4.
To identify the natural or anthropogenic origin of Pb in marine
aerosols by means of Pb isotope tracers and mass balance relationships of present atmospheric input. fluxes with prehistoric sediment
output fluxes.
5.
To investigate in detail, using classical as well as sophisticated
laser fluorescence techniques, the distribution and exchange between
the particulate and vapor phase of organics and of the relatively
volatile heavy metals such as Pb, Cd, Zn, Se, Sb, As, Cu, Hg, and
.
Ag.
6.
To investigate bubble surface area and volume spectra in the sea and
the relative importance of single bubbles and bubble rafts as
sources of atmospheric spray and sea salt particles, both as a
function of wind speed.
We propose to undertake this sea/air exchange research program with a
group of twelve senior co-investigators from eight institutions:
Dr. R. Chesselet, CFR/CNRS, France
Dr. R. Duce, University of Rhode Island
Dr. J. Fasching, University of Rhode Island
Dr. W. Fitzgerald, University of Connecticut
Dr. R. Gagosian, Woods Hole Oceanographic Institution
Dr. C. Giam, Texas A & M University
Dr. E. Goldberg, Scripps Institute of Oceanography
Dr. E. Kraus, University of Miami
Dr. C. Patterson, California Institute of Technology
Dr. J. Prospero, University of Miami
Dr. K. Turekian, Yale University
Dr. QO. Zafiriou, Woods Hole Oceanographic Institution
