What is he best known for?
The fields of study he is best known for:
- Paleontology
- Ecology
- Oceanography
His main research concerns Paleontology, Oceanography, Benthic zone, Extinction event and Paleogene.
Many of his research projects under Paleontology are closely connected to Extinction with Extinction, tying the diverse disciplines of science together.
His study on Cretaceous–Paleogene boundary is often connected to Flood basalt, Deccan Traps, Phanerozoic and Mesozoic as part of broader study in Extinction.
His Benthic zone study incorporates themes from Bottom water and Total organic carbon.
Robert P. Speijer studied Paleogene and Stage that intersect with Series, Global climate and Chronostratigraphy.
His research integrates issues of δ18O, Carbonate platform and Fauna in his study of Foraminifera.
His most cited work include:
- The Chicxulub Asteroid Impact and Mass Extinction at the Cretaceous-Paleogene Boundary (792 citations)
- The Paleogene Period (461 citations)
- A benthic foraminiferal record of Paleocene sea level and trophic/redox conditions at Gebel Aweina, Egypt (135 citations)
What are the main themes of his work throughout his whole career to date?
His primary areas of study are Paleontology, Oceanography, Benthic zone, Foraminifera and Paleogene.
In general Paleontology, his work in Cretaceous and Marl is often linked to Extinction event linking many areas of study.
In the field of Oceanography, his study on Sea level, Holocene climatic optimum and Paleoclimatology overlaps with subjects such as Environmental science.
His work deals with themes such as Bay, δ18O, Paleoecology and Upwelling, which intersect with Benthic zone.
The concepts of his Foraminifera study are interwoven with issues in Taphonomy and Isotopes of carbon.
His biological study spans a wide range of topics, including Abundance, Biozone, Cenozoic, Bottom water and Lithology.
He most often published in these fields:
- Paleontology (66.67%)
- Oceanography (47.33%)
- Benthic zone (36.21%)
What were the highlights of his more recent work (between 2015-2021)?
- Oceanography (47.33%)
- Paleontology (66.67%)
- Cretaceous (11.52%)
In recent papers he was focusing on the following fields of study:
His primary areas of investigation include Oceanography, Paleontology, Cretaceous, Benthic zone and Foraminifera.
His work on Environmental change as part of his general Oceanography study is frequently connected to Environmental science, Cretaceous–Paleogene boundary, Dinocyst and Extinction event, thereby bridging the divide between different branches of science.
The Paleogene and Seafloor spreading research Robert P. Speijer does as part of his general Paleontology study is frequently linked to other disciplines of science, such as Event, therefore creating a link between diverse domains of science.
His Cretaceous research includes elements of Phytoplankton, Paleoclimatology, Multi proxy, Anoxic waters and Upwelling.
His Benthic zone research incorporates elements of Sedimentology, δ18O, Structural geology and Carbon cycle.
Robert P. Speijer works mostly in the field of Foraminifera, limiting it down to topics relating to Carbon isotope excursion and, in certain cases, Geochemistry, Stratification and Thermocline, as a part of the same area of interest.
Between 2015 and 2021, his most popular works were:
- The DeepMIP contribution to PMIP4: methodologies for selection, compilation and analysis of latest Paleocene and early Eocene climate proxy data, incorporating version 0.1 of the DeepMIP database (58 citations)
- Latest Cretaceous climatic and environmental change in the South Atlantic region (31 citations)
- Ecological response to collapse of the biological pump following the mass extinction at the Cretaceous–Paleogene boundary (19 citations)
In his most recent research, the most cited papers focused on:
- Paleontology
- Ecology
- Oceanography
His primary scientific interests are in Oceanography, Paleontology, Benthic zone, Cretaceous and Paleoclimatology.
His studies deal with areas such as Early Pleistocene and Northern Hemisphere as well as Oceanography.
His Paleontology research integrates issues from Environmental change and Fauna.
His study in Benthic zone is interdisciplinary in nature, drawing from both Abyssal zone, Paleoecology and Seamount.
Robert P. Speijer focuses mostly in the field of Cretaceous, narrowing it down to matters related to Foraminifera and, in some cases, Upwelling and Diagenesis.
His Seafloor spreading research focuses on subjects like Dominance, which are linked to Paleogene.
