                                  SUMMARY

     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.

     NGDC also archives bathymetric and magnetic data from the cruise
     in the GEODAS geophysical data management system.

     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 NGDC by Dr. Alain Bonneville for
     distribution.

                                AVAILABILITY

     Data are available for free download from NGDC's WWW server.
