Eli5: Do ships cause the ocean to be higher than it normally would be?

383 viewsOtherPlanetary Science

I’m not sure if this is a shower thought and I’m sure I sound like a complete tool, but thinking about it on a small scale makes a lot more sense. It’s like if you fill a bathtub to the brim and then climb in, the water will overflow. I have to imagine in SOME WAY having hundreds of thousands of ships in the ocean has to be affecting the water level. Is this already a thing or do the people reading this want what I’ve been smoking? 😂

Yes. Ships displace the water they are in, and it has to go somewhere. A vessel that displaces 20 tons, would push 4705.882 (ish) gallons of water or 18 cubic meters of water out of the way.

But the effect on a planetary scale is so small there’s no way to accurately measure it.
