Overview

What is she best known for?

The fields of study she is best known for:

  • Ecology
  • Carbon dioxide
  • Organic chemistry

Katherine H. Freeman mostly deals with Paleontology, Isotopes of carbon, Ecology, Total organic carbon and Geochemistry. Her Paleontology research incorporates themes from Foraminifera, Oceanography and Carbon dioxide in Earth's atmosphere. Her studies deal with areas such as Environmental chemistry, Biogeochemical cycle and Plankton as well as Isotopes of carbon.

Her Environmental chemistry research is multidisciplinary, relying on both Fractionation and Water column. Her research integrates issues of Organic matter, Earth science, Biomass and Carbon, δ13C in her study of Total organic carbon. Katherine H. Freeman interconnects Phytane, Carbonate and Oil shale in the investigation of issues within Geochemistry.

Her most cited work include:

  • Marked Decline in Atmospheric Carbon Dioxide Concentrations During the Paleogene (684 citations)
  • Compound-specific isotopic analyses: a novel tool for reconstruction of ancient biogeochemical processes. (674 citations)
  • Molecular Paleohydrology: Interpreting the Hydrogen-Isotopic Composition of Lipid Biomarkers from Photosynthesizing Organisms (531 citations)

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

Her main research concerns Paleontology, Ecology, Environmental chemistry, Isotopes of carbon and Geochemistry. Her work on Late Miocene expands to the thematically related Ecology. Her Environmental chemistry study incorporates themes from Fractionation and Water column.

The study incorporates disciplines such as δ13C, Carbon dioxide, Oceanography and Carbon cycle in addition to Isotopes of carbon. Her Geochemistry research includes themes of Structural basin and Carbonate. The various areas that she examines in her Total organic carbon study include Organic matter and Earth science.

She most often published in these fields:

  • Paleontology (16.95%)
  • Ecology (15.25%)
  • Environmental chemistry (15.25%)

What were the highlights of her more recent work (between 2017-2021)?

  • Geochemistry (12.71%)
  • Sedimentary rock (8.47%)
  • Olduvai Gorge (6.36%)

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

Geochemistry, Sedimentary rock, Olduvai Gorge, Paleontology and Environmental chemistry are her primary areas of study. Her research combines Carbonate and Geochemistry. Her Paleontology research includes elements of Canopy and Impact crater.

Her Environmental chemistry research is multidisciplinary, incorporating elements of Soil water and Dolomite. Her Structural basin research also works with subjects such as

  • Phytoplankton which intersects with area such as Ecosystem,
  • Coring together with Isotopes of carbon. Katherine H. Freeman combines subjects such as Organic matter and Soil carbon with her study of Total organic carbon.

Between 2017 and 2021, her most popular works were:

  • Viable cyanobacteria in the deep continental subsurface. (54 citations)
  • Soil organic carbon stability in forests: Distinct effects of tree species identity and traits (34 citations)
  • The First Day of the Cenozoic (31 citations)

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

  • Ecology
  • Carbon dioxide
  • Organic chemistry

The scientist’s investigation covers issues in Sedimentary rock, Geochemistry, Sediment, Paleontology and Ecology. Her Sedimentary rock research is multidisciplinary, incorporating perspectives in Pleistocene, Outcrop, Carbonate, Calcite and Olduvai Gorge. Her work deals with themes such as Structural basin, Total organic carbon and Section, which intersect with Geochemistry.

Her Sediment research integrates issues from Environmental chemistry, Seafloor spreading and Biodegradation. Her studies link Scientific drilling with Paleontology. Much of her study explores Ecology relationship to Late Miocene.
