GNSS-Acoustic Observations of Seafloor Crustal Deformation Using a Wave Glider
Frontiers in Earth Science, 2021 Crustal deformation of the seafloor is difficult to observe solely using global navigation satellite system (GNSS). The GNSS-acoustic (GNSS-A) technique was developed to observe seafloor crustal deformation, and it has produced a steady series of ...
