|Eponym||Sea of Ingenuity|
Mare Ingenii ("sea of cleverness") is one of the few lunar mare features on the far side of the Moon. The mare sits in the Ingenii basin, which is of the Pre-Nectarian epoch, which lies in turn in the outer part of the older and much larger South Pole–Aitken basin. The mare material located in Ingenii and the surrounding craters is of the Upper Imbrian epoch. The dark circular feature which dominates this mare is the crater Thomson (112 km diameter), with the overflow from Ingenii/Thomson directly to the east. Mare Ingenii is incompletely and thinly covered over much of its expanse with mare lava sheets. The light grey crater to the south of Mare Ingenii is Obruchev.
The mare has swirling patterns of bright material, similar to Reiner Gamma and to patterns within Mare Marginis, which are not associated with topographic or volcanic features. The swirls are associated with magnetic fields.
Mare Ingenii is located at the antipode of the Mare Imbrium impact basin. The furrowed crater walls of the basin (and possibly those of Van de Graaff crater) may have been caused by focused seismic waves resulting from the Imbrium impact.
