MAVA 11 Magnetic dataset of Vavilov Volcano

MAVA 11 Magnetic dataset of Vavilov VolcanoShipborne magnetic data of Vavilov volcano (VAV)were also collected during the MAVA11 cruise by using a SeaSpy Marine Magnetics magnetometer towed 180 m astern the ship. Positioning of the tow fish was estimated by applying a synchronous GPS layback correction. We conducted the geophysical investigation in two distinct surveys: i) a larger one covering the entire VAV edifice and partly also its basin using a set of lines spaced 1500 m ; ii) a second high resolution survey focused on VAV carried out using a set of lines spaced about 1000 m.瓦维洛夫火山磁学数据集（MAVA 11） 本数据集包含MAVA11航次期间采集的瓦维洛夫火山（Vavilov Volcano，简称VAV）船载磁力测量数据：数据采集时采用拖曳于船尾180米处的SeaSpy Marine Magnetics海洋磁力仪。拖曳式磁力仪探头（tow fish）的位置通过同步GPS偏移校正算法进行估算。本次地球物理勘探分为两个独立勘测阶段：i) 大尺度勘测：覆盖完整的VAV火山山体及其部分周边盆地，测线布设间距为1500米；ii) 高分辨率勘测：聚焦瓦维洛夫火山区域，测线布设间距约为1000米。
