Description of Research
|
Summary Statement of Research Interests
|
|
Learning about bacteria's ability to promote the absorption of the greenhouse gas may shed light on how the oceans can mitigate the effects of pollution. That's partially why Capone researches the role and importance of marine bacteria in major biogeochemical cycles particularly those of nitrogen and carbon, as well as the response of these populations to, and interactions with, various environmental perturbations. Professor Capone is currently studying the importance of nitrogen fixation in the biogeochemistry of the oceans and the major groups of organisms involved in this process. He is also involved in other studies including experimental manipulation of nutrient dynamics in coral reefs systems, the examination of South Pole snows for active populations of bacteria, and analyses of microbial processes in mangrove ecosystems.

Detailed Statement of Research Interests

Douglas G. Capone’s research focuses on the role and importance of marine microbes in major biogeochemical cycles, particularly those of nitrogen and carbon, both from the perspective of the fundamental ecology of these ecosystems and the physical, chemical and biotic factors controlling these pathways in the environment. Capone has studied diverse systems including the tropical open ocean, coral reefs, mangroves, temperate estuaries, groundwater aquifers and Antarctic snows. He has participated in over 30 major oceanographic expeditions to the tropical Atlantic, Caribbean and Pacific Oceans including to the Great Barrier Reef, and has served as the chief scientist on over 10 of these missions. He has also conducted research at remote field stations in the Caribbean, Great Barrier Reef, McMurdo and South Pole Stations of the US Polar Program.
His laboratory has taken advantage of diverse approaches and technologies (e.g. of physiology, biochemistry, molecular biology, geochemistry and remote sensing). He has published over 150 peer-reviewed articles in scientific journals including Science and Nature. Professor Capone’s research has been supported by NSF, NASA, NOAA, EPA and USGS (among others). In 1999, he received and led two major NSF grants targeting Biocomplexity in the Environment. For these two programs, he organized multi-national teams composed of biological, chemical, geochemical and physical oceanographers, atmospheric chemists and modelers. He collaborates with researchers in diverse fields and countries (e.g. Australia, France, Germany).
Professor Capone is a leading expert on the marine N cycle. He is called upon frequently to provide definitive overviews on the subject. For example, he recently participated and gave synthesis papers at international workshops in England and India. He produced a still highly regarded edited volume on the marine nitrogen cycle (Nitrogen in the Marine Environment, 1983, Academic Press) and has just completed the updated second edition, now in press, as lead Editor.
Capone has had a particularly major impact in raising awareness of nitrogen fixation as a key biogeochemical process in several marine ecosystems. At the outset of his career, he documented the quantitative importance of nitrogen fixation in tropical seagrass ecosystems. More recently, he has focused on open ocean systems and organisms such as the cyanobacterium Trichodesmium, ubiquitous through the tropical ocean, and a substantial source of fixed nitrogen.His work has revealed how nitrogen fixation may be a major determinant of the capacity of the oligotrophic tropical oceans to take up atmospheric carbon dioxide.
