The scientist’s investigation covers issues in Mineralogy, Oceanography, Particulates, Seawater and River mouth. He focuses mostly in the field of Mineralogy, narrowing it down to matters related to Hydrothermal vent and, in some cases, Sedimentation, Ridge and Analytical chemistry. His study in Oceanography is interdisciplinary in nature, drawing from both Biota and Mid-Atlantic Ridge.
His work in Particulates covers topics such as Hydrology which are related to areas like Environmental chemistry, Tonne and Diagenesis. His Seawater research includes themes of Basalt and Mid-ocean ridge. His research investigates the link between River mouth and topics such as Continental shelf that cross with problems in Total organic carbon, Hydrography, Terrigenous sediment and Organic matter.
John H. Trefry mainly investigates Oceanography, Environmental chemistry, Seawater, Mineralogy and Particulates. As part of his studies on Oceanography, John H. Trefry frequently links adjacent subjects like Organic matter. The various areas that he examines in his Environmental chemistry study include Atomic absorption spectroscopy, Pollution and Trace metal.
The concepts of his Seawater study are interwoven with issues in Environmental engineering and Produced water. His research in Mineralogy focuses on subjects like Ridge, which are connected to Mid-ocean ridge. His Particulates research is multidisciplinary, incorporating elements of Hydrology, Geochemistry, Settling and Water column.
John H. Trefry spends much of his time researching Oceanography, Environmental chemistry, Estuary, Arctic and Ecology. He has included themes like Phytoplankton and Diagenesis in his Oceanography study. His work deals with themes such as Nutrient flux, Subtropics and Dredging, which intersect with Environmental chemistry.
His biological study deals with issues like Organic matter, which deal with fields such as Salinity. His Arctic study combines topics in areas such as Submarine pipeline, Granulometry, Marine ecosystem, Fishery and Shoal. His Coastal plain, Climate change and Global warming study, which is part of a larger body of work in Ecology, is frequently linked to Coastal flood, bridging the gap between disciplines.
Oceanography, Shoal, Fishery, Arctic and Marine ecosystem are his primary areas of study. In the subject of general Oceanography, his work in Antarctic sea ice is often linked to Coastal flood, thereby combining diverse domains of study. The Antarctic sea ice study combines topics in areas such as Ice shelf, Drift ice and Sea ice thickness.
Arctic ice pack and Cryosphere are the areas that his Sea ice thickness study falls under. His Coastal flood study spans across into areas like Sea level, Deglaciation, Global warming, Climate change and Continental shelf. His studies in Sea level integrate themes in fields like Coastal plain and Ecology.
