Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Metadata Last Checked: January 27, 2026 | Last Modified: 1997-11-14T00:00:00.000+00:00
Data were gathered by the R/V Marion Dufresne in May and June of 1992 over the Mascarene Ridge in the Indian Ocean on cruise MD72/MASCAFLUX. Heat flow measurements for 96 in-situ readings including both thermal conductivity and thermal gradient were recorded along two profiles perpendicular to the mascarene ridge. NCEI also archives bathymetric and magnetic data from the cruise. Data correspond to: Bonneville, et al., EOS, 73, 43, p. 542, 1992. and Bonneville, A., R.P. Von Herzen and F. Lucazeau, Heat flow over Reunion hot spot track: additional evidence for thermal rejuvenation of oceanic lithosphere, Journal of Geophysical Research, 1995. The data were sent to NCEI by Dr. Alain Bonneville for distribution.
