On the use of a deep pressure gradient constraint for estimating the steady state ocean circulation from hydrographic data

Estimating unobserved quantities such as velocitiesand transports indirectly from temperature and salinity measurements is oneof the best studied problems in physical oceanography. It is illposed. The ill posedness is traditionally removed by adding priorinformation such as a level of no motion or a...
