proposal for such a program, which would start on 1 October 1977, when the
present PTP would terminate. A subsequent planning discussion was held between
Goldberg, Duce and Dr. Thomas Church, NSF/IDOE program manager, at the Joint
Oceanographic Assembly in Edinburgh in September, 1976.
To develop the strongest possible proposal, it was necessary to publicize SEAREX as widely as possible in the scientific community.

In addition

to individual contacts and letters, an advertisement soliciting Tetters of
intent from the scientific community was published in Science in early November, 1976.

Individuals interested in participating in SEAREX were asked to

submit a five-page letter outlining their proposed program to an interim
Scientific Advisory Committee.

This Advisory Committee was composed of

~~

Dr. John Winchester, Florida State University; Dr. Karl Turekian, Yale
University; Dr. Thomas Church, University of Delaware; Dr. Robert Duce,
University of Rhode Island; Dr. Edward Goldberg, Scripps Institute of
Oceanography; and Or. Clair Patterson, California Institute of Technology.
Twenty three letter proposals were submitted and the Scientific Advisory

Committee selected seven of these as being of high scientific quality and.
most compatible with the stated objectives of SEAREX.

The investigators

submitting these seven letter proposals met on January 7-8, 1977, at Scripns
to develop the SEAREX proposal.

At this meeting an important research area

None of the letters of intention reviewed by the

interim SEAREX Advisory Committee contained proposals to do these measurements.

Karl K. Turekian volunteered to make these important measurements

during the first week of January, 1977, and with the approval of the Advisory
Committee an eighth investigator was included in the final SEAREX proposal.
