Gain - source flux/total amount of Chi a in the box (i.e. Chi a concentra- 

 tion x box volume) . 



Loss = sink flux/total amount of Chi a in the adjacent MP -3 to Mp -7 box. 

 It was assumed that the loss rate in the MP MP 3 upper layer was the same. 



"Loss = sink flux /total amount of Chi a in the corresponding lower layer 

 box assumed to also apply to the upper layer. 



Growth rate = gain + loss. 



"Doubling time = In 2/growth rate, 



"Sinking rate needed to account 

 depth difference between upper and lower layer of 5.1 m. 



Sinking rate needed to account for a loss rate of 0.69 d over the mean
