Pick $2$ different locations. These $2$ locations should not be close to each other geographically.

As it is highlighted with a red circle in Figure $1,$ indicate the coordinates for each of your location. $(10$ p$)$ Indicate the locations you picked in your Matlab script $($simply by using $\%$xxxxx$)$ and in your report. Homeworks without the location information will not be evaluated.

Make sure that your variables are set up as; Temperature, Salinity and Density $($as shown in Fig. $1).$ Don't forget to click "redraw" to refresh the page so that the data you will get in the next step shall be updated as well.

Click on "Data in current view" and then click on "Get Table" button. Save this data file.

Write a MATLAB script that reads the data files. Calculate the density of seawater at a given Salinity, Temperature and Pressure by using the "Equation of Sea State". At this point, ignore the Density column in the data file you saved in step $4.(50$ p$)$

After calculating the density, plot Temperature $(C)$ vs Depth $($m$)$; Salinity $($p$.$s$.$u$)$ vs Depth $(m)$ and Density $(\frac{g}{c}{m}^3)$ vs Depth $(m).$ Remember $1\frac{d}{b}ar=1m.$ Look all your plots for the two locations you picked. What are the main differences between these two locations by means of salinity, density and temperature? Make comments. $(30$ p$)$

Remember the Density column you ignored $($step $5)$ in the data file. Now plot Density $(\frac{g}{c}{m}^3)$ vs Depth $(m)$ by using this data file. Compare this plot with your calculated

results. Check if your calculations are correct. $(10$ p$)$ If not, try to find out your mistake and redo.
