What are the challenges facing the researchers of the Arctic Ocean?

Explorers of the Arctic Ocean face various challenges. Firstly, these are climatic conditions: movement in the Arctic is complicated by numerous glaciers, snow drifts, etc. The temperature here is almost always below zero, which is difficult for a person to get used to.

Secondly, it is not easy for researchers to exist during the polar day and night. According to many polar explorers, it is very difficult to live 180 days in the light.

In addition, in the Arctic, people are trapped by dangers from wild animals, in particular, polar bears.
