Description:

Paleoclimate observations are crucial to assessing current climate change in the context of climate variations across the decades and centuries. However, these observations usually come in non-standard formats, forcing scientists to spend a significant fraction of their time searching and accessing the data they need in the form they need it. This makes science progress slow, deters scientists from doing global studies where data is more heterogeneous, and hinders data re-use. In the 21st century, we should be able to do much better

The LinkedEarth project is manifesting a better future for paleoclimate research by creating an online platform that (1) enables the curation of metadata for publicly-accessible datasets by experts themselves, and (2) fosters the development of community ontologies and standards for paleoclimate metadata. In the first part of this talk, I will describe the metadata standardization efforts undertaken under the LinkedEarth umbrella and the many practical lessons learned about what works and does not work in terms of widespread adoption of semantic technologies. In the second part of this talk, I will demonstrate how this metadata standardization effort can help with the day-to-day work of paleoclimatologists by broadening access to cutting-edge data-analytic tools that can be applied to a wider array of datasets than ever possible before.

Bio: Dr. Deborah Khider is a postdoctoral researcher affiliated with the USC Earth Sciences department, collaborating with ISI researchers on projects concerning the use of AI in climate research. Deborah graduated in 2011 with a PhD in Ocean Sciences from USC, focused on the paleoceanography of the Indonesian Seas. Her postdoctoral work at the University of Texas at Austin and the University of California at Santa Barbara has shifted her interest towards synthesis of paleoclimate records and uncertainty quantification using Bayesian and Monte-Carlo-type methods. She is currently involved in several projects for representing and capturing metadata for geoscience data and models.
