Calcareous Nannofossils and Paleogene Hyperthermal Events of the Salisbury Embayment

Jean Self-Trail

U.S. Geological Survey Reston, VA

Multiple extreme and rapid warming events, also called hyperthermals, occurred during the Late Paleocene and Early Eocene. Calcareous nannofossils (a type of marine algae), along with other microfossils, carbon isotopes, and lithology are used to document changes in ocean acidification and sedimentation during three of these events in the Salisbury Embayment. I will discuss ongoing research on the Pre-Onset Excursion (POE), the Paleocene Eocene Thermal Maximum (PETM) and present a “sneak peek” of preliminary research on the Eocene Thermal Maximum 3.

Non-Smithsonian visitors will be escorted to the Cooper Reading Room at 6:50 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.

Edward Gilbert, CPG, U.S. Environmental Protection Agency
Overview of Remediation Technologies for Contaminated Groundwater at Superfund Sites

Talk Abstract:
Groundwater is the main source of drinking water as well as agricultural and industrial usage worldwide. Unfortunately, groundwater quality throughout the United States has been degraded due to improper waste disposal practices and accidental spillage of hazardous chemicals. It is critical that the contaminated groundwater at hazardous waste sites across our nation be remediated in order to protect human health and the environment. EPA’s Superfund Program is responsible for cleaning up the groundwater at the nation’s most contaminated hazardous waste sites. The Superfund Program uses a wide variety of remediation technologies to ensure contaminants are either removed from the groundwater or are treated so they no longer pose a threat to human health and the environment. This talk will provide an overview of the most commonly used physical, biological, chemical, and thermal groundwater remediation technologies as well as some innovative technologies just beginning to be employed.

Speaker Bio:
Edward Gilbert is a Certified Professional Geologist with twenty years of professional experience in the characterization and remediation of contaminated groundwater at hazardous waste sites. Ed works within the Superfund Program at the U.S. Environmental Protection Agency as an environmental scientist/contaminant hydrogeologist. His experience includes groundwater monitoring network design and installation; groundwater flow and contaminant transport modeling; remedial treatability/feasibility studies; treatment technologies’ bench scale studies, field scale pilot studies, and full scale remedy implementation. Ed serves as a national expert/advisor in environmental earth science and on technical issues concerning the assessment, characterization, and remediation of hazardous substance releases, oil spills, and hazardous waste sites throughout the United States. In his present position, he is involved in the evaluation and promotion of innovative remediation technologies for the cleanup of hazardous waste sites. Ed holds a B.S. in Earth Science from Southern Connecticut State University and a M.S. in Geological Sciences from the University of Connecticut. He maintains certification as a Professional Geologist through the American Institute of Professional Geologists.

Fossil Dinoflagellate Cysts – A Tour of Applications for the 21st Century

Lucy E. Edwards

U.S. Geological Survey Reston, VA

Dinoflagellates are a fascinating group to study as fossils. This presentation will highlight recent applications and current advances in the study of the organism and, more importantly to PSW fans, its preserved fossils. Topics covered will include new twists on the old stand-bys: biostratigraphy, paleoecology, and taphonomy, followed by things like microbial preferences in cyst degradation, and what the ontogeny of cyst formation can tell us about extreme environments. Dinocyst humor will also be included.

Non-Smithsonian visitors will be escorted to the Q?rius theatre at 6:50 and 6:55 p.m. Society members will host the speaker for dinner at the Elephant & Castle (1201 Pennsylvania Ave.) prior to the meeting. Members may meet at the restaurant or inside the Constitutional Ave. entrance of the NMNH at 5:00 and walk to the restaurant as a group.

Janet Browne at U-Mary Washington 3/15

I thought that you might like to know that Janet Browne of Harvard University will be giving a talk on Charles Darwin in the Chappell Great Lives Lecture Series at 7:30 p.m. on March 15 in Dodd Auditorium in George Washington Hall on the campus of the University of Mary Washington in Fredericksburg.

A description of her talk: “By the time of his death Charles Darwin was one of the most celebrated — and one of the most notorious — scientists in the world. Today he is just as famous. Still controversial, Darwin has become an icon of modern science at the same time as his theories have become the basis of modern biology.
Professor Browne’s talk will explore how Darwin came to write the Origin of Species and its impact in Victorian England. Taking advantage of the magnificent archive of original correspondence located in Cambridge England, she describes how Darwin was simultaneously a public figure surrounded by controversy and a private family man with many friends and relations — and a succession of small children. The public and private were closely intermeshed in Darwin’s life, not always comfortably.”

The event is free and open to the public. For further information, visit:

Life’s Engines: How Microbes Made the Earth Habitable

The American Geophysical Union, American Society for Microbiology, and American Academy of Microbiology invite you to attend a lecture:

Life’s Engines: How Microbes Made the Earth Habitable
Paul Falkowski, Distinguished Professor, Rutgers University, Institute of Marine and Coastal Sciences and Department of Geology

When: Thursday, March 3, 2016 from 6:00 PM to 8:00 PM (EST)
Where: American Geophysical Union, 2000 Florida Ave. NW, Washington, DC 20009
RSVP: http://lifesengine.eventbrite.com
Free to attend

Details:
For almost four billion years, microbes had the primordial oceans all to themselves. The stewards of Earth, these organisms transformed the chemistry of our planet to make it habitable for plants, animals, and us. Speaker Paul Falkowski will take attendees deep into the microscopic world to explore how these marvelous creatures made life on Earth possible–and how human life today would cease to exist without them.

The lecture will examine the actual working parts that do the biochemical heavy lifting for every living organism on Earth. And Falkowski will explain how these miniature engines are built–and how they have been appropriated by and assembled like Lego sets within every creature that walks, swims, or flies.
