Thomas H. Johengen focuses on Ecology, Zebra mussel, Dreissena, Eutrophication and Microcystis. His Phytoplankton, Plankton and Zooplankton investigations are all subjects of Ecology research. Thomas H. Johengen has included themes like Trophic level and Biomass in his Phytoplankton study.
His research investigates the link between Plankton and topics such as Benthic zone that cross with problems in Water column. His research in Zebra mussel focuses on subjects like Bay, which are connected to Nutrient and Water quality. His Bloom research is multidisciplinary, relying on both Climate change, Spring bloom, Algal bloom and Water supply.
Thomas H. Johengen mainly investigates Ecology, Oceanography, Statement, Hydrology and Phytoplankton. His study in the field of Zooplankton, Plankton and Trophic level is also linked to topics like Dreissena. His Hydrology research includes themes of Dissolved organic carbon, Shore and Eutrophication.
He has researched Eutrophication in several fields, including Bloom and Algal bloom. His Phytoplankton study combines topics from a wide range of disciplines, such as Diatom and Ecosystem. His work investigates the relationship between Nutrient and topics such as Zebra mussel that intersect with problems in Environmental chemistry.
His primary areas of investigation include Algal bloom, Eutrophication, Remote sensing, Microcystis and Bloom. The study incorporates disciplines such as Biomass, Sampling, Climatology and Water quality in addition to Algal bloom. His biological study spans a wide range of topics, including Hydrology and Chlorophyll.
He works mostly in the field of Remote sensing, limiting it down to topics relating to Water column and, in certain cases, Lidar, Plankton and Benthic zone, as a part of the same area of interest. As part of his studies on Microcystis, Thomas H. Johengen often connects relevant areas like Phycobilisome. His Bloom research integrates issues from Overwintering and Agronomy.
His scientific interests lie mostly in Algal bloom, Microcystis, Remote sensing, Water column and Ecosystem. His studies deal with areas such as Environmental technology and Environmental planning as well as Algal bloom. Combining a variety of fields, including Microcystis, Bloom, Chlorophyll, Animal science and Eutrophication, are what the author presents in his essays.
The concepts of his Remote sensing study are interwoven with issues in Biomass, Wind speed, Atmospheric sciences and Growing season. His research integrates issues of Lidar, Stratification and Plankton in his study of Water column. Ecosystem is a subfield of Ecology that Thomas H. Johengen investigates.
