3. 2. Expectations about research data are evolving
1. New technologies create
more data
2. Funding agencies want
data management plans
3. Journals want links to
archived full datasets
4. Better attribution is enabled
by new metrics for data

4. 3. Grand challenges in experimental
geomorphology require data syntheses
reproducibility scalingautogenic vs. allogenic processes

6. We need SEN.
SEN’s goal is to integrate the efforts of sediment experimentalists and build
a knowledge base for guidance on best practices for data collection and
management, and to be the liaison to cyberinfrastructure and geoinformatics
communities.
7. The experimental life cycle
parallels the data life cycle.
SEN activities are designed to
help at each step.

SEN supports researchers
throughout the
data lifecycle
8. Three components of SEN
SEN-EC
Experimental
Collaboratories
• Facilitate collaboration
between experimental
laboratories
• Develop collaborative
infrastructure
• Broadcast experiments
• Distributed experiments
SEN-KB
Knowledge
Base
• Develop online resources
for experimental data
management
• SEN-Wiki
• Recruit datasets for
inclusion in online
repositories
SEN-ED
Education &
Data Standards
• Facilitate community
discussion of data
practices and standards
• Disseminate guidelines
• Provide training about data
management and sharing
9. Town Halls – to facilitate community discussion
2012: Surface Process Experiments –
A Community Discussion
2013: Building a Sediment
Experimentalist Network
2014: Publishing and Sharing
Earth Surface Data
SEN-ED
10. Workshops – to learn and experiment together
Dec 2012: End-User workshop
Experimental Stratigraphy (UT
Austin)
Aug 2013: Stratodynamics
(Nagasaki U.)
Nov 2014: Experimental Life
Cycle workshop (Utrecht U.)
SEN-ED
12. Proposed metadata profile for experiments
- to suggest a guideline for community discussion
SEN-ED
Basic information:
Following DataCite
Discipline-specific information:
For reuse of the dataset
Hsu et al., accepted
13. SEN Wiki - to make data and methods discoverable
SEN-KB
14. SEN Sediment and Instrument Lists
- for knowledge transfer
Where have others bought sediment and instruments?

22. SEN + Geosemantic Framework =
better documented datasets and connections to models
23. What defines success for SEN?
• SEN information is easily discoverable and accessible:
Earth surface process community knows where to go to find
information and resources on sediment experiments
• SEN and CI know each others’ capabilities and needs:
Domain scientist knowledge of cyberinfrastructure resources much
higher than without EarthCube involvement, CI has a use case
• SEN begins a culture change of sharing and documenting data:
New experimentalists expect to share information about their
experiments
24. Challenges to reaching SEN’s goals
• Reaching our audience and achieving critical mass for sharing
• Long-term storage of large volume datasets
• Coming to consensus, agreeing on shared formats
• Making time for SEN in the research workflow
• Sustainability of SEN activities
