respiration. General representation of the Arctic ecosystem is shown in Figs. 6.4
and 6.5 .
Let us designate the Arctic Basin aquatory as are

latitude and longitude, respectively. Spatial inhomogeneity of the Arctic Basin
model is provided for by the set of cells

Ω ={( ˆ , ʻ )}, where ˆ and ʻ

D T CO 2 with latitude and longitude steps of

ʔˆ and ʔʻ , respectively. These cells are the basic spatial structure of Ω for the

realization of the computer algorithms. The cells Ω ij are heterogeneous as to their

parameters and functioning. There are a set of cells which are adjacent to the river
mouths (

Ω R ) and to the ports ( Ω P ), bordering on the land Xð , in the Bering Strait
