We present recent data on the production and suppression of quarkonia in proton-nucleus at collisions at RHIC. In particular the latest J/ψ suppression in d+Au collisions at is shown from PHENIX and ϒ data from both PHENIX and STAR is presented. These data are confronted with two standard calculations from the literature. The first assumes a factorization of the initial partonic hard scattering from the interaction of the quarkonia pre-cursor with the nucleons while traversing the target. The second calculation leverages a coherence argument to calculate very forward quarkonia production. Finally, we discuss the recent attempt by the PHENIX collaboration to test the geometric dependence on the integrated longitudinal density using this data.
