I need help with this homework. I'm having trouble figuring this out. Can anyone please help me? Please and Thank you

Start with the initial instruction,

By reading off the charts and using the T-S diagram on Page 3, fill in the following information

Look at pg3. Charts show depth, temperature and salinity. All you need is to transfer the units.

Yes but I don't get though is that I need all of the information ranging from 20-100. I only see up to 30 on page 3.

Sorry, page 2. Goes from 0 to 140 meters. Then following directions, use Pg3. To determine density.

IMPORTANT: Notice that the values on the density curves or lines are incomplete. They should read 1.030 g/cm3 or 1.025g/cm3 or 1025 g/dm3 and so forth! See figure7.26. Hint a cubic meter of pure water has a mass of 1000kg

Is this the page 2 graph? Cannot tell from the attachment, but appears to guide you to the correct data inputs.

So I use the graph on page 2 for the 1st 2 sections then Graph 3 for Density?

Only you can decide if the graph is the figure referenced in your instructions. Is it?

See figure7.26.

Seems your answers are there.
