"Monitoring Currents Along the Texas Coast: Fifteen Years of the Texas Automated Buoy System (TABS)"

In 1995 we began measuring currents along the Texas Coast using current meters that report data in real time through over the internet. This talk will describe the methods used and the results obtained after 15 years of operations.

"Flow through the Cayman Sea into the Gulf of Mexico: 1999 Observations"

In 1999 we conducted a cruise to the Cayman Sea. Part of that cruise involved a transect of the Yucatan Strait during which we made measurements using Acoustic Doppler Current profilers and CTDs. I will discuss these measurements and historical measurements of the northerly and southerly flow through the strait.

"Utilization of Buoys, Moorings, and Sensors in Real-time Ocean Observing Systems"

I will talk about the instrumentation we use and intend to use in ocean monitoring. I will talk about the longevity and fouling of different kinds of sensors and give some insight into how modern sensors may advance oceanographic research.

"Physical Oceanography at Gulf of Mexico Chemosynthetic Seep Sites"

These sites in 500-1000m water depth in the Gulf of Mexico, experience large temperature changes and highly variable currents. I will talk about measurements made by GERG scientists in the 1990's and discuss how these changes in water properties affect the stability of gas hydrates.

"Pollution of the Marine Environment"

General review of the history of contamination of the environment. Specific topics can be covered on request.(alternate J. Sericano)

"Atmospheric Deposition of Nutrients"

Discussions of atmospheric deposition by precipitation and dry deposition (e.g. dust) are discussed in relationship to two local estuaries, Galveston and Corpus Christi Bays.(alternate S. Sweet)

"Long Range Transport of Organic Contaminants"

The discovery of pesticides and PCB in Arctic biota led to research on the long range transport of contaminants by the atmosphere. Results of studies in , Galveston and Corpus Christi Bays will be included. (alternate S. Sweet)

"The "Mussel Watch" Concept and its Applicability to Global Chemical Contamination Monitoring Programs"

Although the use of biological monitors has become a standard practice in different national and international programs in the last two decades, there are several complicating factors -discussed here- that need to be taken into account when sampling over large geographical areas.(alternate T. Wade)

"The International Mussel Watch Program"

The objectives and results of the initial implementation phase of the international "mussel watch" program in Latin American countries are presented and compared to the data produced during the NOAA's national status and trends program in the U.S.. (alternate T. Wade)

"Bivalves as Bioindicators of Trace Organic Contamination in Coastal Environments"

Bivalves can be valuable bioindicators of environmental contamination by trace organic compounds only if their limitations are fully understood. The kinetics of the uptake and depuration of trace organic contaminants by field-transplanted and laboratory-exposed oysters is discussed.(alternate T.Wade)

"Chlorinated Biphenyls in the Environment"

Polychlorinated biphenyls (PCBs) are a class of 209 congeners highly persistent in the environment occurring in most human and animal adipose samples, milk, sediment, and numerous other matrices. An overview of their ubiquitous occurrence is presented.(alternate T. Wade)

"Planar Polychlorinated Biphenyls, Dioxins, and Furans in the Environment"

Dioxins and some related furans and planar pcbs are among the man-made chemicals subject to significant attention because of their high toxicity, high persistence and ubiquitous distribution in the environment.(alternate T.Wade)

NOTE: With appropriate notice more general, overarching topic areas and presentations can be tailored to your particular classes' needs.
