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

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.
