For research purposes, the Madeira Abyssal Plain can be divided into three sub-basins. They are a southern sub-basin, which lies at a water depth of about 5,350 meters (17,550 ft), a central sub-basin which lies at a deeper water depth of about 5,440 meters (17,850 ft), and the northern sub-basin which lies at an intermediate water depth of about 5,420 meters (17,780 ft).
The Port of Manaus measured the Rio Negro river at 12.66 meters on Friday, according to its website, surpassing the previous all-time low recorded last year and still falling rapidly.
However, the path along the river's deepest point is fractal in the same way that the coastline is. Even when detailed maps are available, the length measurement is not always clear. A river may have multiple channels, or anabranches. The length may depend on whether the center or the edge of the river is measured.
