below the EUC core, and a vertical profile of diapycnal
vertical velocity (turbulent flux) that reverses sign from
upward flux to downward flux at the EUC core.
Numerical models agree on the upwelling but not on
the downwelling. How do we test this? The dilemma is
that subtle aspects of models such as the vertical
velocity depend critically on turbulence mixing param-
eterizations. Models alone, so long as they depend on
the parameterizations of unknown quantities, cannot
solve all problems of equatorial circulation. So the need
for observations is as necessary now as during the IGY.
Much remains to be done; the importance of mentoring
new graduate students remains as critical as ever, and
the examples set by John Knauss are lessons well
learned.

Mark Twain has been quoted as saying, "Adam and
Eve had many advantages, but the principal one was
that they escaped teething." Graduate students will
never escape teething as they learn to become indepen-
dent scientists, but John showed that it could be a
pleasurable, exciting experience for which I close this
observer's perspective on the equatorial ocean circula-
tion with a simple statement of thanks.

John Atkinson Knauss is a person who has made a
difference in what today's oceanography is all about.
Born in 1925 in Detroit, he was commissioned in the
Navy program in meteorology and received his B.S. in
meteorology from Massachusetts Institute of Technology
in 1946. These were the war years, and brought John to
the Navy Electronics Laboratory in San Diego for two
years, and then on to Washington where he was one of
the young men working with Roger Revelle to establish
the glorious traditions of the Office of Naval Research
(ONR). There John, Art Maxwell and Gordon Lill
invented the Albatross Award which they promptly
awarded to themselves for thinking of it.

In the decade of the 1950s John alternated between
being a Scripps student and an ONR Project Officer;
while a graduate student he once served as Acting
Director of Scripps while Roger Revelle was out at sea.
In 1959 John submitted his dissertation on The Cromwell
Current, a discussion of the unique dynamics of the
equatorial undercurrent.

In 1962 John left Scripps to become the founding Dean
(later Provost) of the Graduate School of Oceanography
at the University of Rhode Island. The ocean community
owes John a vote of thanks for having established one of

the leading centers of ocean research.

John was member of the Stratton Commission 1967-
1968. One of the Commission accomplishments was to
found the National Oceanic and Atmospheric
Administration (NOAA), and some years later (in the
tradition of the Albatross Award) John was appointed as
Administrator of NOAA from 1989 - 1992. He served on
various National Academy committees and recently
served a term as President of the American Geophysical
Union.

John is always ready to help in any capacity to further
oceanography. He can be very persuasive. I vaguely
remember a very noisy party by our graduate students to
celebrate some oceanographic event; the police showed
up and asked John and others to come along. Before they
reached the police station, John had persuaded the offi-
cers that oceanography was a wonderful field, and to
turn around and deliver them back to go on with their
celebration.
