Welcome to New Orleans!
The University of New Orleans is pleased to host the 45th annual meeting of the South-Central Section of The Geological
Society of America . Our section includes ten U .S . and Mexican states, and for this meeting we have assembled 21 different
symposia and theme sessions . Symposia and sessions include topics such as coastal zone management, coastal processes, coastal
plain aquifers, southern North America Paleontology, the impact of the MC 252 oil spill, southern Laurentia lithospheric
evolution, modern and ancient deltaic geology, high temperature geochemistry, and shale geology . There are also three, premeeting
field trips that are being offered to highlight the geology of the north-central Gulf Coast and the many environmental
issues that are currently facing southern Louisiana .
Located on the banks of the Mississippi River, New Orleans has been a city of intrigue, history, and cultural diversity since
1718 when Jean-Baptiste Le Moyne de Bienville founded the city along the natural levees of the river . The city offers a wide
range of highly-rated restaurants, spectacular music, numerous museums, and a wide range of opportunities for shopping and
sightseeing tours . The local committee hopes that you take time during your visit to learn more about the city and how the
surrounding geology and environment has affected the development of southern Louisiana, influenced the cultures of the
region, and will impact the future of the area .
Enjoy the meeting!

Meeting Venue, Accommodations, and Dining
The meeting is being held in the Chateau Bourbon
Hotel, a French Quarter Wyndham hotel that is an easy
walk to the French Market, Jackson Square, Audubon
Aquarium, St . Louis Cathedral, Steamboat Natchez, Harrah’s
Casino, and Preservation Hall . Located in the heart of the
New Orleans French Quarter, the hotel was built in 1849
as the D .H . Holmes Department Store . This neoclassical
New Orleans treasure features French Quarter-style courtyards
and balconies above Bourbon Street . The Chateau is
a relaxing retreat in the soul of New Orleans that offers a
refreshing mix of vintage charm and modern chic, featuring
two restaurants, a courtyard pool, fitness club, business center,
concierge, wireless internet, beautiful meeting and event
space and airport transportation . Enjoy fresh seafood at the
Red Fish Grill, cocktails at the Clock Bar, or step out onto
Bourbon Street and explore French Quarter restaurants, bars,
clubs, shops and galleries .
History of the Chateau Bourbon Hotel
On 15 October 1849 Daniel Henry Holmes opened one
of the most important additions to New Orleans, the D .H .
Holmes department store . The store operated at the same
location for 140 years and became a local treasure, gaining a
national reputation as one of the outstanding retail establishments
in the United States . The City of New Orleans and
Historic Restoration Inc . joined together on a common mission,
to preserve and readapt the use of this historic building
by turning it into a truly unique 251-room luxury hotel .
The hotel opened in April 1995 . The transformation
of the pre-Civil War landmark into a 20th-century hotel
included a complete interior renovation and exterior restoration
to the building .
The famous “clock,” which was a favorite meeting place
for generations of New Orleanians, was missing since the
store’s closing in 1989 . The clock was returned to the hotel in
November of 1995 . The clock presently hangs in its original
location on Canal Street . Underneath the clock is the lifesize
bronze sculpture of Ignatius Reilly, funded jointly by the
hotel and the Downtown Development District . The statue
mimics the opening scene of the 1981 Pulitzer Prize winning
novel, A Confederacy of Dunces .
Some Visitor Safety Tips for New Orleans
Use common sense as you would in any major city . Do not
display large amounts of cash in public places . Avoid walking
alone on deserted streets at night as you would in any major
American city; travel with a colleague or friend if possible .
Trust your gut instincts . If someone or something seems suspicious,
leave the area or alert a police officer . If approached by
strangers for con games such as, “I bet I can tell you where you
General Information
got your shoes,” do not participate . Simply smile and walk
past them . Stow valuables out of sight in your vehicle . If you
drive to the city, it is best to park at the hotel to avoid parking
restrictions in popular tourist neighborhoods . If you have
been drinking, consider taking a taxi and do not walk home
alone after a night of drinking . Always go with a group when
touring any of the cemeteries . Most cemeteries close at 3 p .m .
Remember that most laws enforced in your city are enforced
here as well . New Orleans can be a very fun town, but there
are still many rules and regulations, so be aware of them!

local or regional groundwater systems or address problems
that affect groundwater resources, such as the migration of
saline waters and salinization of potable groundwater resources;
faults as barriers/conduits for groundwater flow; utilization
of groundwater in shale gas plays; and contamination from
landfills and other surface activities .
T9. Nanogeosciences in Mudrocks and Shale-Gas
Strata. Organizers: Farzam Javadpour, Jackson School of
Geosciences, The University of Texas at Austin, Austin, TX
Nanoscience is science at tiny scales . The high-tech
industry, such as microelectronic and biomedical systems,
has benefitted and continues to benefit from nanoscience .
Recently, nanoscale characteristics of natural systems have
ushered in a new era of nanoscience, including a new source
of fossil energy; i .e ., shale gas . Pores in these strata are at
the nanometer scale, and the physics of fluid transport in
the pores are different from those described by well-known
formulations such as the Darcy equation . Characterizing pore
networks in these systems and developing new formulations
for fluid flow in such systems are of great importance and
interest .

F1. Subsidence and Sea-Level Rise in Coastal Louisiana.
Depart 7 a .m . Saturday, 26 March, return 9:30 p .m . 28 March,
both to/from Chateau Bourbon Hotel . Dr . Torbjörn E .
Törnqvist, Dept . Earth & Environmental Sciences, Tulane
University, Cost: US$425 (ON, L, 2D), Max .: 12 .
The Louisiana coastal plain, including the Mississippi
Delta in the southeast and the Chenier Plain in the southwest,
belongs to the most vulnerable regions on the planet
due to accelerating relative sea-level rise . The accumulation
of strata in this area is strongly controlled by the interplay of
subsidence and sea-level change, and the Holocene record
presents an outstanding opportunity to study these processes
at a very high level of detail . The main objective of this field
trip is to highlight a number of investigations carried out over
the past decade that have led to new insights about rates and
causes of relative sea-level rise in this area, including the role
of subsidence and its spatial variability . Stops along the way
will focus both on the methodology (coring and sampling
techniques) of this work, as well as a discussion of key processes
(e .g ., glacio-isostatic adjustments, subsidence due to
deltaic sediment loading, compaction) that control relative
sea-level rise and coastal evolution in this region .
F2. Hurricane Katrina—What Happened? The Geology
of the Katrina Disaster in New Orleans. Sunday, 27 March,
8:30 a .m .–3:30 p .m ., depart and return Chateau Bourbon
Hotel, cost US$50 (L, D), Dr . Stephen A . Nelson, Dept .
Earth & Environmental Sciences, Tulane University, Max .:
25 . On August 29, 2005, Hurricane Katrina passed just to the
east of New Orleans . Storm surge from the hurricane caused
catastrophic failures of the levee system designed to protect
New Orleans form such a storm and resulted in flooding of
about 80% of the city . This field trip examines the levee
failures at several locations and discusses the role of the
geological and historical factors that led to the levee failures
and devastation . Vans will take the group to field trip stops
in the Lower 9 th Ward, Gentilly, and Lake View areas of New
Orleans . Lunch will be on the shores of Lake Pontchartrain
and participants will receive a printed field guide .
F3. Canoe Field Trip to Cane Bayou, St. Tammany
Parish . Sunday, 27 March, 11 a .m .–5 p .m ., depart and
return Chateau Bourbon Hotel, cost US$100, (L, D), Dinah
Maygarden, Pontchartrain Institute for Environmental
24 2011 GSA Abstracts with Programs
Sciences, University of New Orleans, Max . 15 . This is a
leisurely, four-hour paddle on a local favorite bayou which
offers abundant opportunities for bird and wildlife watching
as well as getting to know our wetland habitats . Cane Bayou
is a quiet, sheltered, slow moving waterway on the north
shore of Lake Pontchartrain bordered by Big Branch National
Wildlife Refuge and Fontainebleau State Park . From our
launch, the bayou winds for about a mile through upland forest,
remnants of cypress swamp (diminished in recent years
due to saltwater intrusion), intermediate marsh and shoreline
habitats . There are also excellent examples of Tchefuncte
era “middens” or shell mounds, approximately 3000 years
old . The area is rich in wildlife, including many species of
birds feeding in the varied habitats . Docile alligators may be
spotted, keeping their distance from paddlers . The shoreline
of Lake Pontchartrain is shallow and when conditions are
right, paddlers can enjoy a meal anchored on a sandbar about
100 yards offshore and dip net for small critters hiding in the
grass beds! The trip will be led by environmental science
educator Dinah Maygarden who will provide background and
information about the Pontchartrain estuary, its geology and
ecology and environmental issues affecting the wetlands and
Lake Pontchartrain .
