Thousands of Penguin Babies Die in the Antarctic

Thousands of penguin babies have starved to death in the eastern Antarctic recently . Observers found thousands of unhatched eggs and lifeless baby penguins  on the coast. According to scientists , only two baby penguins survived during the 2017 breeding seasonAdélie penguins live in colonies that consist of thousands of animals.  It is the second time that a whole colony has been wiped out after no babies survived in 2015.

The World Wildlife Fund says that krill fishing in the area has led to the starving of penguin babies. Officials state that fishing in the area may permanently endanger the whole penguin population in the Antarctic.

Another reason for the declining number of Adélie penguins is possibly climate change.  In regions where ice gets thicker, adult penguins must  travel further away from the shore in order to find food. When they get back they find many of their babies already dead.

The WWF  and other organisations now demand that the eastern Antarctic coastline be declared a Marine Protected Area in order to help endangered penguins. Commercial fishing should be banned around these areas .

Adélie penguins live along the Antarctic coast  and usually breed from October to February.  They lay eggs in nests made up of stones.

Massive Hole Discovered in Antarctic Ice

Scientists have discovered a gigantic hole that has reappeared in the Antarctic ice. It is about the size of the Netherlands and is located around the Weddell Sea.

In the 1970s climatologists found a similar hole at almost the same spot. At that time  they didn’t have the observation equipment that they have now, so they couldn’t study the hole closely enough. After a few years it disappeared . Last year, the hole came up again.

Researchers cannot explain how the hole emerged.  One theory is  that warmer salt water from deep under the Antarctic ice sheet  may have come up and mixed with cold water near the surface, thus , melting the ice sheet above.  Normally a thick layer of ice covers Antarctica at the end of the  southern winter. Scientists also claim that it may be connected to climate change and global warming.

Such a hole in the ice is called a polynya.  Although not totally uncommon, it is strange that the hole in the Antarctic ice has appeared very far from its edge . Usually such holes are found in coastal regions.

Climatologists are not sure whether the hole will have an impact on the water temperature in the world’s oceans. If warmer water continues to surface to the top of the hole it may stay there for a longer period of time because it would then be difficult for ice layers to form.

Severe weather conditions during the Antarctic winter make it difficult to find holes in the ice . This is the second time in two years that such a hole has emerged , although last year’s was not that big.
