  1. NSF Expeditions in Computing Understanding Climate Change: A Data Driven Approach Illustrative Research Activity: Automatic Global Ocean Eddy Discovery Ocean eddies are a critical component of our planet as they: • Have mitigating climate change effect (Nature 2011) • Impact marine ecosystems (Science 2011) • Impact the intensity of hurricanes (Mon. Wea. Rev. 2013) • Impact local cloud cover and rainfall (Nat. Geo. 2013) Real-time eddy detection could help search for missing plane Eddies are dynamic unlabeled spatio-temporal patterns • Noisy • High variability • Uncertain Data challenges Methods challenges • Large unlabeled data • Partially observable objects • Evolutionary process • Dynamic features • Identify discrete objects in a continuous field Faghmous et al. AAAI (2014) Faghmous et al. ICDM (2013) Faghmous et al. AAAI (2013) Faghmous et al. CIDU (2012) Best Paper Award Faghmous et al. AAAI (2012)

  2. Socially relevant applications • Associate eddy activity with: • Changes in hurricane tracks • Changes in phytoplankton concentrations • Changes in near surface salinity and temperature • Impact on coral reefs • Transformative Results • Physics-guided data mining • Climate Informatics • Evaluation of unsupervised learning methods with no “ground truth” • Produced world’s most comprehensive eddies dataset spanning 20+ years • First public dataset produced by computer science for broader climate science community
