In October 2015, NOAA selected Dr. Rik Wanninkhof to become a Senior Scientist, the highest attainable level for federal research scientists within NOAA. Rik is an internationally recognized authority on air-sea gas transfer with years of experience studying the effects of atmospheric carbon dioxide on the ocean. Senior Technical Scientist positions are held by individuals who achieve national and/or international distinction in their field through their high-level research. In recognition of his exceptional scientific contributions, he was elected a Fellow of the American Geophysical Union in 2009.
Rik began his career at AOML in 1991 as an oceanographer with the Ocean Chemistry and Ecosystems Division. He has conducted research on the inorganic carbon cycle, focusing on the uptake of anthropogenic carbon dioxide by the oceans and the effects of increasing carbon dioxide levels on ocean biogeochemical cycles and ecology. Much of this research involves decadal sampling of hydrographic sections throughout the global ocean to quantify changes in the storage and transport of carbon dioxide, nutrients, fresh water, and heat. He currently leads AOML’s Ocean Carbon Group, which researches the transport and transformation of carbon in the ocean.
As a principal investigator, Rik’s work stimulated the development of entirely new field techniques for quantifying air-sea gas transfer velocity, as well as multi-investigator, international field experiments to test and apply these methods in different oceanic environments. He co-led the development of the global surface ocean observing system for the partial pressure of carbon dioxide (pCO2) within NOAA, and his Ocean Carbon Group is one of the most important contributors to the global pCO2 databases.
