Which marginal seas are part of the Arctic Ocean?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

The Arctic Ocean features a broad Eurasian continental shelf that is divided by islands and peninsulas into five main marginal seas. These marginal seas are:1

Barents Sea1
Chukchi Sea21
East Siberian Sea1
Kara Sea31
Laptev Sea1

While these marginal seas occupy 36 percent of the total area of the Arctic Ocean, they contain only 2 percent of its water volume. Most major rivers discharge into these shallow areas, which significantly influences the surface-water conditions of the ocean.1
