Magnetic anomaly data compilation, East Pacific Rise, 12N-16N (2011, investigator Marie-Helene Cormier)

Magnetic anomaly data compiled for the East Pacific Rise between 12N-16N. The compilation is based upon 70 shipboard magnetic surveys. Over 5,000 track crossovers were analysed and processing was done to minimise the crossover least squares errors. The data was gridded at an interval of 0.5 arc minute (about 900 m) using a continuous curvature spline algorithm. The data set is cited in Cormier et al., 2011. The data file is in netCDF:GMT grid format and was generated as part of the project called Kinematic and Gravity Study of the Northern East Pacific Rise and Its Flanks: Propagating Ridges and Melt Supply. Funding was provided by NSF award OCE96-29903.

本数据集为东太平洋海隆（East Pacific Rise）12°N至16°N区间的磁异常数据汇编成果。该汇编基于70次船载磁测工作所得数据，共分析了5000余条测线交叉点，并通过数据处理将交叉点最小二乘误差降至最低。研究采用连续曲率样条算法，将数据网格化至0.5角分（约900米）的格网间距。本数据集已在Cormier等（2011）的研究中被引用。数据文件采用netCDF:GMT格网格式，其生成依托于名为‘北东太平洋海隆及其侧翼的运动学与重力研究：扩张脊与熔体供给’的科研项目。本项目受美国国家科学基金会（NSF）资助，资助编号为OCE96-29903。
