Ship Operations - R/V Langseth

Lamont-Doherty地球观测站获得资金，在研究船Marcus G.上进行同行评审的NSF科学海上作业。Langseth（Langseth）for CY 2012.在2012年，R/V Langseth计划有六个科学项目，包括195个预定的运行日。所有六个NSF科学项目都需要地震能力。一个方案是地震和活塞/多芯的组合，这将是Langseth的第一个。这是一项为期五年的合作协议，协议每年的资金将通过谈判确定，并取决于支持NSF资助研究的海上天数。R/V Langseth作为联合国后勤基地的一艘船舶运营，遵守联合国后勤基地的安全标准和NSF检查。Langseth为美国学术界提供了改进的多道地震（MCS）能力。该船能够部署多个水听器阵列和线声源气枪阵列，提高了数据采集的质量和可靠性。这种独特的成像能力使科学家能够解决广泛的海洋地球科学问题。沿着这一特殊能力，我们正在寻求发展一种增强的通用能力，可用于开展研究，支持世界各地的各种海洋科学学科。Langseth的独特能力提高了美国学术界多通道地震数据采集的效率，质量和可靠性，使海洋地球科学中最广泛的问题能够通过大幅提高成像能力来解决。虽然这艘船的地震能力是调查地球深部结构的科学计划的主要重点，但在地球上很少探索的地区进行的一般海洋学和海洋哺乳动物调查将深入了解影响地球气候和海洋生物资源的当地和全球环境条件。朗塞斯号与联合国海洋法办事处舰队中的其他船只一样，不仅仅是收集科学数据的工具。它是一个学习工具，一个大学教育设施，使年轻的地球科学家能够学习他们行业的实践方面。2012年船舶运营计划提供了一个机会，在未开发的地区收集新的，更高分辨率的数据，这将大大增加我们对地球和海洋科学的基本问题，包括气候变化和自然灾害，如地震和海啸的理解。外展工作包括船舶图尔斯旅游和社区外展通过L-DEO赞助的活动，以朗塞特为特色。

Lamont-Doherty Earth Observatory is awarded funding to carry out peer-reviewed NSF scientific sea-going operations on Research Vessel Marcus G. Langseth (Langseth) for CY 2012. In 2012 the R/V Langseth has six science programs planned, encompassing the 195 scheduled operating days. All six NSF science projects will require a seismic capability. One program is a combination of seismic and piston/multi-coring, which will be a first for the Langseth. This is a five-year cooperative agreement, and funding for each year of the agreement will be negotiated and is dependent on the number of days at sea in support of NSF-funded research. R/V Langseth operates as a UNOLS ship, adhering to the UNOLS safety standards and NSF inspections. Technical Merit The Langseth provides the U.S. academic community an improved multi-channel seismic (MCS) capability. The ship is able to deploy multiple hydrophone arrays and linear sound source air gun arrays, which improve the quality and reliability of data acquisition. This unique imaging capability enables scientists to tackle a wide range of marine earth science problems. Along with this special capability we are seeking to develop an enhanced general-purpose capacity, which can be used to conduct research in support of various marine science disciplines in locations around the world. The unique capabilities of the Langseth improve the efficiency, quality and reliability of multichannel seismic data acquisition for the US academic community, enabling the widest range of problems in marine earth sciences to be tackled with substantially improved imaging capability. Although the seismic capability of this vessel is the primary focus for scientific programs investigating the deep earths structure, general oceanographic and marine mammal investigations in little-explored parts of the earth will provide an insight into local and global environmental conditions affecting earths climate and the living resources of the sea. Broader Impacts The Langseth, in common with the other ships in the UNOLS Fleet, is more than just an instrument for the collection of scientific data. It is a learning tool, a university educational facility that allows young earth scientists to learn the hands-on aspects of their trade. The 2012 Ship Operations program provides an opportunity to collect new, higher resolution data in unexplored areas, which will add significantly to our understanding of fundamental problems in the earth and ocean sciences, including climate change and natural hazards, such as earthquakes and tsunamis. Outreach efforts include ship tours and community outreach through L-DEO sponsored activities that feature the Langseth.
