Academic Seismic Portal at LDEO

The MGDS Academic Seismic Portal at Lamont-Doherty Earth Observatory (ASP-LDEO), now part of the IEDA Data Facility, was initiated in 2003 to preserve and provide open access to multi-channel seismic (MCS) and single channel seismic (SCS) field data collected for academic research supported by the US National Science Foundation. Multi-channel data are primarily from the marine seismic vessels operated by Lamont-Doherty Earth Observatory of Columbia University. Modern single channel seismic data from other vessels including the R/V Palmer and USCG Healy, as well as data from portable seismic systems, are also served. The development of the Academic Seismic Portal has focused on the need to recover high value MCS data from older surveys as well as to establish sustainable procedures for preservation of data from modern programs. During the final two years of R/V Ewing operations, procedures were established for routine transfer of MCS data along with navigation and acquisition parameters, and other needed documentation to the ASP. Transfer of seismic data and acquisition information is now routine for the National Marine Seismic Facility, the R/V Marcus G. Langseth, which began science operations in February 2008. Data are documented and incorporated into the data system with full access restrictions protecting the scientists' rights to exclusive access during the proprietary hold period. Submission of data to the ASP helps ensure that NSF requirements for data sharing as outlined in the NSF OCE Data Policy are satisfied. Data from the Academic Seismic Portal at UTIG has been migrated to LDEO. As we continue to verify the accuracy and completeness of this data, there may be temporary issues with some seismic metadata and web services.

哥伦比亚大学拉蒙特-道奇地球观测站的MGDS学术地震门户（ASP-LDEO），现属于IEDA数据设施，自2003年起启动，旨在保存并提供对多通道地震（MCS）和单通道地震（SCS）野外数据的开放访问，这些数据是由美国国家科学基金会资助的学术研究收集的。多通道数据主要来自哥伦比亚大学拉蒙特-道奇地球观测站运营的海洋地震船。还包括来自其他船只的现代单通道地震数据，例如R/V Palmer号和USCG Healy号，以及便携式地震系统数据。学术地震门户的发展侧重于从较老的调查中恢复高价值的MCS数据，以及建立对现代项目数据进行可持续保存的程序。在R/V Ewing号运营的最后两年中，建立了将MCS数据、导航和采集参数以及其他所需文件常规转移至ASP的程序。对于国家海洋地震设施、R/V Marcus G. Langseth号（自2008年2月开始科学运营）而言，地震数据和采集信息的转移已成为常规操作。数据被记录并纳入数据系统，同时通过完全访问限制保护科学家在专有期内的独家访问权。将数据提交至ASP有助于确保满足国家科学基金会 outlined in the NSF OCE Data Policy 规定的数据共享要求。来自德克萨斯大学地球与海洋科学研究所（UTIG）的学术地震门户数据已迁移至LDEO。随着我们继续验证数据的准确性和完整性，可能存在一些地震元数据和网络服务暂时性的问题。
