Abstract:

The continuation of the Polar work originally proposed to the ONR in 1990 for this proposal had to be curtailed after the cancellation of the Barents Sea cruise in 1990 and after the P.I. was denied space on the trans-Polar expedition during the summer of 1991. Instead, after consultation with the ONR program manager the P.I. participated in a cruise designed to use trace elements to survey the hydrothermal plumes generated by sea-floor hydrothermal activity between 9 deg and 11 deg N on the East Pacific Rise. The P.I.s participation in this cruise was designed to determine the magnitude and variability of dissolved Al enrichment the hydrothermal plumes which result from the mixing of hydrothermal vent fluids with the overlying sea water.
