Airborne geophysical survey: Bering Glacier and Icy Bay 1° x 3° Quadrangles

Aeromagnetic and aeroradiometric data were collected along flight lines by
instruments in an aircraft that recorded magnetic-field and radiometric
values and locations. The magnetic data set presents latitude, longitude,
altitude, and magnetic-field values. Geologic symbols or codes are also
included. The geologic symbols were picked from surficial geologic maps.
The radiometric data set presents latitude, longitude, altitude, geologic
symbols or codes, apparent Uranium (Bismuth 214), Thorium (Thallium 208),
and Potassium (K 40), the element ratios, and ancillary information.

本数据集包含沿飞行航线由机载仪器采集的航空磁测与航空放射性测量数据，仪器同步记录磁场强度、放射性参数及测点坐标。其中磁测数据集涵盖纬度、经度、海拔高度及磁场强度值，同时附带地质符号或编码，该类地质符号源自地表地质图。放射性测量数据集则包含纬度、经度、海拔高度、地质符号或编码、视铀（铋214）、钍（铊208）、钾（K-40）、元素比值及辅助信息。
