Arctic Ocean Mammals Are Safe for Now


Arctic Ocean mammals are safe for now, but their future survival depends on whether the ocean will maintain its regularity in climate temperatures. Mammals that migrate into the Northern Hemisphere are highly adaptable to icy waters consistent with the cool temperatures on the continent of Antarctica. Yet, the Arctic Ocean’s climate changes drastically throughout each year. Based on any given season, the Arctic Ocean could retain temperatures ranging from -40 degrees Fahrenheit to 50 degrees Fahrenheit.

During the coolest months, much of the Arctic Ocean is frozen with sheets of heavy ice spanning across its terrain. While the Arctic Ocean is a host to about 25 mammals, many of them are on the National Geographic’s Endangered Species list. Not all of mammals that live in this region depend on other mammals as a food source. Most of the mammal’s primary nourishments are derived from underneath the blue waters of the ocean.

The Arctic Ocean itself has a visibly interchangeable landscape all throughout the year. At times, the icy ocean surface which is normally hard, thaws and cracks into hundreds of different ice pods. When the icy sheets begins to melt during the summer, the ice fragments can be observed floating independently across the oceanic terrain. Since Arctic mammals are natural swimmers, they easily adapt in this type of environment.

Arctic Ocean mammals are safe for now, though scientists will soon begin analyzing the temperament of the ice caps. They want to gain a collective collaboration of findings. Researchers have already confirmed that global warming affects the Arctic Ocean more than any other place in the world. Both scientists and researcher agree retesting previous findings is the best method to protect the declining lineage of endangered species in the North Pole.

According to sources, Artic Ocean mammals that are on the endangered species list include polar bears, walruses, and whales. Oceanographers and geographers affirm that the mammals thrive abundantly in the icy environment because they have unique blood levels, bone capitates, and fur that allow them to survive.

Because of the controversy over global warming, many researchers have questioned whether the abnormal heat temperatures will affect the Arctic Ocean mammals. Biologist Todd Atwood, who heads the U.S. Polar Bear Research Program, said he is hopeful that their program will be able to provide data on the population and conservation of the polar bear. Atwood further explained, “researchers plan on returning to the field next spring to collar more bears and gain insights into their enigmatic lives in one of the world’s least forgiving environments.”

The Arctic Ocean is home to many other marine species. Because the Arctic Ocean is not as deep as the world’s other four oceans, it is the essential source of food for its inhabitants. Penguins, seals, cod fish, shrimp amphipods, copepods, and algae all thrive in the waters underneath the layers of ice.

The Arctic Ocean mammals are safe for now, however, scientists are concerned if they will survive or become extinct in the next following years. Recently, scientists revealed that the climate, where these mammals live, may soon lose its coldest temperatures as a result of global warming. If climate change continues then the heightening heat indexes will most likely have a negative effect on the mammals living in the Arctic Ocean.
