What do slag, marine fossils and tin crystals have in common? They are buried at different depths in Hudson River mud and their microscopic images are both beautiful and informative. They can tell us about past historical events-how travel on the Hudson evolved from sloops to steamboats to diesel, when large hurricanes drove seawater into the Hudson, and possibly when molten tin from an exploding comet fragment coated debris dropping into the Hudson. Come see and hear about the environmental history of the Hudson as told by images of marvelous mud.
Dallas Abbott is an Adjunct Research Scientist whose research has ranged from impact craters to historic climate disasters. Dallas holds a special place in Earth2Class: She has provided workshops every year since 2002! In this year’s talk, Dallas will share results from some of the recent research she has undertaken to learn more about Earth’s geologic history.
DEE BREGER of MICROGRAPHIC ARTS is a “microphotographer”–her specialty is making images of extremely tiny objects using scanning electron microscopes. Dallas and Dee have worked together for many years, a collaboration that continues today with images in Dallas’s SLIDESHOW FOR TODAY’S WORKSHOP: Abbott_Earth_to_Class_2014a
