Additional Information
- Depth data from [/Kurt%20Fisher%20crater%20depths Kurt Fisher database]
- Cherrington, 1969: 1.49 km
- Mare area of 84,500 km^2 according to measurements by Jim Whitford-Stark.
Nomenclature
The IAU feature name means "Sea of Moisture".
- Called Anticaspia (Opposite the Capspian) by Gassendi (who called Mare Crisium Caspia). ([/Whitaker Whitaker]: Mapping and Naming the Moon, p 33).
- The impact basin is named for the mare.
- The western rim of Mare Humorum was once called the Percy mountains by William Radcliff Birt, but the I.A.U. did not accept that name.
- The trio of craterlets at centre of Mare Humorum's basin are nicknamed Mare Humorum's triplet by D.Caes (Doppelmayer J, K, and L).
The abundance of White Spots on the wrinkle ridges of Mare Humorum
To try to find your way on the floor of Mare Humorum is a tricky business, because none of the wrinkle ridges up here have names. Moonobserver Danny Caes decided to include some sort of unofficial nomenclature system (see list below).
Why an additional nomenclature system for wrinkle ridges in Mare Humorum?
The LROC's High-Res NAC close up photographs of Mare Humorum reveal curious chains of White Spots on the uppermost parts of its wrinkle ridges. Each one of these White Spots is composed of a large number of high-albedo boulders and rocks. These small compact fields of "white" boulders and rocks must be quite a strange experience for astronauts who want to explore these odd spots. Another peculiar fact of these boulder-rich fields is their sharp boundaries. An astronaut would cross a flat featureless low-albedo region to enter (abruptly) a "lunar wood" of high-albedo boulders and rocks! One could call these White Spots lunar labyrinths composed of irregular white walls!
Catalog of wrinkle ridges in Mare Humorum
- Dorsum Puiseux D: the pronounced wrinkle ridge at the eastern part of Mare Humorum, with crater Puiseux D about "halfway" on the ridge.
- Puiseux D North: the northern part of Dorsum Puiseux D.
- Puiseux D South: the southern (or southwestern) part of Dorsum Puiseux D (from Puiseux D to Puiseux G).
- Gassendi Southeast: the pronounced wrinkle ridge from Gassendi to Gassendi O.
- Gassendi Southwest: the curved wrinkle ridge southwest of Gassendi.
- Dorsa Kelvin: the arc-shaped system of wrinkle ridges on the eastern part of Mare Humorum, near Promontorium Kelvin.
- Dorsum Doppelmayer J: the wrinkle ridge north-northwest of Doppelmayer J at Mare Humorum's western part.
