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 […]

Antarctica’s Native Insect

Antarctica’s Native Insect - Antarctica Journal News

Antarctica’s native insect, the Antarctic Midge is a flightless insect that can survive nine months frozen at temps of at least negative 15 degrees Celsius.  It loses about 70% of its body fluids and can live for about a month without oxygen.  The midge survives because of its combination of rapid cold hardening and warm temperatures in its underground habitat.  […]

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 […]

King Crabs Are Invading Antarctica

King Crabs Are Invading Antarctica

The waters off the west coast of Antarctica has started to warm up over the past 50 years. The temperature has risen about 2.5 degrees Fahrenheit, warmer than the average water temperature worldwide.  It has reached the temperature of 34 degrees which is warm enough for king crab to survive.  Normally the king crab live on the continental slopes and […]

Ozone Hole Shrinking Over Antarctica

Ozone Hole Shrinking Over Antarctica - Antarctica Journal News

According to NASA and NOAA (National Oceanic and Atmospheric Administration) due to the warmer weather, the ozone hole has measured its smallest size on record over Antarctica.  This has happened three times in the last 40 years where the weather conditions have caused the ozone depletion to slow.  Even though this is good news it is not a sign that […]

Nasa: Antarctic ice-shelf will be gone by 2020

According to a new study by Nasa, Antarctica’s Larsen B ice-shelf is on course to completely disintegrate within the next five years. Studies show that the 10,000-year-old ice shelf, after partially collapsing in 2002, is “quickly weakening.” “These are warning signs that the remnant is disintegrating,” said Ala Khazendar of Nasa’s Jet Propulsion Laboratory (JPL) in Pasadena, California. “Although it’s […]
