SeaQuest is the latest iteration in a series of Fermilab experiments designed to probe nucleon structure using the Drell-Yan process. The most recent ancestor of SeaQuest, E866/NuSea, used the Drell-Yan process to provide the most comprehensive observations of the light-quark flavor asymmetry to date, which suggested signicant non-pertubative effects in the nucleon sea. Other measurements concerning cold nuclear matter, J/ production, and Drell-Yan angular distributions were conducted as well. SeaQuest aims to complement the flagship NuSea measurement by probing higher seaquark momenta at a lower center-of-mass energy and higher intensity. A summary of the light-quark flavor asymmetry measurement status will be reported as well as the status of various parallel analyses, one of which could have implications for the Boer-Mulders initial state TMD.
