Acquisition of a Film Scanner Facility for the Study of Ocean Floor Photography

哥伦比亚大学的拉蒙特-多尔蒂地质观测站将获得一台35毫米胶片扫描设备，该设备将提供给整个东北部的调查人员。扫描仪以非常高的分辨率将黑白和彩色胶片数字化。然后，这些数字数据可以被编目并存储在各种计算机设备上。它将用于处理海底薄膜，并将特别有用的立体对，从底部粗糙度光谱可以计算。其他的研究应用包括海底沉积物地质剖面的组装，熔岩流的相对年龄定年，以及沉积物岩心的颜色剖面。它还将提供对拖曳照相机和载人潜水器获得的大量海底照片进行数字化存档的能力。

Lamont-Doherty Geological Observatory at Columbia University will acquire a 35 mm film scanning device that will be made available to investigators throughout the Northeast. The scanner digitizes black & white and color film with very high resolution. The digital data can then be cataloged and stored on a variety of computer devices. It will be used for processing films of the seafloor and will be especially useful for stereo pairs from which bottom roughness spectra can be computed. Other research applications include the assembly of geological cross-sections of submarine escarp- ments, relative age dating of lava flows, and color profiling of sediment cores. It will also provide a capability to digitally archive large collections of seafloor photographs obtained by towed camera vehicles and manned submersibles.
