Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Oceanography
  • Ecosystem

His scientific interests lie mostly in Reef, Oceanography, Coral reef, Coral and Ecology. Hajime Kayanne has researched Reef in several fields, including Biomass and Sea level. His Oceanography study combines topics in areas such as Watershed and Tropics.

His Coral reef research is multidisciplinary, incorporating elements of Ecological succession, Groundwater, Carbon cycle, Bedrock and Carbon dioxide. His Coral study combines topics from a wide range of disciplines, such as Western Hemisphere Warm Pool, Sea surface temperature, Climatology, Salinity and Precipitation. His work on Coelenterata, Water column, Cnidaria and Benthic zone as part of his general Ecology study is frequently connected to Biological dispersal, thereby bridging the divide between different branches of science.

His most cited work include:

  • Rapid direct determination of organic carbon and nitrogen in carbonate‐bearing sediments with a Yanaco MT‐5 CHN analyzer (151 citations)
  • Fine-scale mapping of land-derived nitrogen in coral reefs by δ15N in macroalgae (120 citations)
  • Diurnal Changes in the Partial Pressure of Carbon Dioxide in Coral Reef Water (120 citations)

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

Oceanography, Coral reef, Reef, Coral and Atoll are his primary areas of study. His Oceanography study incorporates themes from Paleontology, Radiocarbon dating and Climatology. Within one scientific family, Hajime Kayanne focuses on topics pertaining to Carbonate under Coral reef, and may sometimes address concerns connected to Dissolution, Total organic carbon and Alkalinity.

His studies in Reef integrate themes in fields like Benthic zone and Shore. His Coral study frequently links to adjacent areas such as Sea surface temperature. His Atoll research includes elements of Sediment transport, Sediment, Human settlement, Excavation and Landform.

He most often published in these fields:

  • Oceanography (57.46%)
  • Coral reef (42.54%)
  • Reef (40.30%)

What were the highlights of his more recent work (between 2013-2021)?

  • Coral reef (42.54%)
  • Oceanography (57.46%)
  • Coral (28.36%)

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

His primary areas of study are Coral reef, Oceanography, Coral, Reef and Atoll. His study with Coral reef involves better knowledge in Ecology. A large part of his Oceanography studies is devoted to Sea level.

His Coral study combines topics from a wide range of disciplines, such as Deposition, Sediment transport and Physical geography. As part of the same scientific family, Hajime Kayanne usually focuses on Reef, concentrating on Radiocarbon dating and intersecting with Facies and Sedimentary depositional environment. His Atoll study incorporates themes from Foraminifera, Benthic zone, Intertidal zone, Blue coral and Octocorallia.

Between 2013 and 2021, his most popular works were:

  • Heavy metal contamination of coastal lagoon sediments: Fongafale Islet, Funafuti Atoll, Tuvalu. (73 citations)
  • Net uptake of atmospheric CO2 by coastal submerged aquatic vegetation (59 citations)
  • Validation of degree heating weeks as a coral bleaching index in the northwestern Pacific (47 citations)

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

  • Ecology
  • Oceanography
  • Ecosystem

Hajime Kayanne mostly deals with Oceanography, Reef, Atoll, Coral reef and Benthic zone. Hajime Kayanne combines subjects such as Alkalinity and Total inorganic carbon with his study of Oceanography. Hajime Kayanne has researched Reef in several fields, including Facies, Sedimentary depositional environment and Holocene.

His Atoll research focuses on Intertidal zone and how it relates to Environmental engineering, Contamination, Sediment, Wastewater and Pollution. His study looks at the relationship between Coral reef and fields such as Coral, as well as how they intersect with chemical problems. In general Benthic zone study, his work on Foraminifera often relates to the realm of Population density, thereby connecting several areas of interest.
