Operation of the Goose Bay radar began on October 11, 1983. Since that time collaborative measurements have been made with both the Sondre Stromfjord and Millstone Hill incoherent scatter radars, with the HILAT satellite, and with the Air Force Geophysics Laboratory Airborne Geophysical Observatory. In addition, an extensive set of noncollaborative measurements have been obtained. From this base of observation several papers have been written and submitted for publication and several studies have been initiated but not, as yet, reached the publication stage. These efforts include an examination of high latitude F-region irregularties in the afternoon and late evening local time sectors, an attempt to use the HF radar data to study the two-dimensional structure of irregularity drifts, a detailed study of plasma conditions and irregularity characteristics in the vicinity of the dayside cleft, attempts to compare E- and F-region irregularity drifts with plasma drift measurements obtained with the Sondre Stromfjord and Millstone Hill incoherent scatter radars, and some preliminary observations of seasonal depencences in the diurnal formation of high latitude F-region irregularities. Keywords include: Radar; HF; Electron; Density; Irregularities; E- and F-regions; Ionospheric; Oscillatory; and quasistationary.
