Mansa Cove is the 450-metre-wide (1,480 ft) cove indenting for 300 metres (980 ft) the east coast of the small (2.6 by 1.6 kilometres [1.62 mi × 0.99 mi]) ice-free promontory forming the north extremity of Ioannes Paulus II Peninsula, western Livingston Island in the South Shetland Islands, Antarctica and ending up in Cape Shirreff. The feature was descriptively named by the 1984–85 Chilean Antarctic Expedition from the stillness of its waters (‘Quiet Bay’ in Spanish).
