The Huygens surface science package sound speed measurements and the methane content of Titan's atmosphere

, 2008
The Huygens probe descended through Titan's atmosphere in January 2005. On board was the Surface Science Package (SSP), a set of nine sensors, which included a speed-of-sound sensor.

Reconstruction of the underwater sound speed field of mesoscale eddies in typical sea areas based on the physically-constrained deep learning model

Applied Ocean Research
As a widespread dynamical phenomenon in the world’s oceans, mesoscale eddies significantly alter the temperature and salinity of water masses, leading to differences in the sound speed profile (SSP) within the eddies compared to the surrounding seawater.

A TOA/AOA Underwater Acoustic Positioning System Based on the Equivalent Sound Speed

, 2018
High-precision underwater positioning must eliminate the influence of refraction artefacts. Since a Time Of Arrival - Global Navigation Satellite System Intelligent Buoys (TOA-GIB) system does not measure incident beam angles, common refraction ...

Hierarchical clustering of historic sound speed profiles

, 2008
Categorizing historical sound speed profiles stems from the desire to map spatial and temporal variability. Sound speed variability correlates with environmental phenomena and is an indicator of changes in sonar performance.

Precise GNSS-acoustic seafloor positioning with sound speed from global ocean analysis

Satellite Navigation
The Global Navigation Satellite System–Acoustic (GNSS-A) combined positioning technique extends geodetic networks into the seafloor. Currently, GNSS-A can achieve static seafloor positioning accuracy at centimeter level. However, in practical operations,
