Ship Operations - R/V Langseth

拉蒙特-多尔蒂地球观测站获得资助，将于2012年在研究船Marcus G.Langseth(朗塞斯)上开展经过同行评审的NSF科学出海作业。2012年，R/V朗塞斯计划了六个科学项目，包括195个预定的运营日。美国国家科学基金会的所有六个科学项目都将需要地震能力。其中一个项目是地震和活塞/多岩心的结合，这将是朗塞特的第一次。这是一项为期五年的合作协议，协议每一年的资金将通过谈判获得，并取决于支持NSF资助的研究的海上天数。R/V朗塞斯作为联合国难民事务高级专员办事处的船只运作，遵守联合国难民事务高级专员办事处的安全标准和国家安全部队的检查。技术优点朗塞特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性声源气枪阵列，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。除了这一特殊能力外，我们正在寻求发展一种增强的通用能力，这种能力可用于开展研究，支持世界各地的各种海洋科学学科。朗塞特的独特能力为美国学术界提高了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显著提高的成像能力得到解决。尽管这艘船的地震能力是研究地球深层结构的科学计划的主要焦点，但在地球上很少被探索的地区进行的一般海洋学和海洋哺乳动物调查将提供对地球气候和海洋生物资源影响的当地和全球环境条件的洞察。更广泛的影响“朗塞特”号与联索政治处舰队中的其他船只一样，不仅仅是收集科学数据的工具。它是一种学习工具，是一种大学教育设施，允许年轻的地球科学家学习他们所从事的行业的实践方面。2012年船舶运营计划提供了在未勘探区域收集新的、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了解，包括气候变化和自然灾害，如地震和海啸。外展工作包括船只之旅和通过L-DEO赞助的以朗塞特为特色的活动进行社区外展。

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.
