Mangrove sediment blue carbon estimates

Carbon accumulation in coastal wetlands is normally assessed by extracting a sediment core and estimating its carbon content and bulk density. Because carbon content and bulk density are functionally related, the latter can be estimated gravimetrically from a section of the core or, alternatively, from the carbon content in the sample using the Mixing Model equation from soil science. We analyzed the effect that the choice of corer and the method used to estimate bulk density could have on the final estimates of carbon storage in the sediments.
The choice of corer did not have much influence on the final estimates of carbon density; the main factor in selecting a corer is the operational difficulties that each corer may have in different types of sediments.
Because of the multiplication of errors in a product of two variables subject to random sampling error, when using gravimetric estimates of bulk density, the dispersion of the data points in the estimation of total carbon density ris..., ,
