The idea that the cumulative action of centimeter-scale mixing
affects the ocean's largest scales caught my attention in
graduate school and continues to guide my research. Evolving
technology now enables us to put the mixing into the context of
the meter-to-kilometer-scale processes directly producing it,
such as internal waves, bottom and surface boundary layers,
thermohaline staircases and intrusions,
and hydraulic responses to flow constrictions. Because large-scale
models, particularly coupled climate models, have grid scales
vastly larger than those of the mixing and even of the
intermediate-scale processes producing it,
I always try to guide our work toward parameterizations that
can be used in these models.
To study mixing and the small-scale physics of the ocean we
conduct experiments at sea using a mix of instruments,
some of which we design and build. To do this I support
a core group consisting of Jack Miller, who is co-PI on all
my projects and has a B.S. in electrical engineering and a M.S.
in computer science, Dave Winkel, a former student who has a
Ph.D. in oceanography, Steve Bayer, who has the same degrees
as Jack, and Earl Krause, who has a B.S. in oceanography. In
addition, I usually have several graduate students and often work
with other oceanographers in the Ocean Physics Department as
well as in other institutions. The National Science Foundation,
the Office of Naval Research, and Washington State Sea Grant
support our work. I am a tenured professor in the School of
Oceanography and a staff scientist at the Applied Physics
Laboratory where my group works.
