This project will extend an existing chain of ground-based magnetometers (SAMBA = South American Meridional B-field Array) into Antarctica. Two additional magnetometers will be emplaced, one at Palmer, a year-round U.S. station, and the other at Patriot Hills, a more remote Chilean summer-only station. The installation at Patriot Hills will be done with the logistical support of the Chilean Antarctic Institute. The scientific goals of the expanded array are to increase the spatial resolution of existing cusp-to-cusp chains, to extend the number of conjugate pairs of stations between the northern and southern hemisphere thus increasing the size of the inner magnetospheric region that can be remotely monitored from the two hemispheres, and to establish an auroral latitude station conjugate to the Canadian Poste de la Baleine station in order to study conjugate differences of substorms and general auroral activity.

该项目将把现有的一系列地面磁力仪（桑巴舞=南美洲子午线B场阵列）延伸到南极洲。 另外两个磁力计将被安置，一个在帕尔默，一个全年的美国站，另一个在爱国者山，一个更偏远的智利夏季站。 将在智利南极研究所的后勤支持下在爱国者山安装。扩大阵列的科学目标是提高现有尖点到尖点链的空间分辨率，增加北方和南半球之间的共轭台站对的数目，从而增加可从两个半球进行远程监测的内磁层区域的面积，建立一个与加拿大Poste de la Baleine站共轭的极光纬度站，以研究亚暴和一般极光活动的共轭差异。
