disciplines of modern Earth science with the inception of
the hugely successful international deep ocean drilling
collaborations which began in the 1960s. The Deep Sea
Drilling Project (DSDP, 1968–1983) and its successors,
the Ocean Drilling Program (ODP, 1985–2003),
Integrated Ocean Drilling Program (IODP, 2003–2013),
and now the International Ocean Discovery Program
(IODP, 2013–present), have collectively recovered thousands of kilometers of sediment cores from the world’s
oceans ((“Ocean Drilling” by Kiyoshi, this volume) see
