Rigaweb: Gulf of Riga autumn planktonic food web

Description Usage Format Author(s) References See Also Examples


Carbon flux matrix of the Gulf of Riga planktonic food web in autumn as reconstructed by inverse modelling by Donali et al. (1999).

The Gulf of Riga is a highly eutrophic system in the Baltic Sea.

The foodweb comprises 7 functional compartments:

  • picoautotrophs (P1)

  • non-picoautotrophs (P2)

  • bacteria (B)

  • heterotrophic nanoflagellates (N)

  • zooplankton (Z)

  • detritus, including virus (D)

  • dissolved organic carbon (DOC)

and two external compartments:

  • CO2

  • Sedimentation

These compartments are connected with 26 flows.

Units of the flows are mg C/m3/day.




matrix with flow values, where element ij denotes flow from compartment i to j

rownames and columnames are the components.
