Current research programs (June, 2021):
Completed main 2020 project: BOOK: Geologic TimeScale 2020 (Gradstein, Ogg, Ogg and Schmitz; published Nov 2020 by Elsevier – see Publications below); which follows four previous compilations -- Geologic Time Scale 2004 (Gradstein, Ogg and Smith; Cambridge Univ. Presss); Concise Geologic Time Scale 2008 (Ogg, Ogg and Gradstein; Cambridge Uni. Press); and Geologic TimeScale 2012 (Gradstein, Ogg, Schmitz and Ogg (coordinators), Elsevier Publ.), and A Concise Geologic Time Scale 2016 (Ogg, Ogg and Gradstein; Elsevier Publ.)
Concise Geologic Time Scale 2024; and TimeScale Creator cloud-based databases
This will be a publication by James Ogg and Gabi Ogg as contracted by Cambridge Univ. Press (ca. 250 pages, 13 chapters; for submission in mid-2023 with accompanying databases). It will be in coordination with subcommissions of the International Commission on Stratigraphy and other period-level geochronology experts. It is intended that the supporting databases will be part of the DDE system.
East Asia paleogeography: invited co-coodinator (China-USA-Australia team) of 5-year synthesis program hosted by Chengdu University of Technology.

TimeScale Creator database and visualization system (joint product of Purdue engineering and geoscience student teams, Geologic TimeScale Foundation, and International Commission on Stratigraphy)
Global databases of basin stratigraphy (joint projects with different geological surveys and stratigraphy commissions, including China, Australia, Germany, Canada, India, Argentina, etc.), and of Paleogeography of China (in conjunction with China institutions and Chris Scotese)
Astronomical tuning of the Mesozoic Era
High-resolution correlation of Boreal and Tethyan faunal and land-marine realms during Triassic and Jurassic using integrated magnetostratigraphy, sequence stratigraphy, and cycle-stratigraphy
Super-greenhouse conditions and elevated ocean acidity resulting from “super-plume” large igneous provinces (e.g., the Ontong-Java Plateau of mid-Cretaceous; Wrangellia LIP of mid-Triassic; Siberian Traps of end-Permian)
