Goals
Where have we been?
Where are we going?
How are we going to get there?
4
Initial Goals in 1993
Mission Monitor long-term trends and
assess the importance of episodic events within
the ubiquitous ridge and swale topography on the
inner shelf of the Mid-Atlantic Bight. To provide
unlimited power and pipe real-time data to
shore.
5
Succeses High resolution time series during
summer upwelling High resolution data sets ideal
for validating 1-D models of sediment
transport Variability in coastal optical
properties
Goal is to move into preoperational status, where
it does not require a science team for
operation, operations being transferred to staff

Initial Goals in 1998
Mission Improving nowcast skill via data
assimilation, improve forecast skill via
boundary forcing. Characterizing the
spatial/temporal variability in the inherent
optical properties. Use these improved
modeling/observations for rapid environmental
assessment of coastal frontal features.

Ensemble Forecasts
Thermistor

• In an observationally rich
• environment, ensemble forecasts
• can be compared to real-time data
• to assess which model is closer to reality
• and try to understand why.

12
Use models to effectively sample frontal
boundaries in a nested grid of remote sensing
imagery

The Collaboratory Experience
Rich scientific environment, where groups can
leverage off each other
A training ground for operational oceanography
In the present form has been maintained for 1
month and is heavily dependent on human
involvement
Observationally-rich allowing for model
improvement

Initial Goals
Mission Objectives. What is the mean along-shelf
transport and what is the physical forcing of
primary productivity and biogeochemical fluxes?
What is the quantitative significance of
episodic events in the annual productivity budget
of the MAB? How does the coastal circulation
determine bulk residence time of organic material
transported or produced on the shelf? How
important are the localized bathymetric features
in driving both surface and subsurface
convergence fields and are they the major
mechanism for persistent offshore biological
fronts?
