(Table S3) In situ Mg and Sr measurements in diagenetic cements and muricae of ODP Hole 143-865B, 15 micrometer beam

Sediment depth is given in mbsf. The age model was constructed using the published nannofossil biostratigraphy (Bralower and Mutterlose, 1995) and the ages assigned to the datums upon which this biozonation is based (Berggren et al. 1995). Measuerment using a 15 micrometer beam spot size.
