R/V Marcus G. Langseth
R/V Langseth - US National Facility
The R/V Marcus G. Langseth joined the U.S. academic fleet in 2008 and serves as an oceanographic research vessel, with special focus on marine seismic profiling. The Langseth is owned by NSF and operated by Columbia University’s Lamont-Doherty Earth Observatory under a cooperative agreement.
The Langseth is distinct among ships in the academic fleet in that it is a designated National Facility. This status highlights the Langseth’s key role in serving a broad community by providing a unique capability to image beneath the oceans. Unlike other ships in the fleet, the Langseth is overseen by an oversight panel, the Marcus Langseth Science Oversight Committee (MLSOC), which consists of scientists from the community and serves as a liaison between the science community, the facility operator, and the NSF.
With the R/V Langseth facility, the academic community has a fully capable 3D seismic vessel. 3D seismic reflection imaging provides a view of the Earth’s interior. In addition to the new 3D capabilities, the Langseth facility offers advancement in 2D imaging, both for reflection imaging and for sourcing wide-angle surveys using ocean-bottom seismometers and onshore instruments. Owing to an exceptional source array and longer streamer cables, the Langseth can collect 2D data that penetrates deeper and with greater clarity than ever before.

In addition to supporting investigator-driven science on these scientific themes, the seismic imaging tool undergirds many U.S. and international science initiatives, including:
• IODP, the Integrated Ocean Drilling Program • GeoPRISMS (the MARGINS successor program) • R2K (the RIDGE 2000 initiative) • Continental Dynamics • The Ocean Bottom Seismometer Instrument Pool • IRIS/PASSCAL, including EarthScope

R/V Langseth - Capabilities
Facility Capabilities The Langseth facility provides a unique combination of capabilities for imaging the ocean, the seafloor, and the solid Earth beneath the sea — as well as general oceanographic instrumentation.
Current shipboard equipment includes: • 3D seismic capability: including four 6-km-long hydrophone streamers and dual airgun source • Long-offset capability, with possibility of towing up to a 15-km-long streamer in 2D mode • Tuned, linear source array, consisting of up to 36 airguns with a total capacity of 6600 cu. in. • Kongsberg EM122 multibeam sonar system for seafloor mapping • Knudsen 3260 Sub-Bottom Profiling • RDI 75 kHZ acoustic doppler current profiler (ADCP) to measure ocean currents • Seabird thermosalinograph to measure seawater temperature and salinity • Sippican expendable bathythermograph (XBT) launcher • Bell BGM-3 gravimeter • Towed Geometrics 882 magnetometer to measure gravity and magnetic fields • Uncontaminated Seawater System for other measurements like underway pCO2

SERCEL Seal 408 Streamer System Upgrade
**In July 2015 - NSF Funded Seal 408 with Sentinel Solid Streamers Seismic System Upgrade**
• Replaced existing original Western SYNTRAK System • Allows for towing longer 2D solid streamers up to 1x15km • Modern supported system

The regional framework is designed to reduce overall data acquisition costs, and:
• Provide guidance about when to submit proposals for research in a particular area. • Encourage investigators (both US and potential international teams) with new ideas for work along the path to submit a proposal that could mesh geographically (modest transit) with the framework path. • Provide rotating access to regions of scientific interest over a timeframe of several years. • The framework can flex somewhat in response to demand. NSF proposals for projects along the path should be submitted about 18-30 months prior to potential cruise dates. Details of the path can evolve but the main regions are expected to be retained. The length of time in one region will reflect demand and science timeliness considerations for the next region(s) along the path.
•*** Allow time and provide advance notice for international and/or industry partners time to develop projects if interested in using vessel.
NSF Regional Framework Plan for Marine Seismics— (Status as of May 2016) The vision for this framework is that it can guide planning ~4 years into the future. Subsequent path route(s) will be announced approximately biennially, based on NSF understanding of projected interest areas and MLSOC and community input.
