Having generated the world with this seed, you will begin the game on the coast with icebergs. This is a good and picturesque place to build a base.
Icebergs are not very common in Minecraft, but now you do not have to look for them for a long time. A large number of ice blocks will be right in front of you, and you don’t even need to build a boat to get to them.
