Reproducible research for an irreproducible planet
“The point is, you can never be too greedy.”
(says the most powerful person on the planet)
Why open up and share?
…If your interest lies in being the most powerful person rather than the planet
True!
23 core global risksGeo-datasets/-processes:
Multi-scale data and processes Interdependent Uncertainties
Communication across disciplines Informed decision making
Lack of sufficient dataLack of consistent theory
Deep uncertainties
The Black Swan
How do we decipher and maintain the pulse of the precious?
There is only One Earth (on Earth)
How to constrain it?
The task is …“simple”: … too much, too messy … too expensive … ill-posed, non-unique … poorly constrained, unverifiable
1) collect data 2) simulate 3) make model 4) interpret
Data sets are: complex, noisy, diverse unique (unrepeatable)
interconnected difficult to understand
The problem
Scientists
We need to:Value rare/unique datasets, evaluate outputs
Consider & communicate uncertainties Communicate across disciplines
Get facts and reason back!
Seismic datasets
Promote exchange of seismic and other geophysical data and knowledge through the use of standards for network operations and data formats, and
through pursuing policies of free and unrestricted data access. www.iris.edu (since 1990s)
EPOS will bring together Earth scientists, national research infrastructures, ICT (Information & Communication Technology) experts, decision makers, and public to develop new concepts and tools for accurate, durable, and sustainable answers to societal questions concerning geo-hazards and those geodynamic phenomena (including geo-resources) relevant to the
environment and human welfare.

There’s another Elephant in the room….
Schaeffer and Lebedev 2013
“The variety of beings should not rashly be diminished.”(Kant’s anti-razor, 1781)
… my model is much better than yours!
Communication lessons…
My statement: “a lot of our current work in seismology focuses on
improving estimates of seismic hazard by using sophisticated numerical models ”
How to communicate (deep) uncertainties?
…BBC turns this into:“"Tarje Nissen-Meyer says lots is being done to improve the science of predicting, with sophisticated numerical
models.”

1.Facilitating information transfer (for science, society, policy) 2.Reproducibility of methods, data processing, publications 3.Inclusivity: access of (publicly funded) publications for any reader 4.Managing & mining large datasets 5.Connecting disciplines 6.Equality (across hierarchies, genders, ethnicities, social groups) 7.Multidisciplinary modern science, not monolithic ivory vanity 8.Engage the public, policy-makers, pupils
Why open up and share?What’s missing?1.Recognition for data collection & software development (doi) 2.Avoid exploitation, maintain quality control 3.Allow for weighted referencing 4.Metrics for recognising transferable & transformative research:
Across disciplines, collaborative, open
