  We present Cassini VIMS observations of sun glitter -- wave-induced
reflections from a liquid surface offset from a specular point -- on Kraken
Mare. Sun glitter reveals rough sea surfaces around Kraken Mare, namely the
coasts and narrow straits. The sun glitter observations indicate wave activity
driven by the winds and tidal currents in Kraken Mare during northern summer.
T104 Cassini VIMS observations show three sun glitter features in Bayta Fretum
indicative of variegated wave fields. We cannot uniquely determine one source
for the coastal Bayta waves, but we lean toward the interpretation of surface
winds, because tidal currents should be too weak to generate capillary-gravity
waves in Bayta Fretum. T105 and T110 observations reveal wave fields in the
straits of Seldon Fretum, Lulworth Sinus, and Tunu Sinus that likely originate
from the constriction of tidal currents. Coastlines of Bermoothes and Hufaidh
Insulae adjoin rough sea surfaces, suggesting a complex interplay of
wind-roughened seas and localized tidal currents. Bermoothes and Hufaidh
Insulae may share characteristics of either the Torres Strait off Australia or
the Aland region of Finland, summarized as an island-dense strait with shallow
bathymetry that hosts complex surface circulation patterns. Hufaidh Insulae
could host seafloor bedforms formed by tidal currents with an abundant sediment
supply, similar to the Torres Strait. The coastlines of Hufaidh and Bermoothes
Insulae likely host ria or flooded coastal inlets, suggesting the Insulae may
be local peaks of primordial crust isolated by an episode of sea-level rise or
tectonic uplift.
