Methane route of hydrocarbons formation at very high pressure and high temperature. by V. G. Kutcherov, A. Yu. Kolesnikov

“…Results of experimental investigations of synthesis of hydrocarbon systems at high pressure and different mechanisms of synthesis are discussed. experimental results presented in this paper confirm the possibility of synthesis of hydrocarbon at mantle conditions from methane. these results can be accepted as support for the theory of the abyssal abiotic petroleum origin.…”

Topographic enhancement of vertical turbulent mixing in the Southern Ocean by A. Mashayek, R. Ferrari, S. Merrifield, J. R. Ledwell, L. St Laurent, A. Naveira Garabato

“…Turbulent mixing next to rough topographic features is believed to be key in the closure of the abyssal ocean circulation. Here, using Southern Ocean data, the authors show that mixing hotspots trap fluid and mix it for long periods, explaining the global impact of relatively few mixing hotspots.…”

CO2 Transport in Deep Waters Off Wilkes Land by Taro Takahashi, David W. Chipman

“…These waters spill over the shelf edge and, during their descent, mix with components of Circumpolar Deep Water (CPDW) to form the Antarctic Bottom Water (AABW) that fills the major abyssal basins of the world ocean. This process constitutes an important pathway between the atmosphere and the abyssal ocean for long-term storage of CO2. …”

Quantifying assemblage turnover and species contributions at ecologic boundaries. by Lee-Ann C Hayek, Brent Wilson

“…With these measures we examine benthonic foraminiferal assemblages to assess glacial/interglacial contrasts at abyssal depths. Our results indicate that these measures, ATI and CoBI, have potential as sequence stratigraphic tools in abyssal depth deposits. …”

Dynamical pathways of Antarctic Bottom Water in the Atlantic by Stephens, J, Marshall, D

“…This is also consistent with an analytical result derived by extending the Parsons mechanism to an abyssal layer overlying arbitrary bathymetry. The authors suggest that the results provide a more convincing zero-order picture than the Stommel-Arons model for the circulation of AABW and perhaps for abyssal water masses in general.…”

On the glacial and interglacial thermohaline circulation and the associated transports of heat and freshwater by M. Ballarotta, S. Falahat, L. Brodeau, K. Döös

“…From these diagnostics, we found that the LGM Conveyor Belt circulation is driven by an enhanced salinity contrast between the Atlantic and the Pacific basin. The LGM abyssal circulation lifts and makes the Conveyor Belt cell deviate from the abyssal region, resulting in a ventilated upper layer above a deep stagnant layer, and an Atlantic circulation more isolated from the Pacific. …”

Antarctic Bottom Water Jets Flowing from the Vema Channel by Eugene G. Morozov, Oleg A. Zuev, Dmitry I. Frey, Viktor A. Krechik

“…Properties of the abyssal current of Antarctic Bottom Water (AABW) from the Vema Channel are studied based on temperature, salinity, and velocity profiler (CTD/LADCP) data. …”

Diversities and interactions of phages and bacteria in deep-sea sediments as revealed by metagenomics by Xumei Sun, Haibo Jiang, Siyuan Zhang

“…The relative abundance of phages in these ecosystems was higher than in other three abyssal ecosystems. The low phage/host ratios obtained from host prediction were different from shallow ecosystems and indicated the prevalence of prophages, suggesting the complexity of phage–bacteria interactions in abyssal ecosystems. …”

Spatial distribution of benthic macrofauna in the Central Arctic Ocean. by Andrey Vedenin, Manuela Gusky, Andrey Gebruk, Antonina Kremenetskaia, Elena Rybakova, Antje Boetius

“…Permanent sea-ice cover and low primary productivity in the mostly ice-covered Central Arctic ocean basins result in significantly lower biomass and density of macrobenthos in the abyssal plains compared to the continental slopes. …”

Types, characteristics and implication for hydrocarbon exploration of the Middle Miocene deep-water sediments in Beikang Basin, southern South China Sea by Zhen-yu Lei, Li Zhang, Ming Su, Shuai-bing Luo, Xing Qian, Bo-da Zhang

“…A well-developed source-reservoir-cap assemblage was composed by deep rift-stage source rocks, deep-water clastic reservoirs of the Middle Miocene, and bathyal-abyssal deep-water fine-grained sediments after the Middle Miocene, implying a good potential for hydrocarbon exploration.©2019 China Geology Editorial Office.…”

Marine geophysical studies of the southern margins of the Iberian Peninsula by Chowdhury, S, Suman Chowdhury

What processes drive the ocean heat transport? by Ferrari, Raffaele, Ferreira, David

“…In this study we use long simulations of an ocean model to investigate whether the heat transport is carried primarily by wind-driven gyres or whether it is dominated by deep circulations associated with abyssal mixing and high latitude convection. The heat transport is computed as a function of temperature classes. …”

Noble gas tracers of ventilation during deep-water formation in the Weddell Sea by Nicholson, D, Khatiwala, S, Heimbach, P

Distal transport of dissolved hydrothermal iron in the deep South Pacific Ocean by Jenkins, William J., Fitzsimmons, Jessica Nicole, Boyle, Edward A

“…Until recently, hydrothermal vents were not considered to be an important source to the marine dissolved Fe (dFe) inventory because hydrothermal Fe was believed to precipitate quantitatively near the vent site. Based on recent abyssal dFe enrichments near hydrothermal vents, however, the leaky vent hypothesis [Toner BM, et al. (2012) Oceanography 25(1):209–212] argues that some hydrothermal Fe persists in the dissolved phase and contributes a significant flux of dFe to the global ocean. …”

Mineralogy, Geochemistry and Tectonic Setting of the Raobazhai Ultramafic Complex, North Dabie by Fangchao Yan, Qing Liu, Quanlin Hou, Miao He

“…Both mineral and whole-rock geochemistry showed typical abyssal peridotite affinity. Due to the presence of water-bearing minerals, the Sr, Ba, and U were enriched, and the Nb, Zr, and Hf were depleted, which can be attributed to the strong metasomatism of the boninitic melting/fluid in the fore-arc domain. …”
