Mare Humorum, or the Sea of moisture which has a size of 389 km, is surrounded on the outside of  many large craters and on the inside area do not have many craters outstanding.
Some craters are listed in these pictures, as Gassendi crater that is the most important eye-catching ring by its shape, with a stretch of 110 km (seen in the first 3 shots), and has only 1.9 miles deep.
When viewed through spectroscopic analysis, crater Gassendi presents a "behavior" very different from any other lunar crater. Studies conducted in high-resolution infrared light indicated the presence of extrusive volcanic material (ie volcanic material flowing to the surface and then crystallizes), limited to the south Gassendi crater floor, which is adjacent to Mare Humorum.

Mersenius (84 km), although smaller in size than Gassendi, it is deeper, with a depth of 2.3 km, and is in an area with many more depressions. It can be seen in the first 3 shots, and in the picture below to be better located. Mersenius lies west of Mare Humorum.
Doppelmayer (64 km), is a remnant of a lunar crater that is located south-west edge of the Mare Humorum. South-east of Doppelmayer, is another flooded crater named Lee (41 kmand Vitello (42 km).
Doppelmayer's edge is nearly round, but is eroded. The most intact is the south-west, while in the Northeast is going down under the sea of Humorum, leaving only a slight increase in the surface. The interior has been flooded by lava, leaving a large ridge high in the center.
