A radar experiment was conducted on 18 August 1978 at Kwajalein Atoll, Marshall Islands, to investigate the spatial relationship of 1-m equatorial spread-F irregularities to plasma bubbles localized depletions in F-layer plasma density. East-west scans were made with ALTAIR, an incoherent-scatter radar, to spatially map 1 the backscatter produced by field-aligned irregularities, and 2 the electron-density distribution of the background F layer. Plasma bubbles were spatially mapped for the first time with an incoherent-scatter radar. By assuming invariance along the magnetic field lines over distances of less than 100 km, we show that 1-m field-aligned irregularities are directly related to plasma bubbles. Author
