Nathaniel B. Palmer is an icebreaking research vessel (RVIB) owned by Offshore Service Vessels LLC, operated by Edison Chouest Offshore, Inc. and chartered by the United States National Science Foundation. Nathaniel B. Palmer is tasked with extended scientific missions in the Antarctic. Nathaniel B. Palmer was purpose-built for and delivered to the NSF by Edison Chouest Offshore's North American Shipbuilding facility in 1992. Nathaniel B. Palmer is able to support up to two helicopters, accommodates up to 45 science and technical personnel, has a crew of 22 and is capable of missions lasting up to 65 days. The vessel is named after merchant mariner and ship builder Nathaniel Brown Palmer, credited by some historians as the first American to see Antarctica.
