Collaborative Environment for Ecosystem System Science Analysis and Synthesis (CoESRA)

Presentation by Siddeswara Guru

Outline• Motivation

• Reproducible science

• Challenges• CoESRA• Use Case: IUCN Red List of Ecosystems

Assessment.• Summary

Motivation

Reproducible Science

Duplicate the scientific experiments or reproduce experiment results.

Source: nature.com

Challenges• Lack of culture to make scientific claims

reproducible• Lack of detailed information about data

and code even after they are published• “lack of an integrated infrastructure for

distributing reproducible research to others”1

• Despite the journal Biostatistics’ policy since 2009, as of 2011 only 4% of articles had “R” kite-mark.

• In US, $28 billion per year spent on clinical research that are not reproducible2.

Integrated Infrastructure

• Cloud-based platform• Scientific workflows executable

on a easily accessible platform

"one of the most effective ways to promote high-quality science is to create free open-source tools that give scientists easier and cheaper ways to incorporate transparency into their daily workflow:"3

Scientific workflow• Series of structured

interconnected computational activities

• Visual front-end to build experiments using components.

• Components can be implemented in high-level and/or scripting languages.

Kepler Scientific workflowFeatures

• Ability to create components in different programming languages

• Reusable components: actors and Directors

• Easy to run workflows as distributed tasks

• Platform independent re-usable experiments

• Possibility of repeatability and reproducibility

We want to develop an infrastructure where computational experiment e that has been developed at time t on a hardware and software infrastructure h using data d is reproducible at time t1 on same hardware and software infrastructure h using the same data d.

IUCN Red List Ecosystem Assessment of Mountain Ash Forest

Mountain Ash Forest Ecosystem Risk Assessment

• Unique biodiversity, • World tallest flowering plants (over 100 m),• Contribute to water and timber production,• subject to wildfire. • Apply IUCN Red List of Ecosystem criteria for risk assessment2
