We treat the baryon as a composite system made out of a {open_quote}{open_quote}core{close_quote}{close_quote} of three quarks (as in the standard quark model) surrounded by a {open_quote}{open_quote}sea{close_quote}{close_quote} (of gluons and {ital 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 {ital using} {ital experimental} {ital errors}. {copyright} {ital 1996 American Institute of Physics.}
