RV Langseth Operations

Jun 5, 2023

R/V Langseth Operations Calendar Years 2025-2026

Dear Colleagues,

The National Science Foundation (NSF) Division of Ocean Sciences (OCE) in the Directorate of Geosciences (GEO) has been informed that Lamont-Doherty Earth Observatory, Columbia University, is considering plans to extend operations of the Research Vessel Marcus G. Langseth into the calendar years 2025 and 2026.

NSF will accept proposals to use the R/V Langseth in the Atlantic, Gulf of Mexico, and eastern Pacific for the calendar year 2025. The Marine Seismic Research Operations Committee (MSROC) is currently developing a regional plan for the calendar year 2026.

Per the general guidance for requesting ship time on Global-class ships, Principal Investigators should submit proposals at least 18 months prior to the requested start date of the cruise. Final schedules will be determined collaboratively between the PIs, operators, UNOLS, environmental compliance authorities, and NSF.

Ship schedules depend on many factors, and the pandemic has caused delays and rescheduling throughout the U.S. Academic Research Fleet. The schedule may shift if there are unanticipated problems.

Any questions may be directed as follows:


James McManus

Division Director, OCE
