Acoustic Backscatter image data, Reykjanes Ridge, Langseth cruise MGL1309 (2013, investigators Fernando Martinez and Richard Hey)

This processed acoustic backscatter data was extracted from the R/V Langseth Kongsberg EM122 multibeam files and processed using MB-System software (Caress and Chayes, 2008) including corrections for angular equalization. The data was gridded using GMT-5 software (Wessel et al., 2013) in 0.0005 x 0.00025 degree cells in longitude and latitude. The data file is in PDF format. It is cited in Martinez and Hey, 2017, and was generated as part of the project called Test Between Thermal and Tectonic Hypotheses for North Atlantic Seafloor Spreading Geometry Reorganization. Funding was provided by NSF award OCE11-54071.

本数据集为经处理的声学背散射数据，提取自朗塞特号研究船（R/V Langseth）的康士伯EM122（Kongsberg EM122）多波束文件，并通过MB-System软件（Caress与Chayes，2008）完成处理，其中包含角度均衡校正步骤。本数据集采用GMT-5软件（Wessel等，2013）进行网格化处理，格网单元的经纬度分辨率为0.0005×0.00025度。本数据集文件采用PDF格式存储。该数据集已被Martinez与Hey（2017）引用，其生成工作隶属于“北大西洋海底扩张几何重组的热学与构造假说检验（Test Between Thermal and Tectonic Hypotheses for North Atlantic Seafloor Spreading Geometry Reorganization）”项目。本研究获得美国国家科学基金会（National Science Foundation，NSF）资助项目OCE11-54071的经费支持。
