Diving observations of the marine benthos at Syowa Station, Antarctica
In January 1981,15 diving observations were made on the benthos at three locations around Syowa Station (69°00'S, 39°35'E), Antarctica. A total of 87 animal species and 3 algal species were collected. At the Nisi-no-ura Cove location, qualitative and quantitative collections of the sandy b...
