We treat the baryon as a composite system made out of a 'core' of three quarks (as in the standard quark model) surrounded by a 'sea' (of gluons and qq-bar-pairs) which is specified by its total quantum numbers like flavor, spin and color. Specifically, we assume the sea to be a flavor octet with spin 0 but no color. The general wavefunction for spin 1/2 baryons with such a sea component is given and an application to the magnetic moments is considered. Numerical analysis shows that the scalar sea can provide a good fit to the magnetic moment data using experimental errors.
