This problem can be solved by pluggin in the given coefficients where indcated and then substituting the Temperature and salinity for each given location.

Below I have written out the function so all you have to do is plug in the temperature and salinity, and then copy and past the expression into google. Google calendar should give the answer.

8.00969062 x 10^(-2)+5.88194023 x 10^(-2)(T)+7.97018644 x 10^(-1)(S)+-8.11465413 x 10^(-3)(T^2)+-3.25310441 x 10^(-3)(S)(T)+1.31710842 x 10^(-4)(S^2)+4.76600414 x 10^(-5)(T^3)+3.89187483 x 10^(-5)(S)(T^2)+2.87971530 x 10^(-6)(S^2)(T)+-6.11831499 x 10^(-8)(S^3)

EXAMPLE: the density of the Gulf stream is given below.

8.00969062 x 10^(-2)+5.88194023 x 10^(-2)(27.94)+7.97018644 x 10^(-1)(35.89)-8.11465413 x 10^(-3)(27.94^2)-3.25310441 x 10^(-3)(35.89)(27.94)+1.31710842 x 10^(-4)(35.89^2)+4.76600414 x 10^(-5)(27.94^3)+3.89187483 x 10^(-5)(35.89)(27.94^2)+2.87971530 x 10^(-6)(35.89^2)(27.94)-6.11831499 x 10^(-8)(35.89^3)

**=23.1321390637**σ

ANOTHER RESOURCE

Below is a water density calculator, but it deviates by few kg/m^3 because it also takes into account pressure. If you choose to use this tool, in order to show your answer in σ you will need to subtract 1,000 from the answer.
