Ocean Drilling Program (ODP) Leg 210 is one of very few deep-sea legs drilled along the eastern Canadian continental margin. Most other drilling on this margin has been carried out by the petroleum industry on the shallow-water regions of the Scotian shelf and the Grand Banks (see Doeven, 1983, for nannofossil studies). Deep Sea Drilling Project (DSDP) Leg 12 Site 111 and ODP Leg 105 Site 647 were drilled in the general vicinity of Leg 210 but recovered no appreciable Lower Cretaceous (Albian-Cenomanian) sediments. Site 111 yielded indurated limestones dated tentatively as late Albian-early Cenomanian, whereas Site 647 encountered no Albian-Cenomanian sediments.
Two sites (Sites 1276 and 1277) were drilled during Leg 210 in the Newfoundland Basin with the primary objective of recovering basement rocks to elucidate the rifting history of the North Atlantic Basin. The location for Leg 210 was selected because it is conjugate to the Iberia margin, which was drilled extensively during DSDP/ODP Legs 47B, 103, 149, and 173. A secondary but equally important objective was to recover the overlying sediments with the purpose of studying the postrift sedimentation history of this margin.
