Description:
In 1978, the first Keystone Conference addressed the scientific problems
of sediment transport in a high energy flow such as the Western
Boundary Undercurrent. Sedimentologists, physical oceanographers, geologists,
optical oceanographers, biologists, and ocean engineers planned
a program called the High Energy Benthic Boundary Layer Experiment
(HEBBLE) to measure ocean floor bed-forms, sediment properties, turbulent
flow structure, suspended sediment concentrations and fluxes, mixed
layer thickness, outer scale velocity and horizontal gradients of density
in a carefully surveyed site yet to be selected. While measurements
were suggested, specific instruments were not identified to implement
them. It was encouraging that the scientists participating in the
first HEBBLE Conference wanted to continue to plan a multi-disciplinary
experiment.
Because of the Jet Propulsion Laboratory's experience in management
of planetary science experiments, autonomous instrumentation, image processing
and data handling, we invited them to develop our experimental
plan. Conferences were held in September at Woods Hole and November,
1978 at JPL to develop the instrumental ensemble. JPL involvement was
concentrated on the extended deployment part of HEBBLE: the 6-month
experiment. The March 20-23, 1979 conference brought JPL engineers and
managers, HEBBLE scientists and PI's, ONR and NASA program managers together
in Keystone, Colorado for presentation and discussion of the JPL
program plan. This report summarizes the conference and includes
reports by subcommittees of the conference on measurements and data
sampling.
