ABSTRACT
Project Summary
The instrumentation requested in this proposal will be used to enhance R/V Langseth?s seismic functionality and reliability. The proposal states that replacing the existing SYNTRAK MCS system with the proposed Sercel SEAL 408 system is critical for the future of Langseth and the science community that requires it for seismic imaging. References are made to the Langseth ?Incline Village? Science workshop report in 2010, where the science priorities provided detail on future scientific goals that require a more capable system. The current system is more than 20 years old, is no longer supported and is well beyond its expected service life. In order to meet the needs of scientific community, upgrading the multi-channel seismic (MCS) capabilities of the National Seismic Imaging Facility is a necessity. The premise of the proposal is that the purchase of the Sercel SEAL 408 satisfies these requirements and does so in a fiscally responsible way.
Broader Impacts
The principal impact of the present report is under Merit Review Criterion 2 of the Proposal Guidelines (NSF 13-589). It provides infrastructure support for scientists to use the vessel and its shared-use instrumentation in support of their NSF-funded oceanographic research projects (which individually undergo separate review by the relevant research program of NSF). The acquisition, maintenance and operation of shared-use instrumentation allows NSF-funded researchers from any US university or lab access to working, calibrated instruments for their research, reducing the cost of that research, and expanding the base of potential researchers.
PROJECT OUTCOMES REPORT
Disclaimer
This Project Outcomes Report for the General Public is displayed verbatim as submitted by the Principal Investigator (PI) for this award. Any opinions, findings, and conclusions or recommendations expressed in this Report are those of the PI and do not necessarily reflect the views of the National Science Foundation; NSF has not approved or endorsed its content.
The 2015 Ocean Instrumentation II award funded a complete new Sercel 408 marine seismic recording system upgrade for the R/V Marcus G. Langseth. As the US Natiional Facility for Seismic Imaging, this recording system is at the heart of the science capability of the vessel. This upgrade allows for much better data acquisiiton, overall data quality, and greatly extends overall science capability.
The previous SYNTRAK marine seismic recording system was original to the vessel and was approaching 25 years age and was no longer possible to maintain. The new Sercel 408 system is state of the art system that is supported and capable of beign maintained. This purchase included 20km of solid seismic hydrophone streamer, redundant control electronics, and included all the other necessary accessories to install the system on the R/V Langseth.
In October 2015, the old Syntrak system was removed and new Sercel system was installed. The system was tested dockside and with harbor trials to make sure all parts of the system was functioning. The system was deployed on two successive projects in late 2015 and early 2016 with great results for both projects. The new system performed as expected with minimal downtime and few warrany replacement parts that needed to be replaced.
