* The idea __here__ is to have some variables describing the variation in ''' recruitment '''

{{{
#!html
<h3 style="color: #00FF00">The regional seas</h3>
}}} 

 * The sea_cd => this one is obvious, and will describe varying recruitments into the Baltic, the Mediterranean, North sea, unfortunately sea_cd is repeated and probably needs grouping with other variable [[BR]]

This will create a new column in ccm21.seoutlets
{{{
#!sql
ALTER TABLE ccm21.seaoutlets ADD COLUMN area_cd character varying(3);
UPDATE ccm21.seaoutlets set area_cd= system_cd||sea_cd;
}}}
Now that sounds much better :[[BR]]
