Whole Ocean Fine Resolution Carbon Management Simulations Systems
Abstract
Building from the Los Alamos suite of advanced grid global ocean circulation models, we are developing a system for fine mode simulation of the full spectrum of carbon sequestration strategies (varieties of fertilization and deep CO2 injection). Detailed nitrogen, iron, sulfur ecodynamics is being supplemented with carbon geocycling and functional group (diatom) segregation in an eddy permitting version of the Parallel Ocean Program (global average 1/5 degree lat/long). We have performed multiple iron enrichments in patches as small as 100 kilometers on a side. Results will be shown for various HNLC zones, in the form of evolving iron uptake and phytoplankton bloom distributions. Less complete ecodynamics will be used initially to drive carbon and related tracer penetration experiments in fine mode isopycnal and hybrid z-density OGCM's. Surface sourced tracers have been tracked entering the deep sea over the century time scale in the MICOM code. We are now designing carbon cycle routines for the HYCOM and HYPOP hybrid programs.
