“…It was necessary to count between 200 and 400 individuals per sample to distinguish 2% significant variability in density and relative abundance between sample intervals (Patterson and Fishbein, 1989). Multiple taxonomic references were used (d 'Orbigny, 1826'Orbigny, , 1839Williamson, 1858;Jones and Parker, 1860;Parker and Jones, 1865;Brady, 1878Brady, , 1879Brady, , 1884Cushman, 1922Cushman, , 1923Cushman, , 1927Stewart and Stewart, 1930;Phleger and Parker, 1951;Parker et al, 1953;Parker, 1954). The number of specimens with visibly fractured tests was counted and reported as the fracture percentage versus the total number of specimens identified as a taphonomical indicator of turbulent flow redistribution (Ash-Mor et al, 2017).…”

Resuspension, Redistribution, and Deposition of Oil-Residues to Offshore Depocenters After the Deepwater Horizon Oil Spill

The focus of this study was to determine the long-term fate of oil-residues from the 2010 Deepwater Horizon (DwH) oil spill due to remobilization, transport, and re-distribution of oil residue contaminated sediments to down-slope depocenters following initial deposition on the seafloor. We characterized hydrocarbon residues, bulk sediment organic matter, ease of resuspension, sedimentology, and accumulation rates to define distribution patterns in a 14,300 km2 area southeast of the DwH wellhead (1,500 to 2,600 m water depth). Oil-residues from the DwH were detected at low concentrations in 62% of the studied sites at specific sediment layers, denoting episodic deposition of oil-residues during 2010–2014 and 2015–2018 periods. DwH oil residues exhibited a spatial distribution pattern that did not correspond with the distribution of the surface oil slick, subsurface plume or original seafloor spatial expression. Three different regions were apparent in the overall study area and distinguished by the episodic nature of sediment accumulation, the ease of sediment resuspension, the timing of oil-residue deposition, carbon content and isotopic composition and foram fracturing extent. These data indicate that resuspension and down-slope redistribution of oil-residues occurred in the years following the DwH event and must be considered in determining the fate of the spilled oil deposited on the seafloor.

The Devonian of the Carnic Alps (Austria) is developed in different facies. The shallow marine facies is up to 1200 m thick. The Feldkogel Limestone of the Polinik Formation, >330 m thick, was dated as Eifelian–Late Devonian. The Feldkogel Limestone at Mount Polinik is developed in a peritidal facies composed of subtidal, intertidal, and supratidal deposits. Subtidal sediments are represented by dark gray Amphipora limestone and intertidal deposits by laminated and partly bioturbated grainstone and packstone, ostracode wackestone to packstone, and locally intercalated intraclast breccias documenting tidal channel fills. Laminated microbial mats (stromatolites) formed in a supratidal depositional environment. Grainstone and packstone contain abundant unilocular parathuramminid foraminifers. This latter group encompasses a diversified assemblage of ivanovellids, parathuramminids, uralinellids, and irregularinoids; some earlandiids are also present. They are dated herein as late Eifelian–early Givetian. These foraminifers provide a more precise systematics of these taxa, which often have not been studied for more than half a century. The taxonomic problems of their assignment to foraminifers, pseudo-foraminifers, calcitarcha, thaumatoporellaceans, volvocaleans, or other algae are also discussed. Several taxa are emendated: Parathuramminida, Parathuramminoidea, Irregularinoidea, Eovolutinidae, Ivanovellidae, Parathuramminidae, Uralinellidae, Ivanovella, Elenella, Neoarchaesphaera, Parathurammina, Bykovaella, Uralinella, and Paracaligella. The new taxa are: Ivanovella reitlingerae n. sp., Elenella polinikensis n. sp., Uralinella sabirovi n. sp., and Radiosphaerella poyarkovi n. sp.

The paper describes Hyperammina micaceus sp. nov., a distinctive new deep-water agglutinated foraminiferan from the Porcupine Abyssal Plain (PAP), northeast Atlantic (4850 m water depth). The new species is tiny (<1 mm long and 20-30 µm wide), with an oval proloculus which merges smoothly into the long, tubular part of the test. The test wall is composed of a single layer of plate-like mineral grains. Hyperammina micaceus occurs in most of the PAP cores collected between 1989 and 2002 and represents up to 4% (in one sample 18%) of the live foraminiferal assemblage in the 0-1 cm layer (>63 µm size fraction). It tends to be more common in samples collected during the late spring and summer (May to September), prior to the spring bloom, than in samples obtained during the autumn (October) and the earlier part of the year (March, April), before the spring bloom. Live specimens are concentrated in the 0-0.5 cm sediment layer but are uncommon in the overlying phytodetrital deposits and virtually absent below 1 cm depth.
