  • Research looks into Contrasts in Sea Ice towards the Polar Regions

The latest research looks into contrasts in sea ice towards the polar regions.

The sea ice covering the Antarctic continent has increased slightly while the same has not occurred in the Arctic region. In the latter, on the contrary, there has been a great loss of sea ice.

NASA has observed this findings and come up with reasons for the occurrence of these phenomenon. A team of researchers employed satellite radar, top-of-the-sea temperatures, land terrain and bathymetry information to study the physical processes and other natural things connected to Antarctic sea ice. 

Two factors played a crucial role in the equation. One was the surface features of Antarctica. The other was the depth of the oceans surrounding the frozen continent.

These affect the raging winds and tempestuous ocean currents that shape Antarctica. The difference between the Arctic and Antarctic regions was due to the surrounding forces that impinged on these cold polar areas.

Antarctica is covered by sea ice in accordance with the season. During September, the sea ice reached its maximum extent, while in February it retreated by 17%. Since the environment-savvy 70s, these figures have been pretty much stable in their progression and recession. 

Researchers have given various explanations about Antarctica’s stability. The global temperatures have tended to increase drastically.

Could the ozone hole be to blame for this phenomenon?

Or is the meltwater from off the coast of Antarctica making the sea water salty in nature and hence subject to ice formation?

Are the winds causing the ice to grow back thicker?

Some of these factors may be increasing the Antarctic sea ice. Yet the answer remains enigmatic at best. A new approach is needed to tackle these difficult questions and provide satisfying answers. 

The ice and water along with several other factors undergo complex interactions and permutations affecting the overall weather. Antarctica seems to be showing odd trends that defy the scientists’ models and graphs. It just goes to show you that Mother Nature is always two steps ahead of man.

NASA’s radar satellite is currently giving back information gathered about Antarctica. The Southern Ocean plays a vital role in the weather conditions of Antarctica. NASA with its space advantage tends to provide the most reliable and trustworthy evidence that has ever been gathered up until now.
