The March 15, 2019 Phys.org article A NASA spacecraft may have explored the edges of an early Mars sea in 1997 shows a stylized map of an area on Mars where the Mars Pathfinder landed and uses colors to indicate where bodies of surface water might have once existed.
They are labeled as
- Northern ocean
- Inland Sea
and I noticed they are capitalized. Do these reflect proper nouns and names of possible bodies of water that are recognized by planetary scientists or Martian cartographers (or should I have said Mars cartographers?)? Do these possible bodies of water have other names as well?
