Nitrogen Seas are planets with an endless ocean of Liquid Nitrogen. They are cold, icy worlds with 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.
You can find Strange Nodule and Coral at the bottom of that ocean. Garflipps have a chance to crawl on the surface, and even higher chance at the ocean floor.
Codex description
Doesn't this sound like a fun place to swim? Yea, it really isn't. Some handy liquid there, though.
Notes
These extremely cold worlds are similar to Ocean planets, except they are very icy and their oceans are Liquid Nitrogen. A Heating EPP 2 or a Cold Shield 2 augment is advised for races without cold resistance wishing to explore these worlds. Blizzberry can also provide short-lived relief, allowing one to gather the Liquid Nitrogen that they need.
