Model results are compiled in the file "SOIREEmodel.xls"

This file includes 7 sheets:

Var.out: state variables time series (outside the patch)

Var.in: state variables time series (inside the patch)

Act.out: activities (biogenic elements fluxes) time series (outside the patch)

Act.in: activities (biogenic elements fluxes) time series (inside the patch)

BudgetC: integrated carbon budget

pCO2: surface pCO2 time series

Forcing: hydro-meteorological forcings




Comments:

Sheet 1 (Var.out):


60 days (10/02/1999 to 10/04/1999) time series of the state variables values, averaged daily

and over the upper mixed layer (UML)

See state variables list in Table 1 below.

Diatoms and autotrophic nanoflagellates chlorophyll a (columns AH, AI) are estimated on the

basis of the functional and structural metabolites concentration (state variables DAF and NFF),

using a conversion factor of 0.5 mg chla / mmol C



Sheet 2 (Var.in):

see Sheet 1



Sheet 3 (Act.out):

activities time series (outside the patch)

60 days (10/02/1999 to 10/04/1999) time series of the activities (biogenic elements fluxes)

values, integrated over the upper mixed layer (UML) and daily averaged.

See activities list in Table 2 below.



Sheet 4 (Act.in):

see Sheet 3



Sheet 5 (BudgetC):

Carbon budget of the Upper Mixed Layer, calculated over 13 days (site occupation of SOIREE) and

60 days since the initial iron release (inside and outside the fertilized patch)



Sheet 6 (pCO2):

Time series of daily averaged surface water pCO2 (in situ temperature, 100% wet) (inside and

outside the fertilized patch)



Sheet 7 (Forcing):

Time series of daily averaged wind velocity (m s-1), sea surface temperature (°C), and

mixed layer depth (m).
