IMA Workshop:
Dynamical Systems Techniques in Oceanography: Chaotic Advection
in Ocean Mesoscale Structure
May 7 - 9, 1998
Organizer: Chris Jones

Assessing the transport of fluid across such ocean structures
as the Gulf Stream, and the exchange of fluid between its constituent
parts, is essential for a clear understanding of the distribution
of fluid properties, such as temperature and salinity in the
Ocean. There have been significant advances recently in applying
the techniques of dynamical systems to numerical models and
assessing the significance of the fluid exchange resulting from
the mechanism known as "chaotic advection." A major hurdle has
been overcome in adapting the techniques previously developed
for periodic systems to aperiodic flows. However, to make effective
applications to realistic flows, and in particular numerical
models of real ocean situations, further devlopment is needed
as the output of the models extends over only finite times.
An efficient operational strategy for determining the extent
of chaotic mixing in realistic models promises important applications
in both oceanography and atmospheric sciences. A key to this
development is a close working relationship between applied
dynamicists and oceanographers. This workshop brought together
researchers from both areas and provided an opportunity to share
the recent advances in the different fields; it also provided
a forum for setting an agenda for future activity.
