Appendix C – Breakout Session Challenge Questions
The following challenge questions were provided to workshop participants in advance of the
workshop to frame the discussion towards tangible recommendations. NOTE: Prior to the
lunch break on the first day of the workshop the group agreed to remain as a single discussion
group to address the challenge questions.
Background:
NOAA’s ocean observation and mapping requirements include near shore, shallow
water (less than 10 meters). Traditional shipboard observations may not be possible or
effective in these areas, and small boat survey operations may be laborious or unsafe. NOAA is
investigating the feasibility of using unmanned systems, particularly Autonomous Surface
Vehicles (ASVs), to meet these shallow water requirements. While the initial scope of the
investigation is focused on shallow water, the lessons learned are expected to inform decisions
regarding the broader application of ASVs.
To answer the question of feasibility NOAA and other users must determine if ASVs can provide
one or more of the following benefits:
•
Reduce the efficiency of data acquisition, includes time, personnel, and operating costs.
•
Improve the quality of the data acquired
•
Improve the safety of survey operations
•
Provide data that is beneficial, but otherwise unattainable
User Needs:
In terms of both Mapping and Water Quality Monitoring, please address as many
of the following points as possible.
Challenge Questions
1. Describe acceptable physical & technical characteristics of the ASV. Include a) Physical
dimension and weight, b) Energy source (battery or fuel type) and propulsion system, c)
Endurance at survey speed, and d) Charging time.
2. Describe acceptable physical and technical characteristics of any required shipboard or
shore-side equipment, such as operator console, battery charging unit, or communication
interface. Include a) Physical dimensions, b) Power requirements, and c) Cabling requirements.
3. Describe desired ASV payload capabilities. Include a) Positioning and motion systems, b)
Data logging and telemetry capabilities, c) Standard payload packages, d) Interfaces or tools for
user-integrated payloads, and e) Maximum size, weight, and energy capacities.
4. Describe acceptable ASV launch and recovery requirements. Can it be operated from shore,
small boats, and ships? How many people are need for safe launch and recovery? Is a Launch
and Recovery System (LARS) necessary or an available option?
