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 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.
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.
