Science Drivers and Fit within AON

(15.5 MB - PPT)

Jean-Claude Gascard, Université Pierre et Marie Curie

1. Autonomous and Lagrangian platforms in the context of AON. What science questions might these platforms contribute to, what critical measurements might they allow? How can they help measure change, and where do they fit within the existing suite of platforms and approaches (e.g. hydrography, moorings)?
2. Science drivers/key measurements:
   • Surface albedo
   • Ice thickness distribution
   • Persistent (year-round, multi year), full-depth, extensive measurements of watermass variability. Quantify broad changes in heat and freshwater storage, vertical stratification.
   • Long-term characterization of watermass and velocity structure across key frontal regions, slope-shelf interfaces.

Current state of the technology

Introduced and moderated by Craig Lee

1. What's working today, and how is it used? What are the major technological and development hurdles?

Discussion

(40 K - PPT)

Moderated by Lee and Gascard

1. How could these platforms be exploited to track, understand, and ultimately forecast arctic change? Are they appropriate tools for this task? How might they be employed? How will these platforms complement conventional approaches and technologies?
2. How should these technologies be adapted in response to the changing Arctic? Specifically, how might these platforms and approaches be changed to compensate for and exploit changes in arctic ice cover?
3. Identify technological challenges and development goals for enhancing the utility of autonomous Lagrangian platforms in the Arctic. Identify political and international coordination issues that will need to be addressed. How would the resulting systems fit within the larger scheme of arctic observing?

Recommendations and Next Steps:

Moderated by Craig Lee and Jean-Claude Gascard

1. What are immediate, mid- and long-term strategies to improve observational system design?
2. What specific efforts should be directed toward developing autonomous and Lagrangian systems and/or supporting technologies to provide long-term operation in the changing Arctic?
3. Discussion of workshop product(s), next steps, and writing assignments.
