What I like to think about is that fjords were carved out by glaciers and the sea level has certainly been lower that it was now in the past… but 1300m deep what???
…so how did Glaciers cut rock BELOW sea level? Like wayyyyyy below sea level?
It is the weight of the entire glacier bearing down and carving wayyyyyy below a depth that a chunk of ice would make sense being at, the entire glacier basically serves as a trench digging machine and as you pointed out these fjords are REALLY deep.

They were carved by Slartibartfast, not glaciers.
