  • 3. PALEOMAP Project 2013 Highlights • New Global Plate Model (Scotesev13a) – Fixes “gaps”; High resolution ocean age polygons • Finalized PaleoAtlas Time Slices: – One plate tectonic reconstruction for every stratigraphic stage (103 intervals) – Additional paleogeographic maps for every Supersequence Boundary (SSB) & Maximum Flooding Surface (MFS) (~140 total paleomaps) – “PaleoAtlas Toolbar” for PaleoGIS (Rothwell Group) • Began work on Earth System Archive – Define +50 ESA variables – 4 new paleoclimate models (early Miocene, late Albian,Pennsylvanian, &mid Silurian) • Finalized Global Geology.com – batch import & export tools • • Publication of Boucot, Xu & Scotese (2013) by SEPM Relocated back to Chicago (Evanston) – To work on book “History of the Earth”; words to go with maps (documentation & storytelling)
  • 4. PALEOMAP Plans for 2014 • • • Update & Populate Time Slices Focus on Earth System Archive – 4 additional paleoclimate simulations (total ~30) – Build core of ESA with ‘GANDOLPH’ paleoclimate results – Build user-friendly “backtracking “ tools New Layers for PaleoAtlas – – – – – – • • • “Paleogeology” from Khain et al. atlases (~40 maps) Lithofacies symbols & shading Paleomagnetic poles & vectors Hot Spots & LIPS Geologic info from: Global Geology & PaleoBiology DB, COSUNA Gridded raster versions of info from Earth System Archive Resurrect Regional Plate Models – SE Asia, Caribbean & GOM, W.Indian Ocean, Circum-Arctic, South Atlantic, & Neoproterozoic (back to 1300 Ma) Provide paleogeographic 1x1 grids for Rothwell’s Paleoclimate Software Rough drafts of 20-25 Chapters of “History of the Earth” (~18 done)

Earth System Archive Variables • Type I Descriptions/Measurements (17) e.g. basin name/ PaleoDEM • Type II Global Geology (22) e.g. Lithology, Formation Name • Type III Paleoclimate (FOAM) (18) e.g. Mean Annual Temperature) • Type IV Derivative (Composite) (infinite) e.g. Carbonate Facies Probability
  • 29. Earth System Archive: Deliverables Digital Data 2 Geologic “Data Cubes” of ESA variables e.g. Mean Annual Temperature (MAT), Carbonate Facies Probability (CFP), Carbonate/Clastic Ratio (CCR) Cube (1) in paleoLat & paleoLong” to overlay paleomaps Cube (2) in modern Lat & Long for comparison with unreconstructed data & maps Software “BackTracker” Program that creates bivariate plots of ESA variables back through time.
