“…Generally, coral Ba/Ca records upwelling or riverine sedimentation in the coastal environment (Alibert et al, 2003; Lea et al, 1989); however, WFGB is not close enough to a river source or upwelling that would influence coral Ba/Ca. However, the GoM is home to extensive ocean drilling operations that use barite (BaSO 4 ) as drilling muds and has many offshore oil platforms (Figure 1a) that discharge production waters that contain barite into the gulf (Bleiwas and Miller, 2015). The US barite production and consumption can be used as a proxy for barite input to the oceans (Kelly and Matos, 2014) since >90% of barite produced in the US are used for offshore oil drilling (Bleiwas and Miller, 2015) and the GoM is the primary oil field for the US.…”

Barite production and consumption peaks in 1981 with a sharp decline afterward with falling oil prices and coral Ba/Ca captures this peak in 1983 with a three-year delay due to barite production stockpiles taking time to be shipped to the offshore drilling platforms before being used as drilling mud (Weerabaddana et al, 2021).…”

The proposed Anthropocene Global Boundary Stratotype Section and Point (GSSP) candidate site of West Flower Garden Bank (27.8762°N, 93.8147°W) is an open ocean location in the Gulf of Mexico with a submerged coral reef and few direct human impacts. Corals contain highly accurate and precise (<±1 year) internal chronologies, similar to tree rings, and their exoskeletons are formed of aragonite and can be preserved in the rock record. Here we present results from a large Siderastrea siderea coral (core 05WFGB3; 1755–2005 CE) sampled with annual and monthly resolutions that show clear markers of global and regional human impacts. Atmospheric nuclear bomb testing by-products (14C, 239+240Pu) have clear increases in this coral starting in 1957 for 14C and the first increase in 1956 for 239+240Pu (potential bases for the Anthropocene GSSP). Coral δ13C declined especially after 1956 consistent with the Suess Effect resulting from the burning of fossil fuels. Coral skeletal δ15N starts to increase in 1963 corresponding with the increase in agricultural fertilizers. Coral Hg concentrations (1933–1980) loosely track fluctuations in industrial pollution and coral Ba/Ca increases from 1965–1983 when offshore oil operations expand after 1947. Coral temperature proxies contain the 20th-century global warming trend whereas coral growth declines during this interval.

The petroleum industry generates a range of wastes which is often are disposed in soil close to the well location, negatively affecting soil and water quality. The objective of this study was to evaluate the solubility and map the spatial variability of barium in a potentially contaminated area. The study area consisted of a petroleum well-drilling waste disposal site located in the municipality of Mato Rico-PR. A large georeferenced sampling grid was organized. Soil samples were collected at depths of 30, 60, 90, and 120 cm for determination of the "pseudo-total" concentrations and geochemical fractionation of barium. The barium concentrations showed spatial dependence, which permitted the use of geostatistical interpolators. Regarding depth, the depth of 0-30 cm showed the largest contaminated area; however, higher concentrations of barium were found at the depth of 60-90 cm. The results of geochemical fractionation showed that the analyzed samples contained percentages higher than 99% in the non-labile fraction (residual). These results indicate clearly that the barium was in a condition of low solubility, even for samples that had the highest concentrations, presenting low-environmental risk.
