Precise acoustic seafloor positioning with joint estimation of sound speed field structure using a layered sound speed gradient model

Abstract The accuracy of GNSS-Acoustic (GNSS-A) seafloor positioning is much affected by spatiotemporal variability in the ocean Sound Speed Field (SSF). The conventional depth-invariant horizontal sound speed gradient models represent the water-column sound speed structure using a single effective...
