SoKa Project 2020 → For better bathymetry grids

Understanding the dynamics and circulation of oceans is quite a challenge while having tremendous impact on global and local environment. There exists multiple ways to approach it: from buoy releases to numerical modeling. However, whatever the method chosen, the knowledge of the bathymetry (seafloor elevation) is a keystone of the process.
