Tardigrade fauna of the South Sandwich Islands, maritime Antarctic
The maritime Antarctic South Sandwich Islands are an isolated oceanic archipelago of volcanic origin lying between 56º18'S, 27º34'W and 59º27'S, 27º22'W. All the islands are of recent origin (maximum ages 0.5–3 million years) with many still exhibiting some form of volcanic activ...
