SCOTS Workshop: Cabled Observatory Initiatives and Science Synergies

Join us at the SCOTS Workshop in Portsmouth, VA from August 26-28, 2002 to discuss cabled observatories, their technological capabilities and challenges, and the science problems best addressed with a cabled approach. Explore synergistic opportunities with other observing systems and provide input for the SCOTS Report.

  1. NSF SCOTS Workshop Portsmouth, VA August 26-28, 2002 SCOTS SC: Scott Glenn (co-chair), Tommy Dickey (co-chair), Jim Bellingham, Yi Chao, Fred Duennebier, Ann Gargett, Dave Karl, Lauren Mullineax, Dave Musgrave, Clare Reimers, Don Wright, Mark Zumberge, Bob Weller (ex-officio) Alex Isern, Bill Fornes, Shelby Walker Pre-Workshop Meeting in Belmont, MD Portsmouth Workshop ~ 50 Participants Subdivided into science and technology WGs Theme of science synergies emerged

  2. Workshop Goals Assist in planning for NSF observatories initiatives Define science problems best addressed with cabled approach Describe technological capabilities and challenges Suggest sensors, sampling strategies, array designs, and possible locations for science problems relevant to cabled approach Identify synergistic opportunities w.r.t. science, technology, and other non-cabled observing systems (coastal, open ocean) Provide community input for SCOTS Report

  3. Participants’ Feedback and Input Provide replies to workshop discussion questions by Tuesday afternoon 5pm to Bill or Shelby Give comments on SCOTS Report Introduction Give Websites and references for report to Bill Presented several Posters: Electr. versions of posters to Bill Asked for more input midway through Workshop/Discussed in Plenary Asked to give Input and Feedback for SCOTS report based on workshop discussions Final SCOTS Report Due November 1, 2002

  4. Workshop Plan - Tuesday Discuss generic cabled observatory/Panel discussion (Technology) (Tues. 9:00-10:15am) Introduction to 6 general science topics by SCOTS SC members [6 themes generally parallel Millenium Report; given on SCOTS website later] (Tues. 10:30-noon) Breakout I : Science themes & questions: Prioritize science (Tues. 1:00-3:30) Plenary: Review Breakout I discussions/priorities (Tues. 3:45-5:30pm) SCOTS Workshop Portsmouth, VA August 26-28, 2002

  5. Workshop Plan - Wednesday Questions from Day 1/Intros. to Breakout Sessions II and III (Wed. 8:30-8:45am) Presentation by Technology Breakout Group (led by Jim B.) (Wed. 8:45-9:00am) Breakout II: Impact and feasibility: Science & technologies (Wed. 9:00-10:30am) Breakout III: Location and implementation of cabled observ. (Wed. 10:45-noon/working lunch) SCOTS Workshop Portsmouth, VA August 26-28, 2002

  6. Introduction to Session I: Science questions requiring or best served by cable approach Identify science problems w.r.t. cabled approach Determine impact of cabled approach on science problems of interest and interdisciplinary synergies w.r.t. other observing system assets (e.g., coastal and open ocean) Discuss advantages and disadvantages of cabled approach vis a vis other sampling approaches as well as potential synergies Deliverables: * Listing of science problems best served by cable approach * Justification w.r.t. cable approach (3-4 sentences for each) * Definition of cable attributes that support science (e.g., bandwidth, power, vehicle support, etc.)

  7. Introduction to Session II: Description of technological capabilities required for science topics of Session I Based on yesterday’s discussions, Evaluate priority science vs. feasibility of making synergistic scientific advances considering available technologies. What variables and time and space sampling ranges are necessary for answering science questions? Provide specific cabled observatory attributes required for science problems outlined yesterday (e.g., how many nodes, what kinds and numbers of platforms, sampling rates, power, bandwidth) Recommend available sensors, platforms, vehicles, etc. for science problems outlined yesterday What sensors and technologies still require development to accomplish the science goals and objectives?

  8. Introduction to Session III: Location and implementation of cabled observatories Develop phased implementation plan for cabled observatory network with view toward interdisciplinarity and synergies Describe synergies with other envisioned observing systems Identify potential scientific and technological spinoffs (e.g., “oversampling” to enable optimal parameterization of high frequency/small scale processes) Identify optimal locations for top science problems

  9. Thursday SCOTS SC Meeting Agenda Review written input on Introduction and other sections of report (Scott and Tommy) Define structure of the outline of sections of SCOTS Report Base content on draft outline and abstract Follow the workshop topics discussed in Sessions I, II, and III Sections will address new issues raised during workshop The final page should summarize key synergetic aspectics for science topic. Length to be 5 pages (Follow Ann Gargett’s model for format/style)/Use side boxes for examples/illustrations Discuss timeline for completion of Report

  10. Thursday SC Meeting: Timeline for Completion of Report September 30, 2002: Drafts of sections and graphics for report to Tommy, Scott, et al. Most are in on time! We will work on editing at Scott’s this weekend. October 15, 2002: 1) Editing of report by Tommy and Scott and 2) submission of final graphics from SC to Alex October 15, 2002 Draft report sent to SCOTS SC for final comments October 23, 2002 SCOTS SC final comments and graphics subm. November 1, 2002: Submission of finished Report to Alex for external review (selected reviewers and community)

  13. Examples of Synergetic Science Topics:Unifying Themes Based on Prior DiscussionsExample themes that could be simultaneously addressed with a common cabled observing systemMax. Bang for the Buck!

  14. Examples of Synergetic Science Topics:Unifying Themes Based on Prior Discussions Magmatic and Tectonic Events: including hydrothemal vents, seafloor spreading, seismic events and generation of tsunamis (coastal processes connection), volcanic events, plume dynamics – particles, mixing, and transport, nutrient and carbon fluxes and budgets, turbulent mixing and biophysical interactions, fluids and life in ocean crust, ecosystem dynamics and biodiversity, etc,, etc.

  15. Examples of Synergetic Science Topics:Unifying Themes Based on Prior DiscussionsThese themes could be simultaneously addressed with a common cabled observing system(Max. Bang for the Buck) Bottom Boundary Layer: Turbulent mixing and biophysical interactions, sfc. and internal waves, vertical fluxes, sediment resuspension and transport, ripple formation and migration, benthic organisms and their response to physical events, bioturbation, pore water, seismic, storm and hurricane response, species succession, n processes, nutrient transport and carbon fluxes, primary production, biological colonization and succession, anoxia events, biological-mineral interactions, chemosynthetic production, carbon flux, diagenesis, etc., etc.

  16. Examples of Synergetic Science Topics:Unifying Themes Based on Prior Discussions Open Ocean Mesoscale Processes: general circulation, Rossby waves, internal and inertial waves, air-sea interaction, turbulent mixing and phytoplankton dynamics, nutrient and carbon fluxes and budgets (scalable to basin and global scale problems), ecosystem dynamics, succession, zooplankton and higher trophodynamics, population dynamics and fisheries, relation of eddy types and frequencies to ENSO and decadal oscillation phenemena.
