Overview

What is he best known for?

The fields of study he is best known for:

  • Oceanography
  • Ecology
  • Carbon dioxide

His scientific interests lie mostly in Oceanography, Nitrate, Glacial period, Environmental chemistry and Phytoplankton. His Oceanography research incorporates themes from Ice age and Sediment. His work carried out in the field of Nitrate brings together such families of science as Thermocline, Seawater, Diatom, Denitrification and Isotopes of oxygen.

His Denitrification research is multidisciplinary, relying on both Isotopes of nitrogen and Nitrogen cycle. His study on Huronian glaciation is often connected to Wisconsin glaciation as part of broader study in Glacial period. His Phytoplankton research is multidisciplinary, incorporating elements of Abundance and Surface water.

His most cited work include:

  • Southward Migration of the Intertropical Convergence Zone Through the Holocene (1573 citations)
  • A Bacterial Method for the Nitrogen Isotopic Analysis of Nitrate in Seawater and Freshwater (1148 citations)
  • Measurement of the Oxygen Isotopic Composition of Nitrate in Seawater and Freshwater Using the Denitrifier Method (986 citations)

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

His primary areas of study are Oceanography, Nitrate, Environmental chemistry, Glacial period and Isotopes of nitrogen. His Oceanography study combines topics in areas such as Ice age, Phytoplankton, Nitrogen cycle and Interglacial. His Ice age research is multidisciplinary, incorporating perspectives in Foraminifera, Sea ice and Iron fertilization.

In his research, Sediment is intimately related to Denitrification, which falls under the overarching field of Nitrate. His work deals with themes such as Organic matter and Sediment core, which intersect with Environmental chemistry. His Glacial period study integrates concerns from other disciplines, such as Diatom, Stratification and Holocene.

He most often published in these fields:

  • Oceanography (58.97%)
  • Nitrate (30.45%)
  • Environmental chemistry (18.91%)

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

  • Oceanography (58.97%)
  • Nitrate (30.45%)
  • Isotopes of nitrogen (13.78%)

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

Daniel M. Sigman focuses on Oceanography, Nitrate, Isotopes of nitrogen, Environmental chemistry and Foraminifera. His study explores the link between Oceanography and topics such as Ice age that cross with problems in Deglaciation. The study incorporates disciplines such as Seawater and Phytoplankton, Nutrient in addition to Nitrate.

He interconnects Diatom, Denitrification, Nitrogen fixation and Ocean gyre in the investigation of issues within Isotopes of nitrogen. Daniel M. Sigman has researched Environmental chemistry in several fields, including Organic matter and Nitrogen cycle. Halocline is closely connected to Carbon dioxide in his research, which is encompassed under the umbrella topic of Glacial period.

Between 2016 and 2021, his most popular works were:

  • Nitrogen Isotopes in the Ocean (163 citations)
  • The GEOTRACES Intermediate Data Product 2017 (138 citations)
  • 21st-century rise in anthropogenic nitrogen deposition on a remote coral reef (48 citations)

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

  • Oceanography
  • Ecology
  • Carbon dioxide

The scientist’s investigation covers issues in Oceanography, Nitrate, Phytoplankton, Isotopes of nitrogen and Water column. His Oceanography study typically links adjacent topics like Organic matter. In his study, Sediment trap is inextricably linked to Seawater, which falls within the broad field of Nitrate.

His Phytoplankton research focuses on Upwelling and how it connects with Zonal and meridional, Dominance, World Ocean Circulation Experiment, Nitrogen fixation and Ecosystem. He has included themes like Environmental chemistry and Denitrification in his Isotopes of nitrogen study. Daniel M. Sigman studied Holocene and Iron fertilization that intersect with Ice age.
