Can seawater be used to thicken arctic ice effectively?

Seawater can help make Arctic ice thicker, just like adding salt to ice cream makes it harder to melt.

When seawater freezes, it becomes ice, but not all of the water turns into ice, some stays as salty liquid underneath. This salty part is heavier than fresh water, so it sinks down, pushing up the fresher water on top. That fresher water then freezes too, making the ice thicker over time. It’s like stacking blocks one on top of another to make a taller tower, each layer adds more height.

In the Arctic, ice gets thinner during warm seasons because of melting. But when seawater freezes, it helps the ice grow back thicker. Think of it as a slow but steady game of building blocks, every winter, the ice gets a little bigger and stronger again.

So even though seawater is salty, it plays an important role in keeping Arctic ice from getting too thin, like a friendly helper that makes ice grow just a bit more each year.
