CNPDIA-package {CNPDIA}R Documentation

An early diagenetic model for C, N, P and O2 cycle in marine sediments.

Description

CNPDIA is a 1-D model of Carbon, nitrogen, phosphorus and oxygen diagenesis in a marine sediment. It is based on the OMEXDIA model, extended with simple P dynamics and with microphytobenthos dynamics.

The model describes twelve state variables, in 100 layers:

Concentrations of liquids and solids are expressed in [nmol/cm3 liquid] and [nmol/cm3 solid] respectively. See Soetaert et al., 1996 for further details of the original OMEXDIA model.

MPBDIA extends the CNPDIA model with microphytobenthos dynamics. In addition to the CNPDIA state variables it also describes the following state variables:

The models are implemented in fortran and linked to R.
