Breakout Sessions
October 14: Broad vision on crosscutting science themes
Develop a vision for each of the three topics listed below (one per breakout group) across 5 years into the future. Include short-, middle-, and long-term goals. Working Groups should define the ideal models to realize the modeling goals.
Breakout 14.1: Delta morphodynamics: coupling fluvial, coastal, marine processes and human influences on large deltas
Facilitator & Scribe: Andrew Ashton/Doug Edmonds
River deltas vary significantly in their ecological function, resilience to perturbations, and the stratigraphy of their deposits. Their natural dynamics feature tight couplings between rivers (floods, sediment fluxes, morphodynamics), wetlands (biologically-influenced floodplain aggradation, storm surge filtering), coastlines (cross-shore and alongshore sediment distribution from river mouths), and the marine environments (tides, waves, storms, delta progradation). In addition, in recent centuries humans have been significantly altering subsidence rates, fluvial and coastal morphodynamics, and terrestrial sediment delivery.
Charge: This group is challenged to design a delta modeling system that will allow us to better understand delta behavior and predict delta morphodynamic behavior in response to relevant forcing scenarios. What model components and couplings are most needed to address how deltas evolve, and how their fates and behaviors depend on the pattern of human land use and manipulations? Which processes/model couplings would provide the most utility to the community?
Breakout 14.2: Couplings between physical, biological and human processes in earth surface & ocean dynamics
Facilitator & Scribe: Dylan McNamara/Laura Moore
Two-way interactions between ecosystem and morphological evolution help steer landscape change in most of the environments on Earth, and two-way couplings between human actions and environmental change are becoming an increasingly important as human populations and technology expand and the climate changes. Biological-physical couplings are incorporated in some Earth-surface process modeling in recent years, but couplings between human and ‘natural’ components of the environment are still rare.
Charge: What model components and couplings are most needed to address the dynamics of environments in which physical, biological, and/or human influences are combined? Which processes/model couplings would provide the most utility to the community?
Breakout 14.3: Landscapes into Rock
Facilitator & Scribe: Peter Burgess/Rick Sarg
This continuation of the source-to-sink theme focuses on developing an enhanced ability to invert stratigraphy in terms of forcing mechanisms. Encoded in stratigraphy (we presume) is information about the landscapes of the source terrain. To understand that encoding we need a description of transformations from ‘upstream’ dynamics and surface sediment flux to preserved stratigraphy. This break-out group will address the problem of the interactions among erosional and depositional landscapes, sediment routing systems, and the building of stratigraphy. By modeling these interactions across the critical interface of the Earth’s surface, we want gain a better understanding of the dynamics of the coupled systems driving exhumation, erosion, transport and deposition of sediment.
Charge: This group is challenged to design a source terrain to sediment basin modeling system that would allow us to better invert the stratigraphic record for the dynamics of the coupled systems driving exhumation, erosion, transport, and deposition of sediment. The modeling system should be designed to answer some or all of the following questions: What can foreland basin stratigraphy tell us about geodynamic boundary conditions, climatic forcing, and autogenic processes in the source terrain? Under what circumstances do emergent dynamics in the coupled land-ocean sedimentary system erase or overwrite the signals from climatic and tectonic events, and under what circumstances do those signals become part of the rock record? How do the answers to these questions differ among the various types of sedimentary basins?
October 15: Action plans on crosscutting science themes
Define action plans to complete the models defined on October 14. Specifications should be as practical and specific as possible, listing what models are available, open-source, and componentized. The report from each group should contain a work plan giving an actual workflow to completion.
Breakout 15.1: Delta morphodynamics: coupling fluvial, coastal, marine processes and human influences on large deltas
Facilitator & Scribe: Andrew Ashton/Doug Edmonds
Breakout 15.2: Couplings between physical, biological and human processes in earth surface & ocean dynamics
Facilitator & Scribe: Dylan McNamara/Laura Moore
Breakout 15.3: Landscapes into Rock
Facilitator & Scribe: Peter Burgess/Rick Sarg
October 16: Vision & action plans on CSDMS services: communication, education and cyberinfrastructure
Community input is solicited on the services that CSDMS should provide over the 5 years into the future. The groups are charged to provide input on the vision as well as nuts and bolts implementation strategies. A report from each group should contain a work plan giving an actual workflow to completion.
Breakout 16.1: Strategies for Improving CSDMS Communication and Community
Facilitator & Scribe: Ben Sheets/Cristen Torrey
Community input and involvement are essential to the success of CSDMS. Now that we are three years into the CSDMS project, we’d like to take stock of how our community currently functions and develop plans for the future. Community participation has been promoted mainly through CSDMS workshops, individual member visits to the Integration Facility (IF), and town halls and sessions at major meetings. The CSDMS website currently hosts model, data, and educational repositories, in addition to offering powerful wiki functionality. We can track community involvement through contributions to and downloads of various CSDMS products and resources. In addition to being a repository for model code and metadata, CSDMS provides technical support for model developers, a new tool for model coupling (CMT), and supercomputer access.
Charge: This breakout group should discuss ideas for CSDMS community input and involvement over the next 5 years. The group should identify the types of social and technical changes (either new policies or software tools) that are needed to achieve this vision. The group should produce a written workplan summarizing current challenges, action items, and metrics for success. Specifically, are there specific ways in which our membership base should expand and connect with other existing communities? How well does our face-to-face meeting approach serve the needs of our current members, and how can we better sustain momentum (particularly on proposal development and other working group activities) following these meetings? How can the website more effectively meet the needs of our membership? Should CSDMS implement more remote collaboration and social networking tools (e.g., blogs or discussion boards) to help promote contribution to and use of CSDMS resources? How do we prioritize the types of help systems (and concomitant person-hours) that need to be put into place to serve our diverse user community?
Breakout 16.2: Education and knowledge transfer strategies
Facilitator & Scribe: Dave Budd/Zac Flamig
CSDMS strives to empower a broad community of earth surface process scientists with computing tools and knowledge from interlinked fields. New insights in surface processes that results from model simulations can be shared with a wide community of non-specialists through web-based educational products; e.g. documented model simulations, or greatly simplified models allowing exploration of the model domains.
Charge: Breakout group should tackle both a large vision oriented discussion; define our strategy for education over the next 5 years; and define an action plan to complete new educational tools and products. How does this CSDMS knowledge and products better penetrate into society? Which of the ‘earth science, ocean science or environmental literacy big ideas’ should the CSDMS community adopt? Identify critical linkages to science education platforms related to CSDMS; e.g. develop animations for nature and science museums, or for visitor centers of national parks? A CSDMS model-coupling tool has been developed — how broad an audience is appropriate for this application interface, or should new dedicated tools be developed for beginner modelers? The specifications should be as practical and specific as possible. Group report should contain a workflow to completion.
Breakout 16.3: CSDMS Cyberinfrastructure: Expanding our Reach
Facilitator & Scribe: Eric Hutton/Brendon Hall
Charge: Breakout group should discuss goals for advancing the CSDMS architecture over the next 5 years. Specifically, the group should prioritize among the new initiatives discussed during the workshop and produce a written work plan summarizing current challenges, action items, and metrics for success.
- CSDMS modules and models must be tested against data. How should we prioritize efforts to link to existing community data centers (e.g., adding web data server functionality to the CSDMS Modeling Tool (CMT))?
- What mechanisms would facilitate the componentization, testing and intercomparison of models by our working groups?
- CMT allows for the coupling of models that have already been componentized. Should we invest in a new tool, a “Component Builder,” that allows users to develop and compile code on the CSDMS HPCC, while adopting CSDMS protocols?
- As we gain new models, how should we connect to existing standards for the issues of ontology and semantics (e.g. NetCDF Climate and Forecast Metadata Convention, Earth System Grid Ontology)?
- CSDMS compliant, source code must be in one of the supported languages: fortran, c, c++, java, and python. Are there other languages we should consider supporting?
- The CSDMS supercomputer has already seen heavy usage. Are there issues we need to consider down the road as we connect to the TeraGrid?
