“…These results alone cannot discount a shipwreck from WWII (Figure ) as it is possible that a refinery equipped with a delayed coker could have produced a product similar to the mystery oil. More than 500 shipwrecks from WWII are known to exist in the South Atlantic Ocean, and it increasingly presents itself as a potential polluter of the oceans. , In this sense, rubber bales from the SS Rio Grande shipwreck (Figure ) arrived along the northeast of the Brazilian coast in 2018 . The release of this cargo was attributed to the natural corrosion of the shipwreck hull or unauthorized salvage of its metal cargo, which may also have released the oil.…”

The release of this cargo was attributed to the natural corrosion of the shipwreck hull or unauthorized salvage of its metal cargo, which may also have released the oil. However, more investigation is needed as the appearance of ancient raw material and the possibility of oil produced in the 1940s and 1950s emerge as strong evidence of the contribution of shipwrecks.…”

viscous oil residues appeared along the Brazilian coast spanning 11 states and more than 3,000 km of tropical shoreline. Forensic results published to date indicate that the majority of oil samples collected share a common origin, yet the exact source of the mystery oil has yet to be conclusively determined. The proposed sources include illegal discharges from vessels traversing near, within, or downstream of Brazilian waters, leaking offshore platforms, natural seeps, and historic shipwrecks. To constrain the potential sources of oil and provide additional insights into the composition of the oil, we analyzed samples collected from the Cearástate coastal zone in 2019 with a broad suite of geochemical tools and approaches. These approaches included bulk elemental analyses and state-ofthe-art analytical platforms including comprehensive two-dimensional gas chromatography (GC × GC), gas chromatography with triple-quadrupole mass spectrometry, and Fourier transform ion cyclotron resonance mass spectrometry. Based on bulk and molecular features, field samples collected from northeast Brazil share the same source as other 2019 mystery oil samples collected over ∼2400 km to the south. A shared source across the Brazilian coast points to an input location east of Brazil within the southern branch of the South Equatorial Current, allowing transport both north and south of the bifurcation. The relative abundance and composition of diagnostic markers were consistent with the published analyses of Venezuelan petroleum. The composition of the field samples is consistent with the blending of, at least, two different petroleum products, a common practice to produce an "on spec" product such as a fuel oil used to power an underway vessel. The two components appear to be the residuum from atmospheric distillation and a thermally altered, aromatics-rich, nondistilled material. To the best of our knowledge, no samples from potential sources are available for a direct comparison to field samples. Hence, these results play a supporting role in determining the source, and benefit efforts to understand short-and long-term weathering and recovery.

“…3). The SEC current system has three different branches (north, central and south) that transport debris [22] and pollutants [23] present in the tropical area between Brazil and Africa toward the Brazilian shelf. Those materials can then be transported northward by the NUBC and NBC and/or southward by the BC, along the Brazilian continental slope from where they can enter the shelf due to eddies, meanders, upwelling events, and other cross-shore circulation mechanisms [23].…”

With four decades of WWII underwater archaeology publications, the time is nigh to create a comprehensive bibliography and conduct an analysis of trends within the growing subfield. This paper presents a decade-by-decade analysis of academic publications accessible through a number of search engines and databases. It analyzes the papers through the categories of author gender, heritage type, region, and focus. Finally, it provides the data set by which this analysis was accomplished in a comprehensive bibliography.
