数字岩心图像为科学研究人员提供了最高分辨率的岩心特性。在综合大洋钻探计划远征303期间，JOIDES Resolution上使用的数字岩心扫描仪捕获了每毫米约10个像素的岩心。然而，海洋钻探界在利用这些数字数据方面进展缓慢，而不是高度详细的图片。在这项研究中，我们说明了一种快速，简单的方法来提取深度缩放的数字数据的核心图像。然后，这些数据可以通过图像增强进行处理，以突出显示原始图像或岩心中不容易识别的细节。其他数据，如多传感器轨道岩心扫描，可以很容易地覆盖在图像上。我们使用数字核心图像，以检查核心失真开发的表集为5远征303网站，精确地映射功能的网站复合到这些相同的功能，在每个孔在该网站的个别核心。一般来说，结果表明，在80%的情况下，复合材料截面内的特征与不用于复合材料的截面中的相同特征的距离在35 cm以内。
Digital core images offer the highest resolution realization of core properties available to scientific investigators. The digital core scanner used aboard the JOIDES Resolution during Integrated Ocean Drilling Program Expedition 303 captured ~10 pixels per millimeter of core. The ocean drilling community, however, has been slow to utilize these digital data as other than highly detailed pictures. In this study we illustrate a fast and simple method to extract core images as depth-scaled digital data. These data can then be manipulated through image enhancement to highlight detail not easily recognized in the original image or cores. Other data such as multisensor track core scans can be easily overlain on the images. We use digital core images to examine core distortion by developing sets of tables for five Expedition 303 sites that precisely map features in the site composite to those same features in individual cores from each hole at that site. In general, results show that in 80% of instances features within the composite section line up to within 35 cm of the same features in sections not used for the composite.
