May 9, 2017 - May 13, 2017

LinkedEarth will make a show of force at the next PAGES Open Science Meeting, with 1 session and 3 presentations:

Julien will give the Plenary Lecture on Wednesday May 10th (10:00-10:30am), Mozart Room.

The future of old things: geoinformatics for better paleoscience 

Abstract: By some accounts, paleoscientists spend up to 80% of their time trying to access the data they need, in the form they need it. In the 21st century, we should be able to do much better. This lecture will review recent progress made by the LinkedEarth project, which relies on data standards and artificial intelligence to enable scientists to spend more time doing the science they want to do. LinkedEarth is manifesting a better future for paleoscience by creating an online platform that (1) enables the curation of a publicly-accessible database by paleoclimate experts themselves, and (2) fosters the development of community standards. In turn, these developments enable cutting-edge data-analytic tools to be built and applied to a wider array of datasets than ever possible before, supporting more rigorous assessments of the magnitude and rates of pre-industrial climate change. We will start by illustrating these principles in the context of the PAGES 2k project, and outline how they may serve the PAGES community as a whole. In particular, we will illustrate how to go from spreadsheets to syntheses (PAGES 2k). We will dwell on community participation in the first paleoclimate data standard. We will present GeoChronR and Pyleoclim, new open-source tools compatible with these standards and enabling cutting-edge paleoscience. We will finish by some remarks on interoperability, enabling cross-talk between scientists within a field, across fields, and between data and models. In our vision of the future, machines serve scientists, not the other way around. Yet, the process needs a lot of human input, and the participation of the PAGES community will be recognized and further encouraged.

He will also give a lecture on Patterns of climate change over the Common Era,  in the session  “Regional and transregional climate variability over the past 2000 years”, Thursday May 11th, Mozart Room.

Finally, Julien will co-chair (with MARUM’s Michal Kucera)  session 26 (Data Stewardhip for Paleosciences), whose oral session will take place Saturday May 13th, Room11 Auditorium, 11:00-13:00 and include an open discussion.  Nick will be presenting  Linked PaleoData: What is it and what can it do for you? (11:15-11:30) 

Abstract:

Over the past several decades the paleoclimate community has developed a diverse and valuable set of paleoclimatic observations. These data have the geographic extent and temporal density to enable scientific inquiry into long-term and preindustrial climate dynamics; a primary aspiration of cutting edge and societally relevant research in the field. However, we still lack efficient access to these data and the critical metadata that bolster intelligent use of nuanced observations. This bottleneck slows scientific discovery and prevents the field from fully entering a data-driven paradigm of discovery that has enabled great leaps in other scientific fields. In recognition of this, paleoclimatology is beginning a data revolution. At the heart of this revolution is the need for a structured data format that can interact with our scientific tools, and that is sufficiently flexible to span the breadth of paleoclimatology.

Here we present Linked PaleoData, or LiPD, a data container flexible enough to adapt to the broad and evolving needs of the paleogeosciences, but structured enough to facilitate efficient and intelligent reuse of data and metadata. The LiPD framework accommodates measured and inferred paleoenvironmental and geochronological data, as well as any set of metadata, at any level of the dataset, from the entire collection down to individual observations. LiPD also leverages recent advances in knowledge representation, primarily through its connection to Linked Earth. LiPD has proven to be powerful in large data synthesis efforts, such as the PAGES2k Phase 2 temperature and the iso2k efforts. It is also broadly useful at the site-level, as its capacity to store expanded methodological metadata and geochronological ensembles make it the preferred data format for emerging platforms for uncertainty quantification, including CSciBox and GeoChronR. Finally, low-level interaction with the LiPD format is provided by utilities available in Matlab, Python and R.

 In the ensuing session, Julien will give a brief tour of the LinkedEarth wiki to kick off the discussion.
