Russia has mapped five new Arctic islands that were first spotted by a student using satellite imagery.

The islands, which are on the coast of the remote Novaya Zemlya archipelago in the Arctic Ocean, are the result of melting glaciers.

Marina Migunova made the discoveries in 2016 while a student at the Admiral Makarov State University of Maritime and Inland Shipping in St. Petersburg. The Moscow Times reports that Migunova was on a research vessel from Russia’s Northern Fleet when she made the discoveries. She is now an engineer on the same hydrographic vessel, the report added.

In a statement, Russia’s Ministry of Defense explained that naval and civilian scientists recently took part in an expedition to the five newly discovered islands, where “[t]opographic surveys were conducted."

The islands range in size from 900 square meters (9,688 square feet) to 54,500 square meters (585,557 square feet), according to Russian defense officials.
