The South American Meridional B-Field Array collects and analyzes data from a low-latitude meridional array of magnetometers along the coast of Chile and Antarctica. It includes five magnetometer sites approximately along the 0° geomagnetic longitude and ranging from -5° to -48° geomagnetic latitude. The sites are located at Los Cerrillos, Chile, Osorno, Chile, and at the O’Higgins, Escudero and Palmer research stations on the islands of the Antarctic Region.
