Lots of people are looking forward to the arrival of spring on Tuesday, but on Sunday the Discovery Channel will offer viewers a close-up look at earth's coldest frontiers with the premiere of Frozen Planet.

Created by the same crew that produced the 2006 Planet Earth documentary series, Frozen Planet includes scenes filmed in every nation within the Arctic and Antarctic circles.

The project's website says 2,356 days were spent filming in the field and 1.5 years at sea. More than 6 months were spent filming on sea ice and 134 hours beneath the ice in polar oceans. ABC's Nightline offered a preview Thursday night (sorry for the commercial lead-in):

Discovery, which made headlines this week for severing ties with Man vs. Wild star Bear Grylis, airs the first 2 hour-long episodes of the 7-part series Sunday at 8 and 9 p.m. ET and PT.
