CHAPTER 5 . Particulate Organic Matter Composition and Fluxes in the Sea
Fig. 5.11. Depth profiles of
total POC flux (solid line) and
protected organic carbon flux
(dashed line) are illustrated in a
schematic representation. Protected flux is assumed to be
proportional to ballast flux. The
hatched area between the two
curves is the flux of unprotected POC. Neither protected
nor unprotected POC flux are
measured directly; their
magnitudes are inferred by
fitting measured values to a model
(Armstrong et al. 2002)

tive models of organic matter flux that are useful over broad regions of the ocean and
over seasonal and interannual time scales.
