STEP community experiment December 2012

On December 11, 2012, as part of the EarthCube Experimental Stratigraphy Workshop, a community experiment was run in the STEP Basin at University of Texas. Austin. In the experiment, a delta was built into standing water as coarse sediment, fine sediment, and water were fed into the basin. The experiment ran for 8 hours, and the sediment flux, water flux, and basin subsidence were varied as pre-specified by workshop participants. After the experiment, the basin was drained and vertical slices were taken and photographed in order to see the internal stratigraphy of the delta (movie #2 below).

In the spirit of a community experiment, data from the experiments, including control programs, deposit slice images, and topographic scans, are available for analysis in the shared workshop materials folder. Direct links to the raw data are summarized at the bottom of this post. We have also set up a Community Experiment Forum to capture ideas on how to analyze these shared data. You can contribute ideas and vote on other's suggestions. See what others are saying and add your idea!

Share your data with figshare

One goal of the Sediment Experimentalists group is to keep readers informed of new tools that may help with data management and archiving. One such tool is figshare, which "allows researchers to publish all of their research outputs in seconds in an easily citable, sharable and discoverable manner."

"figshare was started by a frustrated Imperial College PhD student as a way to disseminate all research outputs and not just static images through traditional academic publishing."

Do you share figshare founder Mark Hahnel's frustration? If so, you are encouraged to try out the site and then let the Sediment Experimentalists know about your experience (by email or blog comment). You can share and organize figures, datasets, media, papers, posters, and presentations.

Join our EarthCube group - Be informed!

Are you still confused about the entity called EarthCube? The best way to find out more is to join the EarthCube site. EarthCube has recently formed groups for all of the identified End-User communities. Since we held an EarthCube workshop in December 2012, we have a group called Experimental Stratigraphy. (Although it is named after our inaugural workshop, we plan to make the discussion more broad to encompass all Sediment Experiments.)

You are urged to sign on, join, and recruit others so that we can "provide a forum in which you can continue discussions from your workshop, post important documents (or links to your Google docs folder) and keep up the momentum generated during your workshop."

You can also check out the latest on the other groups that are active in EarthCube. This is yet another way to keep up with the multitude of opportunities available in all things data and cyberinfrastructure. It also helps to place our community on the map and draw attention to our data and cyberinfrastructure dreams.

If you haven't already, it is time to join the not-so-new experiment of Social Media:

Surface Process Experiments -- Town Hall Report

It has been about one year since we started this group, and we want to thank everyone who has contributed their time, suggestions, or even just interest and attention. In the next few emails we will report on some of the recent events. The first report is on the Town Hall that was held at the AGU Fall Meeting. If this summary sparks any ideas or comments you’d like to share, contact us!

Town Hall summary

On December 7, 2012, we convened a town hall meeting on “Surface Process Experiments – A Community Discussion” to solicit from the AGU Earth and Planetary Surface Process (EPSP) focus group community opinions, challenges, and future directions on managing Earth-surface experimental data sets. The meeting included six panelists with perspectives from collaborative community initiatives, funding agencies, and journal publishers. Approximately 70 people attended the meeting, which was funded by NCED (A full report and transcript of the meeting is available at: http://tinyurl.com/sedex-townhall2012).

Panelists and audience members expressed universal concern for the current lack of infrastructure and support for data management and sharing for our particular data types. Participants expressed challenges falling into three primary categories:

(1) Data structure and description
: Metadata describing data provenance, structure, and uncertainty are as important if not more important than raw data itself. Templates and guidelines would help, though the diversity of experimental types and institutional directives likely preclude a universal standard.

(2) Long-term archiving: Preserving data in usable and accessible formats over time spans far exceeding typical funding and project cycles (>10 years) is a challenging and expensive prospect but extremely important for our community.

(3) Publication and recognition
: Scientists will only invest their time in data management if they feel their efforts are recognized, and publication of citable “data papers” appears a natural answer to this question. AGU journals support publication of data papers, but fundamental questions about data paper structure, scope, and attribution must be overcome to attract more than a token number of such submissions.

Participants identified limited human, computing, and financial resources as major barriers to proper data management, especially in smaller universities and facilities. Furthermore, data and experiments come in many different forms (and degrees of processing), and it is hard to imagine a generalized way to describe these. Rather than starting from scratch, many participants suggested that we learn from and build on existing resources, such as the NCED data repository and the Consortium of Universities for the Advancement of Hydrologic Science, Inc. (CUAHSI) Hydrologic Information System (HIS). The best approach to managing data will likely combine top-down directives and support (for example, NSF could potentially provide support for long term data archiving and centralized databases) with bottom-up engagement by Earth-surface scientists to define database structures, templates, and guidelines.

Summer Update for the Sediment Experimentalists

Dear all,

Hope you are all having a great summer. To continue our Sediment Experimentalist community-building, here are two ways you can get to know more experimentalists. 

(1) Contribute to our AGU Session: EP002 Advances in Experimental Earth Surface Processes
(2) Put your laboratory on the Map!


(1) Contribute to our AGU Session: EP002 Advances in Experimental Earth Surface Processes

If you are attending the AGU Fall meeting, please participate in our session by submitting an abstract! We hope to be able to meet many of you there. 

In addition to highlighting exciting new physical experiments and methods, we will use this session will spur community conversations about collecting, sharing, and archiving experimental data and tools, and building collaborations between experimentalists, modelers, and theoreticians. 

Invited Speakers:
Leonard Sklar (San Francisco State University)
Stephen DeLong (Biosphere 2)
Jorge Abad (University of Pittsburgh)
Alessandro Cantelli (Shell Oil)

Description:
Physical experiments designed to clarify mechanisms and rates of Earth's surface evolution have contributed much to our understanding of Earth science. By highlighting recent progress, including new methods and techniques, we seek to create a venue to coalesce the community around current opportunities to share and develop resources for experimental science. Presentations and posters are sought from the wide range of surface process experiments where material transport plays a central role, especially those that integrate new and old datasets, use novel techniques for observations and data collection, develop reusable tools to analyze or share large datasets, or require cross-disciplinary communication.

(2) Put your laboratory on the Map!


Our Google Fusion Table is growing, but we want to see where other laboratory experiments are in progress. In particular, how about adding some non-U.S. facilities?



(Click map above for Google Map view)

The Fusion table was put together not only to list completed datasets, but also to serve as a resource for discovering other experiments and experimentalists. We encourage you to add an entry that briefly describes your lab or work in progress. You can read the Instructions for contributing or simply email sedimentexp@gmail.com or any one of us to help.

Another resource that you may want to know about and contribute to is Open Sediment Science, which maintains a list of Experimental Facilities for Geomorphology!
