Annotated record of the detailed examination of Mn deposits from the Blake Plateau and the U.S.A. East Coast Continental Margin@en

ur continuous photographic transects (45 to 90 km in extent) were made with deep-towed, wide-angle cameras over the manganese pavement region of the Blake Pla¬teau. The photos indicate that the pavement is covered by discontinuous, mobile sand patches and that zones of transition exist between the pavement and manganese-nodule areas.本研究采用深拖式广角相机，在布莱克海台（Blake Plateau）的锰质覆层（manganese pavement）区域完成了延伸范围为45至90千米的连续摄影样带观测。所获照片显示，该锰质覆层被不连续的可移动沙斑所覆盖，且在锰质覆层与锰结核（manganese nodule）区之间存在过渡带。
