workshop quickly uncovered our almost total ignorance of the fluxes of trace
metals and virtually all organic substances between the atmosphere and the
ocean, the mechanisms of exchange of these substances across the sea/air
interface, and the great difficulty in distinguishing between natural and
pollution sources for many of the trace substances found in marine air.
There was a general concensus that a major coordinated research program investigating these sea/air exchange problems should be undertaken.
This
proposal for a sea/air exchange (SEAREX) program represents an initial step
in that direction.
The purpose of this overview section is to put the entire SEAREX
proposal into perspective, presenting our overall objectives, how the proposal
was developed, the planned scope of SEAREX over its presently conceived five
year duration, and a more detailed description of the first two year's work.
Particular attention will be given to the need and rationale for common
facilities and experiments.
Subsequent sections deal with the investigations
of the individual research groups in much more detail and the final section
considers the management and field support functions in SEAREX.

OBJECTIVES OF SEAREX
The general objectives of the SEAREX Program are:
|.
The quantitative measurement of atmospheric fluxes of selected
heavy metals {e.g., Pb, Cd, Zn, Se, Sb, As, Cu, Ha, Ag),
2105,
and its daughter 2105, and organic compounds such as the man-
associated PCB, DDT, polynuclear aromatic and aliphatic hydrocarbons,
phthalate plasticizers and the natural occurringsteroidal and
terpenoid hydrocarbons, fatty acids and alcohols, low molecular
