=== Geologic drilling ===
Drill holes have recovered cores of rock from the western edges of the sea. The most ambitious recent efforts are the [[Cape Roberts Project]] (CRP) and the [[ANDRILL]] project.<ref>{{Citation|last1=Barrett|first1=P.

During 2018, Expedition 374 of the [[International Ocean Discovery Program]] (IODP), the latest successor to the DSDP, drilled additional holes (U1521–1525) in the central Ross Sea for determining [[Neogene]] and [[Quaternary]] ice sheet history.<ref>{{Cite book|title=International Ocean Discovery Program Expedition 374 Preliminary Report|last=Robert M.
