CONTENT OF ORGANIC MATTER IN THE BOTTOM SEDIMENTS OFF LUTZOW-HOLM BAY COLLECTED BY THE 2nd JAPANESE ANTARCTIC RESEARCH EXPEDITION
The samples investigated were collected off Lutzow-Holm Bay in Antarctica by Dr. T. TORII aboard the "SOYA", research ship of the 2nd Japanese Antarctic Research Expedition (1957-58). The summary of the results is as follows (See the appendix). (1) Organic carbon in dry sediments ranges be...
