and shallow underwater terrain (bathymetry). The Navigator uses LiDAR (light detection and ranging) technology with a green laser to penetrate water surfaces and generate accurate 3D ...

This new study highlights the enhanced accuracy of optical satellite-derived bathymetric datasets in a shallow, low-wave-energy coastal environment by identifying the best combination of input ...

The rift valley may fill with fresh water and become a lake. As the rift opens, ocean water may invade. The shallow waters of the rift valley can be ideal environments for limestones to form. Here is ...
