Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Bathymetry can be measured using methods other than sonar?

Yes. Multiple studies demonstrate that bathymetry can be effectively measured using non-sonar methods, including satellite altimetry, airborne gravity data, and multispectral satellite imagery.

The analysis

The claim states that bathymetry can be measured using methods other than sonar. Papers [0], [1], [2], [3], [6], and [11] all explicitly discuss and demonstrate non-sonar methods for measuring underwater depth and seafloor topography (such as satellite altimetry, airborne gravity, and satellite-derived bathymetry from optical imagery). There are no papers refuting the claim, and the evidence entirely supports it.
