CoESRA virtual experiment environment

 

About

Sound science, and the decisions we make based on it, relies on reproducibility. The ability for another researcher to replicate analyses to validate theories and produce complimentary or entirely new science is essential - something that the great thinkers like Aristotle became well aware of when coming up with ‘scientific method’. Reproducible science increases a project’s transparency and is essential in facilitating auditing and independent review.

Reproducibility not only relies on the reuse of data, something which is at the heart of TERN, but also the ‘reuse of analyses’. A new joint project between fellow NCRIS capabilities, TERN and the Australian National Data Service (ANDS), aims to not only promote reusable data, but also reusable analysis processes.

The project will provide an outlet for people to compose, execute and share their experiments.  Specifically, it aims to connect existing TERN infrastructure and other data services running from the National eResearch Collaboration Tools and Resources (NeCTAR) and stored in Research Data Storage Infrastructure (RDSI) with the tools for analysis and manipulation to develop a CoESRA (collaborative environment for ecosystem science research and analysis) virtual experiment environment.

The CoESRA is a workflow-based web-platform that allows researchers to perform complex analyses without having to set up the experiment from scratch and worry about having enough resources to run the analysis. The tool will provide an opportunity not only to re-use data but also tools for data manipulations, scripts for data visualisation and algorithms for analysis processes. Once a specific analysis is conducted, the entire process chain can be stored and shared with other scientists improving the reproducibility and repeatability of the experiments. Finally, the workflow can published to Research Data Australia (RDA).

And, it's not just researcher that will benefit from the project. The community will gain access to data streams, tools and often hidden ‘pipeline’ processes to leverage further knowledge about ecosystem science experiments.

To showcase the usability of CoESRA, the project will use two real-life case studies: 1) ‘animal conservation and management plan’; and 2) ‘ecosystem assessment of Mountain Ash forest’.

The first case study will link conservation planning software Marxan and animal tracking information to increase the analytical power of these ecological tools and create a repeatable and reusable workflow for subsequent studies of habitat conservation.

The second case study will bring together data and analysis required to apply IUCN Red List of Ecosystems criteria to the Mountain Ash forest ecosystem and make a repeatable (e.g. re-run in the future with updated time windows and updated ecological parameters) workflow for the ecosystem assessment of Mountain Ash forests in the central highlands of Victoria. The workflow will also enable researchers to re-run the entire assessment with additional data for certain criteria.

Not only will this exciting project reduce the overheads of setting up environmental analyses but will also provide a great benefit to the science community via the creation of a platform for re-usable, repeatable and above all reproducible scientific analyses.

The CoESRA is accessible from https://www.coesra.org.au and FAQs on how to access and use CoESRA virtual desktop are available in https://www.coesra.org.au/#/faq.
