Here's an incredible time-lapse video of an icebreaker navigating through Antarctic ice.
The video is narrated by Cassandra Brooks, a doctoral student at Stanford University studying Antarctic Ocean policy.
Brooks condensed two months of footage of the Nathaniel B. Palmer icebreaker travelling through the Ross Sea in Antarctica into about five minutes for this stunning video.
"Each day was a new stunning scene. The ice changing colour with the phases of the sun and seemingly growing thicker every day as the temperatures dropped and daylight decreased," Brooks told the Star.
Brooks and fellow research scientists were on the boat studying the Ross Sea ecosystem. The Ross Sea is "one of the last remaining stretches of ocean on Earth that has not been harmed by human activity," according to the Antarctic and Southern Ocean Coalition.
She blogged about her experiences on the Nathaniel B. Palmer, a National Science Foundation research cruise for the National Geographic's Ocean Views blog.
