Dowden served as a scientist with the Radiophysics Division of the
CSIRO, as a scientist on
Macquarie Island, and as a scientist with the Ionic Prediction Service in

University of Tasmania and
Otago University (1966-1998), where he was appointed Beverly Professor of Physics. In the course of his career, Dowden made numerous research journeys to both the
Arctic and
Antarctic regions. The research from Dowden was extensive. Areas of research included
electromagnetic theory and detection techniques, the polarity and longitude of the dipole axis of
Jupiter, very low frequency emissions, the dynamic spectral shape of
electrons in
electromagnetic radiation, high frequency
ionospheric sounders; very low frequency modulation of the auroral electrojet; detection and interpretation of red
sprites; invention of the dynagraph; and Jupiter polarmetrics. Dowden authored or co-authored some 119 scientific monographs. ==Recognition==
