How do I get to the Earth and Space Sciences Building at SUNY Stony Brook?


Geology Open night lectures are usually on topics in the geosciences related to the current research of the faculty, staff and students at SUNY Stony Brook. These presentations are intended for:

  • those interested in new developments in the sciences

  • earth science high school students and teachers

  • undergraduate and graduate students in geosciences

  • professional geologists

In-service Credit is available for teachers attending the Geology Open Night lectures.

 

You may also be interested in Astronomy Open Night lectures the first Friday of the month, The Worlds of Physics lectures the second Friday of the month and The Living World the third Friday of the month In-service credit is also available for teachers for attending these lectures.

A single point entry to all of the science open night lectures is available at this link

All of these lectures are in ESS 001 Lecture Hall


There will be Refreshments and Demonstrations after the Geology Open Night Presentations.

Admission is Free!!

Salt Water Intrusion and
Submarine Goundwater Discharge in Long Island

Professor Teng-fong Wong
Department of Geosciences
Stony Brook Universiy

Coastal ecosystems are among the most productive, yet threatened, ecosystems in the world. The quantity and quality of groundwater in these areas are related to the dynamic interplay of salt water intrusion and submarine groundwater discharge. The impact of their degradation often extends a long distance from the coast. The flux of nutrients and anthropogenic chemicals from terrestrial sources through groundwater discharge can exert subtle yet significant influences on the environmental health of many estuaries. Through advances in hydrological and geophysical techniques, the fluxes involved in these processes can now be characterized with relatively high spatial and temporal resolutions. Specifically we have employed a patented ultrasonic seepage meter to monitor submarine groundwater discharge and two types of electrical resistivity measurements to delineate the spatial distribution of salt and fresh water. Integration of these techniques have provided useful insights into the dynamics of salt water intrusion and submarine groundwater discharge, as well as their responses to tidal loading. Recent data acquired locally in the South Shore and Peconic Estuary Systems will be presented to illustrate these phenomena.

 Teng-fong Wong is a Professor in the Department of Geosciences, Stony Brook University. His research focuses on rock physics and fluid flow, with applications in earthquake mechanics, reservoir geomechanics and hydrogeology.

 

STRUCTURAL MINERALOGY ON SMALL LENGTH SCALES

Professor John B. Parise
Department of Geosciences
Stony Brook University

7:30 PM October 24, 2008 in ESS 001

Studies of minerals at the atomic scale are of fundamental importance. Studies that answer the question "where are the atoms?" allow us to understand, predict and modify the physical and chemical properties of materials, including minerals. Think about the differences between graphite and diamond: both materials are composed entirely of carbon and yet they have very different properties and uses. Graphite is a black conductor and used for lubrication. Diamond is an insulator, the hardest known substance and is used as an abrasive. For two minerals with the same chemical composition these differences are remarkable, and reflect the drastic differences in atomic arrangement of the carbons in their crystal structures. Over 20 noble prizes related to the endeavor of finding "where the atoms are" in materials as diverse as DNA, graphite, diamond are testimony to the enduring power and importance of the technique that unambiguously tells us about atomic arrangements. We’ll explore graphically how information on these materials is obtained and how it can be used.

I acknowledge the considerable contributions to this work of former and present graduate students, postdocs and collaborators, in particular L. Ehm, F.M. Michel, S.A. Antao, P.L. Lee, C.D. Martin, P. Chupas, K. Chapman, C. Tulk, D. Klug and B.C. Chakoumakos.

Professor Parise has been at Stony Brook since 1989, and has published over 300 papers in peer-reviewed journals and holds 4 patents. His research focuses on the structure and properties of earth materials under the operating conditions of Earth and planets. This involves considerable work at high pressures and temperatures, and conditions of the Martian surface, for example. He was recently recognized with the 2008 President of Stony Brook and the SUNY Chancellor’s award for excellence in scholarly and creative activities.

 

The Earth’s Super Cycles

Prof. Troy Rasbury
Department of Geosciences
Stony Brook University

7:30 p.m. November 21, 2008 in ESS 001

The sedimentary rock record is a chronicle of changes in the Earth’s tectonic cycles. These same cycles are temporally linked to evidence for major climate change which is in turn linked to major biological innovations and turnovers. Sedimentary packages record long-term rising and falling of sea level that are thought to be related to rates of sea floor spreading- with times of high rates of sea floor spreading being responsible for sea level rise. Times of high sea level correspond to times of warm climate (greenhouse) and times of low sea level correspond to times of cool climate (icehouse). Major faunal turnovers often occur at the transitions. Ocean chemistry, which is recorded in marine carbonates and evaporites, appears to have changed significantly and in concert with the greenhouse-icehouse changes suggesting a common driving force, plate tectonics. Since sedimentary deposits are produced due to changes in the Earth Systems, they are also an important (perhaps the only) way to examine the rates and scales of change. I will show the geological evidence for sea level change, climate change, and ocean chemistry change and will link these to the rock record for closure of Pacific-type subduction zones.

 

In-service credit available for teachers and professional geologists

If your school requires that you have a sequence of educational opportunities in order to receive in-service credit, please advise them that during the Spring Semester we will be offering one-hour of in-service credit for each of the:

Three Geology Open Nights
