Transient & Data-intensive Astronomy
3
New era: seeing events as they occur (Almost) here now
ALMA, EVLA in radio Ice Cube neutrinos
On horizon 24-42m optical? LIGO south? LSST = SDSS (40TB)
every night! SKA = exabytes
Simulations integrate all physics
Astronomy 1500-2000 was passive. No longer!
?
Will require integration across disciplines, end-to-
end
Communities need to share data, software,
knowledge, in real time

Scenarios like this in all fields “Heroic Age of Digital Observation”

Framing the Challenge: Science and Society Transformed by Data
Modern science Data- and compute-
intensive Integrative, multiscale 4 centuries of constancy,
4 decades 109-12 change! Multi-disciplinary
Collaborations Individuals, groups,
teams, communities
Sea of Data Heroic Age of Digital
Observation 5
We still think like
this…
…But such radical change cannot be
adequately addressed with (our current) incremental
approach!
Students take note!

The Shift Towards a “Sea of Data” Implications
Science & society are now data-dominated Experiment, computation, theory Fourth paradigm US mobile phone traffic exceeded 1 exabyte!
Classes of data Collections, observations, experiments, simulations Software Publications
Totally new methodologies Algorithms, mathematics, culture
Data become the medium for Multidisciplinarity, communication, publication…science
6
Fundamental questions become focused around data: How to remove boundaries? How to incentivize sharing?
How do we attribute credit for this new publication form? How are data peer reviewed? What is a publication in the modern data-rich world?

Changes Coming at NSF for Data! Long-standing NSF Policy on Data
“Investigators are expected to share with other researchers, at no more than incremental cost and within a reasonable time, the primary data... created or gathered in the course of work under NSF grants”
NSF now requires a Data Management Plan (DMP) DMP will be ≤2-page supplement to the proposal DMP subject to peer review; criterion for award It will not be possible to submit proposals without DMP Customization by discipline, program necessary
Developing unifying data framework for science Should connect globally; discussions underway with EU
National Science Board beginning to examine policy for access and openness of data and publication
7
Sharing data, software will be needed for both interdisciplinary work and reproducibility

Recommendation of NSF Advisory Committee on Cyberinfrastructure
ACCI "The National Science Foundation should create a program in
Computational and Data-Enabled Science and Engineering (CDS&E), based in and coordinated by the NSF Office of Cyberinfrastructure. The new program should be collaborative with relevant disciplinary programs in other NSF directorates and offices."

Critical Lessons to Take Home Science and society profoundly changing Comprehensive approach needed to address
complex problems of 21st century All elements must be addressed, not just a few;
can’t even start to address problems without all Many exponentials: data, compute, collaborate
Data-intensive science increasingly dominant Modern data-driven CI presents numerous crises,
opportunities
Academia and Agencies must address Rethinking Academic Structures, Curriculum, P&T NSF Responding through CIF21, changes in
implementation of data policy, new programs 9
