How far can you smell in water?

Answer 1

YOU can not smell anything under water, because you will drown silly! But fish and other organisms that live in the water can taste(using the same type of receptors as smell) things in the water like micro particles of other plants, animals, and nutrients. I would guess that if humans could smell under water, we would smell the clay/ground, the fish, and other waste.

Answer 2

Well it all depends on the density of the water, ya see mountain water is twice as dense as spring water which is 1 tenth less dense than sea water. Now we now that you also have involve the density of all the animals in the water. now if you sniff sea water than you get an overpoweringly salty feel in your nose this means that their is a whale aproximatly 10 metres above sea level. now if you decide to smell the mountain spring water well here comes the technical stuff: autotrophic lateral clorinessis is actually the piocuries per square potato with the atomic terrafirmic relationship between apricots and apples divided by pinapple times mango but it all comes down to depend on how much water you suck in your nostral into your longitudetitle piograph.
