Right: Clementine LIDAR Data, altitude-coded shaded relief from PDS Map-a-Planet remapped to north-up aerial view by LTVT. The dot is the center position and the red circle the main ring position from Chuck Wood's Impact Basin Database. The white circles indicate the positions of the remaining rings according to the Pike & Spudis data.
- AS15-87-11724 is the first one of two spectacular orbital Hasselblads which show Mare Ingenii and its flooded crater Thomson (at Mare Ingenii's northeastern part). Looking south. Note the strange swirl-shaped albedo features in Mare Ingenii's plain. - DannyCaes Dec 27, 2007
- AS15-91-12374 is a curious tan-colored Hasselblad of a small area at Mare Ingenii's northern rim (at 28° South/ 163° East). A reproduction of this Hasselblad was included on page 257 of the splendid article To The Mountains of the Moon by Kenneth F. Weaver (National Geographic, February 1972).

|Certainty of Existence
||Wilhelms Age Group
||165, 315, 450, 660 km
||No; -36 mG gravity anomaly|
- Note: this main ring diameter is from Pike & Spudis (1987). Wilhelms (1987) gives 560 km.
- A major swirl of 10,000 km^2 stretches across Van de Graaff and Mare Ingenii (Hughes and others, 2006).
- Mare area of 36,000 km^2 according to measurements by Jim Whitford-Stark.
- Crater counts yield mare ages of 3.20 and 3.51 b.y. Haruyama, J. and others, 2008.
- The IAU feature name is Latin for "Sea of Cleverness".
- Discovered in Lunik 3 imaging of farside and named in Atlas of the Other Side of the Moon. Approved by the IAU in 1961 (Whitaker, p 232).
- The impact basin is named after the mare.
- Once called "Object A" (see: V.A.Firsoff's The Old Moon and the New; Page 166 and Plate 13b) - DannyCaes Jun 1, 2008
- A distinct rille at the most northern part of Mare Ingenii (south-southeast of Paracelsus M) was unofficially called Vallis Alpha Reed during the hey-days of project Apollo (see: Apollo 15 Flight Journal by David Woods and Frank O'Brien, at 81:15:41 GET in the mission). - DannyCaes Jun 1, 2008
