Additional Information

  • Depth data from Kurt Fisher database
    • Cherrington, 1969: 2.98 km
  • Mare area of 35,475 km^2 according to measurements by Jim Whitford-Stark.
  • Compton, a farside crater located "behind" Mare Humboldtianum, is rather difficult to observe during favourable libration. However, the central peak of Compton is quite an easy target because of the pronounced shape of it (relatively steep slopes). See LPOD Peaking over the Limb and discussions.
  • One of three basins with crustal thicknesses less than 5 km. The Crust of the Moon as Seen by Grail by Wieczorek et al (2013).
  • Atypical exposure of olivine-rich material - from mantle? - surrounding this basin. Yamamoto et al (2010) Nat. Geosci. 3, 533.

Nomenclature

  • The IAU feature name (Latin for "Humboldt Sea") honors Friedrich Wilhelm Heinrich Alexander von Humboldt(September 14, 1769 – May 6, 1859), a German naturalist and explorer. Humboldt's quantitative work on botanical geography was foundational to the field of biogeography. He was one of the first to propose that the lands bordering the Atlantic were once joined (South America and Africa in particular). Late in life, in his five-volume work Cosmos, he attempted to unify the various branches involved in knowledge of the world. The scope of this remarkable work may be briefly described as the representation of the unity amid the complexity of nature. In it the large and vague ideals of the 18th are sought to be combined with the exact scientific requirements of the 19th century. And, in spite of inevitable shortcomings, the attempt was in an eminent degree successful.
  • The impact basin is named after the mare.
  • Once called Pappi by Langrenus, Palus Amadoca by Hevelius, and Zoroaster by Riccioli. Madler's name Mare Humboldtianum is still used and officially recognized by the IAU (see also: Ewen A. Whitaker's Mapping and Naming the Moon).
  • The inner and outer rings of Mare Humboldtianum are unofficially called the Andes Mountains (outer ring) and the Bishop Mountains (inner ring). Source: Charles Wood.
