  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
$q\bar{q}$-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.
