Drought coincident with aeolian activity in a Great Lakes coastal dune setting during the Algoma Phase (3.1–2.4 ka), southwest Michigan

Publikováno v: Journal of Great Lakes Research. 47:1468-1484

Aeolian studies of Lake Michigan’s coastal dunes have yet to elucidate what factors control their episodic activity over the past 5000 years. High lake levels exposing sand along with increased storminess is generally accepted for high perched dune

Effects of wind patterns and changing wind velocities on aeolian drift potential along the Lake Michigan shore

Autor: Brian P. Yurk, Edward C. Hansen

Publikováno v: Journal of Great Lakes Research. 47:1504-1517

Climate influences the amount of wind energy available to transport sand in coastal dune complexes. Wind data from meteorological stations were used to calculate aeolian sand drift potential along the Lake Michigan shore and surrounding region. Data

Waxing and waning slacks: The changing ecohydrology of interdunal wetlands/slacks in a Lake Michigan coastal dune complex during rising Lake Michigan-Huron levels

Autor: Suzanne DeVries-zimmerman, Brian P. Yurk, Alexandra Donaldson, Edward C. Hansen, Kathleen M. Fast

Publikováno v: Journal of Great Lakes Research. 47:1565-1580

Since 2016 we have studied the largest interdunal wetlands/slack lying within a deflated parabolic dune east of Lake Michigan. Geologic cross-sections show ∼ 15 m of sand and gravel beneath the dunes, creating an aquifer hydraulically connecting La

Zircon as a Recorder of Trace Element Changes during High-Grade Metamorphism of Neoarchean Lower Crust, Shevaroy Block, Eastern Dharwar Craton, India

Autor: Daniel E Harlov, Daniel J Dunkley, Edward C Hansen, C Ishwar-Kumar, Vinod Samuel, Tomokazu Hokada

Publikováno v: Journal of Petrology

Systematic changes in whole-rock chemistry, mineralogy, mineral textures, and mineral chemistry are seen along a ca. 95-km traverse of late Archean granitoid orthogneisses in the Shevaroy Block, Eastern Dharwar Craton, southern India. The traverse pa

Experimental observations of detached bow shock formation in the interaction of a laser-produced plasma with a magnetized obstacle

Autor: Joseph M. Levesque, Andy S. Liao, Patrick Hartigan, Rachel P. Young, Matthew Trantham, Sallee Klein, William Gray, Mario Manuel, Gennady Fiksel, Joseph Katz, Chikang Li, Andrew Birkel, Petros Tzeferacos, Edward C. Hansen, Benjamin Khiar, John M. Foster, Carolyn C. Kuranz

The magnetic field produced by planets with active dynamos, like the Earth, can exert sufficient pressure to oppose supersonic stellar wind plasmas, leading to the formation of a standing bow shock upstream of the magnetopause, or pressure-balance su

Dunes of the Laurentian Great Lakes

Autor: Brian P. Yurk, Zoran Kilibarda, Todd A. Thompson, Brian E. Bodenbender, Suzanne DeVries-zimmerman, Edward C. Hansen, Deanna van Dijk, Robin G.D. Davidson-Arnott

Publikováno v: Dunes of the World ISBN: 9783030404970

Most dunes along the 16, 000-km long shorelines of the Laurentian Great Lakes formed after lake levels fell from highs at 5 to 3.5 ka. Foredunes develop during decadal scale variations in lake levels, forming during low and eroding during high lake l
