How Sea Ice Forms

Sea ice is formed from ocean water that freezes. Because the oceans consist of saltwater, this occurs at about minus 1.8 degrees Celsius (28.8 degrees Fahrenheit). Most Antarctic sea ice occurs annually, meaning it forms in the winter and melts during the summer. Sea ice regulates exchanges of heat, moisture and salinity in the polar oceans. It insulates the relatively warm […]

Antarctic Fish Have Ice In Their Veins

Scientists have revealed that some fish that thrive in the freezing cold waters of the Antarctic actually have ice in their veins. A protein in their system called notothenioids not only keep the fish from freezing to death, but also keeps ice crystals in their veins. Although the ice crystals would melt at temperatures just slightly above freezing, the fish […]

Blood Falls: Flowing Network Discovered Below Antarctica’s Dry Valleys

Research shows there may be an entire world underneath Antarctica’s ice-free Dry Valleys, which on the surface may seem hostile to life. Below the surface lies rivers of liquid salt water which flow into subsurface lakes, every drop of which could be swarming with microbial life. One of Antarctica’s most unique features, the briny, rusty-red colored Blood Falls, could possibly […]

The big melt: Antarctica’s retreating ice could re-shape Earth

CAPE LEGOUPIL, ANTARCTICA: From the ground in this extreme northern part of Antarctica, spectacularly white and blinding ice seems to extend forever. What can’t be seen is the battle raging thousands of feet below to re-shape Earth. Water is eating away at the Antarctic ice, melting it where it hits the oceans. As the ice sheets slowly thaw, water pours […]

New cli-fi novel pits an at-risk blue whale against Antarctic collapse

As a new generation of writers confronts global warming, a new book genre has emerged: “climate fiction”, or “cli-fi”. Russell: “In my secret heart, I hope that all these books that are now talking about climate change will help to move public opinion.” That’s Canadian novelist Craig Russell. In his recent book, Fragment, a shockwave sends a massive Antarctic ice […]

Life abounds under Antarctic ice

Despite no exposure to sunlight or fresh air for more than a million years, a lake located half a mile beneath the Antarctic ice sheet sustains an entire ecosystem, scientists have confirmed—raising the prospect that life might exist in similar environments elsewhere in the universe. Researchers had long suspected the existence of tiny life-forms living below the ice pack, and […]
