You mean Glomar Explorer. This ship tried to recover a sunken Soviet submarine under the cover of mining manganese nodules. http://en.wikipedia.org/wiki/GSF_Explorer

The Glomar Challenger was the drill ship used by the Deep Sea Drilling Project from 1968 until 1983, verifying seafloor spreading, drying up of the Mediterranean Sea, and making many other discoveries. http://deepseadrilling.org/

The Explorer was considered as a possible vessel for the subsequent Ocean Drilling Program, but the JOIDES Resolution (aka SEDCO/BP 471) was selected instead. http://odplegacy.org/

The Resolution continues to operate as part of the Integrated Ocean Drilling Program, along with the Japanese ship Chikyu, and other vessels of opportunity hired by the European Science Organization. http://iodp.org
