Ship Operations - R/V Langseth

Lamont-Doherty地球观测站被授予2012年度NSF科研船Marcus G. Langseth （Langseth）进行同行评议的科学海上作业的资金。2012年，R/V朗塞斯号计划进行六个科学项目，包括195天的预定运行时间。NSF的所有六个科学项目都需要具备地震能力。其中一个项目是地震和活塞/多芯取心的结合，这将是Langseth的第一个项目。这是一份为期五年的合作协议，协议中每一年的资金将根据支持nsf资助的研究的海上天数进行协商。朗塞斯号作为联合国生命线行动的一艘船，遵守联合国生命线行动的安全标准和国家科学基金会的检查。Langseth为美国学术界提供了改进的多通道地震（MCS）能力。该船能够部署多个水听器阵列和线性声源气枪阵列，这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。除了这种特殊的能力，我们正在寻求发展一种增强的通用能力，它可以用来进行研究，以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的成像能力得到解决。虽然这艘船的地震能力是研究深层地球结构的科学计划的主要焦点，但在地球上很少被探索的部分进行一般海洋学和海洋哺乳动物调查将提供对影响地球气候和海洋生物资源的当地和全球环境条件的深入了解。“朗塞斯”号与联索特派团舰队的其他船只一样，不仅仅是收集科学数据的工具。它是一种学习工具，一种大学教育设施，可以让年轻的地球科学家学习他们贸易的实际操作方面。2012船舶作业计划提供了一个在未开发区域收集新的、更高分辨率数据的机会，这将大大增加我们对地球和海洋科学基本问题的理解，包括气候变化和自然灾害，如地震和海啸。外联工作包括乘船游览和通过L-DEO赞助的以朗塞斯为特色的活动进行社区外联。

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.
