The density \[\rho \] of water of bulk modulus B at a depth y in the ocean is related to the density at surface \[{{\rho }_{0}}\] by the relation

\[\rho ={{\rho }_{0}}\left[ 1+\frac{Beta }{{{\rho }_{0}}hgy} \right]\]

\[\rho ={{\rho }_{0}}\left[ 1-\frac{{{\rho }_{0}}gy}{B} \right]\]

\[\rho ={{\rho }_{0}}\left[ 1+\frac{{{\rho }_{0}}gy}{B} \right]\]

\[\rho ={{\rho }_{0}}\left[ 1-\frac{B}{{{\rho }_{0}}gy} \right]\]
