Statement

Tephra occurrences with descriptive terms are included if they have greater than 25% tephra/volcanic ash (see Mahony et al. 2014 for details). Core name follows the IODP naming protocol, e.g. 127-794A represents Expedition 127, Site 794, Hole A. Depth of ash is depth in metres to the bottom of the ash layer where known, either given in the VCD text or digital data file, or measured off the VCD diagram. Depth is measured in metres below sea floor (mbsf). Age of ash is the age in millions of years, calculated using the depth below sea floor and linear interpolation of points from appropriate age-depth models. The age-depth models used are listed in the other workbook tabs, with a link to the source of the age-depth model. Some are the age-depth models generated during the expedition, but where possible we have used post-cruise age-depth models, as they are likely to have improved or refined the original shipboard age-depth models.
