Abstract : One of a series of 27 (NELC TD 391-417) presenting measurements of the relative phase difference of signals from various paris of Omega stations as observed at several monitoring sites around the world. The data documented in the report were obtained during a cruise of the British hydrographic survey ship HMS VIDAL during the summer of 1966. Previous data from similar voyages have been documented in NEL Technical Report 1350, OMEGA IN THE ATLANTIC, which describes the results of the Omega monitoring during oceanographic survey Project NAVADO of 1963-1965.
