Annotated record of the detailed examination of Mn deposits from The Blake cruises stations

In this volume, Agassiz gives a detailed account of the results of the cruises of the Coastal Survey Steamer "Blake". The cruises covered the East coast of the United States along with some parts of the Caribbean waters and the Gulf of Mexico. The deep sea formations are described in detail. It is during these cruises that the first nodule from the Blake Plateau was recovered and its mixed nature of both phosphate and manganese deposit was identified.

在本册中，阿加西详细记述了海岸测量蒸汽船"布莱克号"巡航任务的全部成果。此次巡航范围覆盖美国东海岸、加勒比海部分海域以及墨西哥湾。报告对深海地质构造进行了细致描述。正是在本次巡航期间，科研人员首次从布莱克海台（Blake Plateau）采集到结核样本，并确认其兼具磷酸盐沉积与锰矿沉积的混合属性。
