InVEST Blue Carbon Model USGS
Model Specifics Inputs Outputs Biophysical Biophysical Carbon storage (Mg C/ha) Carbon sequestration (Mg C/ha/yr) Economic value of carbon storage and sequestration Maps of nearshore marine veg. Amt. stored in 4 carbon ‘pools’ Aboveground biomass Belowground biomass Sediments Dead organic matter Rate of carbon accumulation in sediments for each veg. type Market or social value of seq. carbon Annual rate of change and a discount rate Economic (optional) Economic (optional)
