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 […]

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 […]

International team of scientists reports on Antarctic lead pollution

Researchers from Australia, Denmark, Germany, Norway, United Kingdom, and the United States conducted lead concentration measurements of sixteen ice core samples, and found that industrial air pollution has persisted Antarctica since its arrival there in 1889 and remains significant in the current century. Their study was published in Scientific Reports on July 28, and covered in Nevada‘s Review journal. Lead […]

Scientists Locate Earth’s Largest Canyon

Durham University, leading a team of international researchers believe they have discovered the largest known canyon on Earth. Utilizing precise satellite data and ground-penetrating radar, they have calculated it to be over 62 miles long and over half a mile deep at some points. More precise measurements will be necessary to confirm these findings, although that will be a difficult […]
