Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Oceanography
  • Ecosystem

Toshi Nagata mostly deals with Ecology, Environmental chemistry, Dissolved organic carbon, Bacterioplankton and Seawater. The Environmental chemistry study combines topics in areas such as Organic matter, CHN analyzer, Pelagic zone, Bacterivore and Biomass. His biological study deals with issues like Phytoplankton, which deal with fields such as Total organic carbon.

His Dissolved organic carbon research includes themes of Biochemistry and Nutrient. His biological study spans a wide range of topics, including Phylogenetics and Phylogenetic tree. His Seawater study incorporates themes from Protein degradation, Marine bacteriophage, Membrane protein and Microbiology.

His most cited work include:

  • Direct Determination of Carbon and Nitrogen Contents of Natural Bacterial Assemblages in Marine Environments (484 citations)
  • Production mechanisms of dissolved organic matter (345 citations)
  • Assessing the apparent imbalance between geochemical and biochemical indicators of meso- and bathypelagic biological activity: What the @#! is wrong with present calculations of carbon budgets? (182 citations)

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

Oceanography, Ecology, Environmental chemistry, Dissolved organic carbon and Phytoplankton are his primary areas of study. His work in Oceanography covers topics such as Total organic carbon which are related to areas like Carbon cycle. Ecology is represented through his Trophic level, Nutrient, Picoplankton, Plankton and Biogeochemical cycle research.

He has researched Environmental chemistry in several fields, including Organic matter, Epilimnion, Hypolimnion, Seawater and Nitrate. His research in Dissolved organic carbon intersects with topics in δ13C and Respiration. Toshi Nagata interconnects Pelagic zone and Chlorophyll a in the investigation of issues within Phytoplankton.

He most often published in these fields:

  • Oceanography (38.82%)
  • Ecology (35.88%)
  • Environmental chemistry (27.06%)

What were the highlights of his more recent work (between 2016-2021)?

  • Oceanography (38.82%)
  • Isotope analysis (4.12%)
  • Ecology (35.88%)

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

Toshi Nagata mainly investigates Oceanography, Isotope analysis, Ecology, Trophic level and Bay. His Oceanography research is multidisciplinary, relying on both Nitrogen fixation and Diazotroph. His research on Isotope analysis frequently links to adjacent areas such as Biogeochemical cycle.

His Ecology research integrates issues from Phenylalanine and Amino acid nitrogen. His research in Trophic level tackles topics such as δ15N which are related to areas like Surface water. As a member of one scientific family, he mostly works in the field of Bay, focusing on Algal growth and, on occasion, Dissolved organic carbon.

Between 2016 and 2021, his most popular works were:

  • Advances in the application of amino acid nitrogen isotopic analysis in ecological and biogeochemical studies (98 citations)
  • Diazotroph community structure and the role of nitrogen fixation in the nitrogen cycle in the Chukchi Sea (western Arctic Ocean) (35 citations)
  • Heat accumulation on coral reefs mitigated by internal waves (26 citations)

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

  • Ecology
  • Ecosystem
  • Enzyme

Toshi Nagata mostly deals with Oceanography, Ecology, Isotope analysis, Amino acid and Ecosystem. Arctic is the focus of his Oceanography research. Toshi Nagata combines subjects such as Phenylalanine and Amino acid nitrogen with his study of Ecology.

His Isotope analysis study integrates concerns from other disciplines, such as Trophic level, Euphausia, Krill and Foraging. His work carried out in the field of Amino acid brings together such families of science as Fraction, Column chromatography, Contamination, High-performance liquid chromatography and Diethyl ether. His Ecosystem study combines topics in areas such as Reef, Coral reef, Coral bleaching and Internal wave.
