Replacement Fund . 3 When the department expanded after the formation of the SUNY system, there was one faculty member in each major area (mineralogy, petrology, Meet the NEW Faculty .. 4 structure etc.). The advantages of this model include excellent undergraduate education and a broad range of research interests. The disadvantage of this Duttweiler Geological approach is that each faculty member worked essentially alone, which is a Field Station . 7 significant disadvantage in competing for sponsored research funds. When Mike Sheridan was selected to replace Chet Langway as Chair in 1990, he began a reorganization of the department into concentrated Research News research programs. This resulted in the formation of two major programs: Paoha Island environmental geology and volcanology. While not all of our research falls How did it emerge? . 8 neatly into these two programs, every one of the five new faculty we have recently hired strengthens these research areas. As a result we have SW Pacific Ocean, collaborative research in several areas, and our research groups including the East of New Zealand . 11 rock fracture group (Becker, Fountain, Jacobi, Peacock and Baker) and the volcanology group (Bursik, Gregg, Sheridan and Parfitt) are large and diverse.

  • Pathways and Mechanisms of Late Ordovician (Katian) Faunal Migrations of Laurentia and Baltica
    Estonian Journal of Earth Sciences, 2015, 64, 1, 62–67 doi: 10.3176/earth.2015.11 Pathways and mechanisms of Late Ordovician (Katian) faunal migrations of Laurentia and Baltica Adriane R.

Late Ordovician strata within the Cincinnati Basin record a mass faunal migration event during the C4 and C5 depositional sequences. The geographic source region for the invaders and the paleoceanographic conditions that facilitated dispersal into the Cincinnati Basin has previously been poorly understood. Using Parsimony Analysis of Endemicity, biogeographic relationships among Laurentian and Baltic basins were analyzed for each of the C1–C5 depositional sequences to identify dispersal paths. The results support multiple dispersal pathways, including three separate dispersal events between Baltica and Laurentia. Within Laurentia, results support dispersal pathways between areas north of the Transcontinental Arch into the western Midcontinent, between the Upper Mississippi Valley into the Cincinnati Basin, and between the peri-cratonic Scoto-Appalachian Basin and the Cincinnati Basin. These results support the hypothesis that invasive taxa entered the Cincinnati Basin via multiple dispersal pathways and that the equatorial Iapetus current facilitated dispersal of organisms from Baltica to Laurentia. Within Laurentia, surface currents and large storms moving from northeast to southwest likely influenced the dispersal of organisms. Larval states were characterized for the Richmondian invaders, and most invaders were found to have had planktotrophic planktic larvae.

I looked up its northwestern flank and wanted to stand on top of its white cone. It beckoned, cool and refreshing, framed by an azure sky, miles from where I stood. Around me, heat waves rose from the pavement and dust devils swirled among the cornstalk pyramids by the village gate. I realized I must not underestimate this alpine goliath. Pico de Orizaba (18,491 feet) is the third highest mountain in North America, after Denali in Alaska and Mount Logan in the Canadian Yukon. Located in Mexico’s volcanic belt, on the border of the states of Veracruz and Puebla, Orizaba rises prominently from a pancake-flat patchwork of corn and cactus in central Mexico.

Every single one of these layers tells its own story about what North America was like when that layer was deposited.

That is crazy! …to find out, “How did our amazing continent get to be the way it is?” EMILY WOLIN (Geophysicist): Underneath Lake Superior, that’s about 30 miles of volcanic rock. KIRK JOHNSON: Thirty miles of volcanic rock? How did the landscape shape the creatures that lived and died here? Fourteen-foot-long fish, in Kansas.

Hageman2 1Department of the Geophysical Sciences, University of Chicago, 5734 South Ellis Avenue, Chicago, IL 60637 〈[email protected]〉 2Department of Geology, Appalachian State University, Boone, North Carolina 28608, USA 〈[email protected]〉 Abstract.—The Ediacaran to lower Cambrian Chilhowee Group of the southern and central Appalachians records the rift-to-drift transition of the newly formed Iapetan margin of Laurentia. Body fossils are rare within the Chilhowee Group, and correlations are based almost exclusively on lithological similarities. A critical review of previous work highlights the relatively weak biostratigraphic and radiometric age constraints on the various units within the succession. Herein, we document a newly discovered fossil-bearing locality within the Murray Shale (upper Chilhowee Group) on Chilhowee Mountain, eastern Tennessee, and formally describe a nevadioid trilobite, Buenellus chilhoweensis n. sp., from that site. This trilobite indicates that the Murray Shale is of Montezuman age (provisional Cambrian Stage 3), which is older than the Dyeran (provisional late Stage 3 to early Stage 4) age suggested by the historical (mis)identification of “Olenellus sp.” from within the unit as reported by workers more than a century ago.

  • Lichen-Associated Bacterial Diversity in the Trans-Mexican Volcanic Belt
    Lichen-associated bacterial diversity in the Trans-Mexican Volcanic Belt A final report for the Explorers Club Exploration Fund, Diversa Award, 2007 Submitted April 2008 Brendan P. Hodkinson PhD Candidate, Biology Department Duke University, Durham, NC 27708 443-340-0917; [email protected] Google Earth™ view of the eastern portion of the Trans-Mexican Volcanic Belt, facing east from ~20 miles above the Valley of Mexico. Major landmarks include three volcanoes (Iztaccíhuatl, Popocatépetl, and Pico de Orizaba), a crater lake (Laguna Alchichica), and two major cities (Puebla and Xalapa). 2 In August 2007, I traveled to the biologically diverse eastern portion of the Trans- Mexican Volcanic Belt to collect fresh lichen specimens for my studies of bacterial diversity. My journey began in the city of Puebla, where I spent my first night. Nearby was the Parque Nacional Izta-Popo, home to North America’s second and third highest volcanoes, Popocatépetl (5,452 m) and Iztaccíhuatl (5,230 m). Iztaccíhuatl is the smaller of the two volcanoes, and, unlike Popocatépetl, is no longer active. Also, the peak of Iztaccíhuatl is the lowest point in Mexico with permanent snow and glaciers. This is a perfect place for sampling lichens because, in a relatively short amount of time, diverse lichen samples can be collected from a variety of elevations (at least 3,000 m of elevation change within the park). First morning in Mexico. Volcán Popocatépetl seen from the city of Puebla, with a hint of Volcán Iztaccíhuatl behind my head. 3 I then traveled to the state of Veracruz, an area that is world renown for its amazing biodiversity.
