Overview

What is he best known for?

The fields of study he is best known for:

  • Carbon dioxide
  • Ecology
  • Oceanography

Urumu Tsunogai spends much of his time researching Hydrothermal circulation, Mineralogy, Oceanography, Environmental chemistry and Geochemistry. His work focuses on many connections between Hydrothermal circulation and other disciplines, such as Seafloor spreading, that overlap with his field of interest in Trough, Sedimentary rock, Fault scarp and Authigenic. His Mineralogy research includes elements of Deep sea and SULFATE ION.

The concepts of his Oceanography study are interwoven with issues in Nitrous oxide, Isotopes of nitrogen and Oxygen-18. His work carried out in the field of Environmental chemistry brings together such families of science as Biochemistry, Methanogen, Anaerobic oxidation of methane, Methane and Archaea. His Mantle, Basalt and Marcasite study, which is part of a larger body of work in Geochemistry, is frequently linked to Sulfide, bridging the gap between disciplines.

His most cited work include:

  • Cell proliferation at 122°C and isotopically heavy CH4 production by a hyperthermophilic methanogen under high-pressure cultivation (455 citations)
  • Geochemical and microbiological evidence for a hydrogen-based, hyperthermophilic subsurface lithoautotrophic microbial ecosystem (HyperSLiME) beneath an active deep-sea hydrothermal field (241 citations)
  • Precursory Chemical Changes in Ground Water: Kobe Earthquake, Japan (210 citations)

What are the main themes of his work throughout his whole career to date?

His scientific interests lie mostly in Geochemistry, Environmental chemistry, Methane, Oceanography and Mineralogy. His Geochemistry research is multidisciplinary, relying on both Sediment, Seafloor spreading and Hydrothermal circulation. His research investigates the link between Environmental chemistry and topics such as Nitrate that cross with problems in Hydrology and Nitrification.

His Methane research includes themes of Water column and Isotopes of carbon. His studies in Oceanography integrate themes in fields like Isotopes of nitrogen and δ13C. As part of one scientific family, Urumu Tsunogai deals mainly with the area of Mineralogy, narrowing it down to issues related to the Seawater, and often Sedimentary rock.

He most often published in these fields:

  • Geochemistry (31.85%)
  • Environmental chemistry (22.96%)
  • Methane (19.63%)

What were the highlights of his more recent work (between 2015-2021)?

  • Geochemistry (31.85%)
  • Environmental chemistry (22.96%)
  • Nitrate (11.48%)

In recent papers he was focusing on the following fields of study:

Urumu Tsunogai mainly focuses on Geochemistry, Environmental chemistry, Nitrate, Volcano and Methane. His research in Geochemistry intersects with topics in Hydrothermal circulation, Submarine and Aquifer. His Environmental chemistry research is multidisciplinary, incorporating elements of Seasonality, STREAMS, Nitrogen cycle, Isotopes of oxygen and Trophic state index.

Urumu Tsunogai combines subjects such as Mineralogy, Water vapor and Mantle with his study of Volcano. His Methane research is multidisciplinary, incorporating perspectives in Isotopes of carbon, Water column, Seafloor spreading, Seawater and Nitrite reductase. His Seawater study introduces a deeper knowledge of Oceanography.

Between 2015 and 2021, his most popular works were:

  • Deep-biosphere methane production stimulated by geofluids in the Nankai accretionary complex (41 citations)
  • Ecological and genomic profiling of anaerobic methane-oxidizing archaea in a deep granitic environment. (28 citations)
  • Accurate and precise quantification of atmospheric nitrate in streams draining land of various uses by using triple oxygen isotopes as tracers (18 citations)

In his most recent research, the most cited papers focused on:

  • Carbon dioxide
  • Ecology
  • Oceanography

Geochemistry, Hydrothermal circulation, Environmental chemistry, Nitrate and Volcano are his primary areas of study. His Geochemistry research incorporates elements of Carbon cycle, Aquifer, Groundwater and Methane. His Methane study incorporates themes from Structural basin, Nitrite reductase, Archaea and Continental crust.

His study in Hydrothermal circulation is interdisciplinary in nature, drawing from both Water column, Impact crater, Trough and Magma. His Environmental chemistry research includes elements of Isotopes of oxygen, Seasonality and Trophic state index. His Isotopes of oxygen research integrates issues from Paleoclimatology, Foraminifera, Globigerina bulloides, Plankton and Seawater.
