Documentation of sediment cores of HEINCKE cruise HE405

The half sections for archive were used for core imaging and description on ship board (GeoB 17701-1, GeoB 17703-1, GeoB 17705-1, GeoB 17708-1, GeoB 17711-1, GeoB 17715-1) and onshore (all others). The images were made using a handheld Canon EOS 450D reflex camera under fluorescent light conditions. A true color chart was used for color control. The core description provides information about core section length and position, core section number, core image, color, graphic lithology, sedimentary structures, coring disturbance, grain size and description text. Sediment color was determined qualitatively for core intervals using Munsell soil color charts. Grain size of the sand fraction was determined using a sand ruler, ranging from 63-90 µm for very fine sand, 90-250 µm for fine sand, 250-710 µm for medium sand, and 710-2000 µm for coarse sand.
