A physicist looks at Georgia tidal creeks
Dr. Jack Blanton
Georgia has some of the worlds largest salt marshes which are
connected to tidal creeks. The habitats of the creeks range between brackish and
salty and often one creek can experience both from time to time. The reasons
for this are connected to the high tides experienced along the Georgia coast
together with supplies of freshwater from rivers. Changes in either can alter
the conditions in the creeks and change the salinity of the water that bathes
the salt marshes.
A report card on mankind’s impacts on life in the sea
Dr. Peter Verity
There is compelling evidence that bioinvasions, harmful algal blooms, pollution,
chronic and acute diseases, and cases of overharvesting of natural resources are
increasing in frequency. It is now beyond doubt that many marine organisms
have begun walking the path to global extinction. This presentation will review
the evidence of humanity’s present legacy in the oceans, and where we will
likely be in 25 years.
An overview of the Skidaway Institute of Oceanography
Dr. James Sanders
SkIO is an internationally renowned research institute dedicated
to furthering our understanding of marine and environmental sciences while
training tomorrow's scientists. As an independent unit of the University
System of Georgia, SkIO serves as a gateway to marine environments and helps to
integrate marine programs throughout the state. Strong collaborative ties
with other USG institutions allow SkIO faculty to bring the latest in research
findings to the classroom; in turn, SkIO laboratories and vessels offer hands-on
research opportunities for students. International collaborations
regularly bring faculty and students from all over the world to our door. Learn
how SkIO's faculty and staff advance oceanographic research in our region and
worldwide.
Barrier islands and beach erosion
Dr. Clark Alexander
Barriers islands are dynamic features that are in a state of
dynamic equilibrium with their environment. This presentation covers the
geologic history of barrier islands in the South Atlantic Bight, the processes
that shape them on long and short timescales, the significant differences
between Georgia barrier islands and those found in Florida and North Carolina,
and the cumulative impact of our national desire to live near the coast.
Coastal ocean observing systems
Dr. Jim Nelson
The Skidaway Institute is a partner in a regional
program that is building an integrated observing network for the coastal and
continental shelf waters off the southeast U.S.; the Southeast Atlantic Coastal
Ocean Observing System (SEACOOS). The SkIO role in SEACOOS has focused on
installation of oceanographic and meteorological sensors at a set of U.S. Navy
towers on the Georgia continental shelf. The overall goal for SEACOOS is to
provide a regional information system serving weather service forecasters,
coastal and resource managers, offshore boaters, researchers, educators and
maritime commercial interests.
Culture of black sea bass for sushi market
Dr. Richard Lee
Successful studies continue on the development of a greenhouse based recirculating
system where black sea bass are grown to sushi market size on live tilapia juveniles
rather than pellets.
Earthquake hazards in the southeast US
Dr. Clark Alexander
Although the western US gets most of the press and attention when
earthquakes are mentioned, the east coast is far from silent. Two of the largest
historical earthquakes occurred in Missouri and a large earthquake struck
Charleston in 1886. This presentation covers earthquake mechanisms, the
differences between east and west coast quakes and discusses the history of some
of the large east coast quakes in the past 200 years.
Effect of human development on water quality issues in coastal Georgia
Dr. Peter Verity
Estuarine waters of Georgia and South
Carolina have historically been considered relatively pristine with respect to
environmental quality issues such as eutrophication, contamination, and
disease-causing organisms. However, land use impacts may begin without obvious
warning signs and become difficult to reverse by the time they are documented. Come and learn what is happening in your backyard now, and what may happen if we
do not pay attention to the warning signs.
Information services at the Skidaway Institute of Oceanography
Mr. John Cruickshank
Whether you have a quick question about oceanography or a related
subject or you are undertaking a major research project, our library has
extensive information resources and provides services that can help meet your
needs.
Satellite remote sensing of ocean color
Dr. Jim Nelson
Earth-orbiting satellite sensors are now among the
observational tools routinely employed by oceanographers. Among these are
satellite instruments that measure visible and infrared radiation. This
information is used to estimate a number of surface ocean properties, including
the biomass of microscopic algae, providing a regional to global scale view of
the marine biosphere. Our applications of ocean color imagery in the
continental shelf region off Georgia include tracking the transport of coastal
water masses to the deep ocean, identifying the timing and locations of
phytoplankton blooms, and detecting sediment suspension events during storms.
The greenhouse effect and the oceans
Dr. Rick Jahnke
There is a lot of misinformation circulating about the green house effect,
global warming and climate change. The oceans play a major, controlling role in
the build-up of green-house gases in the atmosphere. Learn more about this
controversial topic including how ocean ecosystems may be impacted and the
potential role of ocean circulation and biogeochemistry on future climate.
The ocean and global climate change
Dr. Stuart Wakeham
The ocean is closely linked to climate on a global scale. For example,
changes in atmospheric circulation influence ocean circulation which in turn
leads to the well-known El Niño events in
the Pacific Ocean and to variability in hurricane strength in the Atlantic
Ocean. The ocean also acts as a sink for atmospheric carbon dioxide which may
help ameliorate the greenhouse effect, global warming and sea level rise.
Research into aspects of the oceanic carbon cycle are directly related to a need
to understand the relationship between the ocean and climate change.
Use of grass shrimp for ecotoxicology work in coastal estuaries
Dr. Richard Lee
Studies, both in the field and laboratory, have linked exposure
of grass shrimp to various contaminants found in estuaries to reproduction
problems and DNA damage in their embryos. A team of SkIO scientists has
developed an assay
that allows one to quickly assay DNA damage in grass shrimp embryos exposed to
contaminants.
Who's who on the Skidaway Marine Science Campus
Dr. James Sanders
The SkIO campus hosts many partners all striving to promote
marine education and responsible stewardship of our coastal environment.
Get to know all about our campus and who else shares our passion for
investigating and protecting marine resources.
