Okay kiddo, let's talk about something called "seabed gouging by ice". Do you know what ice is? It's frozen water! And sometimes when there is a lot of ice in the ocean, it can scrape and dig on the bottom of the sea, like when you scrape your knee when you fall down. That's what we mean by "gouging".
The ice that does this is usually big and heavy, and it moves around because of the wind and the currents in the ocean. When this ice moves, it can break off pieces of the ocean floor or even make new, deeper grooves in it. Think of it like someone dragging a heavy, sharp tool across a sheet of paper and making a deep line in it.
Seabed gouging by ice can be a big problem because it can change the shape of the ocean floor, which can affect the animals and plants that live there. Plus, if we're not careful, it can damage things like oil rigs or other structures that might be on the bottom of the sea.
So, scientists study seabed gouging by ice to see how much it is happening and to try to predict where it might happen in the future. That way, we can better protect the ocean and everything that lives in it.
