Overview

What is he best known for?

The fields of study he is best known for:

  • Ecology
  • Oceanography
  • Climate change

Oceanography, Paleoclimatology, Holocene, Climatology and Arid are his primary areas of study. The study incorporates disciplines such as Sedimentary rock, Northern Hemisphere and Chronology in addition to Oceanography. The concepts of his Paleoclimatology study are interwoven with issues in Paleontology, Quaternary, Pleistocene and Physical geography.

His Holocene research includes elements of Glacial period, Monsoon, Ecosystem model and Terrestrial ecosystem. He combines subjects such as Orbital forcing, Tropics, Global warming, Deglaciation and Intertropical Convergence Zone with his study of Climatology. Thomas C. Johnson interconnects Tropical climate and Period in the investigation of issues within Arid.

His most cited work include:

  • Late pleistocene desiccation of Lake Victoria and rapid evolution of cichlid fishes (464 citations)
  • East African megadroughts between 135 and 75 thousand years ago and bearing on early-modern human origins (321 citations)
  • History and timing of human impact on Lake Victoria, East Africa. (275 citations)

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

Thomas C. Johnson mainly focuses on Oceanography, Paleontology, Holocene, Sediment and Paleoclimatology. Thomas C. Johnson has included themes like Arid and Structural basin in his Oceanography study. As a part of the same scientific study, Thomas C. Johnson usually deals with the Paleontology, concentrating on Geomorphology and frequently concerns with Shore.

Intertropical Convergence Zone is closely connected to Climatology in his research, which is encompassed under the umbrella topic of Holocene. The various areas that he examines in his Paleoclimatology study include Tropical climate, Physical geography and Paleolimnology. His work deals with themes such as Ecology and Deglaciation, which intersect with Pleistocene.

He most often published in these fields:

  • Oceanography (41.27%)
  • Paleontology (21.16%)
  • Holocene (23.28%)

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

  • Oceanography (41.27%)
  • Paleontology (21.16%)
  • Holocene (23.28%)

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

His primary scientific interests are in Oceanography, Paleontology, Holocene, Physical geography and Sediment. His research in Oceanography is mostly focused on Paleoclimatology. He studied Paleontology and Human evolution that intersect with Deep sea.

His Holocene research includes themes of Quaternary sediments, Radiocarbon dating, Volcanism, Geochemistry and Carbon cycle. His study on Physical geography also encompasses disciplines like

  • Period together with Hydrology and Structural basin,
  • Sea surface temperature that connect with fields like Pleistocene. His study in Sediment is interdisciplinary in nature, drawing from both Seismology, Paleomagnetism and Series.

Between 2015 and 2021, his most popular works were:

  • The Limnology, Climatology And Paleoclimatology of the East African Lakes (274 citations)
  • Anthropogenic climate change has altered primary productivity in Lake Superior (52 citations)
  • A progressively wetter climate in southern East Africa over the past 1.3 million years (50 citations)

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

  • Ecology
  • Oceanography
  • Climate change

Thomas C. Johnson focuses on Physical geography, Oceanography, Holocene, Paleoclimatology and Limnology. His Physical geography study combines topics in areas such as Ice age, Pleistocene, Orbital forcing, Sea surface temperature and Arid. His Oceanography research is multidisciplinary, incorporating perspectives in Terrigenous sediment and Interglacial.

His work carried out in the field of Holocene brings together such families of science as Seismology, Structural basin, Sediment and Series. His biological study spans a wide range of topics, including Sedimentary rock, Climatology, Productivity and Global warming. Thomas C. Johnson has researched Limnology in several fields, including Ecosystem and Carbon cycle.
