The E906/SeaQuest experiment at Fermilab is studying the distributions of anti-quarks in the nucleon sea with 120 GeV protons interacting on solid and liquid targets. E1039 will extend these measurements using the existing spectrometer with an upgraded polarized proton and deuteron target. The primary goal of E1039 is to study transverse single spin asymmetry in Drell-Yan production to determine the Sivers function in sea quarks up to a Bjorken-x of 0.45. Additionally, E1039 allows for many other interesting opportunities including sea quark transversity measurements where existing data has large uncertainties, exploring possible sensitivity of $\frac{J}{\psi}$ production to the Sivers function, and a parasitic trigger for dimuons with a downstream vertex as predicted in various models of dark photon decay. This presentation will focus on these additional topics which can be explored by E1039.
