This renewal grant will permit the continuation of an ambitious project to assess all underway geophysical data archived at the National Geophysical Data Center (NGDC), data that represent an estimated $3 to $6 billion investment for acquisition during research cruises. The shipboard data provide higher resolution than satellite data, but do not have the global coverage afforded by the satellite data. For the first time, this project will develop tools to assess the quality of the NGDC archived data and to apply corrections. This project aims to assess the quality of the underway geophysical data and to apply corrections both along-track and at critical crossover points of two shiptracks, where data should agree. The final product of this research will be new capabilities for the Generic Mapping Tools, permitting advanced analysis of crossover data and automatic handling of NGDC files, including various assessments of possible errors.

这笔更新拨款将允许继续一个雄心勃勃的项目，以评估国家地球物理数据中心（NGDC）存档的所有正在进行的地球物理数据，这些数据代表了在研究巡航期间估计30亿至60亿美元的收购投资。 船载数据比卫星数据提供更高的分辨率，但没有卫星数据提供的全球覆盖范围。 该项目将首次开发评估NGDC存档数据质量和进行更正的工具。 该项目旨在评估正在进行的地球物理数据的质量，并在数据一致的情况下，沿航迹和在两条航迹的关键交叉点进行校正。 这项研究的最终产品将是通用绘图工具的新功能，允许对交叉数据进行高级分析和自动处理NGDC文件，包括对可能的错误进行各种评估。
