Advances in the latter half of the past decade have uncovered the prevalence of ultra-diffuse galaxies (UDGs) across all environments comma from cluster cores to the field. These galaxies are challenging to fit into our standard picture of galaxy formation and are thus of great interest to both observers and theorists. Owing to the observational challenges presented by such diffuse stellar distributions comma one of the most effective means of constraining the properties of UDGs is their globular cluster (GC) systems. HST has already played a vital role in characterizing the richness and form of the GC populations of UDGs comma finding that some host extremely rich and anomalously bright GC systems comma as well as providing some of the first estimates of the halo masses of UDGs. However comma to date all such studies have focused on UDGs in dense environments. Here we propose a snapshot imaging program with WFC3-UVIS to make the first measurements of the GC systems of bona fide field UDGs. Although more challenging to identify and confirm than UDGs in clusters and groups comma field UDGs are thought to constitute a major fraction of the overall UDG population and likely represent the original formation pathway for many UDGs that subsequently fell into groups. Comparison of the GC systems of these two populations is an ideal means to test whether they have physically similar origins comma but as yet we know little of the GCs in field UDGs. The proposed observations would also provide a key reference sample for numerous other works investigating the potential formation mechanisms of UDGs and other low surface brightness galaxies comma which in turn may hold clues to some of the small scale problems of LCDM.
