George A. Jackson mostly deals with Oceanography, Photic zone, Water column, Atmospheric sciences and Ecology. His studies examine the connections between Oceanography and genetics, as well as such issues in Phytoplankton, with regards to Sargasso sea. His studies in Photic zone integrate themes in fields like Inorganic chemistry, Settling and Mineralogy. The concepts of his Water column study are interwoven with issues in Deep sea, Field, Organic matter and Physical oceanography. His study in Atmospheric sciences is interdisciplinary in nature, drawing from both Pacific ocean and Meteorology. His research in Nutrient tackles topics such as Upwelling which are related to areas like Environmental chemistry.
