The fleeting existence of quark-antiquark pairs within the proton
(or neutron) is a well-established consequence of quantum
chromodyamics. It is, however, still a largely open question as to
whether this sea of quark-antiquark pairs, which contains
contributions from all the quark flavors (up, down, strange, etc.), has
any effect on the properties of the nucleon. In particular,
the contribution of the sea to the magnetic moment and the charge
distribution of the proton has been a topic of considerable interest.
A series of experiments, using parity-violating electron scattering
to probe of the sea, have been conducted at various labs in recent
years. The results of these experiments, in particular the
G0 and HAPPEX experiments at Jefferson Lab, will be reviewed, and
possible interpretations of the results will be presented.
