Dr. Denis Wiesenburg, professor of Marine Science at Southern Miss, presented a poster presentation titled “Phytoplankton Pigment Distributions over Fieberling Guyot” at the Hawaii Convention Center in Honolulu. The poster summarizes his research to gauge the effect of seamounts, or underwater mountains rising from the ocean floor, on phytoplankton levels above seamounts. Vanessa Wright, Southern Miss graduate student in Marine Science, presented a poster titled “Dynamics of Colored Dissolved Organic Matter (CDOM) in the Mississippi River Plume.” Wright said her research involved numerous cruises in gulf waters south of New Orleans, La. “We examined the seasonal variability of concentrations of CDOM from multiple cruises in the Mississippi River Plume and its relevance to remote sensing,” Wright said. Dr. Donald Redalje, professor of Marine Science at Southern Miss, presented a research paper titled “Evaluating Long-term Environmental Quality of the Bay of St. Louis, Mississippi.” Redalje and his team conducted studies of Hancock County's Bay of St. Louis in 1995-1998 and again in 2003, analyzing such measures as inorganic dissolved nutrients, pigments, oxygen, temperature and salinity in the water. They discovered that the bay acts as a single system with environmental quality varying as a result of storm events. Nadya Vinogradova, doctoral student in Marine Science, presented a poster titled “Shelf/Slope Exchange in the Mississippi Bight: Measurements and Modeling.” Vinogradova, who is completing work toward a doctoral degree in physical oceanography, was awarded “Best of Show” in her session for her poster. “The poster shows some results of my dissertation work in which I examine cross-frontal water exchange between the continental shelf and slope in the Mississippi Bight region,” Vinogradova said. Dr. Steven Lohrenz presented
research on harmful algal blooms titled “Hyperspectral Assessment
of Bloom Events of the Harmful Alga, Karenia Brevis.” Also
known as “red tide,” harmful algal blooms are essentially
high densities of marine plant life that occur with frequency along
the west coast of Florida and can have serious side effects for
surrounding organisms. Lohrenz describes his research team's efforts
to locate and track the species Karenia brevis using high-resolution
spectral and remote sensing technologies. Last
