What is he best known for?
The fields of study he is best known for:
- Paleontology
- Ecology
- Climate change
John Hellstrom focuses on Stalagmite, Speleothem, Oceanography, Paleontology and Quaternary.
John Hellstrom usually deals with Stalagmite and limits it to topics linked to Sea level and Thermohaline circulation and Marine Isotope Stage 5.
The various areas that John Hellstrom examines in his Speleothem study include Climatology, δ18O and Physical geography.
His work on Oceanography is being expanded to include thematically relevant topics such as Cave.
In the subject of general Paleontology, his work in Pleistocene, Paleomagnetism and Interglacial is often linked to Current practice, thereby combining diverse domains of study.
In his research on the topic of Quaternary, Before Present is strongly related with Paleoclimatology.
His most cited work include:
- Iolite: Freeware for the visualisation and processing of mass spectrometric data (1416 citations)
- Improvements in 230Th dating, 230Th and 234U half-life values, and U–Th isotopic measurements by multi-collector inductively coupled plasma mass spectrometry (657 citations)
- Improved laser ablation U‐Pb zircon geochronology through robust downhole fractionation correction (545 citations)
What are the main themes of his work throughout his whole career to date?
His primary areas of study are Speleothem, Cave, Paleontology, Stalagmite and Physical geography.
As a part of the same scientific study, John Hellstrom usually deals with the Speleothem, concentrating on Climatology and frequently concerns with Climate change.
The study incorporates disciplines such as Karst and Geochemistry in addition to Cave.
His Pleistocene, Quaternary, Chronology, Radiocarbon dating and Radiometric dating investigations are all subjects of Paleontology research.
The concepts of his Stalagmite study are interwoven with issues in Trace element, δ18O, Mineralogy, Calcite and Mediterranean climate.
His studies in Physical geography integrate themes in fields like Younger Dryas, Ice core and Paleoclimatology.
He most often published in these fields:
- Speleothem (41.42%)
- Cave (33.21%)
- Paleontology (28.73%)
What were the highlights of his more recent work (between 2017-2021)?
- Speleothem (41.42%)
- Cave (33.21%)
- Stalagmite (26.12%)
In recent papers he was focusing on the following fields of study:
His primary scientific interests are in Speleothem, Cave, Stalagmite, Physical geography and Glacial period.
His Speleothem research includes themes of East Asian Monsoon, Paleontology, Oceanography, Climate change and Interglacial.
He has included themes like Radiocarbon dating, Geochemistry, Radiometric dating, δ18O and Karst in his Cave study.
His Stalagmite research integrates issues from Mediterranean climate, Trace element, Southwest Australia and Calcite.
His Physical geography study combines topics in areas such as Palynology, Quaternary, Paleoclimatology and Holocene.
His Glacial period research includes elements of Mediterranean sea and Ice sheet.
Between 2017 and 2021, his most popular works were:
- Enhanced climate instability in the North Atlantic and southern Europe during the Last Interglacial. (37 citations)
- U-Pb-dated flowstones restrict South African early hominin record to dry climate phases. (33 citations)
- Contemporaneity of Australopithecus, Paranthropus, and early Homo erectus in South Africa. (30 citations)
