic diversity and evenness decreased in zones of greater impacts that were in closer proximity to the DWH wellhead. Copepod abundance and the abundance of minor meiofauna taxa decreased where impacts were most severe, and at these severely impacted stations the abundance of ostracods and kinorhynchs was negligible. Increasing abundance and dominance by nematodes with increasing impacts likely represent a balance between organic enrichment and toxicity. Spatial analysis of meiofauna diversity and N:C at 66 stations increased our spatial understanding of the DWH benthic footprint and suggests expanded spatial impacts in areas previously identified as uncertain.

“…In contrast, discharges of drill muds and cuttings during drilling operations are denser than water and often end up deposited on the sea floor close to the platform. The Minerals Management Service (MMS) program-Gulf of Mexico Offshore Operations Monitoring Experiment (GOOMEX), Phase I: Sublethal Response to Contaminant Exposure measured contaminants in sediments at three offshore platforms (Kennicutt 1995). The GOOMEX study sites were located in the northwestern Gulf of Mexico in water depths from 29 to 125 m (95-410 ft) (Figure 4.25).…”

“…The specific criteria used for the selection of control locations must be given for any environmental study (e.g. Kennicutt et al 1996) in addition to full details about the locations used. Our results demonstrate how seemingly appropriate control locations may, in fact, be totally inadequate because of environmental variables that were not considered because there was no prior reason to include them.…”

Recruitment and development of subtidal epibiota were sampled using settlement plates to identlfy appropriate control locations for tests of environmental impacts of estuarine marinas. Sampling was designed to determine how far any effects of marinas may extend and how the position of a location within an estuary may affect the recruitment and development of epibiota. Mannas may have had minor impacts on epibiotic assemblages, but certainly none that extended further than 1.5 km; hence, locations 1.5 km from mannas could potentially serve as controls. Assenlblages at the inner end of a creek were, however, likely to be very different from those at positions closer to the mouth. Thus, for studies of marinas situated at the ends of creeks, control locations would need to be in corresponding positions in adjacent creeks. W~thout information of this kind, impacts may b e either detected erroneously or masked because inappropriate control locations might be used.
