Airborne geophysical survey: Western Brooks Range

Aeromagnetic data were collected along flight lines by instruments in an aircraft that recorded magnetic-field intensity values and location. In surveys such as this one where the data were originally collected in digital form and not digitized from contour maps, the information we provide typically includes latitude, longitude, magnetic anomaly in nanoTeslas, and intermediate values used to derive the magnetic anomaly such as total magnetic field.航空磁测数据由航空器搭载的仪器沿飞行航线采集，同步记录磁场强度与定位坐标。 如本次磁测勘探，其数据最初即以数字形式采集而非从等值线图数字化所得，本数据集提供的信息通常涵盖纬度、经度、以纳特斯拉（nanoTeslas）为单位的磁异常值，以及用于推导磁异常的中间参数（如总磁场强度）。
