Nitrogen Sea

Nitrogen Seas are essentially what they sound like. Cold, icy worlds covered almost entirely by an endless ocean of Fd:Liquid Nitrogen.They have an unbreathable atmosphere (probably pure nitrogen gas), so you'll want oxygen as well as some sort of protection against the frigid temperatures. The surface landmass primarily consists of Snow and Ice islands that float loosely on the ocean surface, with sparse growths of frozen trees.
