This semester I've taken an ocean chemistry module! Largely because its 50% course work... anyway.
This is the salinity machine we have here and basically we put in the water samples on the left and run them through 1,000,000 times it seems and eventually get the salinity reading for each of our samples, crazy exciting right?! I'm not joking when i say we spent two hours with this machine and didn't get entirely accurate readings. But the applications of this are very useful because salinity varies with depth and different organism can survive at different salinity levels, with fresh water being an influence on it. So once you put the sample in a current is run through it which the machine uses to calculate the temperature which we can then calculate the salinity from. note the high tech way that we get the water out of the machine before we put it in a new sample (the orange tube and bin).
