2014-15 Autonomous Adaptive Ocean
Sensing Networks These systems will:
• Be capable of coordinating a suite
of marine autonomous systems
• Enable the gathering of data from
the ocean over periods of several
months
• Able to track and sample dynamic
features

• A network management system that allows the
specification of a formation of ASVs that will be able to track a dynamic feature
• Be able to exploit other instruments and platforms that are
used by NERC such as seabed landers, autonomous underwater vehicles and
submarine gliders
• A transparent decision-making
systems tested in a simulation environment
• Provide an insight with respect to the
robustness of the communication systems

Autonomous Adaptive Ocean Sensing Networks
In September 2014 NERC in partnership with Innovate UK and Dstl
launched a £1.5m competition for the development of novel Adaptive
Autonomous Ocean Sampling Networks (AAOSN). Over 18 months
two UK consortia have developed systems capable of coordinating a
suite of marine autonomous vehicles to gather data on dynamic
features. The Breakfast Club meeting will see presentations from the
lead organisations of both consortia, Seebyte Ltd and University of
Exeter as they provide a final status report on the products they
have developed under this funded programme. This programme will
include demonstrations of the products and opportunities for Q&A
with the inventors.

Conclusions
• Software can help coordination
• Significant reduction in pilot load
• Human oversight needs to remain
• Practical piloting issues are complex
– Limitations on speed are a problem
– Cost of communication need to be considered

• No human intervention
• Just specify the value of the contour or maximum or
minimum

Tracking an ocean front
• Unlike ocean bathymetry ocean fronts are dynamic

• If you want to survey a front simply tracking a contour
doesn’t give you a lot of information
• We would like to have the structure of the front
• Use two vehicles
• One to map the front
• One to find the structure

Tracking a tracer release
• Mapping the ‘edge’ of a tracer release (e.g. an oil spill)

• Two experiments
• Release particles into Met O model
• Southern North Sea – little advection, mainly diffusion
• Irish sea front – a lot of advection

Finding a Maximum
• We can modify the algorithm to find maxima
• Move from one contour to the next
• No derivative information just current measurement

Next Steps • Embed the algorithm on the vehicle
• Expand to non-surface vehicles
• Autosub and other AUVs
• Gliders
• Incorporate Bayesian Learning
