Mercury enters the oceans from:
* Natural sources * industrial processes * Coal burning Once in the ocean it becomes methylated in biological processes in the sediments and is bioaccumulated in the food chain until it accumulates in top predators (e.g. tuna) where it can reach unhealthy levels.
The average Hg concentration in seawater is 0.019 ug/L (Britush coastal waters)

Why is mercury used in thermometres?
Mercury thermometres aren't used much, because the mercury inside is poisones, But the reason that mercury used to be used is because Mercury expands rapidly, conserning the temperature e.g. if it gets hotter, the Mercury expands, so there is more of it. So, when you're measuring the tempurature, you're actually measuring how much mercury is there, therefore telling you what the temperature.
Is the liquid in the thermometer harmful?
Mercury. Very much so. But you have to drink it for it to be so.
As someone goes dives deeper in a ocean they have more PSI acting upon them If this ocean was mercury would the same pressure be greater or less?
Pressure in a fluid at a certain depth H is proportional to the density of the fluid. Since Mercury has a much higher density then water it will exert a much larger pressure at the same depth.
Why do penguins spend so much of their lives in the ocean?
They spend so musch of their lives in the ocean so they can hunt for food so they can survive.
