2015 - Keith Moore

Keith Moore (University of California at Irvine) has been a key member of the Biogeochemistry Working Group for over 10 years. In the early 2000's he, Scott Doney and Keith Lindsay designed and assembled the first version of the biogeochemistry component of the ocean model. Keith Moore had worked on several of the parameterizations that were incorporated into this first version of the component. He has been involved in all further developments of the component, and has written many papers using this component, some of which are listed below.

Three of these papers show results from the 20th century run using the CESM1(BGC) version. In this run, the ocean did not take up enough carbon dioxide from the atmosphere. Over the last year or more, Keith Moore undertook to refine many of the coefficients in the biogeochemistry module so that the ocean would take up more CO2. These coefficient values are now in the CESM(BGC) version that is being used for a second 20th century run, which will be started in the near future.
