  We use 1.4-4.6 micron multi-band photometry of the small inner Uranian and
Neptunian satellites obtained with the James Webb Space Telescope's
near-infrared imager NIRCam to characterize their surface compositions. We find
that the satellites of the ice giants have, to first-order, similar
compositions to one another, with a 3.0 micron absorption feature possibly
associated with an O-H stretch, indicative of water ice or hydrated minerals.
Additionally, the spectrophotometry for the small ice giant satellites matches
spectra of some Neptune Trojans and excited Kuiper belt objects, suggesting
shared properties. Future spectroscopy of these small satellites is necessary
to identify and better constrain their specific surface compositions.
