Initial Core Description (ICD)

The central operation of the LRC Core Facility is to help facilitate, support, and standardize procedures for initial core description. ICD consists of nondestructive measurement of bulk sediment geophysical properties, division of the core into working and archive halves, surface preparation, digital imaging of the whole core, and macro- and microscopic identification of sedimentary structures and composition. Comprehensive and consistent description is too often overlooked in the drive to sample and analyze lake sediment cores, but this documentation provides an essential basis for all further study.
