His main research concerns Climatology, Dendrochronology, Dendroclimatology, Paleoclimatology and Ecology. Samuli Helama specializes in Climatology, namely North Atlantic oscillation. Samuli Helama has included themes like El Niño Southern Oscillation, Anomaly and Precipitation, Megadrought in his North Atlantic oscillation study.
His study in Dendrochronology is interdisciplinary in nature, drawing from both Proxy, Statistics, Time series, Woody plant and Chronology. The study incorporates disciplines such as Fagaceae, Scots pine, Frost, Subfossil and Quercus robur in addition to Dendroclimatology. His Paleoclimatology study is related to the wider topic of Climate change.
Samuli Helama spends much of his time researching Dendrochronology, Climatology, Climate change, Physical geography and Chronology. Samuli Helama focuses mostly in the field of Dendrochronology, narrowing it down to matters related to Scots pine and, in some cases, Forestry. His studies in Climatology integrate themes in fields like Paleoclimatology and Holocene.
He has researched Paleoclimatology in several fields, including Series and Subarctic climate. His research in the fields of Climatic warming overlaps with other disciplines such as Context, Environmental health, Cause of death and Suicide prevention. His Chronology study combines topics in areas such as Statistics, Sclerochronology and Precipitation.
Samuli Helama focuses on Dendrochronology, Physical geography, Climatology, Paleoclimatology and Ecology. He studies Dendrochronology, focusing on Dendroclimatology in particular. Samuli Helama combines subjects such as Spring, Chronology, Phenology and Subfossil with his study of Physical geography.
His work carried out in the field of Climatology brings together such families of science as Little ice age and Arctic. Paleoclimatology is a subfield of Oceanography that Samuli Helama tackles. His Climate change study combines topics from a wide range of disciplines, such as Carbon sequestration and Agriculture.
His primary areas of study are Dendrochronology, Climatology, Paleoclimatology, Physical geography and Climate change. His biological study spans a wide range of topics, including Ecology and Atmospheric sciences. His work on Proxy, North Atlantic oscillation and Northern Hemisphere as part of general Climatology study is frequently linked to Research council, therefore connecting diverse disciplines of science.
His Paleoclimatology research incorporates elements of Subarctic climate and Holocene. His work is dedicated to discovering how Physical geography, Subfossil are connected with Interglacial, Volcano, Chronology and Isotopes of carbon and other disciplines. His research in Climate change intersects with topics in Agriculture and Taiga.
