This sea is named after Danish polar explorer and hydrographer, Vice Admiral Carl Frederick Wandel, who in years 1895–96 explored the coastal waters of Greenland as part of the Danish Ingolf Expedition.
This arctic sea is located at 82° north longitude and 21° west latitude. Seas farther north and northwest of the Wandel Sea were once frozen year-round but now may have open water in late summer, as of August 2018  The Wandel Sea stretches westward as far as Cape Morris Jesup. Further west is the Lincoln Sea. In the south, it stretches to Nordostrundingen. The Wandel Sea connects to the Greenland Sea in the south through the Fram Strait.
Independence Fjord and Frederick E. Hyde Fjord are two great fjords of the far-northeast Greenland coast having their mouths in the Wandel Sea. G.B. Schley Fjord and Hellefisk Fjord are smaller fjords located between both.
Among the islands the following deserve mention: Princess Thyra Island, the largest, Kaffeklubben Island, the northernmost, as well as Princess Dagmar Island, located not far from Station Nord, the only inhabited place in the area.
