Terry Isson


Terry Isson at the University of Waikato, for the paper:

(2020) Evolution of the Global Carbon Cycle and Climate Regulation on Earth. Global Biogeochemical Cycles. 34(2), e2018GB006061.

Isson, T.T., N.J. Planavsky, L. Coogan, E. Stewart, J.J. Ague, E.W. Bolton, S. Zhang, N.R. McKenzie, L.R. Kump. (2020)

This outstanding publication is a comprehensive review article of the global long-term carbon cycle, invited as part of AGU's centennial papers on 'Grand Challenges in the Earth and space sciences'. The article pieces together decades worth of research on the global carbon cycle and its evolution. In particular, this article details the evolution of the long-term carbon cycle budget; silicate weathering; reverse weathering; stabilizing feedbacks within the global carbon cycle; the role of land plants in weathering and carbon sequestration; best estimates of solid Earth degassing fluxes; carbon sinks; sources of acid for terrestrial weathering; groundwater alkalinity fluxes; marine weathering; and our most up to date views on the links between the oxygen – iron – sulphur and carbon cycles and how these cycles have co-evolved to give rise to a habitable planet.

This outstanding publication presents the highest resolution carbon isotope records obtained to date for high-latitudes in the Southern Hemisphere across ‘Ocean Anoxic Event 2’ (OAE 2), which occurred ~94 million years ago. This study provides important insights into the causal mechanisms leading to extreme oxygen deprivation in the oceans.

Werner Friedrich Giggenbach was born in Augsberg in Germany in 1937.  Following study in Germany and the US he joined the Chemistry Division of DSIR in 1968.  Apart from two years spent in Vienna at the International Atomic Energy Agency, Werner remained there and later at IGNS for the remainder of his career.

Werner was an outstanding scientist who became an internationally recognised leader in the field of fluid and related fluid/rock interactions in active geothermal and volcanic systems.  He published about 100 refereed papers and chapters in books, of which half are single author contributions in leading geochemistry journals and conference proceedings.

The Geological Society of New Zealand awarded him the prestigious ‘MacKay Hammer’, the New Zealand Institute of Chemistry elected him as a Fellow, as did the US Society of Economic Geologists.  He was also an editor or associate editor of several prestigious international journals.  His final honour, election to Fellow of the Royal Society of New Zealand, was awarded posthumously in 1997.
